Details and patient eligibility

About

This study will randomize healthy adults who regularly perform resistance training exercises for the lower extremities (2x a week) to one of three groups: a blood flow restriction (BFR) exercise group that trains 2x a week, a BFR exercise group that trains 5x a week, and a control group that does not perform any additional BFR exercise. Those randomized to the BFR groups will perform the unilateral 90-0 knee extension exercise followed by the bilateral squat. Subjects will have the BFR applied to their dominant lower extremity and will perform 4 sets (30/15/15/15 reps) per exercise. Training will initial start at 30% of 1RM with training intensity increased by 5% every 2 weeks. The training program will last 8 weeks.

Pre- and posttests include ultrasound imaging of the dominant leg rectus femoris and strength testing via hand held dynamometry.

55 participants in 3 patient groups

5x a week BFR training group

Experimental group

Description:

Subjects will perform 2 exercises (LAQ and squat) with BFR applied to dominant thigh daily (5x/wk). Exercises performed for 4 sets (30/15/15/15 reps) initially at 30% 1RM; with load increased by 5% every 2 weeks. Training program lasts for 8 weeks. They are also to continue with their regular independent exercise program.

Other: 5x a week BFR training group

2x a week BFR training group

Experimental group

Description:

Subjects will perform 2 exercises (LAQ and squat) with BFR applied to dominant thigh twice a week (2x/wk). Exercises performed for 4 sets (30/15/15/15 reps) initially at 30% 1RM; with load increased by 5% every 2 weeks. Training program lasts for 8 weeks. They are also to continue with their regular independent exercise program.

Treatment:

Other: 2x a week BFR training group

Control group

No Intervention group

Description:
