What you need to know about staying hydrated!

We have all heard the importance of hydration. We have all been told how important it is to stay hydrated in order to perform optimally. Advice surrounding hydration always seems extremely generic. Why is hydration so important and how should we actually hydrate? Very seldom is this discussed with athletes.

Hydration is important as water is involved in almost every bodily function. When the body functions optimally it can perform optimally. If it is not functioning well then any stress applied to it is magnified. That is the short explanation as to why we should hydrate. Most will understand basic biology and the concept of osmosis. Solutes and water diffuse across a membrane from areas of high concentration to areas of low concentration. In regard to the body we have many forms of these membranes, the simplest being the membrane which surrounds all cells. Water is needed for many cell activities including cell metabolism, without which a cell would cease to function. The science behind cell metabolism is fascinating in itself but not all that practical for the majority of athletes.

For endurance athletes cardiac output is a critical factor. This is a product of heart rate and stroke volume (Blood volume ejected from the heart with each beat). Blood is mostly made up of water. In cases of dehydration blood plasma volume is reduced as water is excreted through sweating etc. Water and its role during sweating is the most effective element in heat management. If our plasma volume reduces there is reduction in overall blood volume as red cells become more concentrated in less plasma. This results in the heart having to work harder to pump enough blood around the body. This increase in workload is pointless additional stress for the body. It is purely a mechanistic result of water loss from the blood. It will cause a reduction in cardiovascular capacity and overall work capacity. Similar effects occur at altitude in an effort to combat reduction in oxygen pressure in the ambient air. The body increases hormones which excrete water to concentrate the blood, as less oxygen is being absorbed into the blood with the reduction in pressure.

The stomach is a key organ in the process of hydrating. Water is one of the few substances that can be absorbed by the lining of the stomach. In saying that water is also essential downstream in the small intestine for the absorption of other compounds ie. salts, sugars and amino acids. If we take in a lot of these compounds water must accompany them as a buffer in order for them to be absorbed. This is important when we look at things like sports drinks. These drinks often have high concentration of sugars and in some cases salt. This can be problematic for the rate of absorption of water. Athletes often complain of a feeling of fluid in the stomach after drinking large quantities of these drinks. That is exactly the case. Water must follow these compounds into the small intestine.

What this means is that water on its own is often absorbed faster than a sports drink. For short term exercise plain water is a better choice for rapid hydration. During longer bouts of exercise and in hot conditions many minerals and salts are lost from the body. The loss of minerals, salts and the consumption of glucose will have a significant impact on muscular and cognitive performance. In addition there is a change in osmotic gradients. This change may hinder the absorption of water. Drinking large amounts of plain water over long durations may cause potential hyponatremia (low sodium levels).

In many cases the advice given for monitoring hydration status involves examining the colour of our urine. Dark urine signifies dehydration. Lighter colored urine signifies good hydration. The concern here is that if one drinks lots of water without replacing salts and minerals, water will have problems being absorbed if salt levels are low. It can lead one into a false sense of being properly hydrated.

 

Hydration is critical to performance and must be a part of your routine.

An athlete must consider the circumstances. Short bouts of exercise, an hour long for example will not deplete salts and therefore plain water is a good choice. For bouts much longer and/or in heat, a marathon or long day hiking for example, a hydration formula is essential. By replacing salts and other compounds we can maintain a better level of hydration as well as providing essential compounds to cell function. In addition many compounds such as salt absorb better with sugars. A hydration formula should not just contain salt for this reason. Amino acids also help with salt absorption. If one uses a formula containing these other compounds they have the added benefit of replacing glucose for energy metabolism as well as reducing cell damage and aiding in recovery.

There are many commercially available sports drinks and formulas. Some are better than others. In many cases some popular brands are driven as much by taste as they are function. Many are too highly concentrated with sugar. In these cases they would be better if watered down. The level of solute concentration should reflect the conditions but in most cases weaker concentrations are less problematic. Less obvious, effective choices for hydration are targeted for a more clinical setting. Dioralyte and Pedialyte are specifically formulated for hydration without all the extras that you may find in some commercial sports drinks. One can also make a pretty decent homemade formula using natural ingredients. Water, salt and honey can form an excellent and simple hydration formula. Adding a little glutamine to the mix will also tick the box for amino acid presence.

 

Many great options but often designed for taste preference rather than hydration needs

A favorite of ours is the following. It has been tried and tested with excellent results.

1 litre of water

6 teaspoons of honey or maple syrup

½ teaspoon of table salt

 

In terms of timing it is important to constantly manage hydration. This means consuming fluids before, during and after exercise in accordance to the environment and type of exercise. Something to note is the effect of dehydration on digestion. Often athletes prioritize eating over rehydrating. In the case of multi day events this is not the best strategy. Poor hydration can lead to poor digestion and slow the process of refueling quite dramatically. Gastrointestinal stress can lead to poor sleep and other issues which have disastrous effect on performance. In the case of cutting weight for sport, water cutting is a popular method. An individual will purposely dehydration themselves in order to reduce overall bodyweight. After weighing in, if one does not rehydrate first it can be very difficult to consume food and digest properly before competition. Often a hydration formula and efficient hydration strategy will have greater benefits than eating after a weigh in. With that in mind hydration should always be priority number one. With added glucose it may also be a fast way to restore glycogen so it is beneficial in multiple ways.

Athletes need to be practical and efficient with every aspect of their performance that they can control. Hydration is extremely important but rarely discussed in practical terms. When one considers the circumstances and has some understanding of the process one can manage the situation much more effectively. That very much applies to hydration. A little bit of thought and practice with hydration strategies can make performance more consistent and training more effective.

Recovery Review: Cryospa!

I recently had the opportunity to have a session in a Cryospa. Cold therapy is nothing new. It is perhaps the most utilized method of recovery in one form or another. Ice baths and ice packs have been used for decades to treat minor and acute injury and help athletes recover from tough sessions. There are now much more advanced forms of cold therapy commercially available. We have many new tools such as cold compression/pump garments and cryospas. The cryospa is very much like an ice bath except it has integrated water jets. This allows for a steady flow of cold water around the body. In the past the water adjacent to the skin would warm up a little with body heat. While a very small factor, this has now been overcome. In addition these jets help add a massage effect into the mix.

First a little theory behind cold therapy. The main mechanism is thought to be vasoconstriction. In reaction to cold stimulus our body constricts blood vessels to reduce blood flow to cold regions of the body. It redirects blood flow through vasodilation back to the core to help maintain core body temperature by reducing the blood’s exposure to cooler temperature. Doing this is thought to help reduce swelling around injuries and also force metabolites in the blood produced from heavy exercise away from the muscle. It is also thought that once the cooled areas begin to warm blood flow is increased as constriction ceases. It is theorized that this returning blood from the body’s core and organs is oxygenated and carries a fresh supply of nutrients to help aid recovery. For this reason cold is often used in conjunction with heat which has the opposite effect of promoting bloodflow.

Cooling the body is thought to help switch the body from sympathetic to parasympathetic. In short it goes from fight mode to rest mode. This should help athletes to relax and sleep after exercise. It will also allow digestion to become more efficient helping refuel the body. This downregulation of the body’s nervous system can be very important in the recovery from exercise as this is when adaptation is most likely to occur.

Ice Baths are one of the most popular forms of recovery.

Ice Baths are one of the most popular forms of recovery.

While there are some solid theories and evidence behind the use of cold therapy there is also some conflicting research. Some argue that cold therapy may interfere with the body’s natural recovery mechanisms. This review will not become a critical analysis but it is important to note there is some valid disagreement in the literature.

In order to get the most out of the session I decided from my own knowledge and opinion that it was muscle soreness I wanted to examine. Soreness from training or delayed onset muscle soreness (DOMS) is extremely common in athletes. In the days prior to the session I decided I would try and induce as much DOMS as possible so I could see how the cryopsa helped reverse or reduce it. I did the things I know cause soreness for me and it was not a schedule I would recommend to anyone. It was designed purely to enduce soreness and not for any training benefit. My training looked like the following.

Day 1- Lower body strength training (Focus on Intensity)

            5X5 Heavy deadlift @85%approx with 2-3 minute rest

            3X 15 Split squat supersetted with Walking lunges with 1 minute rest

            3X Rounds of 5 reps Front squat @50%, 10 Jump squats, 15 bodyweight squats with 1min rest

Day 2- Sprint intervals

            10X 20m sprint walk return rest

            5X 200m with two minute rest

Day 3- 60minute TT cycle with hills.

I was sore after day one but day two and three really built upon that initial session. After the cycle on day 3 my legs felt dead and aching. I felt tight and my glutes and quads had definite soreness moving around. Range of motion was also quite poor due to the tightness. On the afternoon of Day 3 I had my session in the spa.

The spa itself can be filled with epsom salts and magnesium which are also thought to help increase rates of recovery. I was given little neoprene booties to keep my toes from going numb. The water temperature was 4°C. Stepping into the spa was pretty unpleasant as expected. I felt winded and wanted out. This died down after a minute. I was submerged up to waist level but it can also be done with only ankle and knee submersion or all the way up to the shoulders. The whole cycle lasted 10minutes with the jets on full blast. The jets definitely made it feel colder than a standard DIY ice bath.

The spa was pretty user friendly despite the initial shock getting in.

When I left the spa my legs were cold and a little numb. As the heat came back into them they definitely felt fresher than when I walked in. Over the course of the day as they heated back up I didn’t really notice any major soreness which was different to before I completed the session. It almost felt like the cycle session was removed from my week in terms of it’s after effects. The dull throb and deadness was gone from my legs and I felt a bit freer moving around. I did feel a little stiff still and there was still a bit of soreness but not quite as bad as before. I would love to have done some performance measure but there is plenty of literature out there and I wasn’t looking to do a full experiment. This was to satisfy my own thoughts and curiosity.

Legs were pretty numb leaving the spa but quickly warmed up.

Legs were pretty numb leaving the spa but quickly warmed up.

The bottom line is I have some doubts on cold therapy as with most things. In saying that I genuinely felt the spa session took an edge off my soreness. If I had full access I would definitely utilize it on a regular basis. This is a very subjective opinion but one cannot discredit the mental impact of recovery. If an athlete feels better and fresher regardless of their actual physiological recovery it is a major benefit.

Different things work for different people and there are tools and methods I simply find useless. The Cryospa is not one of those. I highly recommend trying it or something similar. See how you feel and if it works for you. A lot of being an experienced athlete is trial and error and simply learning your body. A certain amount of individual experimentation is necessary to do so.

I would like to thank Bodyright Physiotherapy (http://bodyrightphysio.ie) and Cet Cryospas (http://www.cetcryospas.com) for the opportunity to try something new. I hope some of those who read this may find my experience useful to them and encourage them to experiment with things for themselves.

Lifestyle for maximum performance.

This article comes by request from some of the athletes we work with. Often athletes are placed under quite stressful environments both physically and emotionally. Training volume, competition stress, exams and possibly work commitments all contribute to general stress levels. In order to get the best performance, an athlete must manage his lifestyle. In many cases stress is unavoidable and taking rest is not always possible. In order to maintain performance an athlete must manage his/her lifestyle in order to stay healthy and keep recovery effective.

Having lived with many athletes in many scenarios there is often a situation where there are multiple competitions in a very short timeframe. Whether it be qualifying heats, a tournament or just a heavy training block, recovery time could be very short. In these situations there are a number of things which must be considered as they can be quite detrimental.

Sleep

Adequate sleep is absolutely essential. There is no exact or perfect amount but we recommend 8-10 hours with 20 min naps during the day where possible. Early in a competition week less sleep may seem to have little negative impact. It will catch up with the athlete though, so discipline is essential to ensure it does not become an issue as days pass.

Nutrition

Nutrition is also essential during competition. Athletes cannot eat for enjoyment, they must eat for function during these periods. Ensure that there is adequate or even a surplus of both protein and carbohydrate. Carbohydrate provides fuel essential to exercise. Protein repairs cells and is essential for recovery. A calorie surplus is normally hard to achieve but it should be the goal during competition. It may also be a good time to include a broad spectrum multivitamin. The immune system is often taxed heavily and while a balanced diet should cover this, it is good to have the added back up. Clean whole foods are best. Keep things simple during this period; often athletes need to rely on restaurants during these periods and must ensure they do not get tempted.

Nutrition is key to having enough energy fortraining camps and competition.

Nutrition is key to having enough energy for training camps and competition.

Hydration is also very important. Even when urine is clear it does not necessarily mean you are hydrated. Investing in hydration tablets is a good way to ensure salts are replaced, ensuring fluids get absorbed as opposed to flushed through. This is particularly important in hot climates.

Alcohol

Even during competition some athletes still want to go out for a drink. Maybe to celebrate a pool stage win or just to relax. Whatever the reason one or two drinks will not have a huge impact. Having more than this however, will have a massive negative impact. Dehydration as well has glycogen replenishment both become an issue. Long nights cut down on sleep and standing all night in clubs or the bar all take a toll.

Activity

Sir Chris Hoy said “Never stand when you can sit, never sit when you can lie down”. This is a good way to think. Often athletes spend their rest days on their feet the whole day and it becomes counter productive. Listen to Sir Chris; it worked for him.

Maintenance

Stretching, foam rolling and massage on off days can be quite beneficial. In many cases tension in the muscles is reduced. This can relieve pain and help restore muscle function. It can greatly aid the recovery process.

Relax

When you do get a chance to rest it is important to relax. For some that means staying in front of the TV, for others it’s going sightseeing. Some people need to stay busy to distract themselves and that’s fine. The trick is to avoid overthinking and replacing physical stress with emotional stress.

Some of these seem very obvious but a group of guys on a competitive tour can often lose discipline. Similar to a phone battery when a competition or tour starts the battery is full and there is no concern for energy usage. As the battery gets low there is a mad panic to conserve energy. Inexperienced athletes fail to recognize these issues early enough and they learn the hard way. Sometimes they may also lack the discipline. Often lapses early in the week only take effect later in the week, so going by feel is not a wise approach. By supporting recovery via lifestyle we tend to experience less injury and sickness during a season. Better recovery leads to a healthier body. Chronic stress will eventually take effect. Some more injury prone athletes may need to look towards their lifestyle as a possible contributing factor. The best thing is to form a routine and stick to it regardless of situation. It’s the little slips in discipline that catch athletes out.

Recovery Tools: Active Recovery!

Recovery has become a core factor in every athlete’s training and success. There are many recovery methods which can be employed all targeting different things. Not all methods work well for everyone and people will have their favourite. This is normal as the processes of each method are slightly different. Some things will simply have a better effect on certain individuals than others. One popular and convenient method is active recovery. In terms of effect it appears to be relatively beneficial to everyone.

When we exercise we produce metabolic by-products. These by-products can interfere with muscle contractions and contribute to fatigue. While we exercise we have a system to clear these by-products and consume them. When we stop, the rate of clearance reduces and they can be left to accumulate. Eventually they will be cleared up but at a reduced rate. Some gentle exercise post training can help ensure these metabolites are cleared effectively.

When we do more intense muscle contractions where a lot of force is applied, muscle stiffness can occur. Stiffness is when the fibres fail to fully relax causing a temporary shortening of muscle fibre length. Gentle movement can help break up this tension and reduce stiffness. Active recovery can be quite effective in doing this. The submaximal contractions allow the fibres to relax back to resting tension.

Another mechanism it can influence relates to bloodflow and temperature. In order to repair damaged muscle cells after intense exercise they need a good supply of nutrients. This supply comes from the blood. Increasing bloodflow to tired muscles ensures they get a good supply. In addition increasing local muscle temperature can help the muscle fibres loosen up and restore contractile function. Gentle exercise activates the muscle pump which flushes blood through the muscle as it contracts and relaxes.

These three mechanisms have some quite favorable benefits on getting back to top performance in a short period of time. An important factor and one which many people get wrong is when and how to do active recovery. Active recovery first and foremost should not contribute further to fatigue. Intense exercise is not recovery; it is simply another session. Often people perform hard conditioning instead of resistance training believing it promotes recovery. While some aspects may have a similar effect, the benefits are cancelled out by the increased metabolic and cell stress. A reliable intensity to work at is 50-60% of Heart rate reserve. The session need not be any longer than 30mins to be effective. We recommend low load bearing exercise to reduce any further stress on joints etc. Swimming, crosstrainer and biking are excellent choices.

Deciding when to employ active recovery is also tricky. In most cases we should employ some sort of short active recovery in our warm down procedure. This allows us to clear metabolites immediately after a session as well as stabilizing core temperature in a more gradual manner. Some like to use recovery sessions on their day off. In this case promoting bloodflow and reducing stiffness are the main mechanisms. This scenario is problematic as one must refrain from turning recovery into more conditioning work. While for some, running and rowing may be suitable, many heavier athletes will actually induce more fatigue and joint stress using these exercises. A 5k run is not a recovery session it is aerobic training, while less intense it simply applies a different type of stress.

It is important for athletes to understand the purpose of active recovery and the mechanism by which it works. Just because a session is of lower intensity it does not automatically become recovery work. The sole purpose of active recovery is to promote a restoration to a rested state and therefore maximum performance potential. It has a clear purpose and application. Smart athletes recognize the difference and they reap the rewards of using it effectively.

Sleep and Competition

This post comes in response to a question we received from a reader. “Why is getting a good night sleep important before competition?”

Sleep is restorative and not preparatory in terms of physiological function. When we sleep there is a down regulation of the Sympathetic Nervous System (SNS). This is our “Fight mode” which reacts to stress and allows us to “Perform”. The opposite is the Parasympathetic Nervous System (PNS). This is our “Rest Mode”. It allows the organs to dial back on activity and gives them a chance to recover fully. When in rest mode the immune system is highly active. Time and energy goes into repairing damaged tissues and resupplying fuel stores. If we were constantly in fight mode the body would eventually break down and the safety stops would be activated. Our immune system would also become depressed and we would become more susceptible to infections and illness.

Studies examining the physiological response to impaired or reduced sleep prior to competition have shown no significant negative impact. It does not have a direct impact on physiological capacity or function. However, mental and cognitive function are significantly reduced. This on its own will cause noticeable decrements in performance. In terms of an athletes mood state there will be a drastic decline in motivation depending on the individual. Their ability to push themselves mentally and stay alert will be reduced.It is also important to note that we are discussing lack of sleep rather than a night on the town. The later has many other factors added to the mix which can cause issues.

When an an athlete may be competing or training for multiple consecutive days, sleep plays a restorative role. It becomes a major part of the bodies natural recovery system. Disturbed or impaired sleep my hinder the restorative processes that have been mentioned from taking place. The ability of an athlete to recover is vital in maintaining performance when there are multiple days of activity.

From a practical perspective, an athlete should always try to get adequate sleep. The optimal amount will vary from one individual to another. If an athlete misses sleep before the competition has started they should place their focus on mental preparation and motivation as this will be the site for concern. After the race they should look to get sleep for both mental and physiological benefits. Inadequate sleep will result in poor recovery which will likely result in a drop in performance on consecutive competition days.

Athletes should make note of what is normal for them and what lets them perform at their best. Having a record of sleep is a good tool to allow an athlete identify when there might be an issue. This can be useful in the grand scheme as certain trends in sleep patterns can be identified and managed. Many athletes suffer from sleep disturbances as a result of nutrition, travel, stress and a wide range of factors which can be managed.

In conclusion, a lack of sleep before a big competition is not ideal preparation for an athlete. It is not always avoidable and so it is important for them to understand how it might effect them. It is a factor which should be monitored and managed as part of an athletes routine.

Recovery tools: Compression Garments!

Recovery is one of the most important factors when it comes to human performance. There are many recovery methods available all dealing with certain physiological mechanisms. In this post I will discuss the use of compression garments and how they seek to increase recovery rate.

The use of compression garments has, become quite popular recently and there are several brands providing many different options. The basic theory upon which they work is quite simple. When we contract our muscles, the fibers squeeze against the surrounding blood vessels. When we relax these vessels are released. This natural process can aid circulation as it helps promote blood flow through the vasculature. This is particularly beneficial to the lower limbs, where the blood pumped back towards the heart must compete with gravity. This return flow is known as “venous return”. It takes blood that has been deoxygenated by the muscles back to the lungs for re-oxygenation. It then returns to the heart which pumps it back around to the muscles again.

Compression garments provide external pressure on the limbs, artificially causing a similar compression on the blood vessels. This extra compression helps venous return in the same way contracting muscles do. When we exercise we increase the rate at which the blood becomes deoxygenated and must in return, increase the rate of re-oxygenation. In this case compression garments can potentially be beneficial during exercise by promoting circulation. They have a number of other benefits during exercise but I shall focus on the recovery aspect for now.

When we are exercising our muscles produce a large amount of metabolites. These metabolites will eventually break down and dissipate with some rest. The issue is that when we stop exercising we generally rest in a fairly stationary position. Sitting stationary these metabolites do not clear as well and can accumulate in the extremities. Having compression garments may provide the improvement to venous return without having to do much physically. This is where compression garments could have their greatest influence on recovery rate as they can work will the athlete rests.

Compression garments can also help prevent and reduce swelling. During intense exercise we can cause damage to cells which leak fluid into the surrounding tissue. This produces swelling. In most cases swelling can be considered part of the healing process. It can also cause a sense of tightness and discomfort. In this case, extra compression may prevent excessive swelling and tightness during competition and training days.

In terms of performance, research on compression garments is still largely inconclusive. There’s a fairly simple reason for mixed results. For garments to work they must provide adequate compression. Owing to the fact that we are all sized a bit differently, generic sizings for garments may not work for everybody. Anecdotal evidence suggests different brands work better for different people based on individual fitting etc. Despite this we recommend their use as its another tool in an athletes arsenal. They can be useful during activity, at rest, and during travel.

Such garments will not turn a weekend warrior into an Olympian overnight. They can however, when used in part of a larger scale strategy, allow an athlete to recover at a slightly faster rate. When dealing with recovery it is important to try be as thorough as possible as it is a factor that is largely controllable.

Training day or night!

This post comes in response to a question we had from one of our readers. He asked “Why can I lift more when I train in the evening, as opposed to early morning training?” First of all, everyone is a little different in terms of what works for them and what they prefer. There is not always a wrong or right when it comes to training. Often the answer lies between what works and what allows you to be consistent. However, there may be some physiological reasons which could answer why someone may perform better later in the day than in the morning. Circadian rhythms which are often overlooked when it comes to health and performance science but they are very real. These are natural rhythms of life which we constantly are subject to. The seasons and solar cycle are two such examples which have a direct impact on our lifestyle and health. Our body has a natural flow of hormones and neurotransmitters which are directly influenced by our environment. When we sleep our body goes into standby mode allowing us to rest and recover. When we awake there is a cascade of hormones and neurotransmitters that prepare us to go about our daily business.

This all starts with the suprachiasmatic nucleus (SCN) located within the hypothalmus a very active part of the brain, which is essentially the control centre for our endocrine system. The SCN is stimulated by sunlight through our eyes and triggers our start up switch on a daily basis. Other hormones such as cortisol, testosterone, and human growth hormone follow similar patterns stimulated and regulated by a number of other factors. The timing and magnitude of these chemical patterns will vary slightly from one individual to another. These rhythms can therefore dictate when we are primed for certain actions. One of these rhythms is our body temperature. We tend on a consistent basis to have a daily peak in the afternoon. This is provided we do not influence it through exercise etc. Increased body temperature optimises muscle contractile function and a range of other things that can improve our strength performance.

In addition to these natural rhythms we have lifestyle influences. We know that there are nutritional differences from morning to evening. When we wake, we are in a fasted state and usually the complete opposite in the evening. The ingestion of certain food types can dramatically alter mood state and energy levels. We also have decreased flexibility as a result of lying relatively stationary for a long period. Sleep inertia is also an influence. This is that sleepy, clumsy mood you feel when you awake in the morning and it takes time to recover from. These are all factors which not only impact performance but also mood and motivational state. These exclusive of other factors, can be significant.

Some people are relatively unaffected by these things, while others may feel them dramatically. We are creatures of habit and sometimes we simply become used to doing things in a certain way. When we break routine our mood can reflect it. Regardless of these factors an individual may feel more prepared to train in the morning and see no real difference to training in the evening. It all comes down to the individual. In terms of management of an athletes performance we should consider this issue and take it into consideration for planning. Training should ideally be scheduled at approximately the same time of day as competition. Over time the athlete will learn to manage themselves in such a way that they can perform optimally come competition time.

I hope I managed to answer the question sufficiently!
