Phosphate homeotasis in healthy subjects during prolonged periodic and continuous hypokinesia

Higher Pi imbalance with higher than lower physical activity shows that the risk of higher Pi imbalance is inversely related to the intensity of physical activity. Lower Pi absorption with higher than lower Pi imbalance shows that the risk of lower Pi absorption is inversely related to magnitude of Pi imbalance. In conclusion Pi imbalance increases more with higher than lower physical activity and that Pi absorption decreases more with higher than lower Pi imbalance indicating that during HK the use of Pi decreases more with higher than lower physical activity.
