HARDEN YOUR HEALTH

The last few weeks has seen global efforts to thwart COVID-19 the latest Corona virus strain which is creating momentum worldwide with escalating infection rates. Over the last few days we as athletes have also seen the postponement and cancellation of some major sporting events which as hard a pill as it is to swallow , but its definitely the correct course of action to reduce high a infection risk. Plenty of training and racing goals have been thrown a curve ball and these goal posts have had to be shifted. Personally right now I feel the focus should be on our health and ensuring we are not just responsible for ourselves but for those around us.

The training for us all should continue as we do not just do this for finish line medals and kudos. For most of us it’s a lifestyle and yes racing motivates us to train. However right now we have a much more important motivating factor which should keep us on our toes and that my friends is health. As we stand without a treatment for this virus our only course of action is to boost our own immune systems and make sure that we are in excellent condition to be able to fight off any infection that comes our way.

Training and racing especially as intensity and volumes increase so does immune system suppression which makes us far more susceptible to infection and illness. In line with a real war we are just about to face, I decided to put together a short guide of how we as athletes can strengthen our health and boost our immune systems to be able to navigate this next part of our journey.

WHAT IS YOUR CURRENT HEALTH STATUS
Starting with the basics, it’s always best to get a proper snapshot of your health first. How can you hope to strengthen your immune system if you have an underlying condition? In my line of work I come across many athletes with underlying conditions such as anaemia, insufficient vitamin levels, improper organ function or underlying infections and inflammation. If you have an underlying condition and do not know about it then you basically starting on the back foot and this needs to be addressed first.

What should you do?
A full medical with a nice batch of basic bloods & some additional vitamin and mineral testing to make sure everything is in good order. Remember as an athlete you place your body under stress and if certain levels are on the low end its highly likely that you will reduce them further and impact your health. Vitamin drips in my view are a complete waste of time without understanding exactly what you are treating. There is something called excessive vitamin and mineral dosing and in some cases this can be highly toxic to the body. My advice is to see a medical professional and get it done properly without playing a guessing game. I wrote in a previous blog called Blood’s don’t Lie you can check it out by clicking here.

LISTEN TO YOUR MESSAGES
Once you get the results from your physician its best to discuss them with him or her and make sure everything is in line. Remember you are an athlete not a couch potato. So make sure the physician understands that because some might say your levels are normal. However that is the general population norm. You want to rather be on the upper end of the spectrum not on the lower end due to the amount of stress the body goes through daily. If you do have an underlying condition you have to address it. Athletes are so good at ignoring issues when it comes to injury and illness. Don’t ignore them and adhere to proper medical advice.

NUTRITION
Proper nutrition is absolutely the health fuel for your engine. Healthy nutrition allows the body to fortify and strengthen itself against illness and disease as well as ensure our energy system is kept up at all times. When we make bad food choices we place additional stresses on the body and in times of need when we should be our strongest to fight off foreign invaders this should be kept to a bare minimum. After all our own natural defences are all we have and we need to make sure that they are fortified. Eat nutrient dense meals with plenty of vegetables and fruit and ensure that you are eating properly for your unique needs. As an athlete ensure your calorie intake is not an excessive deficit so that the body gets sufficient nutrients to help with restoration and repair. Carbohydrates often get a bad rap however when it comes down to endurance sport carbohydrates are your fuel king and when it comes to recovery there is nothing that will get your fuel tank recovered quicker than carbs. Remember carbohydrates can come in healthy forms such as fruits and vegetables which are high in anti-oxidants and free radical fighting nutrients. Eat with intent and insure that whatever goes into your mouth has a purpose for strengthening your body.

TRAINING
It’s a scientific fact that exercise boosts the body’s ability to fight off infection and illness. However, one should not over do it. Endurance athletes tend to place huge stresses on the body with intense bouts of volume training. This will certainly place the immune system at risk. Over-training places any athlete at risk to infection. Rather stagger your sessions properly, reduce intensity ratios and volumes and allow the body to fortify itself without over stressing it. With most events now cancelled or postponed do yourself a favour and switch your focus to health especially in these trying times. Get outdoors more and limit your visits to the gyms in order to protect yourself more from infection risk. Most importantly just keep on going.

SUPPLEMENTATION
Alongside a healthy eating regime supplementation can play a beneficial role. I mentioned earlier blood tests can show where there are areas of deficiency and those can be addressed. Right now though our focus is on immune system strengthening and there are a number of supplements which have been shown to aid immunity.

Vitamin C
Its amazing how Vitamin C is at the top of most people’s lists when it comes to immune boosting. However it is not really the king on the list. It is an antioxidant which helps fortify and reduce inflammation however its over estimated by a large amount due to massive ongoing marketing in the supplements sector.

Vitamin D
If someone asks me what to take for immune system strength I will always advocate vitamin D as one of the best immune system defences. Vitamin D can improve immune system responses and a deficiency in vitamin D is associated with increased susceptibility to infection. Research suggests that vitamin D can help reduce the risk of respiratory infections, including colds and flu especially among people who don’t get enough of the vitamin from diet or exposure to sunlight which is most of the population. Athletes tend to train in the early morning hours and many also indoors which limits exposure to sunlight and then again sun creams further limit the body from it. It is worth dosing with vitamin D and a simple blood test.

Wellmune®
This is something you have probably never heard of but it is the bomb. Wellmune®  is a leading natural yeast beta glucan clinically proven to help strengthen your immune system. In a clinical study, marathoners taking Wellmune® for four weeks experienced a 40% reduction in upper respiratory tract infection symptoms. Wellmune® primes immune cells helping them find and kill foreign invaders.Where can you get this ingredient. 32Gi’s new plant based pure protein being launched this week contains the correct dosage of Wellmune® to ensure your immune system is properly fortified. A medically backed natural supplement is absolutely worth taking.

32Gi’s NEW Immune Boosting Pure Protein

Zinc
I think zinc is an awesome mineral . It does help the immune system fight off invading bacteria and viruses and worth dosing to keep immunity up nicely as well as it being good for the skin.

Elderberry
Elderberry is packed with antioxidants and vitamins that may boost your immune system. It can aid the reduction of inflammation, lower stress levels and help protect the heart. It is often advocated in the prevention and ease of cold and flu symptoms.

Probiotics
Probiotics are there to keep the gut healthy and to ensure the immune system functions well. Taken from a peer reviewed research publication it states that probiotics can also modulate the immune system, enhancing the body’s innate immunity. This modulating effect helps alleviate excessive inflammation in the gut, thereby boosting immune function. We know that health gut bacteria is important for proper health and immune system function and there is no harm in dosing with probiotics on a daily basis.

In short there are many avenues we can try to help fortify and improve our immune system function and health. Not all vitamins and minerals have been researched to such an extent that they are conclusively providing the best benefit. We are after all unique and what works for one individual may not work for another. One thing we do know and that is proven, is that proper healthy nutrition, plenty of good sleep and exercise goes a long way to ensure that our body’s remain physically strong and healthy to weather the storms.

ARE YOU FUELLING TO FAIL?

The world of sports nutrition is quite an interesting space to be in. I often get to hear sob stories of failed races due stomach issues, lack of energy, severe cramping and nausea. Just this past week I stood at the 32Gi Sports Nutrition and Dis-Chem expo stands at the Cape Town Cycle Tour advising athletes on fuelling strategies based on their needs. The common theme I got from the few days there was that most athletes create very interesting meals but they have absolutely no idea how to cook. If you are going to make a chicken soup then why add lamb, beef and fish to it?

When it comes down to proper fuelling it needs to be a well thought out simple recipe of success. Complicating fuelling will only lead to issues whether rebound hypoglycemia, gastrointestinal distress, fatigue, nausea dehydration and a complete lack of energy.

Sports Nutrition products are designed to be a convenient fuelling source which meets a specific need. The carbohydrate blends, mineral levels and recommended volumes of consumption are calculated and designed to have a desired function. The minute you take that product and start to add other nutrients and blends into the mix there is absolutely no ways the desired effect will take place as you are changing the recipe for the successful pot of soup.

As an example 32Gi’s new Race Pro drink is designed so it can be a single bottle energy source feed for an entire event. I had an athlete tell me he tried it and along with the drink he consumed gels and nougat bars. He said the drink did not sit well with him and he felt terrible. I asked why he did that and his response was because he needed them.
Of course he would feel terrible. Here he is drinking a product that has a much higher gastric emptying rate than a gel and its designed to be used in a certain way for a desired effect, yet he throws a gel and nougat bar into the mix. That is just plain stupid and to explain it to him in simple terms I asked him if he likes peanut butter sandwiches? He said yes. So I told him the next time he makes a peanut butter sandwich add some broccoli and cauliflower with it between the two slices of bread and if he really wants it to taste great and make him feel better he should add some egg and chocolate to it. He looked at me and said you kidding right?
I said no not at all it seems you the kind of person that enjoys this mix. The point I was making was that this is exactly what he did with his fuelling. He concocted an unscientific complicated recipe for disaster which led to his fuelling failure.

When it comes to proper fuelling you need to make sure you know exactly what you are taking in, how much you are taking in and when you should be taking it.

So how do I develop a proper fuelling strategy?
Firstly you need to separate your energy and hydration requirements.
Energy requirements are unique to an individual and each person will have to figure out what works best for them. Energy required in endurance events comes mainly in the form of carbohydrates and protein. Short hard events 3 hours or under would not need protein intake but mainly carbohydrate intake to fuel the level of effort. As the duration of exercise increases carbohydrates together with a small portion of protein would play a bigger benefit in sparing glycogen and slowing amino acid breakdown due to gluconeogenisis which can lead to muscle fatigue.

Step 1: Determine the Energy Requirements
In terms of sports nutrition it’s important to understand that a balance between energy and digestive comfort is required. What you consume needs to be processed and each person is unique in how adaptive the digestive system is based on genetics and diet.
It’s best to start with the type of discipline you are wanting to do. Cycling provides more stability to the digestive system so generally a higher dosage of fuel can be tolerated. Running however generates a lot more sensitivity around the digestive system and smaller feeds are generally tolerated a lot better. Lower intensity exercise as well as lighter athletes can look at a lower carbohydrate intake while higher intensity exercise and heavier athletes will look at a much higher carbohydrate intake to support the efforts. This can range from 0.8g/kg bodyweight up to 1.5g/kg body weight per an hour. General Guidelines look at a protocol of 30g-60g of carbohydrates per an hour which equates to 120Kcals – 240kcals per an hour. Only in very specific carbohydrate blends can higher dosages be tolerated to support long duration exercise but this is not recommended without proper testing in training first.
The below chart is an approximate guideline of how you can approach your fuelling strategy but make sure to test it in training. Always start low and then build higher to ensure comfort and digestive system adaption.

SportWeight Hourly Carbohydrate / Protein Dosage
Running50-60kg30 – 50g (120 – 200Kcals)
Low GI Distress Risk
 60-70kg30 – 60g (120 – 240Kcals)
Low GI Distress Risk
 70-80kg30 – 65g (160kcals-260Kcals)
Medium GI distress Risk
 80kg >40 -70g (160Kcals -280Kcals)
Medium GI distress Risk
Cycling 50-60kg30 – 60g (120 – 240Kcals)
Low GI Distress Risk
 60-70kg40 – 70g (160 – 280Kcals)
Medium GI distress Risk
 70-80kg50 – 80g (200kcals -320Kcals)
Higher GI Distress Risk
 80kg >50 -90g (200Kcals -360Kcals)
High GI Distress Risk

Start with the lower volume zones and gradually increase the dosage in training to see what the best balance is of energy to digestive comfort. If the digestive system takes strain with higher dosages, then lower them. That is your tipping point. It’s best to consume in a drip feeding manner meaning more frequent feeds to get the desired amount. This reduces the risk of the digestive system going into distress as it’s easier to process smaller amounts at once. It also stabilises you better over time mitigating the roller coaster effect of highs and lows.

As mentioned above the fuel needs to support the effort. This is based on time and intensity. If we take a look at the basic training zones from zone 1 to zone 5 we know that lower intensity efforts will require a lower carbohydrate intake to support it as the body will have the ability to maximize fat usage as a source of fuel. However as we move through the zones which can also happen over time due to cardiac drift the carbohydrate volume will need to increase to support the efforts. As an simple example a slow Zone 1/2 ride of 2-3hrs will not need much carbohydrate support so in the case of a product recommendation 32Gi Endure and or 32Gi Hydrate electrolyte fizzies would be able to support this session. But take a hard quality session of say 90min to 2hrs with hitting Zone’s 3 – 5 where glycogen becomes the main fuel source then a higher dosage of carbohydrate intake is required to support that effort. To truly meet training adaptations meaning supporting your full potential properly when doing quality workouts it is important to fuel that effort properly. In this case a drink like 32Gi Race Pro, Race and 32Gi Gels would provide better fuelling support. I created a video a while back explaining the fuel tanks relative to zone training. It is worth a watch just Click Here to view.

Step 2: Choose your Energy Source to Meet your Fuelling Requirements
What format of fuel are you wanting to use to achieve your energy requirements. Do you prefer a liquid feed or a solid feed or do you prefer a combination of both?
The most important thing to remember is that you need to adhere to simplicity and a proper measured value to ensure you get exactly what you need as well as the correct absorption rates. Check the ingredients carefully you want it to be as clean and simple as possible. After all your stomach needs to process what you putting into it. Keep it carbohydrate dominant and very clean avoid fats they slow down the rate of absorption and especially avoid trans fats you only asking for trouble by mixing that into you fuelling strategy.

As a simple example if you are going with a concentrated energy feed like 32Gi Race Pro that will provide you with all your energy requirements in a single bottle then there is no need to take anything else with it. Its specifically designed to be absorbed at a certain rate in its current format and mixing it with another product will impact that. So the only thing required along side it would be a hydration drink such as 32Gi Hydrate or water. If you are wanting to use say an isotonic drink such as 32Gi Endure you need to have in mind that a bottle contains 44 grams of carbohydrates per a serving and if you drank 3/4 of that bottle in an hour you would only get around 33grams of carbohydrates per an hour which could be a serious energy deficit if you are aiming for a 60gram per an hour feed. So now you need to consider an external energy source which can be used with Endure which wont impact its efficacy but give you the required energy outcome. In this case adding in Chews or Gels would plug the gap in required hourly carbohydrate intake.

Step 3: How to Hydrate Properly
Once you have chosen your energy source you need to think about hydration very carefully. If you are using an isotonic drink which is providing you both energy and minerals to hydrate then you need to make sure that you will be able to take in the desired amount hourly to meet your hydration and energy needs. One of the reasons I advocate separating energy and hydration is because of weather conditions. On a hot day it will probably be easier to consume a bottle of an isotonic solution, however over consuming would mean knowing how many carbs you are taking externally to that and adjusting the feed accordingly. But what if its a cooler day? You don’t lose as much fluid in the form of sweat and you drink less fluid. However now your energy system is impacted by the calorie deficit and you need to adjust the feed accordingly. This might leave you consuming more energy in the form of gels which if not combined with the correct amounts of fluid can leave you with GI distress. The simplest feed is the easiest feed that does not require mathematical calculations during a session. In this case a single source feed and a single source hydration system are in my mind the simplest solution. From a hydration perspective you need to understand the conditions you will be exercising in and hydrate accordingly. Meaning the type of hydration drink will need to be determined according to the your sweat rate under various conditions. The idea is to try to replenish 80% of lost fluid. Water on its own is not as easily absorbed as a hypotonic drink and this is why I advocate a hypotonic solution to maximise fluid absorption and not take a chance. I wrote a blog Simply Hydrate explaining hydration in detail you can click here to take a read.

In summary I want you to understand that nutrition and proper fuelling are so critical not just in sports performance but also recovery and overall health. Many athletes focus on the training and wake up way too late to give the nutrition the proper focus it needs to perform, recover faster and remain in good health. Don’t be the athlete that spoils the soup and fuels your race to failure. Plan it properly, test it over and over in training, tweak it, bank it and take it to race day.

All the best

INTERMITTENT FASTING & THE ENDURANCE ATHLETE

Intermittent fasting has certainly come to the forefront over the past few years and more and more I am getting asked by endurance athletes whether I think intermittent fasting is a good idea?

The question I throw back in return is why do you want to do intermittent fasting? Mostly I hear endurance athletes telling me that they want to lose weight, lean out or become more fat efficient athletes. I guess the big question is what is your actual goal? Are you trying to lose weight? Are you trying to improve your previous best marathon or Ironman time or are you just doing it for health reasons.

Firstly intermittent fasting is a form of calorie restriction, correct? So if you can restrict calories by fasting then why can’t you restrict calories by eating correctly?
When you place your body into a fasted state you begin playing with hormones specifically leptin and ghrelin. The inability to balance these hormones properly due to either over eating or fasting can cause roller coaster effects which in the end do not land up serving the correct purpose.

The main question though is as an endurance athlete why would you even consider fasting?

Weight loss comes from eating correctly meaning a calorie restricted diet and proper macronutrient intake to support you unique requirements. This could be fat loss, muscle gain or maintenance. However as an endurance athlete what about energy, immunity, recovery and performance. Intermittent fasting will not support that at all. Actually quite the opposite it will hamper the recovery process, limit your energy levels and place your immune system under stress.

Let me further explain so that you fully understand the consequences of intermittent fasting while trying to be the best possible healthy endurance athlete.

RECOVERY
When it comes to recovery there are three main aspects that I look at and these are:

Rehydration
Muscle Protein Synthesis
Glycogen Restoration and blood sugar stabilization

If an athlete does intermittent fasting then rehydration and adequate fluid intake will not be an issue. The main issues will arise when it comes to muscle protein synthesis and glycogen replenishment. Adequate protein intake for an endurance athlete is important for recovery. Generally I work on around 1.4g – 1.7g of protein per a kilogram of body weight. This will depend on the athletes goals and training. Strength work and developing more lean muscle will require a higher protein intake while maintenance and repair will be on the lower side. Take a 70kg athlete who is training on average 90min a day. His required protein intake would be around 100-120g of protein per a day. This is in animal nutrition terms 4-5 chicken breasts or plant terms 2-3 cups of raw chickpeas. That is quite a lot of food. If the fasting window is quite long it means squeezing this protein intake into a small amount of time. However as we well know when it comes down to protein the human body is only capable of processing and absorbing a certain amount of protein every +-3hrs. This is generally in the region of +- 8-10 grams per hour. So its not possible to squash large protein portions into less meals and expect the correct portion amount for proper muscle protein synthesis to take place. Actually the opposite over eating protein ultimately causes a rise in blood sugar and that can easily lead to weight gain. We also know that consuming a protein with a carbohydrate post exercise up-regulates amino acid uptake specifically leucine which is a trigger for muscle protein synthesis.

What also allows for proper muscle protein synthesis is a positive nitrogen balance. Nitrogen is the most crucial component of amino acids, which are the building blocks of protein. What this means is that if you are fasting the amount of nitrogen excreted from the body is greater than the amount of nitrogen ingested and there is no repair work taking place actually the opposite. So you are actually not recovering and triggering decent training adaptations.

EATING FOR ENERGY
The next aspect I want to look at is the energy system our primary fuel tanks being glycogen and fat. Glycogen is our rocket fuel and used at higher intensities while in lower aerobic zones fat becomes the fuel of choice.
A hard workout where glycogen depletion takes place will require carbohydrate intake post exercise to rapidly start the glycogen replenishment process and stabilise blood sugar. Extending the fasted period a few hours post exercise will delay this from happening and can lead to fatigue. This will also hamper back to back sessions. Then when it does become time to break the fast how do you know how much to consume in the form of carbohydrates and protein. If you do not ensure proper glycogen replenishment and stabilisation without triggering a roller coaster ride you will generate the the opposite effect from fat burn to fat gain by overeating.

When it comes down to the main energy system, carbohydrates are without a doubt our rocket fuel. If you are going to be doing an FTP (Functional Threshold Power) test or an interval or track session. Then how can you expect to achieve the best possible numbers without fuelling the session properly. Being able to push those sessions to the best possible effort is what ultimately will lead to better gains, as well as more fat burning post exercise by elevating the metabolic rate that much more. It has been scientifically proven many times over that a fuelled session will give better performance numbers.

When it boils down to performance gains and being a fitter faster and stronger athlete then you need to fuel your effort.
Fuelling during an exercise session or eating post exercise recovery meals is not the reason endurance athletes are overweight. Weight gain comes with overeating and inadequate macronutrient meal blends.

The Fat Efficient Athlete
In order to become a fat efficient athlete intermittent fasting is not required. Fasted training is a good way of developing this, but that is completely different from intermittent fasting. A fasted session does require a recovery meal post exercise and the volume and type of meal will be determined by the duration and intensity of the exercise session. Failing to recover from an exercise session is without a doubt failing the session itself.

To summarise my views on intermittent fasting and endurance sport. They do not go hand in hand. Endurance sport replaces a large amount of physical stress on the body. This impacts the musculoskeletal system, the immune system and energy system. The athletes body requires nutrients to fuel, repair and fortify it constantly. Failing to give the body what it needs will ultimately lead to a lack of performance and potentially illness and injury.
If you want to perform, lean out and get your own resilient Lamborghini engine and body then learn how to eat properly and avoid short cuts which don’t benefit that goal. If you are only trying to lose weight or have a medical condition which requires a calorie restricted diet then intermittent fasting can play a roll. However if you are an athlete intent on being the best version of yourself then get your nutrition right and stop playing games.

ENDURANCE VS ALCOHOL

Over the years I have had the good fortune of engaging with endurance athletes constantly. The talks I give around endurance health and sports nutrition always come up with a common question surrounding alcohol consumption. I am not going to sugar coat my answer, I say it as it is and in this blog I will spell out the good, bad and ugly around the issues associated with alcohol consumption and endurance sport.

Firstly we know from medical research that frequent consumption of alcohol can increase the risk of mortality and this should not come as a surprise to anyone. Men can tolerate a higher intake than women so relatively speaking women have a higher mortality rate for equal consumption volume than men. This does not mean the male population should go out and start racking up a large amount either because a small unit amount is the cut off before the mortality risk begins to rise and it seems men are far worse for wear as far as the stats go. Globally a large percentage of deaths are directly associated with alcohol consumption and one of the latest research reports on the global burden of disease study in the medical journal The Lancet states the following

“Our results show that the safest level of drinking is none. This level is in conflict with most health guidelines, which espouse health benefits associated with consuming up to two drinks per day. Alcohol use contributes to health loss from many causes and exacts its toll across the lifespan, particularly among men. Policies that focus on reducing population-level consumption will be most effective in reducing the health loss from alcohol use”. The full publication can be read here.

However alcohol or no alcohol my focus in this blog is around the impact of alcohol in endurance sport.

So let’s begin with the fact that it is the pleasure of most athletes to enjoy a beer or plenty more after the finish line of a race. When I raced overseas in Germany which is a big beer drinking nation I also had the pleasure of being offered a beer at the finish line however it was an alcohol free beer, which of course would not have had any negative impact on my recovery. However the alcohol certainly will.

Let us have a look at my major topics of recovery and see how in each case what the impact is.

Hydration 
Athletes finish training sessions or races in a dehydrated state. First step of recovery is to rehydrate properly.
Alcohol however is a diuretic. Basically this means what you take in will not aid hydration but hamper it and cause more fluid loss. Failing to hydrate properly post event will leave you feeling terrible the day after and the delayed onset of muscle soreness will be in an exaggerated state.

Glycogen Replenishment
One of the human body’s most important fuel tanks is the glycogen tank. A major source of energy supply and certainly a main contributor to fuelling the energy system during exercise and especially racing. Glycogen of course is primarily stored in the form of water, so failing to hydrate properly post session will definitely mitigate the proper replenishment of glycogen stores. In actual fact alcohol will definitely inhibit the re-synthesis of liver glycogen  and research has shown that it can take nearly twice as long to replenish the glycogen stores in an athlete that has consumed alcohol in comparison to an athlete that has not. This means if you are in the middle of peak training or back to back racing you can rest assured this will impact you significantly. Over and above this I often get told beer and wine is an excellent source of carbohydrates. You joking right? It is absolutely not a good carbohydrate source required to replenish glycogen.

Muscle Protein Synthesis (MPS)
An important part of recovery post exercise is of course muscle tissue repair. This requires proper nutrition meaning the building blocks of muscle being in the form or branch chain amino acids to be able to properly do their job. Some research has demonstrated that consuming alcohol post-exercise can suppress anabolic responses in muscles which means failure to repair properly and of course this prevents progress in the form of gains from exercise sessions. So yes this means your beer in one hand and steak in the other won’t cut it, your process is flawed.

Rest
The best way to recover post exercise of course is rest. I often stress one of the window periods of recovery is the sleep window and protein consumption prior to sleep can be of major benefit in enabling proper restoration and repair to the body. That is of course assuming you do sleep. However alcohol consumption interferes with proper sleep and completely removes the benefit of proper rest to recover between sessions.

Inflammation Reduction
Post exercise niggles often occur especially in field sport and areas of the body are often in an inflamed state which means that sometimes a reduction in inflammation is required. The sporting teams I work with use many types of methods to try to reduce inflammation post exercise one being an ice bath. However the problem is alcohol is a vasodilator which means it allows a rush of blood to the areas completely contradicting the treatment to reduce inflammation. This explains quite clearly that if you are injured and consuming alcohol it will slow down that healing process.

The Mental Game
Its a fact that endurance performance is very much mind driven. The ability to perform at a high level comes with complete focus and determination. Alcohol of course removes the ability to focus properly as well impairs co-ordination which can lead to the risk of irregular plane movement increasing the risk of injury.

Now that you understand the benefits of alcohol consumption in endurance sport its quite easy to decide how to use it to your advantage. Oh wait a minute I did not give you any benefits ;-).

Ok, lets be clear alcohol is not the best for sports performance and yes I am sure you will tell me many stories of athletes who performed under the influence of alcohol and it is their go to fuel and recovery meal. On the other hand I can assure you the stats are not in their favour from a health perspective and their later years will most likely see issues arising. I will admit though that alcohol does have a very large part to play in social circles and get togethers where people will relax, smile, laugh and interact. Of course happiness and stress relief is an important part of life and can offer longevity.

My advice as an athlete is to limit your intake significantly. Once in a while enjoy a glass of wine or a beer. Keep it as far away from long or quality sessions as possible and absolutely keep it out of race week. Most importantly ensure for every unit of alcohol you consume you take in a much larger amount of fluid to counteract the dehydrating effects.

Moderation is key and health always comes first.

COMRADES MARATHON – THE FINAL DAYS – The Do’s and Don’t’s (Part 1)

Comrades marathon is just around the corner and with the final days approaching the training is basically done, the fitness levels are banked and now all you can do is get to race day healthy, in good shape and ensure your nutrition and sleep is spot on over the next week because that is now going to be the biggest difference you can make on race day.

I am going to give you a number of tips on how to approach race day properly to guide you to your best day out.

Lets take a look at the important aspects of the final few days.

  1. The Do’s & Don’t’s
  2. Race Week Eating and the Carbo-loading debate
  3. The Hours Before Race Day
  4. Race Day Fuelling –  Carbohydrates, Hydration, Cramping and Caffeine

In this first part we talk about the basics and the Do’s and Don’t’s as we get closer to race day.

SLEEP
Sleep is without a doubt crucial. Its the time when the body needs to recover. Very often athletes underestimate the importance of sleep and the critical role it plays in sports performance. Sleep is the time where the body repairs and restores. Its a well know fact that “sleep deprivation leads to depression, high blood pressure, weight gain, heart disease, and probably mortality,” says Dr. Steven Feinsilver, the director of the Center for Sleep Medicine at Mt. Sinai School of Medicine in New York City. Additionally, a 2012 study detailed how sleep deprivation increases a person’s risk of developing Type 2 diabetes. Earlier studies have shown that reaction time nearly triples when a person pulls an all-nighter. Normally about a quarter of a second, it increases to 800 to 900 milliseconds. It’s about the same as the difference between being sober and being legally drunk. For elite athletes, emergency room doctors, and cab drivers, among others, losing that half of a second is costly never mind minutes over many hours due to the inability to focus due to poor cognitive function and physical fatigue.

If night sleep is still limited then try adding some power naps during the day. It’s been shown that taking in a large amount of caffeine before  power nap is best as consuming caffeine will eventually pass into the small intestine and get absorbed into the blood stream. It then begins a chemical reaction in the brain which blocks the receptors which are filled with Adenosine (energy transferring molecules) which actually cause drowsiness. Adenosine will make you feel very sleepy and by consuming caffeine the opposite happens when it binds to the receptors. This will trigger an effect of alertness and focus. Many people that have a power nap feel lethargic afterwards but the 20 minute coffee nap as we call it will allow you to rest for a nominal time with a feeling of energy after.

Over the next days you should ensure you give yourself complete focus on getting the most sleep you can each night to ensure your body and mind are ready for the big day ahead.

NUTRITION
The training now will be behind you but the nutrition is far from over. Training your gut, in other words eating correctly is paramount to arriving at your race healthy, in good shape and ready to tackle it.

Lets start with what you must avoid first in leading up to race day.

Lay off the Alcohol in Race Week
Make sure you hydrate properly. The recommendation is 30-40ml of fluid per kg of body weight and that is not by any means alcohol. Do not consume anything that would dehydrate you. If you do drink alcohol, keep it out of race week. It will impact you on race day, there’s absolutely no doubt. Alcohol pulls the fluid out of the system and dehydrates you and this is something you definitely want to avoid.

Avoid too much Caffeine
Coffee and tea can also have a diuretic effect and it would be advisable to keep this to a minimum. Stimulants also caused sleep disturbances and it would be best to keep these to mornings as opposed to afternoons to ensure you get a good nights sleep without any impact. If you plan on using caffeine on race day then it would be best to minimize your intake prior to race day to ensure you get the best benefit possible. Being overly tolerant to caffeine will minimize the effect it has during the race.

Avoid Eating Out
As much as possible try to ensure you are in complete control of your own nutrition. Eating out can put you at risk of digestive issues or potential illness. The more prepared you are and in control of your own eating the far lower the potential for any food triggering discomfort. Many athletes travel to foreign cities to race and in this case you should plan ahead and make sure you take with foods which you would generally consume and are used to. Trying foods because they are available and you don’t have a choice will only place you at risk. I’ve often seen people get stomach bugs close to an event due to eating out or consuming foods they are not used to.

If you could not find a hotel or accommodation where you have got the ability to self-cater it makes it a lot easier to take with your own food and not be stuck without decent options. If you are in a hotel and they’re not cooking foods to your liking, ask for foods that do agree with you or take a page out of my book where I go into the kitchen and do it myself or use powdered based foods where a hotel kettle is all that is needed to prep.

Avoid Overeating
Tapering for an event means lowered training volumes which equates to a lower calorie burn rate which means lowering your calorie intake and not over eating. This is one of the biggest mistakes athletes make in that they land up eating in excess of their calorie burn rate and actually land up gaining weight for race day. This is a problem as it means placing more stress on the body due to doing the event at a heavier than training weight which will only lead to issues and possibly more pain and suffering than you bargained for.

No to Sugar
Keep the sugar out of the nutrition equation please. Pastries, chocolates, sweets and other forms of sugars should be avoided as much as possible. It just creates havoc with the energy system and can trigger cravings leading to roller coaster riding, energy level dips and physical and mental fatigue patterns.

Avoid Processed Foods
Processed foods should be avoided at all costs. They mostly contain an abundance of unhealthy hydrogenated fats, sugars and additives which play havoc with the body. Opt for natural foods which provide benefit to the body and not foods that are detrimental to your over all health and well being.

Now lets take a look at what we should do leading up to the big day

THE DO’S

Eat Healthy
Eating nutrient dense meals which provide benefit are always the way to go. Incorporate a nice mixture of foods which are high in antioxidants, healthy carbohydrates such as nutrient rich vegetables and fruits, lean proteins and healthy fats to keep the immune system strong and the body energized.

Eat Consistently
Try to eat consistent regular meals as opposed to overly large gaps between the meals through the day. The body requires nutrients to keep it fortified as you head towards race day and its not a good time to place it into any form of starvation mode prior to a race.

Hydrate Constantly
Hydration is one of the most critical factors around any sporting event. To arrive at race day completely hydrated is important. You don’t want to be in a dehydrated state. You need to eliminate anything that would possibly dehydrate you as mentioned above anything such as diuretics excessive intake of stimulants such as caffeine and or alcohol certainly will.

Proper hydration requires regular fluid consumption preferably in the form of water or a hypotonic solution
