점핑활동 프로그램이 다운증후군 아동의 하지 근력 및 자세조절 전략에 미치는 영향

Abstract

The purpose of this study was to suggest jumping activity program for increasing the leg strength and postural control strategy and to identify the effects of the jumping activity program. Participants were twelve male elementary school students with Down syndrome(exercise group: n=6, non-exercise group: n=6). The jumping activity program administrated during 8 weeks, 3 times a week, for 70 minutes at a time. The isokinetic strength variables and postural control strategy data were analyzed using t-tests(α=.05) to identify difference of means within each group. In conclusion, most of all the isokinetic strength and postural control strategy variables of participants in the exercise group were increased. Therefore, this study suggests that through the participation of jumping activity program children with Down syndrome at the age of 7∼13 will stabilize their joints surrounded by muscles, increase the strength of their lower limb, and maintain the posture by increasing muscle reaction speed between lower limb and trunk.
