초록

본 연구에서는 선 자세에서 팔굽관절 각도에 따른 악력과 위팔노근의 두께 변화를 확인하여 팔굽관절 각도가 악력에 미치는 영향을 알아보고자 하였다. 연구를 위해 건강한 대학생 30명을 선별한 후, 선 자세에서 팔굽관절 $0^{\circ}$, $90^{\circ}$, $135^{\circ}$ 굽힘을 취하게 하고 각각의 최대악력과 위팔노근 두께를 전자악력계와 초음파 영상 진단 장비를 이용하여 측정하였다. 그 결과 남자 대학생과 여자대학생 모두 팔굽관절 각도가 $0^{\circ}$일 때 악력이 가장 컸으며, 각도가 증가할수록 악력이 감소하였으나, 통계적으로 유의미한 차이는 없었다(p<.05). 남자대학생과 여자대학생 모두 팔굽관절 각도가 $0^{\circ}$일 때 위팔노근의 두께가 가장 작았으며, 각도가 증가할수록 위팔노근의 두께가 증가하였으며 통계적으로 유의미한 차이가 있었다(p<.05). 본 연구의 결과를 통해 팔굽관절 각도변화가 악력에는 큰 영향을 미치지 않으나, 위팔노근의 두께에는 영향을 미친다는 것을 알 수 있었다.

This study is investigated for angle of elbow joint influence on grasp strength, confirm change of grasp strength and brachioradialis thickness according to angle of elbow joint in standing. Thirty male and female university students, who participated with agreement in this study, using for electronic dynamometer and convertible ultrasound measure maximum grasp strength and brachioradialis thickness after elbow joint $0^{\circ}$, $90^{\circ}$, $135^{\circ}$ positioning in standing. In average grasp strength was strongest at elbow joint $0^{\circ}$, as the angle of elbow joint increased, was decreased grasp strength, no significant statistically(p<.05). In average brachioradialis thickness was lowest at elbow joint $0^{\circ}$, as the angle of elbow joint increased, was increased brachioradialis thickness, significant statistically(p<.05). These result may indicated that change of elbow joint angle not influence on grasp strength, but influence on brachioradialis thickness.
