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.

Measure	Time frame	Description
The effects of an isokinetic training program combined with blood flow restriction (BFR) on anaerobic performance and fatigue resistance in long-distance runners were investigated.	baseline and week 8	Lower extremity Wingate Test (WanT) was used to evaluate the anaerobic capacities of long-distance runners. In calculating the fatigue index; (peak power - minimum power/peak power) x 100 (% fatigue index) formula was used.
