About this study
Official title: High-Load Blood Flow Restriction (BFR) Training May Decrease Anaerobic Fatigue in Distance Runners: A Randomized Controlled Trial
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: baseline and week 8

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2025; AzTrials last refreshed its copy on 27 Oct 2026.
