Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Evidence regarding the effectiveness of blood flow restriction during isokinetic exercises is insufficient. When the literature is reviewed, it is seen that there are very few studies investigating the effect of isokinetic training program with blood flow restriction on muscle strength and endurance in healthy athletes. In line with this information, the aim of this study was to investigate the effect of an 8-week isokinetic training program combined with blood flow restriction on knee flexor and extensor maximal muscle strength and endurance in runners.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to investigate the effect of lower extremity isokinetic training combined with blood flow restriction (BFR) on knee flexor and extensor muscle strength and endurance in runners. A total of 42 runners were randomly assigned to either the isokinetic training group with blood flow restriction (BFR Group; n= 21) or the isokinetic training group without blood flow restriction (Control Group; n= 21). For the BFR, the occlusion pressure was set to 80% of arterial occlusion pressure as determined. The isokinetic training protocol for the knee flexor and extensor muscles consisted of 3 sets of 10 repetitions in 60°/sec and 3 sets of 30 repetitions in 180°/sec for 8 weeks, 2 times per week for 16 sessions. The muscle strength and endurance were evaluated before and after the training program using an isokinetic dynamometer.
