Study Details

Study Description

Brief Summary

The aim is to evaluate the effects of aerobic blood flow restriction on academy football players. Randomized clinical trial, with two intervention groups: Experimental group I will carry out training based on running on the treadmill using blood flow restriction (BFR) on match days 4 and 3 pre-competition (MD-4, MD-3). On the other hand, the Experimental II group will perform the same training without the use of BFR for 6 weeks. The study will be carried out during the 2023-2024 season in the National and Youth Honor Divisions of Spanish soccer, with soccer teams from Mallorca Island. Before and after 6 weeks of intervention, the countermovement jump (CMJ), maximum aerobic speed (MAS), VO2max, and repeat sprint ability will be evaluated. The levels of muscle soreness (DOMS) will be evaluated at MD-4, MD-3, and MD-2. The same procedure will be carried out to evaluate muscle fatigue, sleep quality, and stress through a questionnaire. Sociodemographic and anthropometric data will be collected before starting the study. In addition, the rate of exertion perceived will be evaluated at MD-4, MD-3, and MD-2.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Blood flow restriction (Experimental I) Running with Blood Flow Restriction on the treadmill for 4 sets of 5 minutes,1'30" interset rest using a periodization methodology in soccer (Match Day 4 and Match Day 3).	Device: Blood flow restriction Running on Treadmill Soccer players included in experimental group I will carry out this program for 6 weeks, setting the blood pressure to ~ 60% of limb occlusion pressure (AOP). They will run for 4 sets of 5 minutes, separated by 1 minute and 30 seconds of rest, at 45-55% of their maximum Aerobic Speed.
Experimental: Non-Blood flow restriction (Experimental II) Running without Blood Flow Restriction on the treadmill for 4 sets of 5 minutes,1'30" interset rest using a periodization methodology in soccer (Match Day 4 and Match Day 3).	Other: Running on Treadmill Soccer players included in experimental group II will carry out the program for 6 weeks without occlude the blood pressure. They will run for 4 sets of 5 minutes, separated by 1 minute and 30 seconds of rest, at 45-55% of their maximum Aerobic Speed.
