Abstract
[Purpose] To clarify the factors affecting the ability of healthy young athletes to perform a single-leg sit-to-stand. [Subjects and Methods] The subjects were 78 dominant feet of 78 high school soccer players with no impairment at measurement. The measurement items were single-leg sit-to-stand from seat heights of 40, 30, 20, and 10 cm, single-leg triple-hop test distance, the inclination angle of the lower leg, and single-leg stance duration with closed eyes. [Results] Subjects who could stand up from 10-cm high seats had larger inclination angles of the lower leg, and could hold a single-leg stance with closed eyes longer than subjects who couldn’t. [Conclusion] It is important to consider not only the muscular strength of the legs, but also the ankle flexibility and postural control ability of subjects who can’t perform single-leg sit-to-stand.
