  • Introduction: Fasting in the month of Ramadan is a religious obligation and belief that is obligatory for all healthy and mature Muslims. The purpose of this study is to compare the effect of one month of fasting and regular exercise on biochemical and hematological indices of active and inactive men.
  • Methods: In this study, 40 healthy men between the ages of 15 and 35 were divided into two inactive fasting groups (20 people) and active fasting groups (20 people). Two blood samples were taken from both groups for biochemical and hematology tests on the first and 30th day of Ramadan. The data were analyzed using repeated analysis of variance test.
  • Results: In both groups, the average indices of hematocrit, number of red blood cells, TC, LDL, HDL, LDL/HDL, TC/HDL and VLDL at the end of Ramadan have decreased significantly compared to the beginning of Ramadan. HDL values increased significantly during fasting in active fasting group (P=0.023) and passive fasting group (P=0.042) at the beginning and end of the study. The decrease in FBS levels was significant only in the active fasting group (P<0.05).
  • Conclusion: Fasting in the holy month of Ramadan combined with regular sports activities can produce positive changes in serum hematological-biochemical indicators, which can be due to changes in the diet and biological reactions of the fasting people's body to hunger and physical activity during the month of Ramadan
