Skeletal Muscle Circulation... neural and local factors regulate circulation of blood flow to the muscles that move the skeleton during exercise.

Usually neural and local regulating mechanisms oppose each other and during muscle contraction the local vasodilators (metabolites) supervene. Body'Fit pH Fitness™ is designed to mitigate local vasodilators and enhance the neural mechanisms in order to get More Out of Exercise™. It's the build up of metabolites (lactic acid, etc) which typically occurs during exercise that dilates resistance vessels in skeletal muscle circulation - until tissue edema results with the 30-fold or greater blood flow, and metabolic rate in muscle tissue rises 100-fold. Of course this is at the expense of deep tissue like viscera.

Some sympathetic-mediated vasoconstriction occurs in active muscle and increases in strenuous exercise when more than half of the total body musculature is contracting.  For example, in experiments in which one leg is working at maximal levels and the other leg starts to work, blood flow decreases to the first working leg due to neural release of norepinephrine.  However most of the norepinephrine that increases significantly in most exercise comes from sympathetic nerves in the active muscles.  Whereas in Body'Fit pH Fitness, release of norepinephrine is enhanced primarily by stimulating the spine and neural plexes at the lumbar level right from the start.

Although Body'Fit pH optimizes the neural release of norepinephrine, it does so at the same time the exercise routine stimulates the release of adenosine. Adenosine converts the action of adrenaline from vasoconstriction to vasodilation; and dilation of muscle resistance vessels can then be engineered to become primarily driven by neural mechanisms. Understandably the importance of this is it gives more control of total body cardo vascular circulation over to exercise design. As stated this is in contrast to the vaso constriction that exercise typically illicits reactively to the stimulation of sympathetic nerve endings causing the release of norepinephrine in skeletal muscle, as well as epinephrine if in sufficiently large doses. With more neural control, the adaptation of skeletal muscle to imposed demands during exercise can then be faster, and also possible (if necessary) at a much lower muscle metabolic rate (if accomplished under optimal conditions without lactic acid build-up). One of the ways this is achieved with Body'Fit pH Fitness design is to oxygenate each muscle group at the sequential moment when it isn't competing for oxygen with other muscles and tissues of greater blood volume.

Furthermore stimulation of the carotid sinus, which dilates skeletal muscle vessels, is kept to a minimum by waiting till later in the exercise series when cardio vascular circulation is optimized to work the neck muscles. The rise in temperature which dilates muscle blood vessels as well, is also prevented from going to the point of overheating by the unique Body'Fit pH Fitness movement/ breathing combinations. Another example of how Body'Fit design equilibriates circulation between muscles and internal organs is the incorporation of innate basal tone of blood vessels. Innate basal tone is the natural elastic tension that keeps blood vessels from overstretching.  In Body'Fit pH Fitness it helps keep disportionate circulation in congruence with the goal of equilibriating circulation as vessel constriction and dilation responds to neural mechanisms accordingly. Thereby circulation to organs is increased rather than decreased during exercise... and overall health and vitality which depends more on the function of our organs than the size of our muscles, is improved. Needless to say if the intricate design of Body'Fit pH Fitness did not precisely fit the physiologic needs of the total body for each movement during performance of the exercise routine, this purpose would not be accomplished at all degrees of exercise speed, duration, and intensity.
