Overview
Brief Summary
The goal of this randomized clinical trial study is to compare low-load blood flow restriction (LL-BFRt), sham LL-BFRt, and high-load eccentric training (HL-Et) in healthy level 1 sportsman. The main questions it aims to answer are:
- Does LL-BFR improve muscle strength better than sham LL-BFRt and HL-Et?
- Does LL-BFR improve dynamic stability better than sham LL-BFRt and HL-Et?
- Does LL-BFR prevent ACL injury better than sham LL-BFRt and HL-Et?
Participants will be randomized into three intervention groups: LL-BFRt, sham LL-BFRt, and HL-Et. Participants will be asked to do:
- In LL-BFRt, participants will be asked to do LL eccentric training (including double leg squats, split squats, deadlifts, and monster walks) with a 30% of repetition maximum (RM) and 70% of arterial occlusion pressure (AOP).
- In sham LL-BFRt, participants will be asked to do LL eccentric training with a 30% of repetition maximum (RM) and 10% of arterial occlusion pressure (AOP).
- In HL-Et, participants will be asked to do LL eccentric training with a 70% of repetition maximum (RM).
Researchers will compare LL-BFRt, sham LL-BFRt, and HL-Et to see if muscle strength, dynamic stability, and ACL injury prevention improve after the interventions and follow-up.
Detailed Description
Participants will be asked to do five sets of ten repetitions of each eccentric training, one-minute rest interval for each eccentric training and two mins rest interval between each set.
