The aim of this study was to investigate simultaneous changes in EMG pattern during learning dart skill in dominant and non-dominant hands. The samples consisted of 10 non-athlete students with an average age of 23±2.5, which were divided into two group dominant hand (5) and non-dominant hand (5). Repeated measures ANOVA were used to measure data at the execution level and changes in EMG activity. The results showed a significant decrease in the absolute error of dart throwing at the performance level and an increase in EMG activity at the muscle level along with a decrease in muscle co-contraction in the acquisition and retention stages in both groups (P<.05). Also, there was no significant difference between EMG activity in the dominant and non-dominant hand groups after skill acquisition (P>.05). Generally, the results of this study showed that along with relatively constant changes in performance during dart skill learning, relatively constant changes in EMG patterns also occur, so that the concept of motor learning is also observed at the muscle level. Also, the results of this study supported the existence of the same motor program for dominant and non-dominant hand control, even in the conditions of bilateral transfer control.
