V02max is the maximum amount of oxygen in millilitres muscles can use in one minute per kilogram of body weight. Prior to the emergence of Body'Fit pH Fitness™ system of exercise (short form... pHx™), numerous studies have shown that VO2max can be increased by working large muscles at an intensity that raises heart rate enough - to a level that achieves V02max in working muscles for at least 20 minutes three to five times a week. Of course it wasn't previously possible for small muscles, such as those in the wrist, to reach VO2max even at maximum heart rate.

The physical limitations that restrict the rate at which energy can be released aerobically are dependent upon:

• the chemical ability of the muscular cellular tissue system to use oxygen in breaking down fuels
• the combined ability of cardiovascular and pulmonary systems to transport the oxygen to the muscular tissue system

A study by Saltin B, Rowell LB. concluded that it is the delivery of oxygen to active tissues that is the major limiting factor to VO2max. A study by Gollnick PD et al. showed a weak relationship between the body's ability to utilize the available oxygen and VO2max.

Understandably fatigue is a factor that must be carefully monitored to prevent overtraining. Therefore endurance training at a percentage of V02max is the route most coaches and athletes have chosen in the past.

It's possible to radically improve on the rate at which energy can be released aerobically with:

•    rapid normalization of body pH (in minutes instead of hours or even days) combined with oxygenation of muscles in order of greatest blood volume, optimizes the chemical ability of muscular cellular tissue system to use oxygen in breaking down fuels
•    the building of oxygen reserves in deep organs with specialized engineering of cardio vascular circulation in order of greatest blood volume combined with a ventilation/ perfusion (V/Q ratio) closer to a value of one (for greater respiratory efficiency). 

With the proper sequencing of movements, oxygen transport to both organ and muscle tissue is optimized for greater absorption in all the cells, rendering competition for oxygen unnecessary.
