	Control	Smoke	Exercise	Exercise + smoke
Initial body (g)	38.79 ± 3.33	38.56 ± 5.56	39.51 ± 6.39	39.53 ± 4.14
Final body (g)	33.59 ± 2.5	50.16 ± 3.0	33.34 ± 2.7	46.44 ± 4.3
Gain (%)	13.41	30.0	15.62	17.4
Diaphragm weight (mg)	98.8 ± 23.2	60.1 ± 13.	89.5 ± 39.4	109.9 ± 19.

Normal diaphragm muscle (control); exercise in the treadmill (exercise); group exercise in the treadmill associated to chronic cigarette smoke exposure (exercise + smoke); group submitted to chronic cigarette smoke exposure (smoke). Data are expressed as mean ± standard deviation. a = : compared to control group; b = : compared to smoke group; : intragroup comparison.
