As an innovative training method, blood flow restrictive exercise has gradually received extensive attention and application in rehabilitation medicine in recent years. Blood flow restrictive exercise can be combined with low-load, low-intensity training to promote individual muscle hypertrophy and enhance muscle strength to prevent muscle atrophy, which provides an alternative for those who cannot perform high-load, high-intensity training. However, the clinical use strategy and clinical application effect of blood flow restriction exercise are still unclear. This article will mainly introduce the operation methods, use risks, and application methods of blood flow restrictive exercise, in order to provide a reference for the clinical application and research of blood flow restrictive exercise.
