|---|---|---|---|---|---|
| Leg Press 5RM (kg) | 164.61 ± 54.35 | 201.62 ± 67.50 * | <0.001 | +22.7% | −0.60 |
| Bench Press 5RM (kg) | 39.12 ± 20.15 | 46.43 ± 21.18 * | <0.001 | +18.6% | −0.35 |

Note. All values are presented as means ± standard deviation; 5RM = five repetition maximum; Δ = ([posttest score − pretest score]/pretest score) × 100; d = (pretest score − posttest score)/pooled standard deviation; * = significantly greater than pretest score (p < 0.05).
