Key result
Blood flow restriction exercise promotes muscle hypertrophy and cardiovascular improvements by selectively blocking venous flow.
Why the study?
To establish the concept of blood flow restriction exercise by integrating literature across sports, recreation, and rehabilitation, and providing evidence-based information on its principles, mechanisms, and precautions.
This review provides a comprehensive overview of the physiological mechanisms, applications, and precautions of blood flow restriction exercise.
Synthesizes BFR mechanisms and applications; leaves open its role in cardiovascular rehabilitation pending controlled trials.
This review paper outlines the effect of blood flow restriction exercise on hemodynamics from the biomechanical perspective. Blood flow restriction exercise is a kind of exercise methods that maximizes the effectiveness of exercise by applying specific pressure to block vein flow while allowing flow of arteries by wearing portable pneumatic cuffs in the upper and lower parts of the body prior to exercise. In various existing literature, the effect of blood flow restriction on exercise has been revealed based on lots of field including elite sports, recreation, and rehabilitation. This study will establish the concept of blood flow restriction on exercise by integrating the contents of such research. Therefore, the purpose of this study is to provide information based on scientific evidence on blood flow restriction exercise by introducing the concept and principle of blood flow restriction, physiological mechanisms and effects, actual application cases, and precautions.
