[Purpose] This study assessed the exercise capacity of healthy adults while performing the inline lunge exercise by using Functional Movement Screen (FMS). Compared the difference in muscle activity of the quadriceps according to the exercise capacity. [Participants and Methods] Thirty two healthy participants (12 males, 20 females) participated in this study. The surface electromyography (sEMG) was used to measure the electrical activities for the vastus medialis (VM), rectus femoris (RF), vastus lateralis (VL) of quadriceps. [Results] Both groups had significant difference when sitting up and getting up during the inline lunge. In scores 3 group, vastus medialis showed higher muscle activity than vastus lateralis. On contrary, in scores 2 group, vastus lateralis had higher muscle activity than vastus medialis. [Conclusion] Therefore, this study suggests that inline lunge can help to strengthen the quadriceps effectively by showing the difference of quadriceps activity according to exercise capacity.
[目的] 本研究通过功能性动作筛查（FMS）评估健康成年人进行箭步蹲运动时的运动能力。比较根据运动能力不同，股四头肌肌肉活动的差异。[参与者与方法] 32名健康参与者（12名男性，20名女性）参与了本研究。采用表面肌电图（sEMG）测量股四头肌内侧肌（VM）、股直肌（RF）、股外侧肌（VL）的电活动。[结果] 在箭步蹲过程中，两组在坐起和站起时均存在显著差异。在得3分的组中，股内侧肌的肌肉活动高于股外侧肌。相反，在得2分的组中，股外侧肌的肌肉活动高于股内侧肌。[结论] 因此，本研究表明，箭步蹲可根据运动能力显示股四头肌活动差异，从而有助于有效增强股四头肌。
