Introduction: High Intensity exercise is one of the effective factors on immune and inflammatory factors. The purpose of this study was to determine the single session of high intensity interval exercise (CrossFit) on levels of leukocytes, neutrophils, lymphocytes, monocytes, lactic acid and C- reactive protein (CRP) of male athletes to make decision for doing this exercise in coronavirus prevalence period. Methods: In this Causal-comparative study, 32 male athletes were selected as participants (with mean of age 26.9±4.7 year, height 177 ± 5 cm, weight 80.7±6.4 kg). Exercise session included a 400-meter running on treadmill,triple dead lift movement, pull-up (30 repetition), swing of kettlebell (30 kg) and throwing of 20 sand balls. Blood sampling, CBC and biochemistry auto analyzer tests were used for measuring leukocytes, lactic acid and CRP. In addition, ANOVA with repeated measure, Friedman, Wil-kaksun and Bonferroni post hoc tests were used to examine the differences between variables in resting position, post-exercise, and after modify the results by consideration of plasma volume changes using SPSS version 16 software. Results: The results showed significant increase in lactic acid (P0.05). Conclusion: The single session of high intensity interval exercise makes disorder in immune and inflammation responses in athletes. Therefore, it has been suggested not to do intensive exercise at coronavirus prevalence period and consider enough time for recovery after high intensity exercise.
