Abstract

The purpose of this study is to compare and evaluate the balance and muscle activity after having performed balance exercise at different ground conditions. The subjects were divided into 3 groups; Sand Group(SG)(N=30) and Balance Form group(BFG)(N=30), Hard Ground Group(HGG)(N=30). The period of intervention was for six weeks. EMG for Tibialis anterior(TA), Soleus(So), Biceps femoris(BF) muscle activity, Air-balance system 3D were used as evaluation tools for this study. the change of balance ability and TA, So muscle activity was greater in the SG, BFG than HGG which may imply that sand can be used for the balance exercise like any other ground.

본 연구는 균형운동 시 모래지면, 균형매트, 단단한 지면의 차이에 따른 균형능력 및 앞정강근, 가자미근, 넙다리두갈래근 근활성도의 변화를 알아보고자 실시하였다. 건강한 성인 남녀 90명을 무작위로 모래지면군, 균형매트군, 단단한 지면군으로 구분하여 세 그룹 모두 동일한 운동 프로그램을 서로 다른 지면에서 6주간 실시하였으며, 운동 전 후에 Air-balance system 3D를 통해 8방향별 체중이동 각도값과 표면근전도를 통해 근활성도를 측정하였다. 그 결과 두 그룹(모래지면군, 균형매트군) 모두 단단한 지면군에 비해 균형능력과 앞정강근과 가자미근의 근활성도가 더 향상되었음을 알 수 있었다. 이를 통해 모래지면의 불안정 지지면으로써 가능성을 확인할 수 있었다.
