Surfactant... the lungs produce a solution (surfactant) to reduce the surface tension properties of alveoli. Surfactant functions also include easier alveoli expansion, more stable alveoli size and shape inproving surface area for gas exchange, improved lung volume and compliance, reduced respiratory muscle work, as well as the removal of excess water and neutralization of chemcial pollutants and toxins

Production of surfactant in the lungs increases under certain conditions. The reduction of surface tension that improves gas exchange in the lungs can be controlled to some degree by exercise that employs specific breathing speeds, depth, etc. Surfactant synthesis can also be enhanced by the stimulation of various hormones.

The unique breathing and movement combinations integrated into Body'Fit pH Fitness design improve lung health and respiratory efficiency by increasing the production of surfactant beyond what normally occurs during hyperventilation. Each of the 24 exercises comes with it's optimal breathing pattern carefully chosen to maximize surfactant and reduce surface tension. Furthermore, surfactant synthesis is stimulated by the calculated release of glucocorticoids, thyroid hormone, epinephrine and prostaglandins during performance of the Body'Fit pH Fitness exercise routine.
