Effect of intestinal parasites on anaerobic performance and muscle strength in athletes

Athletes have the risk of transmitting intestinal parasites in sports environments, leading to their poor performance. This study aimed to investigate iron deficiency, iron deficiency anemia, anaerobic performance, and muscle strength in athletes with intestinal parasites. It was conducted by the Ministry of Youth and Sports, General Directorate of Sports Services, Department of Health Affairs in 2018. The stool test results of the athletes were examined. The iron deficiency, iron deficiency anemia, anaerobic performance, and muscle strength were determined by stool sample analysis (study group) and compared with those of 28 athletes who performed the same sports and had no parasites (control group). The iron deficiency and iron deficiency anemia in all athletes were evaluated using iron and ferritin levels in blood analysis. The anaerobic performance was assessed using the Wingate test. The isokinetic muscle strength was evaluated using the IsoMed 2000 isokinetic dynamometer. No statistically significant difference in blood analysis and iron and ferritin levels was found between the groups. No athlete had iron deficiency or iron deficiency anemia. On comparing the anaerobic performances of the groups, no statistically significant difference in WanT parameters was observed. A statistically significant difference was found in the strength of the dominant leg knee extensor muscles at an angular velocity of 60º/s, but no statistically significant differences were noted in other muscle strength parameters. Asymptomatic intestinal parasites did not lead to iron deficiency or iron deficiency anemia and did not affect anaerobic performance in athletes, but adversely affected the strength of dominant leg knee extensor muscles.
