Table 1.
Mean (SD), change scores, p-values, and Cohen’s d effect size values for muscle function variables before (Pre) and after (Post) the training period.
| Action | Variable | Pre | Post | Change Score (%) | p-Value | Cohen’s d |
|---|---|---|---|---|---|---|
| Eccentron | Peak Force (N) | 1364.58 (599.23) | 1882.28 (600.58) | 37.94 | p < 0.001 | 0.86 |
| Leg Press | 1 RM (N) | 1909.31 (730.12) | 2272.01 (793.18) | 19.00 | p < 0.001 | 0.48 |
| Knee Extensors (Biodex) | IsomPT (Nm) | 171.19 (42.30) | 182.16 (33.65) | 6.41 | p = 0.16 | 0.29 |
| Ecc30 (Nm) | 216.65 (59.89) | 227.14 (44.29) | 4.85 | p = 0.33 | 0.20 | |
| Con150 (Nm) | 128.47 (40.73) | 130.08 (37.66) | 1.25 | p = 0.81 | 0.04 |
Note: Cohen’s d values compare within-group pretest and posttest differences and are identified as being small, moderate, and large on the basis of values of 0.2, 0.5, or 0.8 respectively. Ecc30 = Biodex knee extensor eccentric muscle action at 30°·sec−1; Eccentron = maximal multiple-joint eccentric force on the Eccentron device; IsomPT = isometric PT of the knee extensors on the Biodex; Con150, Biodex knee extensor concentric muscle action at 150°·sec·−1.
