Abstract: 
Research concerning the effects of exercise of human immune system has revealed contradictory results. It has been shown that, in general, moderate and regular exercise increases some aspects of immune systems functions in contrast to intensive exercise, which can result in inflammatory responses of the immunological system and acute or chronic inflammation of muscular system in athletes. The aim of this study was to evaluate the effects of eccentric & concentric exercises on T-Iymphocyte sub-populations and IL-6 concentration in female athletes.
12 female athletes (mean age 21 ± 0.75 years old, weight 57 ± 5.34 kg, and height 162 ± 2.71 cm, respectively) were selected to participate in this study.
Subjects performed 13 minutes of eccentric exercise with pacing on treadmill according to Ellestad protocol and 13 minutes concentric exercise with pacing on treadmill in opposite direction. Blood samples were collected before, immediately after, one and two hours after exercise. Absolute numbers of T lymphocyte sub - populations including CD4+, CD8+, CD3+, CD56+ (NKC) and the ratio of CD4+/ CD8+ were determined in blood samples using flowcytometrey and IL-6 concentration was determined using ELISA. The results showed that absolute numbers of CD4+, CD3+, CD8+, CD56+ (NKC) increased significantly immediately after exercise and decreased significantly after one hour compared to the resting status levels.IL-6 concentrations showed significant increase after eccentric exercise.
The results indicated that short term but heavy exercise can temporary suppress the immune system. This effect will increase individual susceptibility to pathogens in long term.
