Abstract

This study aimed to investigate the acute effect of static stretching (SS) and proprioceptive neuromuscular facilitation (PNF) in the performance of repetition maximum (RM) during a training session of force (TSF) for upper and lower limbs. Six sessions were conducted during the experiment period. At the first three sessions, a stretching protocol familiarization was adopted followed by 12 maximal repetitions test and retest. From the fourth session on, the following experimental protocols were applied: a) Static stretching + TSF; b) PNF stretching + TSF; c) specific warm-up with 20 repetitions (30% of 12 RM load) + TSF. The sessions included three sets of 12 RM for each exercise (leg press 45º, leg extension, leg curl and plantar flexion). It was observed significant differences (p< .05) between the stretching methods to the sum of (RM) of the three sets in leg press 45º, leg extension and leg curl. It was observed significant difference (p< .05) in the SRM on the three of four exercises at the EP vs. SS and PNF vs. SS situations. Both stretching methods decrease the subsequent strength performance, reducing its levels. Therefore, PNF and SS methods should not be recommended before a training session of force.
