Brief summary: 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.

Detailed description: Blood flow restriction (BFR) training is increasingly used to enhance athletic performance, but its effects on anaerobic fatigue in distance runners remain unclear.
