Effects of Blood Flow Restriction Training on Explosive Power in Athletes: A Systematic Review With Meta-Analysis.

Blood flow restriction training, which uses a cuff to partially limit blood flow to a limb during low-load exercise, has been proposed as a way to build strength and power without heavy loading, which matters for athletes managing fatigue or recovering from injury. This review pooled 20 randomized trials involving 362 competitive athletes to see whether the approach actually improves explosive power measures like jumping, sprinting, and changing direction. Overall, the training was linked to a small-to-moderate improvement in explosive power, with benefits also seen for vertical jump, sprint time, change of direction, and mean explosive power individually. The authors also found that more frequent, longer programs and specific cuff pressures seemed to matter, though these programming comparisons come from secondary analyses across a modest number of trials, so they carry more uncertainty than the headline finding.

The review does not report on adverse events or long-term carryover to competition.

If you're an athlete trying to build power while easing up on heavy weights, maybe during a rehab phase, this review looked at whether a specific technique called blood flow restriction training can help. It involves wrapping a cuff around an arm or leg to partially restrict blood flow while performing lower-load exercises. Pulling together 20 small randomized studies involving 362 competitive athletes, the researchers found that this training was linked to a small-to-moderate improvement in explosive power measures, including jump height, sprint speed, and the ability to change direction quickly.

The review also suggested that training more often (three or more times a week) for longer than six weeks, along with adjusting cuff pressure, may matter for different outcomes, though this part of the analysis is less certain and based on fewer studies. This is encouraging but still limited evidence. The review does not say whether the training is safe over longer periods, and these are performance measures in a lab or training setting, not direct evidence about injury recovery or competition outcomes.

For clinicians weighing low-load training strategies during rehabilitation or load management phases, this meta-analysis addresses whether blood flow restriction training can meaningfully improve explosive power outputs in competitive athletes. Pooling 20 randomized trials and 362 athletes using 2- or 3-level random-effects models to account for multiple correlated outcomes, the authors report a small-to-moderate overall effect (SMD = 0.46) on explosive performance, with significant individual effects for vertical jump (SMD = 0.52), 30-meter sprint (SMD = -0.52), change of direction (SMD = -0.46), and mean explosive power (SMD = 0.54). Moderator analyses indicate that training frequency of three or more sessions weekly for over six weeks, and cuff pressures above 150 mmHg for power-based outcomes versus 150 mmHg or below for change of direction and standing long jump, were associated with stronger effects.

These are subgroup findings resting on a smaller subset of the included trials, so they should be interpreted as hypothesis-generating rather than firmly established dosing rules. The review does not report adverse events, risk-of-bias ratings, or heterogeneity statistics in the abstract, and it does not establish whether these performance gains translate into reduced injury risk or improved competitive outcomes, limiting how far these findings can inform programming decisions beyond the explosive-power metrics studied.
