Table 1. Test-retest reliability for dependent variables.
The intraclass correlation coefficient (model “3,1”) (ICC (3, 1)), standard error of measurement (SEM), and coefficient of variation (CV) of variable measurements (the contralateral hip flexion passive range of motion [ROM], the contralateral biceps femoris [BF] and semitendinosus [SEMI] EMG amplitude, the contralateral knee flexion isometric strength, and the rate of force development (RFD) for the first 50 [RFD0−50], 100 [RFD0−100], and 200 [RFD0−200] ms of the maximal isometric contraction).
| Variable measures | ICC (3,1) | SEM | CV (SEM %) |
|---|---|---|---|
| Passive ROM (°) | 0.91 | 4.26 | 6.2% |
| Isometric strength (N) | 0.88 | 34.27 | 10.6% |
| EMG Amplitude of BF (µV) | 0.84 | 31.76 | 23.8% |
| EMG Amplitude of SEMI (µV) | 0.80 | 38.55 | 30.2% |
| RFD0−50(N/s) | 0.81 | 633.00 | 37.9% |
| RFD0−100(N/s) | 0.84 | 312.39 | 23.5% |
| RFD0−200(N/s) | 0.87 | 184.06 | 17.2% |
