Abstract

Background: The aim of this study is to investigate the effect of circadian rhythm on the maximal fat oxidation (MFO) and FATMAX in students without practice.
Materials and Methods: The subjects of this study were ten non-athletes male students (N=10), with the body mass index and maximal oxygen consumption below 50%, who were selected randomly. Run test was performed with three-minute stages and increased speed and slope to exhaustion at 6-8 am , 5-7 pm ,and 9.5-11 pm. Post hoc LSD test was used for describing the analytical findings and repeated measures to compare data in three times of morning, afternoon, and night.
Results: The results generally showed that average of maximal fat oxidation at night is more than evening and morning (.There is a slight difference between the afternoon and morning (p=0.006), but MFO and FATMAX mean in evening is more than morning and night. There is a slight difference between the morning and night (p=0.002)
Conclusion: So it can be concluded that circadian rhythm influences the maximal fat oxidation and fat oxidation is significantly higher in the evening than in the morning and it is good for fats.
