신유형의 뉴스포츠 적용이 어깨 근육 근기능과 악력에 미치는 영향

The purpose of this study was to investigate the effect of New-sports program on shoulder muscle function and hand grip strength. Thirty-one subjects with an average age 20.00 ± 0.58 years participated in our study. Upper trapezius and deltoid muscle functions of the dominant side were measured using a Myoton device and hand grip strength was measured using a hand dynamometer before and after intervention. We measured muscle tone, dynamic stiffness, and elasticity of the dominant upper trapezius and deltoid muscles. The upper trapezius muscle tone and dynamic stiffness decreased significantly after intervention but its elasticity increasedsignificantly in contrast, the deltoid muscle tone and dynamic stiffness increased significantly after intervention but its elasticity decreased significantly. However, grip strength did not change significantly after intervention. Thus, we conclude that application of a New-sports program can improve shoulder muscle function.
