Abstract
Introduction: In our experiment, we wanted to establish to what expert the isotonic drinks infl uence the results of the athletes running a semi-marathon (21 km). Material and Methods: The study included 40 persons who ran in the semi-marathon (21 km). According to their fitness we divided them into 2 groups. The athletes who run more than 30 km a week were included in the trained group and those who run less than 30 km were included in the nontrained group. We chose 10 persons from each group who drank isotonic drinks and 10 who drank only water. During the race, the runners had to drink to same amount of liquid. In the first part of our experiment we asked the participants to complete a questionnaire with 29 questions. They were asked about their training level, if they know anything about dehydration if they had already experienced its symptoms. In the second part of the experiment we took urine samples before and after running and we measured the quantity and changes of the liquid as well as the compounds of the body. From the results, we tried to establish how much the sportsmen dehydrated during the race taking also into consideration the different liquids they drank. Results: 80% of the sportsmen from both groups, trained and non-trained, who drank isotonic drinks reported less symptoms of dehydration in comparison with those who drank only water during the semimarathon. We could establish the final results from the questionnaire what the runners completed after the race. The study of the body compounds also certified that the athletes who drank the isotonic drinks were less dehydrated. They lost only 1% of their body water. The sportsmen who drank only water all showed dehydration at different levels, the highest one being almost 5% of the body water. The density of the urine showed similar values. The density of the urine of those who drank only water more significantly (p<0.05)
