폼롤러를 이용한 일회성 자가근막이완이 중학교 배드민턴 학생선수의 하지 근기능에 미치는 영향

Abstract

The purpose of this study was to evaluate compare the acute effects of self-myofascial release(SMR), static stretching(SS) and no stretcing(NS) used as part of warm-up on muscular functions of elite badminton athletes in middle school. The subjects were eight male badminton athletes The subjects were classified into three group; SMR group, SS group and NS. The subjects visited three times at two week intervals. All subjects were tested for body composition, physical fitness factors, wingate test, and isokinetic knee functions. Statistical analysis was performed using One-way ANOVA. As the result of this study, in the vertical jump, the SMR group(p=.005) was significantly higher than the NS group and the SS group. In addition, the SMR group was significantly higher than the SS group for backward flexibility(p=.016). The SMR group(p=.021) was observed a significantly higher dynamic balance than the NS group. In the wingate test, the relative average power was significantly higher in the SMR group (p=.014) than in the SS group. The isokinetic knee muscle strength was significantly higher in the SMR than in the SS in 60°/sec(PT) Right:extension(p=.014) and 60°/sec(%BW) Right:extension(p=.026). The 180°/sec(AP) was significantly higher in the SMR than in the SS and NS in Right:extension(p=.012). The 180°/sec(%BW) was significantly higher in the SMR than in the SS in Left:extension(p=.019) and Right:extension(p=.013). In conclusion, it is thought that SMR treatment before exercise may increase lower body muscle function in badminton players.
