H = hamstring; Q = quadriceps; AT = acceleration time; OSI = overall stability index; CI = confidence interval. Time 0 × 1, p value between time 0 and 1; Time 0 × 2, p value between time 0 and 2; Time 1 × 2, p value between time 1 and 2. Note: The values expressed as mean ± standard deviation, measurement unit of acceleration time: millisecond (msec), measurement unit of postural stability: degree (°).
