The purpose of the study: The objective of this research was to evaluate the effect of doing aerobic exercise along with vitamin C supplementation on Homocysteine and insulin levels of obese boys. Methodology: The method of current research was quasi-experimental. In this research, the researcher evaluated the relationship between variables which have not been manipulated by the researcher rather have occurred in the past which means that although they have happened in the past, they were under investigation in the current study. Quasi-experimental research is a systematic experimental study in which the researcher does not have direct control over the independent variables, since they have already occurred and have been studied. In this research, 40 obese boys aged 10 to 15 years old with a percentile of body mass index of 95% were selected and randomly assigned into control, exercise and vitamin C groups. The exercise group included performing the exercises at 50-70% of maximal heart rate for 3 sessions per week during 8 weeks. Data of the study were analyzed using ANOVA and t test. Results: The results showed that aerobic exercise along with vitamin C supplementation significantly decreased glucose, insulin and Homocysteine in obese boys (p <0.05). Conclusion: Aerobic exercise and taking vitamin C might lead to negative adjustment of Homocysteine and insulin resistance in obese boys. Moreover, the combination of aerobic exercise and vitamin C supplementation is associated with the improvement of these effects.
