Base SKU
The compression of the non-inflated KAATSU Air Bands and KAATSU Aqua Bands when the Air Bands are first manually affixed to the limbs.  Also known as Base Pressure and measured in SKU (Standard KAATSU Units).

BFM or Blood Flow Moderation
BFM is the generic term for KAATSU Training.

BFR or Blood Flow Restriction
Also known as occlusion training or tourniquet training.  Blood flow restriction in the limbs is caused by the tightening of knee wraps, ropes, tubing, or blood pressure cuffs around the limbs. BFR is not KAATSU Training.

Biceps Curls
Any type of weight training or resistance exercises or KAATSU Training that target the biceps branchii muscle where the hands are raised towards the shoulders until the forearms are vertical with the elbows and upper arm remaining close to the body.

Capillary Refill Time or CRT
The time in seconds taken for color to return to an external capillary bed (e.g., in the palm of the hands or above the knee on the quadriceps) after pressure is applied by a thumb on the skin to purposefully cause temporary blanching.

Central Nervous System
The complex of nerve tissues in the brain and spinal cord that controls the activities of the body.

CNS

Cycle 20
An 8-step process of releasing and applying pressure on either the upper arms or upper legs. One cycle includes the application of pressure for 20 seconds and the subsequent release of pressure for 5 seconds. There are 8 cycles in the Cycle 20 process that takes 3 minutes 20 seconds in duration with a Base SKU of 15 and an Optimal SKU of 100. This function is in the KAATSU Master, KAATSU Master 2.0, KAATSU Wearables, KAATSU Nano and KAATSU Cycle equipment.

One cycle includes the application of pressure for 40 seconds and the subsequent release of pressure for 10 seconds. There are 8 cycles in the Cycle 40 process that takes 6 minutes 40 seconds in duration with a Base SKU of 20 and an Optimal SKU of 150. This function is in the KAATSU Cycle equipment.

Cycle 60
An 8-step process of releasing and applying pressure on either the upper arms or upper legs. One cycle includes the application of pressure for 60 seconds and the subsequent release of pressure for 20 seconds. There are 8 cycles in the Cycle 60 process that takes 10 minutes 40 seconds in duration with a Base SKU of 25 and an Optimal SKU of 200. This function is in the KAATSU Cycle equipment.
