BFR Training on Muscle Morphology

Официальное название

Effectiveness of Blood Flow Restriction Training on Muscle Morphology and Prevention of Patellofemoral Pain Syndrome and Anterior Cruciate Ligament Injury

Обзор

This randomized clinical trial study compares high-load eccentric training (HL-Et), sham LL-BFRt, and low-load blood flow restriction (LL-BFRt) in sportsmen. The primary inquiries it seeks to address are: Is LL-BFR superior to HL-Et and sham LL-BFRt in terms of improving muscle morphology? Is LL-BFR a more effective Patellofemoral Pain Syndrome and ACL injury preventive than HL-Et and sham LL-BFRt? The three intervention groups that will be randomly assigned to participants are LL-BFRt, sham LL-BFRt, and HL-Et. Participants are expected to carry out: Participants in LL-BFRt will be required to perform LL eccentric training at 30% of their repetition maximum (RM) and 70% of their artery occlusion pressure (AOP). This training will include stairs, single leg squat, and single leg deadlift. Participants in HL-Et will be required to perform LL eccentric training at 70% of their maximum number of repetitions (RM). In order to determine whether muscular morphology and the prevention of Patellofemoral Pain Syndrome and ACL injury improve following the interventions and follow-up, researchers will compare LL-BFRt, sham LL-BFRt, and HL-Et.

Вмешательства

• Процедура Low load-BFRt
  The participants' two legs will be subjected to 70% arterial occlusion pressure when the physical therapist applies the BFR cuffs. After that, participants will be required to complete eccentric exercises with a maximum repetition count of 30%, such as stairs, single leg squat, and single leg deadlift.
• Процедура Sham Low load-BFRt
  The participants' two legs will be subjected to 10% arterial occlusion pressure when the physical therapist applies the BFR cuffs. After that, participants will be required to complete eccentric exercises with a maximum repetition count of 30%, such as stairs, single leg squat, and single leg deadlift.
• Процедура High load-Eccentric training
  The physical therapist will instruct the participants to complete eccentric exercises at a maximum of 70% repetitions, such as stairs, single leg squat, and single leg deadlift.
