Table 4. One-way ANOVA of repeated measurements used to compare differences of the normalized values (% of Baseline) among the five normalized rounds of the IFP (1, 2, 3, 4, and 5) and the recovery (Rec).

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