Background and Objectives: Type, intensity and duration of exercises exert pivotal effects on athletes’ immune system and probably athletes’ susceptibility to upper respiratory tract infections. In this study we examined the effects of one session of moderate-intensity exercise on male judoists’ circulating blood neutrophil counts (BNC) and respiratory burst, and self-reported upper respiratory clinical infections 24 hours after the exercise and during the sport seasons. Methods: Ten male judoists after obtaining informed consent were included in the study. The athletes took part in a session of moderate-intensity exercise (60 minutes running on a treadmill) at 60% of maximum heart rate. Blood samples were drawn at rest immediately after the exercise. Blood neutrophil count and percentage of Phorbol Myristate Acetate (PMA) stimulated neutrophils in whole blood were assessed [as a marker of oxidative burst (OB) quality]. Athletes were asked about any signs of upper respiratory infections 24 hours after the exercise and during sport seasons. Paired-t test was used for statistical analysis and statistical significance was set at p
