Avaliação do tempo de reação motora em atletas de MMA antes e após treino de combate: estudo descritivo transversal observacional

Abstract

The aim of the study was to investigate the impact of fatigue on motor reaction times for punches and kicks in MMA athletes after combat training in the municipality of Coari-AM. This was a descriptive cross-sectional observational study. The study consisted of 18 MMA athletes aged between 18 and 29 years old. The participants were assessed by comparing the difference in motor reaction time for punches and kicks before and after combat training using the TReaction app, as well as comparing the findings of each group in relation to their weight category. The normality of the data was analyzed using the Shapiro-Wilk test. Differences were verified using the Wilcoxon test and the groups were compared using the Kruskal-Wallis test and the Dwass-Steel-Critchlow-Fligner post hoc test, with a significance level of p < 0.05. There was a statistically significant difference (Z: -2.069; p < 0.05) between the motor reaction time of the punch before (MD: 282; AI: 0.176) and after combat training (MD: 439; AI: 0.259). In the assessment of the kick, there was no statistically significant difference (Z: -0.196; p > 0.05) between the motor reaction time of the kick before (MD: 447; AI = 0, 323) and after combat training (MD: 430; AI: 0.266). When the groups were compared by weight category, there was no significant difference between the groups. It can be concluded that training for MMA fights may alter the motor reaction time of athletes related to the upper limb, but not related to the lower limb, and the weight category does not interfere with motor reaction time.
