BFR Training on Muscle Morphology
Sponsor: Udayana University
Summary
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.

Conditions
Interventions
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.
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.
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.
