Comparison between Warm-Up Protocols in Post-Activation Potentiation Enhancement (PAPE) of Sprint and Vertical Jump Performance in a Female Futsal Team.

The aim of this study was to examine the influence of three warm-up protocols, with and without post-activation performance enhancement (PAPE), on sprint and vertical jump performance in female athletes. Twenty-five university futsal athletes were randomly assigned to three protocols: i) Traditional Warm-Up (TWU), involving cardiovascular, coordination exercises, and dynamic stretching; ii) Drop Jump Warm-Up (DJWU), consisting of drop jumps from heights of 30 and 40 cm; and iii) Maximum Isometric Warm-Up (MIWU), with high-intensity isometric contractions held for 10 seconds in a squat position at approximately 130-135 degrees of knee flexion. Tests included the countermovement vertical jump (CMVJ) and a 20-meter sprint (S20).

The purpose of this study was to investigate the acute effects of multi-joint resistance exercises (MJRE) with blood flow restriction on hormonal responses. Ten men participated in the study and underwent two experimental protocols in random order: four sets (30, 15, 15, and 15 reps, respectively) of MJRE (half squat and horizontal chest press) were performed with 20% of 1RM and a rest time between sets of 30 s, combined with intermittent blood flow restriction (LI + BFR protocol); and four sets (8, 8, 8, 20 reps, respectively) of the same MJRE performed with 75% of 1RM load (HI protocol), with a 90 s rest between the first three sets and 30 s between the third to the fourth set. Blood samples were collected before (PRE), immediately after (POST), and 15 min after the performance of MJRE (POST15).
