How It Works
The Adaptive Contrast switch creates simultaneous maximums of circulation and blood oxygen levels unachievable by any other known method:
- Blood flow to the target tissue is maximized by combined exertion and hypoxic challenge; then,
- A switch to an oxygen-rich respiratory mixture occurs;
- This results in a maximum dissolved plasma-oxygen level and simultaneously, maximum blood flow to the target tissue;
- Maximum tissue perfusion and maximum anti-inflammatory effect is thus achieved in the target tissue.
Hypoxic, or low oxygen exertion has been used and studied for many years. Low oxygen exertion compels the body to adapt to low oxygen conditions. The adaptive process creates very special conditions in the body:
- Blood flow increases to critical systems, controlled by the degree of adaptive challenge;
- Heart rate increases (even for non-athletes) to increase circulatory system flow;
- Dilates the vascular system to increase blood flow to distal tissue;
- Breath rate and volume increase to ensure oxygen extraction from air;
- Heart rate increases to pump more blood throughout body.
Research of extreme hypoxic exertion shows that the body dramatically blood flow to critical organ systems during low oxygen challenge. The transition to a preservation response shows that the circulatory system progressively shifts oxygen from the whole body to survival priority systems for energy production, the liver and kidneys, and for motor and cognitive function, the brain.
The preferential delivery of blood to critical organs during low-oxygen challenge occurs as the body progressively redirects blood carrying the increasingly limited oxygen supply to the most vital organs. The transition has two main processes:
- Up-regulation in circulation and respiration; as the respiratory rate increases, the heart beats faster and the vascular system dilates
- Progressive restriction of flow to secondary systems and dilation of blood flow to critical systems.
During an initial low oxygen challenge, the body goes through three general compensatory stages:
- Stage 1: Up-Regulation: Body-wide blood flow increases to compensate for reduced oxygen with increased respiration and circulation
- Stage 2: Reduction to Non-Critical Systems: Blood flow decreases to the digestive system and organs not critically necessary for fight or flight
- Stage 3: Preservation of blood flow to Critical Systems: Blood flow is maximized to critical systems, i.e., the brain, liver and kidneys.
In each stage, the adaptive challenge increases blood flow to specific organ systems:
- Stage 1 is the whole body;
- Stage 2 is critical systems less systems not-critical for fight or flight: digestion, spleen and pancreas;
- Stage 3 is only systems critical for survival in flight or flight: brain, liver and kidneys.
