Aim: The present study investigates the effects of one month of fasting Ramadan on some blood variables including fasting blood glucose, TC, TG, HDL, LDL, VLDL, urea, creatinine, SGOT, SGPT, ALP, hs-CRP, body weight, fat weight, and lean body mass.
Method: 14 healthy male soccer players (who continued their regular exercise program through Ramadan) participated in this study. The subjects were randomly divided into fasting (age: 22.61±3.83 years, height: 174.12±6.33 cm, weight: 69.6±15.052 kg) and control groups (age: 24.7±3.54 years, height: 172.98±5.44 cm, weight: 67.74±10.15 kg). Blood samples were taken on two occasions; the first at 10 am, one day before Ramadan and the second at 5 pm of the 29th (both following 12 hours of fasting). The data was analyzed by a paried t-test (at 0.05 statistical significance level) after the normal data distribution order was verified using the k-s test.
Results: One month of fasting had no significant on any of the variables, in any group.
Conclusion: It can be concluded that fasting probably because of the previous adaptations, could have no hazardous consequences on athlete health if there is no detectable fluctuations in daily caloric intake and physical activity level.
