A influência da reposição hídrica na percepção subjetiva de Esforço em praticantes de muaythai

Abstract

Muaythai is a martial art of Thai origin that has been gaining many supporters today. During the training of the martial art a series of physiological responses are generated in the practitioners. Hydration is essential for the maintenance of various functions of the human body before, during and after training. The objective of the present study was to compare the subjective perception of effort (PSE) of Muaythai practitioners in sessions of training without hydration and with hydration. Fifteen adults of both sexes participated in the study, with a mean BMI of 25.41 (± 2.79) and mean practice time of 4.01 (± 3.01). For the data analysis, a descriptive statistic was used, the Shapiro-Wilk test to verify normality, the Man-Whitney U test with p value <0.05 to compare the results of the exercises (without and with hydration) and Spearman test with p <0.01 to correlate practice time, PSE, total recovery quality (TQR), percentage of weight loss and sweating rate, the program used was the Statistical Package for Service Solution 20 (SPSS). The results found for the comparisons of training with and without hydration in PSE, percentage of weight loss, sweating rate and TQR, did not show significant differences. negative correlation was found between the time of practice and PSE (-0.724) and a positive correlation between the percentage of weight loss and the rate of sweating (0.925). It was identified that training of mild and moderate intensities to PSE does not change in the absence or absence of hydration. It is also suggested that new studies be performed at different times, more intense exercises and with more people.
