Study of body asymmetries in martial arts practitioners through electronic baropodometry

Abstract

Objective: the objective of this research was to analyze and compare the results of the asymmetries, by baropodometry between practitioners of Jiu-jitsu and Muay-thai.

Method: 15 practitioners of Muay-thai age 29.4 ± 6.3years, sport experience 8.5±4.0 years, body weight of 77.8 ± 12.5kg, height 178.2 ± 8.6 cm and fat percentage of 11.2 participated in this study. ± 4.9 and 16 Jiu-Jitsu athletes, age 32.2 ± 4.5years, sport experience 6.3±3.4 years. body weight 80 ± 9.6 kg, height 176 ± 5.2cm and fat percentage 10.5 ± 2.1. The present investigation carried out measurements of the pressure of the feet in a platform of baropodometry Tekscan® versão 5.1, with the participants in an orthostatic position. They were analyzed% force, force peak, pressure force. For the statistical analyzes the T Students was used for independent samples and to measure or level of significance the Effect Size was used.

Results: The athletes of both modalities presented similar average values in the evaluation by baropodometry, presenting significant differences between right side and left side, with higher values in% strength, being the highest Effect Size in the Muay-thai.

Conclusion: The bilateral asymetry happened between the two types of sports, therefore, with more emphasus on the Muay-thai group, possibly due tothe constant use of the feet when kicking with bouth the left foot and the right foot.
