Clinical Trial Summary

The objective is to evaluate the effects of blood flow restriction training on the post-competition recovery of professional and semi-professional soccer players. Randomized crossover clinical trial, with two intervention groups: Experimental group I will carry out a recovery training based on the use of the blood flow restriction (BFR) on day 1 post-competition. On the other hand, the Experimental II group will perform the same recovery training without the use of BFR. After 1 month the groups will cross their intervention and make the recovery with the opposite method to the initial one. The study will be carried out during the 2021-2022 season, from first regional to third division of Spanish soccer, with soccer teams from the Mallorca Island. Before the competition, the countermovement jump (CMJ) will be evaluated and repeated at 0, 24, and 72 h after the competition. The levels of muscle soreness (DOMS) will be evaluated pre-post-competition 0, 24, 48 and 72h later. The same procedure will be carried out to evaluate muscle fatigue, sleep quality, and stress through a questionnaire that athletes will fill out pre, 0, 24, 48 and 72h after the game. Sociodemographic and anthropometric data will be collected before starting the study.

Description:

W-UP: The warm-up will consist of 5 minutes running slow, 5 minutes mobility, and 5 minutes of running exercises. In addition, the warm-up will contain a familiarization with the jump test.

Intervention

Device:
• Blood flow restriction recovery
Soccer players included in experimental group I will carry out this program for 1 week setting the blood pressure to ~ 60% of limb occlusion pressure (LOP). After a month they will carry out the program without restriction of blood flow. Which will consist of a warm-up part with continuous running (5 min), 6 sprints from box to box of the field at 60-70% of a maximum repetition, and an activation part in the form of rounds with the ball.

Other:
• Active recovery
Soccer players included in experimental group II will carry out this program for 1 week. After a month they will carry out the program with blood flow restriction. Which will consist of a warm-up part with continuous running (5 min), 6 sprints from box to box of the field at 60-70% of a maximum repetition, and an activation part in the form of rounds with the ball.
