Materials & Methods: In this experimental study Twenty-four rats (4-week old, 72±8 gr) were divided accidentally to control and training groups. The samples after 6 weeks anaerobic exercise training, were exposed to Environment hypoxia and lived three weeks over there. Another group Concurrent with exposure to hypoxic environment, implementation Taper (30% reduction in exercise intensity) technique. In lung tissue, the expression of Bax and Bcl2 was studied by the immunohistochemical methods. One-way Anova was performed to analyze data. P≤0.05 was considered statistically significant. Results:Expression of Bcl2 protein in trained rats and exposed to hypoxic stress was increased And reduced after a 3-week use of the taper(P>0.05). Expression of Bax protein in trained rats and exposed to hypoxic stress was increased (P≤0.05), and reduced after a 3-week use of the taper (P>0.05). Conclusion: It seems that, Medium hypoxia is able to apply Apoptotic effects in lung of rats that underwent intensive exercise and likely the use of intensity taper reduces these effects.
