MECHANICAL ANALYSIS OF SUPPORTING LEG DURING ROUNDHOUSE KICK IN MUAY THAI BEGINNERS
The purpose of this study was to analyse and compare the mechanics of dominant and non-dominant supporting leg while executing the roundhouse kick of beginner level Muay Thai exponents. Ten male Muay
Thai beginners (20 ± 1 years old) participated in this cross-sectional study. All participants were allowed to familiarize and perform three trials of the roundhouse kick for each leg. An infrared motion analysis 3D system and force plate were used to compile the kinematic and kinetic data of the supporting leg from the roundhouse kick. The Descriptive Statistics and Mann-Whitney U test was leveraged by the researcher to compare the difference between selected parameters as moment of hip, knee, ankle joints and ground reaction force that effect on supporting leg, respectively. The results of study revealed that there was antero-posterior GRF and support leg joint moments of supporting dominant leg significant difference level at 0.01. The findings of this study demonstrated the important data for the Muay Thai beginners to enhance the control of their dominant support leg when executing a better roundhouse kick.
