Effect of hydration with beer of different alcoholic content and mineral water on speed in amateur athletes

Abstract

Beer is often used after exercise when socializing. The aim of the present study is to verify the impact of hydration with mineral water (MWG), low carb beer (LCBG) and regular beer (RBG) on performance in the speed test performed on the following day. Thirty-one male participants were analyzed, with 22.77 ± 3.10 years of age, 16.0 ± 0.61% of fat, 72.70 ± 14.81 kg, 12.39 ± 6.50 kg of mass. fat and 62.7 ± 9.7 kg of lean mass. All were physically active, played soccer or futsal regularly for at least six months, in addition to having no diagnosed joint or muscle injuries that could impair performance in games or speed tests. After the physical evaluation, the players warmed up with the ball for 10 minutes, then performed three 30-meter shots to determine the speed with a five-minute interval between them, the best time was adopted for analysis. The difference between the speed test the next day minus the time in the test before the game was used for analysis (delta). The delta time of the speed tests was 0.06 ± 0.38 seconds in the MWG, 0.08 ± 0.37 seconds in the LCBG and 0.31 ± 0.22 seconds in the RBG, without showing any significant difference between the groups. Finally, the present study indicates that doses as low as 1% of body mass in beer with an alcohol content of 3.8% or 5% do not affect sports performance the next day.
