Weight loss and dehydration in English Futsal players
Wednesday 01st February 2012 - Article 0
Futsal is a high intensity intermittent sport in which accelerations and short sprints are performed at maximal or almost maximal intensity, interspersed by brief recovery periods, during a period of time relatively long. Hydration is the word used to define the process of decrease in the amount of body water. Any activity that causes dehydration will provoke a decrease in the physical performance. An easy way to know the dehydration level of a sportsman is to weigh the subject before and after practising sport. The current study investigates the dehydration level of elite English male futsal players, in two games (i.e. friendly vs. official) and evaluates the resulting values by using studies available in the literature. Eleven (n=11) elite level male futsal players from a top-2 team competing in the Football Association (FA) Futsal National League volunteered to participate in this study. The anthropometric tests used were: mass, height and BMI. Body mass (kg) was recorded before the warm-up and after the game, the subjects wearing only underwear. Besides, the percentage of mass loss, activity time and sweating rate was also calculated. The average activity time was 48.18 ± 3.89 minutes (friendly game) and 48.18 ± 13.47 minutes (official game), with a mean mass loss of 1.27 ± 1.08 kg and 1.09 ± 0.94 kg, respectively. The mass loss percentage was 1.75 ± 1.53% and 1.47 ± 1.22%, respectively. The sweating rate was higher in the official game than in the friendly (11.17 mL/min and 10.44 mL/min). Significant differences were not found in the dehydration level between the two types of game in an elite level English Futsal team. Nevertheless, the results showed that these players obtained a dehydration level that could affect their performance.
