Blood Flow Restriction and Recovery in Soccer Players

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.

Treatment and study plan

Blood flow restriction recovery

Device

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.

Active Recovery

Other

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.

  3. Change from Baseline in Muscle Soreness

    Time frame: Change from Baseline in Muscle Soreness at 0 hours, 24 hours, 48 hours, 72 hours and 4 weeks

    Muscle Soreness measured by a Wellness Questionary (1=Very sore; 2= Increase in soreness/ tightness; 3=Normal; 4=Feeling good; 5=Feeling great)

  4. Change from Baseline in Sleep Quality

    Time frame: Change from Baseline in Sleep Quality at 0 hours, 24 hours, 48 hours, 72 hours and 4 weeks

    Sleep Quality measured by a Wellness Questionary (1=Insomnia; 2=Restless sleep; 3=Difficulty falling asleep; 4=good; 5=Very restful)

  5. Change from Baseline in Stress

  6. Change from Baseline in Mood

    Time frame: Change from Baseline in Stress at 0 hours, 24 hours, 48 hours, 72 hours and 4 weeks

    Mood measured by a Wellness Questionary (1=Highly annoyed / irritable / down; 2=Snappy with team-mates, family and friends; 3=Less interested in others / activities; 4=Generally good mood; 5=Very positive mood)
