106 students of the Faculty of Physical Education and athletes who train at the center of power arts (aged 18 to 30 years) have been investigated. The relation between the amount of lost and consumed liquid during physical activity has been studied. The amount of fluid lost was determined by the method of measuring the body mass of an athlete before and after the workout. The kinds of liquids used for eliminating dehydration have been analyzed. It has been revealed that while doing some physical activity and sports most of those being tested don't restore the lost liquid volume (with an average weight loss of 1,15 kg the amount of fluids they drunk was 0.91 l). In the given research the interrelation between the body weight and the lost liquid amount, and between the lost liquid amount and the kind of sports has not been exposed. Liquid loss of athletes in the medium intensive training process during the period of 1.5 h at the ambient temperature 21-22 degrees C constituted on average 1.53% of the body weight and didn't depend on the kind of sports. Despite the advantages of the athletic drinks are evident, the share of their consumption among the athletes in Russia is negligibly small. The great majority of respondents, namely 72%, use common or mineral water to restore the liquid. Only 6% of those being tested consume specialized athletic drinks. |
