简要总结
The purpose of this research is to determine the effects of low-load blood flow restriction (BFR) training compared to conventional strengthening using dynamic force plate and isometric force frame analyses in healthy subjects.
详细描述
The purpose of this research is to determine the effects of low-load blood flow restriction (BFR) training compared to conventional strengthening using dynamic force plate and isometric force frame analyses in healthy subjects. The primary research procedures are:
Subjects will be randomized into either BFR or conventional strengthening groups.
BFR and conventional strengthening programs will be implemented. Force plate and force frame data will be collected at baseline, 4, 6, 8, 12, and 16 weeks.
Subject Population. The study will enroll 18 healthy volunteers. The study includes 6 visits.
The total study duration for each subject is 16 weeks.

研究组 & 干预措施
Group 1 - Standard strengthening group (no BFR)
Participants will warm up on a stationary bike for 5 minutes
The program will consist of the following exercises using a 30,15,15,15 rep scheme:
Banded squats Step ups (8 inch) Romanian dead lifts (RDL)
干预措施: Stanard strengthening program. (Other)
Group 2 - Low-load BFR group
Participants will warm up on a stationary bike for 5 minutes BFR will be applied to non-dominant limb (dominant limb is determined as the preferred leg for kicking a ball)
The program will consist of the following exercises using a 30,15,15,15 rep scheme:
Banded squats Step ups (8 inch) Romanian dead lifts (RDL)
干预措施: BFR (Device)
