Monitoramento das diferentes manifestações da força muscular em judocas durante um mesociclo competitivo

Abstract

Judo is a high intensity intermittent sport, and among its neuromuscular capabilities explosive strength, endurance strength and maximum strength stand out. The present study aims to analyze, through the handgrip and vertical jump tests, the behavior of the different forms of force manifestation in athletes during the weeks of a competitive mesocycle. The sample consisted of 12 judo athletes of both sexes (5 men and 7 women; age: 17.0 ± 1.0 years; weight: 69,4 ± 19 kg; height: 160 ± 5,0 cm; fat percentage: 14 ± 7,9 %). The experiments were performed daily over 3 weeks, in a room with constant temperature of 23º ± 1 and 60% humidity between 1 and 2 PM. The athletes took the maximum handgrip strength (MHS), handgrip strength resistance (HSR) and countermovement jump (CMJ) tests. For statistical analysis, the Shapiro Wilk and Levene test was used. For analysis of the variables over the weeks, a one-way repeated measures ANOVA was performed. If necessary, Bonferroni's post hoc was used. The variable MHS showed significant difference (F = 14.43; p <0.001), HSR also showed significant difference (F = 4.03; p = 0.03), both variables with significant difference in the third week in relation to weeks 1 and 2. However, the CMJ values did not show significant differences (F = 2.88; p = 0.07). It was possible to observe that the manifestations of force analyzed had different behaviors. Each form of training within judo generates different types of fatigue. The predominance of some form may have led to different types of recovery, which may justify the dissimilar behavior of the forces in the current study.
