This study aimed to examine the effect of applying BFR during rest periods repeated cycling sprints on muscle oxygenation.Seven active males performed 5 × 10-s maximal pedaling efforts with 40-s passive rest, or without application period. was applied for 30 s between (between and 35 into rest) through a pneumatic pressure cuff inflated at 140 mmHg. Vastus lateralis oxygenation monitored using near-infrared spectroscopy. In addition, blood lactate concentration heart rate were also evaluated.The trial showed significantly lower oxyhemoglobin (oxy-Hb) tissue saturation (StO2) levels than CON (P < 0.05). However, power output did not differ two trials > 0.05).Applying decreased musculature, interfering sprints.
