Effect of Blood Flow Restriction on Football-Related Performance Parameters

January 20, 2024 updated by: Begum Kara Kaya, Biruni University

Improvement of Football-Related Performance Parameters: Application of Blood Flow Restrictive Exercise

The blood flow restriction method can have similar or superior effects to high-intensity exercises even in a short duration, which can positively affect some performance parameters, can be applied with low-intensity load and cause hypertrophy in the muscle by providing high metabolic stress, facilitating muscle growth without significantly changing the total training dose. The aim of this study is to investigate whether adding the blood flow restriction method to the classical training program can be more effective than the classical training applied alone in the development of football-related performance parameters.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 30 years (Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Being a male between the ages of 18-30 years
  • Volunteer to participate in the study
  • Playing football in one of the clubs in Istanbul for at least 1 year
  • Being in the pre-season of the club
  • Absence of any ongoing musculoskeletal problems that limit exercising

Exclusion Criteria:

  • Having at least one of the contraindications preventing the application of blood flow restriction (Smoking, previous venous thromboembolism, risk of peripheral vascular disease (ankle-brachial index <0.9), coronary heart disease, hypertension, hemophilia, etc.).
  • History of sports injury in the last 6 months
  • Orthopedic lower extremity surgery in the last 1 year

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Blood Flow Restriction + Classical Training
Other: Blood Flow Restriction
Blood flow restriction with low load (30-50% 1RM) for 2 sessions in a week for 6 weeks during classical training will be applied.
Experimental: Classical Training Alone
Other: Classical Training Alone
Classical training same as Group 1with moderate to high load (70-90% 1RM) for 2 sessions in a week for 6 weeks will be applied without blood restriction.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Evaluation of Muscle Strength and Endurance
Time Frame: 6 weeks
Isokinetic dynamometer
6 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Evaluation of Lower Extremity Power
Time Frame: 6 weeks
Vertical jump test

Evaluation of Aerobic Endurance
Time Frame: 6 weeks
Yo-Yo Intermittent Recovery Level 1 test

Evaluation of General Satisfaction and Perceived Performance Change
Time Frame: 6th week
General satisfaction and the change in performance perceived by the participants will be evaluated with the 7 points Global Rating of Change Scale after the training program. According to the scale, it is expressed as "-3: I am much worse, -2: I am worse, -1: I am a little worse, 0: No change, 1: I am a little better, 2: I am better, 3: I am much better".
