Exercise-induced changes in diaphragmatic bioenergetic and antioxidant capacity

Exerc Sport Sci Rev. 2002 Apr;30(2):69-74. doi: 10.1097/00003677-200204000-00005.

Abstract

The primary inspiratory muscle in mammals is the diaphragm. Endurance exercise elevates both the oxidative and antioxidant capacity of the costal and crural diaphragm. These exercise-induced changes in oxidative and antioxidant capacity occur rapidly after the onset of training and are associated with reduced oxidative injury and improved diaphragmatic endurance.
