One-repetition maximum test results. The session 1-RM values are presented as mean ± standard deviation.
| Exercise | First session (kg) | Second session (kg) | Mean session difference (kg) (95% CI) | T-test results | ICC (95% CI) | SEM |
|---|---|---|---|---|---|---|
| Knee extension | 63.7 ± 28.1 | 67.7 ± 29.7 | 4.0 (1.9–6.2) | P < 0.001 | .96 (.93–.97) | 5.7 kg |
| Knee flexion | 27.0 ± 12.7 | 29.4 ± 13.0 | 2.4 (0.2–4.7) | P = 0.042 | .91 (.79–.96) | 3.8 kg |
| Biceps curl | 43.9 ± 15.6 | 46.6 ± 17.6 | 2.7 (1.2–4.1) | P = 0.001 | .97 (.92–.98) | 2.8 kg |
| Chest press | 57.8 ± 20.6 | 60.1 ± 20.8 | 2.3 (−0.2–4.7) | P = 0.066 | .95 (.90–.98) | 4.3 kg |
ICC: Intraclass Correlation Coefficient. SEM: Standard Error of Measurement which was calculated as: SEM: SDbaseline∗√(1 − r test–retest).
