Influence of blood flow restriction training on aerobic performance and fatigue resistance in athletes

Abstract

Blood Flow Restriction Training (BFRT) has emerged as an innovative conditioning strategy that allows athletes to achieve muscular and cardiovascular adaptations at significantly lower intensities than traditional training. While its efficacy in enhancing muscular hypertrophy and strength is well documented, recent research highlights its potential benefits in improving aerobic performance and fatigue resistance. This review synthesizes current evidence on the physiological mechanisms, training protocols, and outcomes associated with BFRT in endurance and team-sport athletes. Findings indicate that BFRT can enhance oxygen utilization efficiency, stimulate angiogenesis, and elevate aerobic capacity even at submaximal intensities. Moreover, adaptations in muscle oxidative capacity, mitochondrial biogenesis, and lactate tolerance contribute to delayed onset of fatigue. Despite promising results, methodological variability across studies and limited long-term data warrant further research to standardize protocols and optimize training outcomes.
