Exercise Prevents Diaphragm Wasting Induced by Cigarette Smoke through Modulation of Antioxidant Genes and Metalloproteinases

Figure 1

Results of the tests performed on the treadmill to evaluate the intensity of aerobic conditioning of the studied mice. Tests were performed before the beginning of the exposure to cigarette smoke (time 0) and 24 weeks of the protocol. (a) Time that the mice could exercise in the treadmill; (b) maximal speed reached by each mouse among the four experimental groups. Data are presented as means and standard deviation. A = : compared to control group. B = : compared to smoke group.
