- What it is
- Exercise done with a cuff or band that partly restricts blood flow to the working limb; also applied passively. Marketed for strength and muscle size with lighter loads, and for limiting muscle loss when normal training is not possible.
- What the evidence shows
- Researcher-authored practitioner guidelines (Frontiers in Physiology, 2019) cover methods, application and safety for strength, hypertrophy and passive use against atrophy. No trial counts are cited here. Grade B · Some human trials — limited, mixed, or in a narrow clinical population
- Regulatory status
- A training method rather than a regulated product. No regulatory approval was verified for this use.
- Anti-doping status, 2026 List
- Not prohibited. Not named on the 2026 Prohibited List.
- What can go wrong
- The guideline paper states that the literature reveals minimal adverse events pertaining to venous thromboembolism and no clinically reported events. D-dimer and CRP rose but stayed in the clinically normal range.
