Redox Signaling Powers Up Aerobic Performance
April 11, 2011Posted by on
As the energy requirements of the cells and tissues increase during aerobic activity, oxygen and sugars in the blood must be able to be transferred from the lungs and energy stores into the muscle cells and tissues. Waste products like CO2 and excess lactates must be transferred out of the cells and tissues and back into the blood and out of the body. The efficiency at which the cells can move oxgen fuel and waste products back and forth through the blood and cellular membranes determines how long the body can sustain aerobic activity.
When the oxygen and energy demands of the muscle tissues exceed the ability of the body to maintain adequate delivery, the muscle cells and tissues start to burn internal energy stores anaerobically (without the use of oxygen), waste products (CO2 and lactates) start to build up and further interfere with the aerobic processes. When the internal energy stores of the muscle cells are exhausted, no more energy can be provided and muscle activity ceases completely.
Increasing the amount of balanced redox signaling molecules in the body helps normalize the redox potential in and around the cells and tissues. A balanced redox potential in the tissues increases the efficiency at which oxygen, fuels and wastes can be transferred in and out of cells and tissues, making the natural aerobic processes more efficient. If aerobic capacities are increased, then the natural length of time that aerobic activity can be sustained under high energy demands is also increased. The time that it takes to recover normal aerobic balance after an intense anaerobic effort is also shortened.
