title: The effect of ramadan fasting on biochemical and performance parameters in collegiate wrestlers.
abstract: OBJECTIVE
  This study was designed to evaluate the effect of Ramadan fasting on body composition, aerobic and anaerobic power, strength, plasma lipids profile and serum glucose among collegiate wrestlers.
  
  
  METHODS
  Fourteen male collegiate wrestlers (age, 20.12±2.5 yrs) volunteered as subjects for the study. Subjects were tested one week before the beginning of Ramadan, the last two days of Ramadan and the last two days of the 4th week after the end of Ramadan. The paired sample t-test was used to assess the differences in pre and post-performance tests and repeated measures ANOVA and Bonferroni post hoc test to determine differences between three blood samplings.
  
  
  RESULTS
  The results showed that except for anaerobic power and strength, body weight, body fat percentage and aerobic power at 4th week of Ramadan were significantly lower than pre-Ramadan values (P=0.05). Total cholesterol and low density lipoprotein levels decreased after Ramadan compared to pre-Ramadan (P= 0.011, P=0.001), however, a month after Ramadan, it reached to higher levels compared to pre-Ramadan period, which were not statistically significant. Similarly, significant decrease and increase were consequently observed in glucose and high density lipoprotein (P=0.001, P=0.045). Triacylglycerol and VLDL increased at the end of Ramadan compared to the period of time before Ramadan, and after Ramadan, it reached the lower levels compared to concentrations before Ramadan (P=0.133, P=0.133).
  
  
  CONCLUSIONS
  This study also indicated that Ramadan fasting appears to have significant effect on body composition, aerobic power and lipid profile.
