This study investigates the effects of high-load BFR training on anaerobic performance and fatigue resistance in distance runners. To determine whether adding BFR to isokinetic resistance training improves anaerobic performance and 5-10 km running times in runners. Forty-two runners were randomized into BFR (n=21) and control (n=21) groups. Both groups followed an identical 8-week isokinetic training protocol twice weekly. The BFR group performed exercises with arterial occlusion pressure set to 80% of the measured occlusion pressure. Anaerobic performance was assessed via the Wingate test, and 5 km and 10 km running times were recorded before and after the intervention. Statistical analyses compared pre- and post-training performance within and between groups.

Blood flow restriction (BFR) training is increasingly used to enhance athletic performance, but its effects on anaerobic fatigue in distance runners remain unclear. This study investigates the effects of high-load BFR training on anaerobic performance and fatigue resistance in distance runners.To determine whether adding BFR to isokinetic resistance training improves anaerobic performance and 5-10 km running times in runners.
