正確なボールコントロール技術を妨げる過剰な筋活動量の定量化

抄録

This study was compared with an quantity of muscle activities between the skilled soccer players and the unskilled soccer players to verify the surplus muscle activities and the moderate muscle activities during the ball control. The performance test were made and evaluate accuracy of the ball control technique by its score. 21 skilled players and 19 unskilled players participated in this measurement. The skilled were divided by higher rank group and subgroup according to the performance test. The muscle activities of GAS (gastrocnemius) and TA (tibialis anterior) were recorded by electromyogram. The muscle activities of GAS of the skilled group indicated significantly lower values than the unskilled group (p < 0.05). The comparison between higher rank group and subgroup showed same result (p < 0.05). Additionally, in all subjects, there were significant correlations between the muscle activities of GAS and the score of test (r = -0.624, p < 0.05). In the skilled group, there were significant correlations, too (r = -0.612, p < 0.05). These results suggest that the skilled soccer player performs the ball control technique with fewer muscle activities of GAS than the unskilled soccer player. On the other hand, the unskilled soccer player performs the ball control technique with the surplus muscle activities and it may disturb the achievement of correct ball control technique. We concluded that it is necessary for good sport performance to remove the surplus muscle activities and show quantity of the moderate muscle activities.
