The science of CVAC

We believe that improved physical conditioning supports all of the body's natural energy systems. CVAC Systems, Inc. is interested in supporting the exploration of the varied expressions of the body's response to the whole body adaptive conditioning provided by the CVAC Process.

01 · Compression
Air returnsFiltered air is returned to the Pod. Density rises and the body reads a higher barometric load.
02 · Decompression
Air is drawn outPressure falls. The air thins and the challenge arrives without a single joint being loaded.
03 · Adaptation
The body respondsTension and resolution repeat on a patterned rhythm across one 20 minute session.

Independent investigators have measured the CVAC Process against arterial oxygen saturation, glucose metabolism and pain. The record below is reproduced in full.

  1. Key takeaway

    A validation study performed at the University of Hawaii showed that it is potentially the challenge created through the delivery of the patterned low-barometric pressures of the CVAC Process that allows the body to become more efficient at utilizing available oxygen; thus improving the oxygen-carrying capacity of the blood.

  2. Key takeaway

    A blinded, placebo-controlled study showed the CVAC Process mirrored the effects of high-intensity exercise on glycolytic energy production in non-diabetic middle-aged men. The men in the study participated in less than three hours of exercise per week.

  3. Key takeaway

    Some people who are overweight have difficulty with traditional forms of exercise. In this study, people who were overweight used the CVAC System for 40 minutes a day for 5 days under the supervision of Karen Herbst PhD, MD. Dr. Herbst reported a statistically significant reduction in weight in those individuals in her study.
