주관절 과신전 시 손목관절 변인이 상완이두근 활성도에 미치는 영향

Abstract

The study was conducted for the purpose of examining dynamic interaction which expansibility exercise caused by external power influences on muscles by analyzing variables of wrist joint through effects which wrist joint has on change of activity of biceps brachii during 2 segments and compulsive expansion motions through analysis of activation of muscles according to bending and stretching action of wrist joint. Whin compulsive expansion exercise of elbow joint, the effect of change of elbow joint angle and factor of wrist joint on activity of biceps brachii muscle was(F-5.23, P<.01) according to bending, standing neutral and stretching of wrist joint showing significant influence, and change of elbow joint angle greatly influenced on activity of biceps brachii muscle (F=13.09, P<.001), which means significant difference between them. The interaction between factor of wrist joint and change of elbow joint angle showed significant difference, verifying that tere was no effect of factor of wrist joint and change of elbow joint angle on activity of biceps brachii muscle(F=1.34, P>.05).
