Abstract

The form of stationary cycling known as “indoor” or “spinning” is a high intensity aerobic activity frequently practiced in
fitness clubs. The high energy expenditure imposed to the practitioners leads to high production of sweat and consequently
to dehydration, which can affect gradationally in the performance. This study assess the impact of offering coconut water,
when compared with the ingestion of mineral water, in the hydration and the performance of practitioners, evaluated by
the before and after class grip strength. We examined 8 individuals from both sexes aging from 26 to 45 in a fitness club
in São Paulo. The study contemplated three phases of evaluation: non ingestion of liquids, ingestion of mineral water, and
ingestion of coconut water. We gathered anthropometrical data (body mass, height, BMI), hydration parameters (sweating
rate and percentage of water loss) and grip strength. We concluded that the sportsmen, despite of being submitted to light
dehydration, presented statistically significant improvement in their performance when ingesting coconut water, when
compared to mineral water. For future studies, it would be important to compare, using the same protocol, different sports
drinks, to determine an alternative nutritional prescription for the use of commercially available products routinely used
in fitness clubs.
