[Purpose] The purpose of this research was to examine differences in muscle activity between the resting forearm position (RFP) and the straight forearm position (SFP) during upper arm strengthening exercises. [Participants and Methods] In total, 35 healthy college students were randomly sampled (18 males and 17 females). Surface electromyography data were collected from the medial and lateral sides of the biceps and triceps brachii muscles. [Results] The medial muscles showed greater activity during SFP versus RFP, but no difference in overall activation was found between the two positions. [Conclusion] Carrying angle less affected to biceps and triceps brachii muscles activation during upper arm strengthening exercises.
[目的] 本研究旨在探讨上臂强化训练期间，静息前臂位置（RFP）和直臂位置（SFP）之间肌肉活动的差异。[参与者与方法] 总共随机抽取了35名健康大学生（18名男性和17名女性）。从肱二头肌和肱三头肌的内侧和外侧收集表面肌电图数据。[结果] 与RFP相比，SFP期间内侧肌肉表现出更大的活动，但两个位置之间的总体激活没有差异。[结论] 在进行上臂强化训练时，提携角对肱二头肌和肱三头肌的激活影响较小。
