title: Examining differences between center of pressure sway in one-legged and two-legged stances for soccer players and typical adults.
abstract: To examine stance during the measurement of balance ability, this study aimed to clarify the differences and relationships between balance ability in one-legged (dominant or nondominant leg) and two-legged stances in 25 typical male adults and 25 male soccer players. Balance ability was evaluated with four sway factors: sway velocity, anterior-posterior sway, lateral sway, and high-frequency sway factors. The one-legged stance was more unstable than the two-legged stance, the balance abilities related to two-legged and one-legged stances differed, and the balance abilities related to dominant-legged and nondominant-legged stances were similar. The one-legged stance, which was difficult to maintain stably, may be useful in the measurement of static balance ability in young people.
