KAATSU blood flow restriction (BFR) modalities are the original and most profound biohack for health, rehabilitation and recovery. Invented in 1966 by Dr. Yoshiaki Sato in Tokyo, Japan, and protected by 47 patents, KAATSU equipment and unique protocols have an impressive and unprecedented safety track record with over 20 million individual KAATSU sessions performed in 48 countries across the globe. Back by 50+ years of expertise, we are excited to introduce the next generation of BFR equipment, the KAATSU Cycle 2.0.

Weighing in at just 3.5 ounces, the KAATSU Cycle 2.0 is the most versatile and lightest pneumatic BFR system on the market. In combination with precise algorithm-controlled limb pressure, KAATSU’s narrow, flexible bands yield to muscle contractions, providing safe and effective training. Unlike other BFR devices, KAATSU gives the freedom to train and rehabilitate 100% untethered. As a result, users have a full range of motion proving complete control and opportunity for a wide variety of sport-specific exercises.

From elite athletes to baby boomers, and everyone in between, KAATSU is the golden standard for BFR training.


The Science Behind KAATSU

Blood Flow Moderation

KAATSU safely reduces venous flow, leading blood to pool in your limbs longer than normal.

During KAATSU capillaries lengthen and expand to help improve circulation and vascular elasticity.


Nitric Oxide Production

KAATSU leads to production of VEGF (vascular endothelial growth factor) and nitric oxide in the body.

Nitric oxide allows blood vessels to constrict and relax, and also regulates the inflammatory cells in the blood vessel walls.

Lactic acid builds up in the muscle causing the pituitary gland to secrete growth hormone

Growth hormone is secreted in large amounts activating the body’s metabolism.


KAATSU Band Design

KAATSU is generically described by Japanese physicians as Blood Flow Modification. KAATSU is not Blood Flow Restriction (BFR) due to a variety of factors including the specific design and engineering of the KAATSU Air Bands.

The stretchable Bands are designed to reduce venous flow (blood flow back to the torso). The Bands do not occlude arterial flow (blood flow to the limbs). This is very different from blood pressure cuffs that are specifically designed to occlude (cut off) blood flow to the limbs.

The width of the Bands is also much different than a blood pressure cuff (i.e., it avoids arterial flow occlusion). The Bands very importantly allows for ease of movement of the limbs (for walking, running, cycling, calisthenics, physical therapy, swimming, throwing, pulling, pushing or any specific movements required in sports or fitness).

The Bands include baffles and a stretchable air bladder that inflates uniformly and towards the limb, precisely controlled by the KAATSU monitoring units (e.g., KAATSU Master 2.0, KAATSU Nano, KAATSU Wearables).

The Bands can be immediately deflated by either pushing buttons on the monitoring units, depressing the value on the connectors, or releasing the Velcro on the Bands.
