What it’s for
- Selected low-load strength and rehabilitation programmes
Exercise performed with cuffs that partially restrict blood flow to working limbs.
Purpose, evidence and practical considerations.
Low-load BFR can improve strength in some settings. It requires appropriate screening and pressure selection; improvised tight bands do not reproduce a supervised protocol safely.
Confidence: moderate
Cuff pressure, limb size, medical history, and supervision matter. Incorrect use can cause pain, nerve symptoms, bruising, or excessive vascular stress; people with clotting, vascular, cardiovascular, pregnancy, or recent-surgery concerns need clinical screening.
A cuff changes local blood flow and metabolic stress so low-load exercise can stimulate strength and hypertrophy adaptations at loads below conventional resistance training.
