Objective: The use of non-enzymatic antioxidants in the form of dietary supplements has a positive effect on reducing oxidative stress, and preventing apoptosis as they interrupt free radicals. The aim of this study was to investigate the aerobic exercise and L-carnitine consumption impacts on diabetes induced apoptosis, oxidative stress factors, and mitochondrial enzymes in rats. Materials and Methods: In this Clinical trial study, ۴۵ male Wistar rats (۲۰۰-۳۰۰ g) were divided into six groups including sham, healthy control, diabetic control, diabetic & L-carnitine, diabetic & aerobic exercise, diabetic receiving L-carnitine & aerobic exercise . The rats attained a diabetic state with a single dose of STZ intraperitoneal injection (۵۵ mg/kg body weight) and receiving L-carnitine ۱۰۰ mg per day. The aerobic exercise protocol including five sessions per week was administered. The heart tissues of the dependent variables were measured by ELISA ۲۴ hours after the last session of the exercise program. One-way ANOVA and Tukey's post hoc test at P-value< ۰.۰۵ were used to analyze the data. Results: result show that aerobic exercise and L-carnitine consumption have a significant effect on BAX (P-value= ۰.۰۰۱), Bcl-۲ (P-value= ۰.۰۰۱), and SOD (P-value= ۰.۰۰۱) in diabetic rats. Conclusion: The results of the present study confirm the role of aerobic exercise and L-carnitine in improving the indices of apoptosis and oxidative stress in type ۲ diabetic rats
