- Abstract
Introduction: Hunger and reduction in regular energy intake can lead to a number of problems based on their intensity. For instance, low energy level can cause blood cell production to decline or it may pose a higher risk of anemia. It can also weaken the immune system and platelet aggregation or negatively affect clot formation. This study aimed to have a closer look at fasting and regular physical activity and their impacts on body composition and blood hematological-biochemical parameters among professional wrestlers. Method: In this semi-experimental study, 9 subjects were selected by convenience sampling. The selected training program included participation in this exerciseprogram, 90 min per session, 6 times per week for a period of one month. Blood samples were obtained four times: before the start of Ramadan, 2 weeks after the start, during the last week and 2 weeks after the end of Ramadan. To make intra-group comparison, repeated measure analysis of variance was used. For all statistical comparisons, the level of significance was considered at P<0.05. Results: Body weight and red blood cell count (RBC) dropped significantly at the end of Ramadan (Respectively P= 0.001 and P=0.034). However, the number of white blood cells (WBC) and circulating platelets (PLT) significantly increased during fasting (Respectively P= 0.048 and P=0.042). As a matter of fact, PLT and WBC were the only factors which dramatically increased during fasting. Intra-group variations of tetracycline (TC), lowdensity lipoprotein (LDL), LDL: high-density lipoprotein (HDL), triglyceride (TG): HDL and TC: HDL reduced at the end of Ramadan. However, HDL levels drastically increased during fasting (P=0.05). Conclusion: Based on the results of the research, despite being a regular activity and fasting has beneficial effects on lipid profile in athletes, however, they can with tangible changes in hematological factors may lead to weaken the immune system of athletes.
