Comparative Effects of Blood Flow Restriction Resistance Training Versus Blood Flow Restriction Cycling on Pain, Quadriceps Strength, and Functional Outcomes in Athletes With Patellofemoral Pain (BFR-PFP-RCT)
Comparative Effects of Blood Flow Restriction Resistance Training Versus Blood Flow Restriction Cycling on Pain, Quadriceps Strength, and Functional Outcomes in Athletes With Patellofemoral Pain: A Randomized Controlled Trial

정황
상세 설명
Patellofemoral pain (PFP) is among the most prevalent musculoskeletal conditions in athletes, with reported prevalence of 30-40% in sports populations. High-load resistance training is the conventional rehabilitation approach but often exacerbates joint stress and reduces adherence. Blood flow restriction (BFR) training enables strength gains at low loads by applying a pneumatic cuff at 80% LOP on the proximal thigh.
This trial compares two BFR modalities:
- Group A (BFR-RT): Leg press and seated knee extension, 1x30 + 3x15 reps at 30% 1RM, 3x/week for 8 weeks.
- Group B (BFR-CYC): Stationary cycling at low resistance, 4x5-minute intervals at 70-80 RPM (RPE 11-13), 3x/week for 8 weeks.
All sessions are supervised one-on-one by a physiotherapist. Assessments are conducted at baseline and week 8. The study is single-blinded (outcome assessor blinded). Randomization via computer-generated sequence. Statistical analysis via SPSS v27 (paired t-test / Wilcoxon for within-group; independent t-test / Mann-Whitney for between-group, alpha=0.05).

활성 비교기: BFR Resistance Training Group
Participants perform leg press and seated knee extension exercises at 30% of 1RM with a pneumatic cuff (12 cm wide, Delfi Medical) applied to the proximal thigh at 80% limb occlusion pressure (LOP).
Protocol: 1 set of 30 + 3 sets of 15 repetitions, with 60-second rest between sets (cuff deflated).
Frequency: 3 sessions/week for 8 weeks (24 sessions total).
1RM re-estimated every 2 weeks for progressive load adjustment.
Warm-up: 10 min low-resistance cycling (no BFR).
Cool-down: 5 min lower-limb stretching.
|
Participants will undergo blood flow restriction (BFR) resistance training using a pneumatic cuff applied to the proximal thigh at 80% limb occlusion pressure.
Exercises include leg press and seated knee extension performed at 30% of one-repetition maximum (1RM).
Training will be conducted for 8 weeks, with supervised sessions 3 times per week.
Cuff pressure will be monitored and adjusted using BP cuff.
The aim is to improve quadriceps strength and reduce pain in patients with patellofemoral pain.

실험적: BFR Cycling Group
Participants perform stationary cycling at low resistance targeting RPE 11-13, with a pneumatic cuff (12 cm wide, Delfi Medical) applied to the proximal thigh at 80% LOP.
Protocol: 4 x 5-minute cycling intervals at 70-80 RPM, with 1-minute rest between intervals (cuff deflated).
Frequency: 3 sessions/week for 8 weeks (24 sessions total).
Cadence increased by 5 RPM if RPE <11.
Warm-up: 10 min low-resistance cycling (no BFR).
Cool-down: 5 min lower-limb stretching.
|
Participants will perform stationary cycling combined with blood flow restriction (BFR) applied to the proximal thigh at 80% limb occlusion pressure.
Cycling will be performed at low resistance with controlled cadence for 8 weeks, 3 sessions per week under physiotherapist supervision.
The protocol includes structured cycling intervals with rest periods and continuous monitoring of pain and perceived exertion.
The intervention aims to improve quadriceps strength, reduce pain, and enhance functional outcomes in patients with patellofemoral pain.
