Beetroot juice supplementation enhances the effects of blood flow restriction training on lower limb strength and vertical jump performance under fatigue in male university students: a randomized, double-blind, placebo-controlled study.

Key Points

• This research aims to evaluate the effects of beetroot juice supplementation on strength and performance during blood flow restriction (BFR) training.
• Conducted a randomized, double-blind, placebo-controlled trial.
• Involved male university students participating in four weeks of BFR training.
• Assessed knee flexor and extensor strength and vertical jump performance.
• Both BFR training and beetroot juice supplementation improved knee strength and vertical jump performance.
• Beetroot juice specifically helped reduce fatigue-related declines in jump performance.
