PURPOSE: This study aimed to examine the evaluation of muscle activity, muscle fatigue and balance in male high school Taekwondo athlete with a deformity of the medial longitudinal arch.
METHODS: The 20 male high school Taekwondo athletes participated in the study they have been measured radiographic a medial longitudinal arch and divided into a medial longitudinal arch group (higher than 18.8°; MLA group, n = 12) and control group (lower than 18.8°; CON group, n = 8). All subjects were measured muscle activity (TA, PT, PL and PB), muscle fatigue (TA, PT, PL and PB) and balance (A-, AL-, L-, PL-, P-, PM-, M-, AM-direction and composite score; CS).
RESULTS: The muscle activity of TP was significantly higher in MLA group compared to CON group (p = 031) and the muscle fatigue of TA was significantly lower in MLA group compared to CON group (p = .043). However, balance did not show significant differences between the groups.
CONCLUSION: These results confirmed that male high school Taekwondo athlete with a deformity of medial longitudinal arch increase TP and decrease TA, but there was no difference on balance.
