KAATSU training, defined as low-intensity resistance exercise combined with restricted venous blood flow via proximal limb compression, increases muscle mass and strength in healthy individuals and patients.

KAATSU training involves wearing a specialized cuff on your upper arms or thighs while performing low-intensity resistance exercises. The cuff restricts venous return to create a 'pump' without cutting off arterial blood flow. This method is designed to build muscle and strength with lighter weights, potentially benefiting older adults or those recovering from injury who cannot handle heavy loads. It requires professional instruction to ensure the pressure is safe and effective.

ModerateSupportsMEDIUM confidence
Applied basic and clinical research conducted over the past 10 years has demonstrated that KAATSU Training not only improves muscle mass and strength in healthy volunteers, but also benefits patients with cardiovascular and orthopedic conditions.
