Blood flow restriction endurance exercise and endurance performance in athletes

<p style="text-align: justify;"><br />The development and advancement of sports training over time have been accompanied by continuous innovations, which significantly contribute to improving athletic performance. In this process, research has played a crucial role in understanding the effectiveness of various training methods, including blood flow restriction (BFR) exercise, which is increasingly gaining attention due to its potential to enhance athletic performance. BFR training can be implemented in both: resistance exercise and endurance exercise. The studies discussed indicate a growing interest in the application of BFR through endurance type of exercise to enhance aerobic capacity. <br />This narrative review examined the role of BFR training in enhancing endurance performance by reviewing relevant literature. We performed a comprehensive search on PubMed and Google Scholar using keywords such as “Blood Flow Restriction”, “endurance exercise”, “aerobic capacity”, and “athletes”. The focus was on peer-reviewed articles published in the last decade that investigated the effects of BFR training on endurance and aerobic capacity, specifically within athletic populations. Studies included in this review were selected based on their relevance to BFR training and its impact on endurance performance, while those not directly related to BFR or involving non-athlete populations were excluded. Key findings concerning BFR training protocols and their impact on endurance metrics were summarized. This review aims to provide an overview of the current evidence regarding the effectiveness of BFR training in endurance exercise and its potential implications for optimizing athletic performance. <br />These investigations adopting BFR training show promising results, with several studies reporting significant improvements in key physiological parameters such as maximal oxygen consumption (VO<sub>2</sub> max) and muscular endurance. <br />Overall evidence suggests that integrating BFR training into endurance exercise training regimens holds potential for optimizing aerobic capacity in athletes.</p>
