H = hamstring; Q = quadriceps; 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 quadriceps and hamstring muscle strength was Nm kg−1 × 100.
