Effects of blood flow restriction training and aerobic exercise on energy expenditure in young men

• Blood flow restriction combined with low-intensity aerobic exercise significantly increases total energy expenditure compared to low-intensity aerobic exercise alone. • The combination does not significantly alter the proportional contribution of aerobic, anaerobic lactic, and anaerobic alactic energy systems. • Blood flow restriction training significantly increases excess post-exercise oxygen consumption during the 40-minute recovery period. • The intervention does not increase subjective ratings of perceived exertion, but heart rate is elevated at 1 minute post-exercise, warranting caution.
