Abstract

Blood flow restriction exercise is a training method that partially restricts arterial flow and total venous flow in skeletal musculature during exercise. The study aims to demonstrate the physiological cardiovascular effects generated by exercise with blood flow restriction, as well as to point out evidence about the safety in the application of the method. Exercise with blood flow restriction is capable of causing beneficial physiological changes in the cardiovascular system and seems to be a safe method of application together with physical exercise, however standardization measures of the method need to be better studied with regard to individuals with cardiovascular changes.

Highlights

  • The performance of exercises with reduced blood flow obtained by restricting vascularization proximal to the muscle developed by Dr Yoshiaki Sato in Japan, was initially known as “kaatsu training”

  • Standardization measures on cuff occlusion pressure, timing and revascularization need to be further studied with regard to individuals with cardiovascular alterations

Summary

Introduction

The performance of exercises with reduced blood flow obtained by restricting vascularization proximal to the muscle developed by Dr Yoshiaki Sato in Japan, was initially known as “kaatsu training”. A tourniquet cuff is required in the proximal regions of the limb, which, when inflated, generates a gradual mechanical vascular compression under the cuff, resulting in partial restriction of arterial and venous blood flow to structures distal to the cuff. This method is generally used for hypertrophy and increased muscle strength, the method is capable of generating systemic physiological effects through hypoxia generated in the muscle environment, which can be observed in addition to the musculoskeletal system [1,2]
