Effects of waterpipe smoke inhalation on Bax levels in serum (A) and in the heart (B), and Bcl-2 levels in serum (C) and in the heart (D) in experimental groups. CTL, control group; Ex, group subjected to exercise training for 8 weeks; S, group subjected to waterpipe tobacco smoke inhalation for 8 weeks; Ex + S, group subjected to exercise training and waterpipe tobacco smoke inhalation for 8 weeks. The results are presented as mean ± SEM, n = (6–7). *P < 0.05, ***P < 0.001 vs. CTL; #P < 0.05, ###P < 0.001 vs. S; &&P < 0.01, &&&P < 0.001 vs. Ex.
