The purpose of this study was to investigate the effects of different height of the insole into shoes on ankle muscle activities and gait performance in health young men. Fifteen health young adults spontaneously participated in this study. To examine the effects of different height (1 ㎝, 3 ㎝, and 5 ㎝) of insole in shoes during 10 ｍ walking, ankle muscle activities was measured by surface electromyography (EMG works 4.0, Delsys Inc., Boston, MA, USA) and kinematic parameters was measured by gait analysis system (GAITRite, CIR system Inc., PA, USA). For analyzing, statistical analysis was used one-way repeated ANOVA to know difference among 1 ㎝, 3 ㎝, and 5 ㎝ insoles during gait performance. The muscle activation of gastronemius lateralis was significantly different to different height insole into shoes during gait performance. However, there was no significantly difference on tibialis anterior, gastrocnemius medius, and soleus during gait. There was no significantly difference on gait velocity, cadence, dominant step length, dominant stride length, step width among three different height insoles during gait performance. The results of this study suggested that the height of insole into shoes would affect to ankle muscle activation during gait performance.
