High-Load Blood Flow Restriction (BFR) Training May Decrease Anaerobic Fatigue in Distance Runners

Gulhane Training and Research Hospital42 enrolled

Overview

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.

Outcomes

Primary Outcomes

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.

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.
