The Effects of a Session of Aerobic and Anaerobic Exercise on Leukocytes, And Hormonal Responses in Young Women

Background. Exercises with different intensities can cause changes in immune system factors and hormonal acute response. These changes may exceed the permissible limitations and weaken the system. Objectives. The purpose of this study was to compare the effect of an intensity aerobic and anaerobic training session on acute hormonal response and immune system factors. Methods. A total of 30 young female non-athlete students (age 20.7&plusmn;1 years old and BMI 23.2 &plusmn; 1.3) participated in the study voluntary. And randomly were divided into three groups: maximum aerobic, anaerobic test and control group (n = 10). from subjects before and after the test, blood samples were taken to measure cortisol , testosterone and leukocytes. For maximum aerobic test, Ellestad test was used, and for anaerobic, Cunningham and Faulkner treadmill test was used. Results. It is&nbsp;showed that the leukocytes in anaerobic test significantly increased (p<0.05). On the other hand, anaerobic exercise leads to a significant increase in testosterone level (p< 0.05) and a significant reduction of cortisol levels (p< 0.05). Conclusion. In general, these findings show that despite minor differences in the effects of physical activity on the hormonal responses and immune system, Increase of anabolic conditions after anaerobic activity may be increase of leukocytes.
