There is a tremendous need for a sports drink formulated specifically for the heat to e load is that drink! We could say that your sports drink has many important physiological "jobs", but in the heat, the most important job of your sports drink is prevention and control of heat stress, primarily by replacing sweat electrolytes and fluid as they are lost. If electrolyte balance is maintained within, and you supply enough fluid to replace losses (see our Nutrition Calculators) you are well on your way to success in the heat!
Dextrose, the principal carbohydrate in e load, is a high glycemic carbohydrate that is rapidly absorbed and yields instant energy. Additionally, dextrose is the carbohydrate of choice for a sports drink made to combat heat stress. The biggest reason for this is that dextrose actually facilitates sodium absorption from the small intestine, unlike other carbohydrates. This is why many oral medical rehydration solutions contain dextrose as the principal carbohydrate. Also, the presence of dextrose and sucrose together may enhance each other's absorption (enhanced 'solute flux'), and maybe more important than the osmolality of the carbohydrates themselves.

e load is a physiologically formulated sports drink with the emphasis on four important performance factors:
- Optimum hydration, facilitated by higher sodium levels
- The most effective replenisher of sweat electrolyte on the market today, countering the depleting effects of sweating, and providing an important weapon against the development of heat illness
- Rapid fueling with its primary carbohydrate, high glycemic index dextrose, reducing the chance of bonking
- Buffering lactic acid production with MultiCitrate
e load can and should be used during both pre-exercise and exercise phases.
The use of e load prior to activity is an important way to ensure that you are physiologically ready to perform, addressing the following:
- Electrolyte Depletion
The purpose of preloading is to make sure that no water, electrolyte or carbohydrate deficits exist prior to starting. Starting your activity dehydrated, electrolyte depleted or relatively hypoglycemic with reduced glycogen stores will limit performance for sure! e load is also ideal for rehydrating after a night's sleep and before a morning training session or race-early morning dehydration is the norm after your typical night's sleep.
Regarding when, we suggest using e load up to one hour before activity, thus giving yourself time to urinate if necessary. You can also sip e load within 15 minutes of starting to ensure that you start with some fluid in your stomach, thus facilitating stomach emptying during your event. Regarding how much, if in the morning, you must drink back what you have lost overnight in terms of water. Weigh yourself before going to bed (after urination) and upon arising (after urination). Each kilogram (2.2 pounds) deficit equals one liter. For optimal rehydration in the morning, drink 1.5 times this volume of fluid back up to one hour before activity is to begin. The added amount in the 1.5 times ratio helps compensate for some of the fluid which will inevitably be urinated. For example, if Sharon weighs 63 kilograms before retiring (after urination), and 61 kilograms upon arising (after urination), she has a deficit of 2 kilograms (4.4 lbs.), or 2 liters of fluid. Ideally, she should ingest up to 3 litres of e load up to one hour before starting activity.
With start times occurring at other times of the day, after your morning rehydration is complete, we suggest drinking 10 - 15 ml of e load per kilogram body weight (5 - 7 ml per lb.), again up to one hour before starting.
For example, if Sharon generally weighs 65 kilograms, and her activity is to start later in the day, after her morning rehydration is complete, she ideally should consume 65 x 10 = 650 ml to 65 x 15 = 975 ml of e load up to one hour before starting activity.
Use of e load during your activity is important to:
- maintaing hydration
- maintain electrolyte balance
- contribute to carbohydrate balance, reducing the chance of bonking
- buffer lactic acid as it is produced
How much to ingest entirely depends on how much you are sweating, and for help in figuring this out, please refer to our Nutrition Calculator section. In short, if you sweat one liter per hour in the conditions in which you are exercising, than you should try to replace these losses at a maximum of this rate, in order to optimize hydration and to balance sweat electrolyte losses.
For example, Sharon is running 20 miles today, with a temperature of 90ﾧ F and 35% humidity. Before she starts, she weighs 65 kilograms (143 pounds). After she finishes, she weighs 63 kilograms (139 lbs.). She also drank 2 liters of e load during the run, which equals 2 kilograms - this must be added back. See ourNutrition Calculators for further help with these calculations.
Therefore, she lost (65 - 63) + 2 = 4 kilograms or 4 liters of fluid. Lets say Sharon did this run over 3 hours. She therefore lost 4 liters in 3 hours, or 1.33 liters per hour.
Finally, the question of whether or not you need to FULLY replace all lost fluid is still under investigation. Likely, however, full replacement is not completely necessary, in cooler to moderate temperatures especially (i.e. up to 22ﾧ C), as up to 2% dehydration may be tolerated by some without substantially impairing performance (43). Using this figure, it is possible to calculate a minimum fluid need per hour for use during more moderated temperatures. For details, please see our Nutrition Calculator section.
However, "when exercising in a hot environment ( > 30 degrees C), dehydration by 2% of body weight impairs absolute power production and predisposes individuals to heat injury"(43). It is therefore recommended that as much as possible during hot weather activity, you endeavour to replace as close to the volume of fluid you are losing as possible.
- ultra filtered whey protein for enhanced glycogen restoration and tissue repair,
- high glycemic index dextrose for accelerated glycogen restoration,
- Vitamin C in low acidic Ester C format for antioxidant support,
- physiological and research proven levels of sodium, to accelerate rehydration and sodium repletion, and,
- potassium, calcium, magnesium and zinc to help replace other valuable sweat electrolytes.
Il y a un énorme besoin de boisson pour sportifs spécialement conçue pour la chaleur et eload est la boisson! Nous pourrions dire que votre boisson sportives a plusieurs tâches physiologies, mais dans la chaleur, la plus importante tâche est la prévention et le contrôle des stress de chaleur, principalement en remplacement les électrolytes et liquides perdus lors de la transpiration. Si l'équilibre électrolyte est maintenue, et que vous apporter suffisamment de liquide pour remplacer les pertes, vous êtes sur la voie du succès dans la chaleur!
Le dextrose, le principal glucide dans eload, est un glucide hautement glycémique qui est rapidement absorbé et libère de l'énergie instantanément De plus, le dextrose est le glucide de choix pour une boisson sportive faite pour combattre les coup de chaleur. La plus grande raison pour cela est que le dextrose facilite l'absorption du sodium dans le petit intestin, contrairement aux autres glucides. C'est pourquoi plusieurs solutions de réhydratation orales contiennent du dextrose comme glucide principal. Aussi, la présence de dextrose et de sucrose ensemble peut améliorer l'absorption de l'autre (flux de soluté amélioré), et peut-être plus important que l'osmolalité des glucides eux-mêmes.
