      Background and Aim Apoptosis or programmed death is active biological process and reversible that the balance between growth and cell death in various tissues, particularly myocardial tissue is essential role. The aim of this study was the effect of 8 weeks High Intensity Interval Training (HIIT) with and without food restriction on gene expression of Caspase 3 and 9 in rats. Methods & Materials This study was experimental multi group design with control group which conducted on 30 rats with two months old male. Subjects were divided in to five homogenous groups including base control, control, caloric restriction, interval exercise training and caloric restriction+interval exercise training. Training groups five sessions in weeks were participated in interval exercise training for 8 weeks. The level of gene expression of the proteins Caspase 3 and 9 was evaluated by Real Time-PCR. Dates were analyzed using the 1-way ANOVA at the level of (P<0.05). Ethical Considerations The protocol of this study was approved by the Medical Committee of Sanandaj University of Medical Sciences (Code: IR.MYK.REC.1397.5022). Results The results showed that the training group had a significant decrease in gene expression of Caspase 3 in comparison with caloric restriction+exercise training (P<0.05). Also, exercise training and exercise training+caloric restriction significantly decrease in the gene expression of Caspase 9 compared to caloric restriction, base control and control (P<0.05) and significantly decrease in the gene expression of Caspase 3 compared to base control and control (P<0.05). Conclusion According to the results, it seems that high intensity interval training with and without calorie restriction provides the necessary adaptations to inhibit or stop apoptosis induced by aerobic exercise.
