FIGURE 1.
Effects of waterpipe smoke inhalation on serum cardiac troponin I (A) and cotinine levels (B) 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 = 7.*P < 0.05; ***P < 0.001 vs. CTL; #P < 0.05, ###P < 0.001 vs. S; &&&P < 0.001 vs. Ex.
