Summary

It is well-established that exercise has many health benefits. During exercise in temperate/hot conditions, sweating is necessary to dissipate heat. This sweating typically results in dehydration, which may impair physical and mental performance. Therefore, following exercise, effective rehydration is important to restore an optimal hydration state and therefore physical and mental performance. If an individual only rehydrates with water, though, it is unlikely that they will fully rehydrate as plain water is not very well-retained by the body, due to its lack of carbohydrate and electrolytes. For this reason, sports/ hydration drinks are likely to aid in better rehydration, due to their carbohydrate and electrolyte content. This project aims to compare the rehydration effectiveness and glucose responses to two sports / hydration drinks and water (with different carbohydrate and electrolyte contents).

Conditions

• Dehydration

Interventions

Type	Name	Description
OTHER	Water	Consumption of a water volume (from water) equal to 150% of body mass loses from exercise-induced hypohydration
OTHER	Glucose-based sports drink	Consumption of a water volume (from a glucose-based sports drink) equal to 150% of body mass loses from exercise-induced hypohydration
OTHER	Fruit beverage	Consumption of a water volume (from a fruit beverage) equal to 150% of body mass loses from exercise-induced hypohydration
