Comparing the Effect of Fasting and Physical Activity on Active and Non-active Male's Body Composition, Serum Osmolarity Levels and Some Parameters of Electrolytes

Ever since there is insufficient and incoherent information about the effect of the Ramadan Fasting together with regular exercise on levels of serum osmolarity، and electrolytes concentration. The aim of this study was to compare the effect of fasting and physical activity on active and non-active males’ body composition، serum osmolarity levels and some parameters of electrolytes. Twenty six healthy males، who were selected by convenience sampling method، were divided into two (active and non-active) groups. The Active group participated in football training for three sessions per week during the fasting month. All measurements were repeated on the first and last day of fasting month and were used to analyze the test results. The average differences were significantly decreased in weight، BMI، WHR، mineral، total water in two groups (P≤0. 05). There was a significant difference in average of BMI، WHR، body fat، mineral and total water between two groups (P≤0. 05). Within-group mean differences in glucose، potassium، urine and albumin in both groups were significant (P≤0. 05). Differences of serum osmolarity in between- and within-groups were not significant in both groups. While، glucose decreased significantly، the levels of the protein decreased، and urea increased significantly only in non active fasting group. According to these results، regular exercise together with the Ramadan fasting result in change in some serum osmolarity index، electrolytes and water. Therefore، it is necessary to protect the athletics against the malnutrition in Ramadan fasting by using the diet schedule and enough water.
