简要总结
Static passive muscle stretching, performed weekly, can increase muscle flexibility and range of motion. Typically, static stretching is performed either before starting specific exercises or at the end of a workout. However, the effects of static passive stretching when performed during sets are still not entirely clear in terms of performance. This study aims to evaluate the effects of inter-set stretching on muscle performance
详细描述
This project aims to evaluate the potential effects of stretching exercises on muscular performance. In particular, we aim to administer passive static stretching between sets of a bench press performance. Within this project we will carry out a crossover design project in which the participants will be tested for two conditions and one control session. The main protocol consists of performing five sets of bench press at 70% of 1-RM. The 1-RM will be calculated before the start of the data collection procedure, through a standardized and validated approach. The experimental sessions will comprise two interventions. The first intervention will be to administer the stretching protocol to the agonist muscles involved in the bench press performance (pectoralis muscles). While the second intervention will be to administer the stretching protocol to the antagonist muscles involved in the bench press performance (dorsal muscles). Within the control session the participants will not perform any stretching between sets. The three arms will be randomized. As outcome variables, the primary outcome will be the comparison of the total volume across each agonist, antagonist, and control session. The secondary outcomes to be assessed are strength, power, velocity, and volume.
