Hot Weather Training: Hydration Hacks to Maintain Peak Performance

Working out in the heat has its own set of unique challenges and factors that differ from training on more moderate days.  One usually does not have much to consider by means of temperature when training in an air conditioned gym.  However, many athletes prefer outdoor workouts, and these workouts may only be accomplished in high heat.  What is the best way to manage the body when under such environmental strain?  How can heat affect the body and what can athletes do to mitigate its effect?

What Constitutes Hot Training?

There are three primary factors that define hot weather training: temperature, sun exposure and humidity.  The presence of one or multiple of these elements can seriously degrade an athlete’s performance if not accounted for and mitigated.  While these aspects are found outside, hot studios, too, can manufacture temperature and humidity.  The athlete must take measures in either environment to best stave off negative effects.

Temperature

Temperature is the most prominently considered factor for hot weather training, and for obvious reasons!  The higher the temperature, the more of an effect the temperature will have on one’s body.  Even if clouds are covering the sun, if the temperature is high, the athlete’s body will be working harder to compensate.

Sun Exposure

With higher temperatures comes sun exposure.  Training in the direct sunlight is good for the body, yet can become increasingly challenging.  Even if the athlete is running through patches of shade, the time spent in the sun will directly impact his performance.

Humidity

Humidity is the most underrated factor of hot weather training.  When checking the weather, often the only factor considered is temperature.  While obviously important, the level of humidity also directly affects the athlete’s performance.  With more humidity comes a higher perceived heat, which can degrade performance if not properly considered.  

What are the Effects on the Body?

Hot temperature and high humidity may feel uncomfortable for some, or enjoyable for others.  Despite one’s preference for the weather, it will have effects on the athlete’s body when working out.  Each aspect of hot weather training will need to be considered before the athlete begins his training.  Failure to do so can easily lead to a host of negative effects that will only set the athlete back in his goals and plans.

Temperature

The higher the temperature, the more sweat the athlete’s body will produce.  This can lead to quick dehydration, early fatigue, lightheadedness and/or muscle cramps.  The athlete may feel as if he must work two times as hard to perform as he can during a more moderate day.  This increased perceived exertion may cause the athlete to lose adherence to his program, especially if he feels that previous results cannot be reached.

Sun Exposure

Increased time in the sun can, too, create more sweat for the athlete, leading to dehydration and the related effects that come alongside.  If not properly accounted for, prolonged sun exposure will cause sunburns that will undoubtedly hinder performance.  With more sun on the skin comes a higher cardiovascular load as one’s heart rate increases.  As the body heats up rapidly in the sun, more carbohydrates will be burnt, ultimately leading to an intense, fatigue-ridden crash.

Humidity

Humidity, like temperature and sun exposure, will increase the internal temperature of every athlete.  This increased temperature will hinder power output and cause early-onset fatigue.  Similar to sun exposure, a higher heart rate will result, leading to an increased perceived exertion.  On a hot day, the sun and overall temperature will heat up the athlete’s while the increased humidity will trap the heat in the body.

How Best to Mitigate Hot Weather

One need not hide in one’s home when the sun is out–there is no better training time than warm, sunny days!  However, some measures should be taken to ensure a healthy and successful training environment.  If possible, structuring one’s outdoor workout around the heat of the day can be especially helpful.  Additionally, choosing the right clothing for certain activities will allow for better cooling.  Hydration is essential for daily life, but must be prioritized when losing much sweat.

Timing

One cannot always control a daily schedule, but if possible, moving one’s workout around the hottest hours of the day will avoid the hours that can cause the most stress on the athlete.  Working out in the early evening instead of the afternoon, for example, will allow the athlete to push harder in the workout.  If evening training is unavailable or not preferred, opt instead for early morning workouts.  Beating the heat will allow the athlete to avoid early fatigue and have successful training sessions.

Clothing

Choosing the right clothing can make the difference between quick fatigue and proper workouts.  Heavy, non-breathable fabrics trap the heat against the body.  Added to prolonged sun exposure and high humidity, the individual will have to end the workout early to avoid the more severe effects of dehydration.  Wearing lighter fabrics with lighter colors will allow heat to wick off the athlete, delaying fatigue and helping the body to cool.

Hydration

The athlete must prioritize hydration during all times of the day, however, this need is heightened when working out in hot weather conditions.  Consuming lots of water and electrolytes will stave off the effects of dehydration.  Without enough hydrating liquids in one’s system, muscle cramps and fatigue are likely to begin.

How to Avoid Dehydration

Dehydration is the greatest risk with hot weather training.  The body’s temperature rises and more sweat is produced. Through this sweat, key electrolytes are lost.  Without these electrolytes, fatigue and all related effects are likely to begin.  To avoid dehydration, enough water must be consumed (obviously!).  Additionally, electrolyte supplementation will prove to be essential when sweat levels are high.  Essential Amino Acids are not often considered necessary for hydration, however, they prove to be quite useful in the process of rehydrating the exhausted athlete.

Water

Drink more water!  With more water in one’s system, electrolyte levels will remain balanced for longer and one’s lean mass will be able to properly contract during training sessions.  It is possible to drink too much water, which can cause gastrointestinal discomfort and bloating.  The best practice for any hot weather training session is to consistently sip on water throughout the workout.

Electrolytes

Electrolyte supplementation is crucial for replenishing what was lost through sweat.  Water is usually sufficient for training, however, hotter temperatures and higher humidity will cause the body to lose more electrolytes during hot weather training.  In these scenarios, supplementation will serve to directly benefit the athlete’s performance and overall health.

EAAs

Essential Amino Acids are the building blocks of muscle–the protein that muscle is made from consists of EAAs.  While EAAs have been clinically studied for their effects on improving lean tissue, not many athletes see their benefit for hydration.  EAAs indirectly support sodium transportation and improve fluid retention in one’s muscle mass, supporting overall hydration.

Best Products for Hydration

When seeking to hydrate for performance-related activities, many stick solely with water or seek a multitude of sports drinks.  Water often is enough for hydration, but it can fall short when one is working hard in hot weather.  With this in mind, athletes try to compensate for lost electrolytes through sports drinks.  Are these effective, or is an all-in-one supplement the best choice for athletes?

Water

By all means, water is enough to hydrate every individual.  However, when temperature is hot and humidity is high, the body has to work harder to fuel one’s muscle mass.  In this scenario, water may not be able to sufficiently replace the amount of electrolytes lost.  Athletes may then turn to sports drinks to replenish lost electrolytes.  Is this the most efficient form of hydration?

Sports Drinks?

The typical sports drink is full of artificial coloring and artificial ingredients.  Many sports drinks are filled with sugar in an effort to give the individual a perceived energy boost, even while it leaves the athlete with an intense, fatigue-ridden crash.  On top of this, most sports drinks promote their electrolyte benefits while only containing two electrolytes (sodium and potassium).  These electrolytes are needed for hydration, but a fuller profile of these minerals is necessary for actual hydration.

An All-in-One Supplement

Our Muscle Synthesis Activator has not only sodium and potassium, but three more key electrolytes meant to fully hydrate the tiring athlete.  During a workout in the heat, our MSA will provide electrolytes more sufficiently than water and more efficiently than sports drinks.  Alongside these electrolytes are all nine Essential Amino Acids, supporting intracellular fluid levels and sodium transport through the athlete’s body.

Oh!mino and Hot Weather Training

Oh!mino provides the individual with the all-in-one supplement meant to keep athletes hydrated.  Our Muscle Synthesis Activator will fight fatigue and give athletes the strength needed to push hard in warm weather.  Even so, it is vital to recognize and act under one’s limits.  Our MSA will support the athlete with hot weather training, but only to the extent that it is safe to train!

Timing and Dosage

Our Muscle Synthesis Activator works the best when one or two scoops are taken 30 minutes before training, one scoop consumed throughout the workout and one or two scoops within 30 minutes of finishing the session.  If the heat is particularly intense or workout especially difficult, taking more scoops of our MSA as needed will only enhance one’s performance (we offer caffeinated and stimulant-free, catering to your energy needs). 

Effects

With a full panel of Essential Amino Acids and five key electrolytes, our MSA will fight fatigue and encourage optimal strength output during any workout.  Dehydration is a true risk during hot weather training; it can cause a host of negative symptoms that will invariably impair performance.  Our EAAs and electrolytes will fight these symptoms by sufficiently hydrating the training athlete. 

Know Your Limits!

Even with plentiful water, scoops of our Muscle Synthesis Activator and lightweight clothing, it is vital to stay within safe limits.  If one’s training regimen is simply too intense for the current weather, it may be wiser to wait.  Electrolyte supplementation is useful insofar as the athlete is training within mindful limits.  Be smart about when, where and how one trains; the athlete will yield the best results with sufficient supplementation and a proper training environment.

Frequently Asked Questions (FAQs)

How much water should an athlete consume during hot weather training?

The average needs are between 16-24oz of water per hour in hot weather training, yet these needs will vary based on heat and sweat rate.  Drinking 16-24oz of our Muscle Synthesis Activator during training will hydrate more efficiently than water alone, as it contains five key electrolytes lost through sweat.

What are the early warning signs of dehydration?

Early-onset fatigue is one of the most common warnings of dehydration, alongside headaches, a dry mouth and a weakened strength output.  As true dehydration sets in, these symptoms will worsen and other effects will crop up: muscle cramps, lightheadedness and/or a racing heart.

Should athletes adjust intensity when training in extreme heat?

Yes.  If the weather is too hot and the training too intense, the athlete should adjust his workout plan accordingly.  Shortening overall training and/or extending rest periods may be necessary.

Are there ways to improve heat tolerance over time?

As the athlete trains more often in the heat, his body will acclimate to the hot weather.  Even so, it is wise to moderate one’s workout in warm temperatures even with a history of hot weather training.

How does dehydration affect post-workout recovery?

Dehydration will elongate post-workout recovery, leading to slower muscle synthesis and a weakened strength output in the athlete’s next training session.
