드롭랜딩 동작 시 시각제한에 따른 운동역학적 변인 비교분석

Abstract

The purpose of this study is to find out if there are significant differences in muscle activity in the eccentric muscle group(rectus femoris, gastrocnemius) when landing in the three visual conditions(both eye block, dominant eye block, non visual block). The subjects of the study randomly selected 10 male students attending S University of Seoul who have no musculoskeletal disorders that limit them from making drop-landing moves. For the measurement of the study, this study compared the maximum potential using the Telemyo 2400T System (Noraxon.USA). The results of the first study showed that the muscle activity of the renal muscle group (retus femoris, gastrocnemius) on landings did not differ significantly, depending on the visual changes. Second, according to visual variables, the average value of muscle activity of the retus femoris was higher both eye blocking condition than dominant eye blocking condition and the dominant eye blocking condition was higher than the visual non-blocking condition. Third, according to visual variables, the average value of muscle activity of the gastrocnemius muscle showed higher visual non-blocking conditions than the both eye blocking conditions, and the both eye blocking conditions were higher than the dominant eye blocking conditions.
