Aims: Restriction of fluid intake during Ramadan is one of the most common causes of renal dysfunction. The aim of this study was to compare the effect of one month fasting along with regular exercise on male wrestlers’ electrolytes changes and serum osmolality. Materials & Methods: This semi-experimental study with repeated tests design was done on male wrestlers in Ramadan June and August 2014 (about 16-hour fasting). Among volunteers 9 elite and healthy wrestlers with 8 years experiences were selected using selective available and purposive sampling. Serum electrolytes and body compounds were measured 3 days before the Ramadan, 14 days after fasting and two weeks after Ramadan in the equal conditions. Data were analyzed using analysis of variance of repeated measures test. Findings: Body weight (p=0.001) and the body water amount (p=0.037) were reduced at the end of Ramadan significantly. Urea within group mean changes (p=0.049), Creatinine (p=0.031), Uric Acid (p=0.0001) and Sodium (p=0.01) during Ramadan were increased significantly compared with the beginning of Ramadan. Serum osmolality within group changes mean (p=0.001) increased during Ramadan significantly. Conclusion: Fasting increases serum electrolytes and osmolality in professional athletes.
