Table 3. One-way ANOVA of repeated measurements used to compare differences of the raw values among the seven occasions: Baseline (B), five normalized round of the IFP (1, 2, 3, 4, and 5) and the recovery (Rec).

The variables used for comparison were: Area, RPD and estimated force at the times of 30 ms, 50ms, 100ms, 500 ms, 1 s and 2 s from the onset of the muscular contraction.
