The effect of aerbioc exercises on the level of lipid and glucose in the blood of fasting men

Ramadan is the holy month for Muslims and they fast during this ‎month. The purpose of this study was evaluating influence of selected exercise program ‎and Ramadan fasting on plasma glucose, lipids and lipoproteins.‎ Methods and Subjects of this study were 32 healthy, young untrained men who ‎voluntarily participated in this study. They were divided randomly to two groups of ‎exercisers (n=17, age: 25.76±5.27) and controls (n=15, age: 25.42±3.99). Blood samples ‎were taken four times [1 day before the beginning of Ramadan Fasting (Pre-RF), 15th and ‎‎29th of the Ramadan and 30 days after the end of Ramadan Fasting(After- RF)]. Exercise ‎training included aerobic exercises (intensity: 70% of maximal heart rate, frequency: 3 ‎times a week, duration: 4 weeks). Statistical method of t and repeated measure tests were ‎used for analysis. Triglyceride (TG) and very low density lipoprotein (VLDL) were ‎significantly lower in exercise group at 15th of Ramadan and TG was significantly lower ‎After-Rf (P≤0.05). There was no significant difference between other variables including ‎low density lipoprotein (LDL), high density lipoprotein (HDL), total cholesterol (TC) and ‎fasting blood sugar (FBS) in exercise and control groups (p>0.05).In exercise group TG, ‎VLDL and FBS decreased in day 15 versus pre fasting, TG and VLDL increased in day ‎‎29 versus day 15 and decreased in After-RF versus day 15(P≤0.05).There were no ‎significant changes within measures of control group (p>0.05)‎ It seems that metabolic response to fasting is closely related to interactive ‎response of exercise and fasting.‎
