High-load, low-load, and passive blood flow restriction training for competitive sprinters
Comparative Effects of High-Load, Low-Load, and Passive Blood Flow Restriction Training on Strength and Sprint Performance in Competitive Sprinters
NA · Riphah International University · NCT07438535
This study will test whether high-load, low-load, or passive blood flow restriction training improves sprint speed and strength in competitive sprinters aged 16–30.

What this trial studies
This randomized trial will assign competitive male and female sprinters aged 16–30 to one of three groups: high-load BFR (70–85% 1RM during sets), low-load BFR (20–30% 1RM during sets), or passive BFR applied between sets. Participants complete a six-week, sprint-specific resistance program three times per week including resisted sprints, barbell step-ups, hip thrusts, Nordic curls, and bounding. Primary outcomes are 1RM strength, countermovement and standing broad jump performance, and timed 10m/30m/100m sprints, with subjective exertion tracked by sRPE; measurements are taken before and after the intervention. The trial is conducted at the Punjab Sports Board in Lahore using purposive sampling of competitive sprinters.
Who should consider this trial
Good fit: Ideal candidates are healthy competitive sprinters aged 16–30 with at least two years of sprint-specific training and no contraindicating medical conditions.
Not a fit: Individuals with cardiovascular, vascular, pulmonary, renal, or other contraindicating medical conditions, pregnant or lactating people, or athletes not engaged in sprint training are unlikely to receive benefit from participation.
Why it matters
Potential benefit: If successful, one of the protocols could offer a faster or lower-load way to boost sprint speed and neuromuscular strength for sprinters.
How similar studies have performed: Prior trials and meta-analyses of BFR training report small-to-moderate improvements in jump, sprint, and power outcomes, so this approach has supporting but not conclusive evidence.
