SILVA, Mara Reis et al. Effects of a carbohydrate-electrolyte drink on the hydration of young soccer players. Rev Bras Med Esporte [online]. 2011, vol.17, n.5, pp. 339-343. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86922011000500009.
The hydration status of nine male under 18 soccer players was evaluated after ingestion of the most accepted carbohydrate-electrolyte drink between three tests. The study was conducted during 80 minutes of training. The soccer players ingested 900 mL of a commercial carbohydrate-electrolyte drink (control) plus 300 mL of water or 900 mL of the most accepted drink (test) plus 300 mL of water. The time of training, exercise intensity, urinary status, weight, weight loss, the weight loss rate, the dehydration degree and the sweat rate were determined to verify the hydration status. The drink with 8% carbohydrate was the best accepted. The exercise intensity of the players was higher on the days that they ingested the tested drink. The time of training in relation to the tested drink was significantly lower than the control beverage (p = 0.008). The weight loss, the dehydration degree and sweat rate of the athletes with fluid intake test was higher when compared to control fluid intake. The athletes completed the game more dehydrated with the drinking fluid test; however, the limit of 2% weight loss was not exceeded. The exercise intensity (mild to moderate) and climatic conditions (lower temperature and higher relative humidity) on the day of the fluid control intake control may have helped the best results from the hydration capacity of the fluid control.
