Recovery snacks: ideas to boost your recovery

Recovery snacks are very important and can make the difference between you reaping the benefits of training and not. And so, our Christmas gift you is a special one-page factsheet with lots of  recovery snack suggestions.

Did you know that failing to consume some form of food or snack within 15-20 minutes of finishing training can severely delay recovery, prevent you from adapting and benefiting from the session, and can make you more susceptible to colds and infections?

The recovery snack should contain:

1. Carbohydrates to replace muscle and liver glycogen stores and to suppress cortisol secretion - This is one time when quick release carbohydrates (ie simple sugars) are ok, and often encouraged.

2. Protein to assist with muscle repair (and after a weights session to promote muscle growth).

3. Fluids to rehydrate (and perhaps some sale or electrolytes after prolonged training in the heat).

4. Vitamins, minerals etc to support the immune system (esp Vitamins C & E, Zinc, Glutamine & Probiotics).

Lots more information, and suggestions can be found on the Recovery Foods factsheet.

Milk.... The Perfect Recovery Drink?

Athletes of all abilities are looking for marginal gains, for the added extras that will improve their performance. When exploring marginal gains, diet is one of the first areas to look at. And athletes who are spending lots of time training, travelling and competing need to ensure they have a diet that is meeting their nutritional demands. They often turn to supplements as a quick fix to filling any nutritional gaps. Trying to fill these gaps with a natural source will not only be a cheaper approach, but may also be a healthier one, and some natural foods may also provide nutritional benefits beyond those intended.

Milk is one of these foods and may well be a suitable alternative to many sports drinks on the market. In terms of recovery products, there is none better than milk!

What is milk made up of?

Milk is a nutrient dense food containing lactose, proteins, fats, minerals, vitamins and water. Lactose, the major carbohydrate present, is essentially only found in milk. Milk contains a number of specific proteins, but the most common is casein, which compared to other proteins is very digestible in the intestine. Like eggs, milk also provides all nine essential amino acids. Calcium and phosphorous are the major minerals found in milk, and there are relatively small amounts of most other minerals required by the body, including zinc, magnesium, iron and copper. In addition, compared to other beverages, milk contains relatively large quantities of the electrolytes sodium, chloride and potassium. Milk contains varying quantities of many vitamins, including the fat soluble vitamins A, D, E, and K, found primarily in the milk fat.

Milk and performance

Due to issues relating to ease of consumption, the speed of release and the palatability of milk, it is less popular as a sports drink immediately before and during exercise and commercial sports drinks often become the preferred choice. But it's as a recovery drink that milk really comes into its own, and elite athletes often consume bottles of flavoured milk or milkshakes immediately after training or competition.

Post Recovery Nutrition

Many athletes will be familiar with the ‘golden window’, the period 30-60 mins immediately following exercise, during which nutrition can aid recovery. Refuelling correctly during this period is vital to those who may be training or competing more than once a day.

Recovery includes a number of processes, and milk can play a role in all of these:

1. Refuelling the muscle and liver glycogen stores (carbohydrate):

Athletes should aim for around 1g carbohydrate per kg of body weight to help refuel after exercise. Around 600ml of milk will provide 50g of carbohydrate, approximately the same amount as around 500-700ml of a sports drink (depending on the brand).

2. Replacing the fluids and electrolytes lost in sweat:
Athletes should aim to replace around 150% of their sweat lost during the 4-6 hours after training or competition. They should also replace the electrolytes lost in sweat, to ensure that fluids taken on board aren't just excreted in the urine. As well as being 87% water, milk is also a source of sodium, potassium and magnesium, all important electrolytes. Some but not all sports drinks contain electrolytes.

3. Manufacturing new muscle protein, red blood cells and other cellular components as part of the repair and adaptation process:
Early intake after exercise (within the first hour) of essential amino acids from good quality protein foods helps to promote protein rebuilding. Though research into the optimal type (e.g. casein versus whey), timing and amount of protein needed to maximise the desired adaptation from the training stimulus continues, most agree that both resistance and endurance athletes will benefit from consuming 15-25g of high quality protein in the first hour after exercise. Adding a source of carbohydrate to this post exercise snack will further enhance the training adaptation by reducing the degree of muscle protein breakdown. Around 300ml of milk contains 10g of naturally occurring protein and amino acids.

4. Allowing the immune system to handle the damage:
Ensuring adequate carbohydrate stores before exercise and consuming carbohydrate during and/or after a prolonged or high intensity workout has been shown to reduce the disturbance to immune system markers. The carbohydrate reduces the stress hormone to exercise, thus minimising its effect on the immune system, as well as also supplying glucose to fuel the activity of many of the immune system white cells. Milk provides a good source of protein and carbohydrates as well as a number of key vitamins and minerals to enhance the immune system and support overall health.

Milk can play a role in all the key recovery processes, is a naturally occurring product, supplies a number of key nutrients, and is cheaper than many sports drinks and recovery supplements. It could well be the best sports drink available!

Christmas and the Immune System

While we are on the theme of immunity and staying healthy over Christmas, here are a few pointers which may help with immunity during the busy festive time, when the normal training routine is often disrupted.

Christmas is the season to celebrate; there can be lots of late nights with visits and Christmas parties to be enjoyed. A lack of sleep, too much stress, eating poorly and being in contact with people who may be ill, all increase the risk of illness.

1. Stay hydrated

Make sure that you drink plenty of water as well as your other drinks so you stay hydrated and try to drink water as soon as you can when you wake up to rehydrate.

2. Plan when you train

With clubs and sports centres taking closed over Christmas, athletes often have greater flexibility with when they train.  Plan your training so that hard sessions don't follow late nights.  It's also a good idea to train in the morning before visitors and distractions makes you have to choose between doing your training and enjoying Christmas.

3. Moderate your diet

Some of the foods associated with Christmas do offer good nutritional content, its just about moderation and not over indulging in the bits - such as chocolates and sweets - which may have a lower nutritional content.

• Cranberries - High in Vitamin C, which is great for immity, and anti-inflammatories
• Turkey - Good source of protein and is often leaner than other sources of meat protein
• Parsnips - Excellent source of Potassium, which regulates hydration and is involved in muscle contractions
• Salmon - Sometimes an alternative choice at Christmas and a good source of omega 3 fats
• Carrots - Excellent source of antioxidants, beta-carotene, Vitamin A and Vitamin C
• Brussel Sprouts - Often a Christmas must - but are also a great source of Vitamin C
• Walnuts - Perhaps cracked open as a post-lunch snack - but a great source of Omega 3 fats

Fruit salad, dried fruit and salads are also good, nutrition-packed food options, which offer some protection against Christmas colds and viruses.

So enjoy your Christmas meal and the celebrations.

Immunity and the Athlete

Helping to maintain training during the winter months

An immune system which operates within homeostatic limits protects against common illnesses that can impair an athlete’s ability to train and perform.  Ensuring adequate carbohydrate and protein intake, a well as adequate intake of a wide range of micro-nutrients will help maximise the immune system's ability to protect against illness.  Improving immune health should be based around a five point plan:

1. Training - Load and Recovery

Adequate rest, alongside appropriate training, will ensure there is the right balance of overload and adaptation. Too much training with too little rest will lead to athletes becoming run down, and more prone to illness and injury. Sometimes, taking a day off when you feel run down or 'under the weather' may help prevent having to take a week of down the line.

2. Environment

There are some things that you cannot control, such as the training environment. However, you can be prepared. During the winter months, when the weather is likely to be colder and wetter, dress appropriately and keep warm whilst training and during warm up and cool down. Remember, just because it is cold, doesn't mean you don't sweat, so still pay attention to fluid levels and hydration, and ensuring that you shower and change out of damp clothing as soon as possible after training.

3. Psychology

High levels of stress and anxiety will also lead to a higher risk of illness. Try to reduce the risk of these feelings by focusing on things you can control, such as managing your time and meeting deadlines.

4. Lifestyle (Sleep, Diet, stress)

Be organised, ensure there is adequate rest and focus on healthy eating, meeting carbohydrate needs, adequately refueling, and choosing a wide range of fruits and vegetables.

5. Clinical conditions

There will be bugs and germs, and sometimes the sports environment is a perfect breeding ground for these to spread. Pay attention to good hygiene habits especially washing hands to reduce the risk. 

Supplements

Athletes can be quite quick to turn to vitamin and mineral supplements to prevent illnesses and time out of training. However. these should not be the first thing that the athlete looks to, and careful thought should be taken before this step is taken.

• What is the likely benefit of the supplement, or the likely harm?
• Are there any interactions between the nutrients, supplements and medications?
• What is the evidence supporting these supplements
• What is the cost, availability, and risk of contamination for the both the sport and the individual

In future posts I will look at some of the nutrients which are thought to reduce the risk of illness (including Vitamin E, Vitamin C, Vitamin D, Pro-Biotics, Glutamin, Zinc and carbohydrates), supporting claims for supplementing with these nutrients, and natural dietary sources for these nutrients.

Helping recovery from late training and competition

With more and more clubs struggling to get time in sports facilities, many athletes are face training, competition or matches late at night. I've known many swimming clubs have pool time 9-10pm (and then followed by a 7am morning session), and was recently expected to be on court for a match for 9.15. This provides an athlete with a few challenges- Motivation, fueling, and then recovery so that the athlete is able to train again efficiently the next day, especially if it is an early start.

So how can athletes best fit their preparation and recovery at this time at night in order to be able to train or compete at the best, and be able to recover quickly and effectively?

1) Be prepared- You will have a time table or schedule which will give you notice when these late sessions may be. Make sure you are aware of this, especially if its not frequent so you can get ready. Plan your day, and meals so that there is one less thing to think about.

2) Try to understand how long your body needs between a meal and training. Individuals will vary, but you should allow at least an hour between the meal and training time. If you know it will be an intense training session or match, try to have small snacks at regular intervals to top up energy levels. This would also apply to those who struggle to stomach meals before they have to train and compete, or those who suffer with nerves.

3) Be flexible with your meals. Perhaps have a larger, later lunch which is high in carbohydrate and then have smaller snacks closer to the game or training and after the match.

4) As its later, an athlete may struggle to replace their fluid needs before they go to bed. So athletes should try to ensure they start the match or training session hydrated as normal, paying more attention to taking fluid on board than they normally would. At the end of the match or training session, again attention should be paid to replacing fluid losses, taking a drink with them to bed that they can drink if they wake during the night.

5) Even though it is late, attention should be paid to a post recovery snack or meal. There may be little or no appetite, but in order to help recovery there should be something consumed immediately after which is high in carbohydrate to help restore carbohydrate used in exercise and a good source of protein to help muscle repair. This should be approximately 1g Carbohydrate per kg of body weight.

Some good choices for smaller recovery snacks before bedtime which are quick and easy:

• Healthy Breakfast Cereal and Milk 
• Milk and Banana
• Yoghurt and fresh fruit
• Wholegrain bread- as toast with jam. Or as a sandwich with a light filling
• Jacket Potato with filling- Tuna & Sweetcorn, Chicken, Baked Beans

Milk and Eggs: Nature's Best Recovery Foods

Over the coming months, as part of our nutrition theme, we'll be featuring some main food groups, outlining their role in sports nutrition, and sharing ideas of how they can be added to the diet. To kick us off, this week we cover milk and eggs, two of the best (and cheapest) sources of protein available.

Nature's best

Both milk and eggs contain all the essential amino acids in the correct proportions.  As the main food to sustain animal life before birth (eggs) and after birth (milk), it is unsurprising that both foods are nutrient rich.  In addition to protein, eggs are also a good source of vitamins B2, B12, D, E, folic acid, iron and a substance called choline which is involved in fat transport and in the production of phospholipids, an important component of cell membranes.  With a perfect blend of amino acids, as well as high levels of calcium (essential for bone health and the prevention of stress fractures), and other nutrients involved in metabolism and tissue growth, milk is the perfect recovery drink.

Unfortunately, despite their nutritional value, both eggs and milk have received bad press.  Eggs are high in cholesterol, though there is little evidence, if any, to link consumption of eggs with heart disease.  Milk is often advised against because of its high fat content, though a glass of full fat milk contains less saturated fat than a couple of biscuits.  Cow's milk is also, unfortunately, not tolerable by all, and dairy allergies and lactose intolerance is common.  Both foods do have important roles to play in the diet, and below we suggest some alternatives.

EGGS

The eggs of almost all birds, reptiles and turtles are edible, and most are eaten somewhere in the world.  Indeed, many are a delicacy.  The egg of the common hen, however, is by far the mostly widely available and commonly eaten egg in the West, and it is hen eggs that we will focus on in this piece.

The majority of the egg's nutritional value is found in the yolk, though the white is also a good source of protein, has no cholesterol, and contains very little fat.

Cholesterol and eggs

Eggs are high in cholesterol, but eating eggs doesn't usually contribute significantly to blood cholesterol levels; foods high in saturated fat have a much greater affect.  Egg are low in saturated fat, and egg whites don't contain any cholesterol, and can be used unsparingly in the diet.

Checking for freshness

Shops should only sell eggs less than 21 days old.  They are safe to eat up to 28 days, if kept in the correct conditions, though fresher eggs are better for certain dishes.  If you are unsure about the age of an egg, there are a number of ways of checking its freshness.  The simplest way is to place an unbroken egg in a glass of water.  Fresh eggs will sink straight to the bottom; older, but still safe to eat eggs will sit in the middle of the water, and old eggs, which should be thrown away, will float to the top.  The appearance of the yolk and white of the egg will change with age.  When broken onto a plate, a fresh egg will have two distinct layers to its white, and a rounded yolk.  The layers of the white merge and the yolk flattens with age.  The final test for freshness is the smell test.  Bad eggs have an unmistakable, unpleasant, sulphorus smell.

Storing eggs
The shell of the egg is porous, making it vulnerable to bacteria and odour contamination.  Storing eggs in their box, or in a special egg compartment in the fridge, away from fish, will help protect them from smells.  Fresh eggs can be stored in a well ventilated place, at less than 20°, for up to a week, or in the fridge for 3 to 4 weeks.  Refrigerated eggs should be brought back to room temperature before cooking.

Beaten eggs, in a container loosely covered with cling film, can be stored in the fridge for 1 to 2 days.  Whole, shelled eggs can be stored in an airtight container in the fridge for 1-2 days.  Egg whites can be frozen in an airtight container.  They should be defrosted in the fridge and used immediately.  Cooked eggs can only be stored if they are fully cooked.  Shelled eggs can be loosly wrapped in cling film and stored in the fridge for 1-2 days.  Hard boiled eggs which are left in their shells will develop an unappetising blue-grey ring around the yolk.

Egg safety
Some eggs may contain the salmonella bacteria, which, if not completely cooked or pasturised, can cause serious illness resulting in abdominal pain, vomiting and diarrhea. Mayonnaise, ice cream and mousse are based on raw eggs.  While commercial versions of these product use pasturised eggs, home-made versions may carry a salmonella risk. At-risk individuals (children, pregnant women, the elderly), as well as athletes in the run-up to an important competition, should minimise their salmonella risk, and avoid raw or undercooked eggs.

Cooking eggs
Eggs' real value comes in their versatility.  They can be boiled, fried, poached or even baked on their own, mixed with some milk and seasoning (and optional other ingredients) and scrambled, or simply turned into an omelet.  They can be eaten hot or cold, and used to increase the protein content of a number of dishes.  They also form the basis of quiches, frittatas and tarts.  Egg-based recipes such as quiches and omelets are also a great way to use up leftovers, though beware of the high saturated fat content of any recipe using pastry.

While frying is the simplest way to cook an egg, it's also the least healthy option, because of the fat involved in the cooking process.  Poaching or boiling are much better options.  Poached egg on toast makes a simple, cheap and nutritious recovery snack, while cooked hard boiled eggs are a great addition to salads and sandwiches.

The Bord Bia (Irish Food Board) website has a range of great egg recipes that you might like to try.

MILK
Cow's milk, with its slightly sweet, mild and subtle flavour is the most popular form of milk used for human consumption, though the milk of other animals, including goats and sheep, and milk made from plants such as soya, rice and almonds can also be consumed.  Commercially available milk usually comes from Frisian cows, though the milk of Jersey and Guernsey cows, richer in flavour, higher in fat and darker in colour, is also popular.

Recovery food
As mentioned previously, milk's perfect balance of protein makes it an ideal recovery drink.  It also contains some sugars for refueling, and a lot of water and the electrolytes sodium and potassium to help with rehydration.

Milk makes a tasty recovery drink on it's own, as part of a banana or chocolate milk-shake, or added to a fruit smoothie.

Milk and saturated fat
Full fat milk has gained a lot of bad press, particularly in relation to it's saturated fat content.  While it is true that whole or full-fat milk contains just over twice the fat content of semi-skimmed milk, it's worth putting the fat values into context.  A 200ml glass of full fat milk contains 7.8 g of fat; approximately the same as two chocolate digestive biscuits.  Semi-skimmed milk is a good choice, as it has approximately the same protein, carbohydrate, vitamin and mineral content as whole milk, with half the fat, but those who prefer the taste of full fat milk shouldn't get hung up on it's fat content - just skip one of the chocolate digestives instead!

Skimmed milk typically has half  the calories, a fraction of the fat and most of the vitamins and calcium of full fat milk, but is low in the fat-soluable vitamins A and D.  It is therefore not suitable for young children.

Alternatives
Goat's milk is a good alternative for those with a diary alergy.  It has a stronger flavour and is less widely available, but has a similar nutritional content, is easier to digest and contains less lactose than cow's milk.  Soya milk, made from pulverized soya beans, is suitable for vegans and those with lactose intolerance.  It has a thicker consistency than cow's milk, and has a slightly nutty flavour.  It curdles in very hot coffee and tea.

Buttermilk, traditionally made from the thin, unstable liquid left over after making butter, but more recently made from fermented skimmed milk and milk solids, is particularly low in fat.  It is, however, not to everyone's taste.

Storing milk
Milk should be stored in the fridge.  It usually lasts no more than 3-4 days in the fridge after opening, irrespective of its use-by date, and can quickly sour when the weather is very warm.

Calcium and iron - not the perfect mix
Calcium is one of the substances which can affect iron absorption.  To maximise absorption, avoid drinking milk at the same time as you take iron supplements or eat iron rich foods.

Nutritional Considerations for Ultra-Endurance Events

Participation in ultra-endurance events has been increasing as cycling, Ironman triathlons and running events are all becoming popular challenges for people to test their physical limits. So when my partner asked for nutrition advice for his 12hr Time Trial event, I thought this could be a good topic to blog about.  I have split the topic into two sections - the first will look at the physical challenges the body faces when being put through ultra-endurance events and the second will look at the nutritional strategies that athletes can use to ensure they achieve their goals.

By definition, an ultra-endurance is an event which last over 6hrs in duration, and the athletes who are successful are those who have the ability to sustain higher absolute speed for a given distance than the other competitors. The three main demands which are placed on the body during this time are:

• Meeting energy demands
• Maintaining body temperature
• Replacing fluid and electrolyte loss

Alongside that, there are increased injury and immune function risk after the event has taken place, and these have to be managed.

Hyperthermia - Maintaining Core Body Temperature

As well as supplying oxygen-rich blood to the body, the heart helps control body temperature by pumping warm blood to the skin where body heat is lost through the evaporation of sweat. During prolonged periods of exercise, heat is produced and increased heat loss needs to occur through sweating to maintain a constant body temperature and body functions.

There are certain factors which can prevent or reduce sweating and heat loss - high humidity can reduce evaporation and dehydration can impair the ability to transfer heat from muscles to the skin. In both situations, the increase in the core body temperature will increase the risk of heat problems. Muscle weakness and disorientation can develop with smaller increases in body temperatures with more serious effects occurring as the body temperature rises. Ways in which an athlete can maintain a constant body temperature will be looked at in the next blog.

Hyponatremia - Fluid and Electrolyte Loss

In recent years, it has been suggested that dehydration in marathon runners is over emphasised and results in some runners suffering with hyponatremia. During exercise, electrolytes, as well as fluids, are also lost in sweat.  Sodium and potassium are the main two electrolytes lost and need to be replaced at some point, depending on the duration and intensity of the event. 

Hyponatremia is the dilution of sodium levels in the blood often caused by the consumption of too much fluid and not replacing the lost electrolytes in sweat. This eventually causes swelling of the brain which can be fatal and has been reported during marathon events in recent years.  This is more common in slower runners who have more time to drink, and are often encouraged to do so. Ways in which athletes can maintain their electrolyte levels will be discussed in the next blog. 

Glycogen Depletion

Carbohydrates are the main energy source during endurance events and provide energy to the muscles at a rate which can sustain a fast pace optimal for performance. Carbohydrates are found as glycogen in the muscles and liver and as blood glucose. As blood glucose is used up, the body converts glycogen into glucose and releases it into the bloodstream to maintain a constant supply of energy. However, glycogen stores are and can only sustain a high work rate for about 60-90mins. If carbohydrates are not replaced at or before the point of glycogen depletion, the body must turn to other energy sources to maintain this work rate. The main alternative source is fats which can sustain exercise for much longer than glycogen, but at a much slower rate. It is much harder to maintain the same pace following the shift in fuel source, a point which is often known as ‘bonking’ or ‘hitting the wall.’ It is important to maintain levels of muscle glycogen and blood glucose for as long as possible. Ways to do this will be discussed in the next blog.

Injury and the Immune System

Due to the length of time an athlete will be performing the same activity and the same action over and over again, there is going to be a considerable amount of stress placed on certain muscles, bones and other soft tissues. Muscle damage and inflammation can remain for several days after completion of the event, and tissues can take much longer than normal to fully repair. Even while the athlete may be celebrating completing the event or achieving their goal, there are a number of things which they can do to aid recovery and prepare for the next training session or event.

As well as the muscle damage, as part of the repair process, cytokines are released from the injured area to promote an influx of white blood cells from the immune system, and these remain elevated following prolonged exercise.  However, there are other markers of immune function which are lower after completing an endurance event, leaving the immune system less able to protect the body from infections. This is why many athletes become ill after endurance events or high intensity training. There are certain practices athletes can do to ensure that both injury and muscle soreness can be reduced and this will be looked at next time.

What should you drink?

Continuing the blog on hydration, I thought I would look at the different types of drinks and when they may be useful in different situations.

When training or exercising, athletes need to consider the intensity of their session, the duration of the activity and the environmental conditions, and how these may affect their sweat rates. For example, if their session is a light aerobic session in a cool environment, their sweat rates and energy needs are going to be lower than if they were training at a high intensity on a hot summer's day.

Some sports have very little change in environmental conditions such as swimming or indoor sports, whereas some sports involve varying conditions and therefore athletes need to understand how their body responds to different conditions and be prepared in order to ensure they maximise their training and recovery.

There are three different types of drinks, based on the solute concentration and their osmotic pressure. 

Hypotonic - generally contains less than 4g of carbohydrates per 100ml. It provides little energy, but will be taken up by the body quickly, and therefore ideal for recreational sports or shorter or less strenuous exertion.  Examples include:

• Water
• WeakCordial 

Hypertonic - this type of drink generally has more than 8g of carbohydrates per 100ml and greater osmotic pressure than bodily fluids. Its main aim is to supply energy and the fluid is taken up more slowly than water. Ideal use is 30-60 mins before exercise and immediately after sports.  They are also useful for athletes who find they need a bit more energy.

• Milkshakes
• Smoothies
• Concentrated Fruit Juices 

Isotonic - this type of drink contains between 4-8g of carbohydrate per 100ml and has about the same osmotic pressure as bodily fluids. An Isotonic drink is taken up by the body about as quickly as water and they are intended to help hydration and provide energy.

• Sports Drinks
• Squash

Also considering the different times athletes may need to choose different drinks. 

Before Exercise - The main aims are to ensure the athlete is hydrated before exercise, as athletes will be able to meet energy needs through solid foods, therefore a hypotonic drink such as squash or water will be adequate. If it is prior to competition, and athletes struggle to eat, then isotonic drinks can help meet energy requirements while making sure athletes are hydrated. 

During - This will be dependent on the training programme. Many athletes will be fine with a hypotonic sports drink replacing fluid loss and athletes should choose drinks which are palatable to encourage consumption. However, if the training session or competition is high intensity and longer than 90 min, some athletes may need to include some energy, therefore an isotonic drink will meet an athletes needs. Other ways to meet this need if athletes prefer to drink water is to take a high carbohydrate snack to have alongside training which can be consumed at an appropriate interval. 

After - The session type and environment conditions will influence the athlete's choice of drink. After a  high intensity session, it is going to be important to replace energy and fluid needs. If an athlete is able to eat immediately after a session, a high carbohydrate snack alongside squash or water should be sufficient to meet their needs. However, if an athlete struggles to consume any food following a training session, a hypertonic drink which is high in carbohydrate will be able to support this. This is why many athletes now choose to drink milk or milkshakes after a training session. Athletes should be aware of when their sweat rates are high and make sure they adequately replace their fluid intake in the hour after a training session.

Athletes can monitor their hydration by comparing to a pee chart, a simple indication of their hydration status, with the idea to be on the paler side of the chart.  One of the main things is to to be happy and comfortable with what you drink. It could be the best drink which will help performance, but if the athlete doesn't like the taste they probably won't consume as much as is needed. 

Simple, nutritious smoothies and juices

The recent spell of fine weather has inspired me to get back into smoothie-making mode.  Summer months are an ideal time for smoothies as the seasonal berries provide a tasty addition, though this week I have been using the end of last year’s blackberries and loganberries from the freezer.

Smoothie and juice making can be as simple or as complicated as you make it, and the fruit (and vegetables) that you use is only limited by your imagination.  Rolled oats, ground almonds, sesame seeds, and peanut butter are just some of the other ingredients that you can use.  Milk, yogurt, coconut milk or almond milk can be used to add extra smoothness and increase the protein content, and nutmeg or ginger will give an extra kick to any juice.

Smoothies are high in vitamins and minerals, a great way of getting some or all of your 5-a-day, and are higher in fibre than traditional juices because they retain the pulp and skins.  They are also easier to make, and don't produce waste.  Smoothies are a particularly easy way of getting vital calories and nutrients in after a hard session on a hot day when you might not feel like eating food, and they can help to rehydrate you (read last weeks blog about hydration here).  Many fruits also contain natural chemicals which help increase appetite.

This is my basic go-to smoothie recipe

• Apple (cored and quartered) and/or banana to give it a nice texture and adds thickness
• Orange juice to make it more runny.  You can also use pineapple or apple juice, and if you have a juicer you can make the juice yourself.
• Frozen raspberries, blackberries, loganberries or similar berry to give it taste.  The frozen fruit means that the smoothie is already cool.  Add some ice cubes if the fruit is fresh.
•  Blend all the ingredients together in a blender for 30-40 seconds.Server more or less immediately.  Mind the brain freeze.

Like all my recipes, I don’t get too hung up on measurements.  I go with what I think is roughly right, and if it’s too thick, I just add more orange juice. If it's not thick enough, I add another apple or banana.

You don’t have to follow any particular recipe to make a great post-training snack or a nutritious drink to kick-start to the day.  Add something to give it texture, something to give it juice, and something to give it taste, and focus on what’s available to you at a reasonable price.  

And smoothies don’t have to be expensive.  Pick blackberries in the late summer (they’re free in most hedgerows!) and freeze them to use throughout the year.  Because any fresh fruit you add will be high in vitamin C, you can use 'from concentrate' juices to keep the cost down.

Smoothies are a great way of using up ripe fruit.  If you have bunches of bananas that are getting ripe, you can peel them and freeze them for use in future smoothies.

Juicing require more cleaning up afterwards.  Fruit and vegetables need to be very ripe, and some produce little juice, creating a lot of waste.  If using frozen fruit, ensure that you let them thaw first, or you'll end up with a lot of waste and practically no juice at all.  Juices can be diluted with refrigerated mineral water or sparkling water.

Any sort of blender will suffice for making smoothies, though there is a range of juicers and smoothie machines on the market.  Smoothie machines have some additional features over traditional blenders: a pouring spout, durable blades for crushing ice, and a pusher to ensure that the fruit and vegetables are all blended properly.  Juicers actually separate the juice from the pulp, skin, seeds and other debris, creating a large amount of waste, but providing a great way to make your own orange, apple or pineapple juice. Masticating and hydraulic juicers are more efficient (i.e. produce more juice) than centrifugal juicers, but are also more expensive. A number of other fruit and vegetables work well as juices, and in most cases, combining juiced fruit with blended fruit will give the best results.

Post Marathon Recovery

As the dust settles on the Virgin London Marathon which took place on Sunday, thousands of runners will be taking a well-earned rest after the months of long and hard training needed to met their goal and complete the challenging 26.2 mile distance.

During their training period, many runners will have experienced at least one occasion where they were unable to train due to a cold or flu like symptoms. Like many other endurance athletes, some will have suffered from repeated bouts of infections which caused a real disruption to their training routine and ultimately their performance. Suppressed immunity is common during and following periods of hard training, and athletes often pick up an illness shortly after a marathon or major race. In addition to allowing the mind and muscloskeletal systems to recuperate, the recovery period should aim to boost the immune system.

There are many theories as to why immune defence is weakened following strenuous endurance activity. Athletes with a high training load (more than 11h moderate intensity training per week), experience more than twice as many upper respiratory tract infections compared with those on low-moderate training volumes. So how can athletes help maintain their immune system and prevent the training disturbances caused by bouts of illnesses?

Here are a few starting points:

• Stay hydrated and try to rehydrate effectively as soon as possible post training or competition. This will help maintain saliva production and sustain the release of saliva proteins know to have important antimicrobial properties.
• Ensure sufficient rest - don’t return back to exercise too quickly and maintain light exercise until fully recovered.
• Ensure that you get adequate sleep (at least 7 hours per night) in order to help your body to recover and repair any damage that has occurred.
• Keep away from people suffering with cold or flu where possible, or reduce physical contact.
• Maintain good hygiene e.g. washing hands regularly.
• Promote recovery as much as you can - try to consume a good quality carbohydrate snack within 30mins post exercise. This may mean athletes need to be prepared by packing light snacks to have after training. Sometimes waiting until you get home is too late and can often lead to poor food choices.
• Forward plan to ensure that you have access to foods appropriate to meeting nutrition goals for training. Plan and prepare meals so that when you go grocery shopping you can ensure that your cupboard is full of things you need for healthy meals.
• Choose a wide variety of foods within your diet - each food has a different range of nutrients; the wider the choice and range of your foods, the more different nutrients you will consume.
• Include cereal rich foods such as wholemeal, multi-grain or seeded breads, brown rice or pasta. Athletes who are training for endurance activities need to maintain a high carbohydrate diet to support their energy needs and help their body to recover efficiently.
• Eat a wide variety of fruits and vegetables throughout the day - the more colour the better.

The Benefits of Sports Massage on General Health and Sports Performance

All sportsmen and sportswomen should consider building a regular Sports Massage into their training routine whether they are injured or not. Sports Massage has a number of physical, physiological and psychological benefits and can help keep the body in better condition, reduce the number of injuries, improve mobility and flexibility and help reduce the likelihood of fatigue.

Sports massage can achieve a number of different benefits depending on the client’s needs; for example someone with tight muscles may be able to improve flexibility after treatment, someone who is stressed may feel more relaxed and someone suffering signs of fatigue may see improved  recovery.

The Physiological Effects of Sports Massage
Utilising natural blood flow, massage can have a significant effect on the micro-circulation through the pressure and movement of the strokes, helping to flush out any muscle waste and stimulate osmosis.  This improves recovery, aids metabolic processes and improves tissue health. Massage also improves the flow of the lymphatic system and therefore helps drainage removing waste from the system, and can strengthen the immune system due to the increase in white blood cells. 

Sports massage can also have a significant effect on the nervous system through stimulating the sensory receptors and either stimulate or soothe nerves depending on the techniques used. Sports Massage can also stimulate the parasympathetic nervous system, helping promote relaxation and reduce stress, and can help reduce pain by the release of endorphins.

Due to the effect on the circulation, Sports Massage can improve skin condition due to cell regeneration from the increase in nutrition to the cells. It can help with the removal of waste products through the increased production of sweat and through increased sebum production. Sports Massage can also help improve the skins suppleness and elasticity. 

The Physical Effects on the Body
During the body’s healing process there is the formation of scar tissue. This is normally broken down but sometimes (more common with soft tissue injuries), some can remain. Adhesions can form from this scar tissue and this prevents the fibres ability to glide alongside one another which is needed for them to function.

Massage can help restore the range of motion by helping to release the restrictions by breaking down this scar tissue and helping to free the adhesions. It can also reduce inflammation, and reduce muscle tightness, stiffness and spasms.

Massage can help increase joint mobility by reducing the thickening of the connective tissue and help to release the restrictions. It can also help to free adhesions, break down this scar tissue and reduce inflammation, thereby restoring the range of motion.

By increasing blood circulation and oxygen and nutrient supply to the muscle as well as promoting removal of toxins and waste products, Sports Massage can also reduce muscle fatigue and soreness. 

The Psychological Effects of Sports Massage
Sports Massage can help to reduce stress and anxiety through relaxing both mind and body, promote positive body awareness, improved body image through relaxation and ease emotional trauma through relaxation.

Lifestyle management at altitude

Altitude training is forming an important part of the training programmes of many endurance athletes.  Living at altitude can pose a range of challenges, however, and particular aspects of lifestyle may need additional attention, particularly in relation to preventing overtraining and boredom.

Athletes may become lethargic because of the boredom, and those who fail to embrace the local culture may regret missing out on potentially inspiring and enjoyable experiences.  It would be a shame to fly all the way to South Africa, and never to see and animal in the wild!

Conversely, those to try to fit too much in, fail to recover adequately from training.  Attempting to fill the time between training with some more training will lead to burnout.  You could get addicted to computer games (or sudoko, strib scrabble, or poker for training kit) and delay or skip training as a result.  Spending all day visiting sites and attractions, may result in sore feet, tight muscles and increased risk of injury.

If you fill all your spare time with sleep, and may generally lethargic, or become unable to sleep at night.  You will need more sleep than normal at altitude, and afternoon naps are not only acceptable, but generally recommended.  But oversleeping, or sleeping to kill time may be detrimental to your training.

Spending all your time sunbathing isn’t the answer either.  The sun’s UV rays are stronger at altitude, and you will be more susceptible to sunburn than at sea level. 

You could also dragged into other people’s routine.  Having other people around you is a good thing, but remember that everyone responds to altitude different, and you may need more recovery time than others.  Finally, spending too much time with your friends or training partners can lead you to getting on each other’s nerves.

Of course, these factors may be similar to the challenges that full-time athletes face in their everyday lives.  We will revisit the pros and cons of being a full-time athlete in a future post, but in essence, athletes become full-time athletes when they go away on training camp, and that can have positive and negative aspects. It isn’t all bad of course, but care must be taken to not slip into the many pit falls.

Don't miss out on the opportunities that training abroad can offer

The training camp mentality

Training camps can be a great way of injecting a new impetus into training.  A new environment can be energising and brief, intense spells of training can help athletes reach a new level.  Athletes tend to be more motivated when they are training in a group and have no other distractions.  Training camps are not without their pitfalls, however, and being over motivated can be particularly detrimental when it comes to training stints at altitude.

Taking time to acclimatise to altitude can be the key to a successful training camp.  Too often I hear people saying that they’ve done their hardest ever week of training or hit new ‘personal best’ mileage figures while training at altitude, or tweeted about how much running at altitude has ‘kicked their asses’.  

At sea level, training in a group can help stretch most athletes to achieve their best.  Occasionally trying to keep up with better athletes can sometimes reap results.  Training in a group at altitude, however, is generally a bad thing.  Every athlete respond to altitude differently, and in addition to risking your physical health by working too hard, competing and measuring yourself against others can have detrimental effects on your mental performance. 

Key advice

• Work out your own programme with your coach and follow it
• Monitor your HR, RPE and general wellbeing, and adapt your programme if required
• Remember that less is more.  Just because you’re away on training camp, doesn’t mean that you have to train all the time.  Recovery is part of training too.
• Don’t get dragged into the group mentality
• Avoid going away with training partners that are overly competitive in training

Rest and recovery

We’ve all heard that resting is training too, but nowhere is the sentiment more true than when training at altitude.  Most of the physiological adaptations that occur at altitude, actually happen at rest.  Living at altitude is far more important than training at altitude (unless of course your training to compete at altitude). 

Basic acclimitisation to altitude takes approximately 14 days, though this varies depending on the individual.  During this time resting and training heart rates will be elevated, recovery times between intervals will be significantly increased, and more sleep will be required.  Your body will be working hard to increase EPO secretion, build new red blood cells, and to respond to the acute effects of the lower air pressure and oxygen availability.  Sometimes it’s best to just let the body get on with that.

Key advice

• Reduce overall training volume by 10-20 percent during the first week, and increased gradually over the next three to four weeks.
• Reduce the intensity of interval sessions by 5-10 percent initially, and increased gradually.  Intervals should be shorter than normal, and recovery time between them doubled. 
• Take an additional recovery day between hard workout days.  Use resting HR as an indicator of recovery, and skip any planned workout if the HR is elevated more than normal.
• Remember that there are huge individual variations in response to altitude.  Listen to your own body and don’t measure yourself against others.
• Remember, with altitude training, less is more, particularly during the first two weeks.

The boredom factor

Boredom can be an issue when training at altitude, and striking a balance between killing time, relaxing, and embracing the sites and culture of your training environment, can be difficult.  Boredom can lead to depression, so susceptible athletes should take particular care.

If you’re in charge of your own travel plans, choose somewhere that will cater for your entertainment needs.  If you don’t like sitting around all day talking and drinking tea, then Kenya may not be for you.  Choose a big city if you like to have lots to do; and smaller towns if you prefer to be close to nature.

Key advice

• Decide on one or two things that you would really like to do while you’re away, and then decide where those activities will best fit into your training programme.  A safari might be a good way to recover from a long haul flight and adjust to altitude, while a trip to the grand canyon might be a suitable activity for a rest day. 
• Have one worthwhile task to do while you’re away. Catching up with university work, doing an online course, writing blogs or magazine articles, or updating your website are just some of the projects that you could complete.
• Enjoy your mealtimes; it’s not every day that you can take your time eating food.  Dining halls are also a good way to meet new people, and to soak in the culture of your surroundings. 
• Not everyone loves to eat, sleep and breathe their sport.  Find what works for you and plan accordingly.

Nutrition and staying healthy

Diet is very important when training at altitude, and adjustments may have to be made to ensure that you are getting all the nutrients that you need.  

Since more oxygen is required to break down fat than carbohydrates, 80 percent of calories should be derived from low glycaemic carbohydrates.  Meals should be taken every 4 hr.  Increased carbohydrate utilization may result in glycogen store depletion, so make a conscious effort to replace carbohydrates during and after training.

Reduced nutrient absorption in the gut at altitude results in greater faecal losses.  Maintaining a high proportion of carbohydrate, and ensuring that overall calorie intake is adequate may reduce or offset this faecal loss.  Basal metabolic rate increases for the first 4 days of altitude exposure, particularly in females.  After 4 days metabolic rate begins to return to normal, but remains above sea level values. 

Some individuals may experience reduced appetite.  Small but regular meals, and eating a variety of fresh products, may help.  Apples and grapes in particular have natural chemicals which increase appetite.

 Iron is also very important and depleted iron stores is one of the reasons why some people do not respond to altitude.  Iron is a mineral that is essential in the production of haemoglobin.  Haemoglobin is the part of the red blood cell which attaches to oxygen and transports it around the body.  As the body turns iron stores into additional red blood cells in response to the hypoxic conditions and subsequent increased erythropoietin syntheses, the demand of iron rises, and with it the risk of developing anaemia, even in health runners.

There is risk of immunosuppression, and a subsequent increased risk of upper respiratory tract infections and gastrointestinal infections, at altitude.  It is important that you listen to your body, have adequate vitamins (A, folic acid, B₆, B₁₂, C and E) and minerals (copper, selenium and zinc) in your diet, and replace carbohydrates quickly after exercise.

Because of increased ventilation, increased urinary water loss, and low humidity at altitude, the potential for dehydration is increased.  Caffeine-free fluid intake should be increased by as much as 4 litres per day.  Monitor morning urine colour to ensure that fluid needs are being met, and reduce caffeine consumption.

Dealing with Injury

If you are training at altitude, and get an injury that prevents you from carrying out your normal training, it is best not to panic.  Depending on the severity of your injury, how far you are into your trip, and on the duration of your planned trip, you have a number of options.

The most important thing is that you get treatment for your injury.  If you do not have support personnel with you, cannot find access to a suitable physiotherapist, and do not know what your injury is and how to treat it, you may be best taking complete rest.  If you have a long trip planned, you could look at shortening your trip.

Even if your ability to train is severely hindered by your injury, you will still benefit from sleeping at altitude.  If you would have to rest even if you were at home, you may still be able get some benefit from your trip, and the solitude of altitude may help with adherence to rehab exercises.

Cross-training may be particularly beneficial at altitude and cycling, aquajogging, or even just walking, may be sufficient to raise the heart rate to sea level easy exercise levels in some individuals.

If you are susceptible to injury, or have a recurring injury, ensure that you have access to physiotherapy, and/or medical backup, have access to cross-training facilities if required, and have investigated if the trails are suitable for you.

If all else fails, and if it’s not practical for you to go home early, consider that your injury may be your body telling you to take a break.  Consider if you actually need a holiday.  Make a conscious effort to make the most of the trip, and add in some extra sightseeing, make some new friends, and relax.  Make the most of the hypoxic air!
