The effect of one week of progressive and exhaustive exercise in day on immune parameters in active girls

The type of training and quality of performance affect health and athletic success. The purpose of this research was to study the continuous effect of one week of progressive and exhaustive exercise in day on immune parameters in active girls. 13 healthy girl student of physical education with age 20.33±1.73 years, weight 56.80±6.17 kg, height 161.83±5.10 cm, aerobic capacity 40.88±5.06 ml/kg/min participated in this study voluntarily, were selected and randomly divided in 2 groups: experimental group (single session of exercise in a day, n=7) and control group(n=6). Blood samples were taken 5 times: 1) 24 h before exercise for detecting baseline ofleucocytes, lymphocytes and neutrophiles (pre- test condition); 3 times after exercise in the first, third and seventh, and last day of the exercise and 24 h after last exercise. (Post-test condition) Statistical operations: ANOVA test, LSD post hoc test and paired t-test were used to analyze data at significance p≤0.05. The findings of this study indicated that the count of leucocytes, lymphocytes and neutrophiles increased significantly in 3 post tests relative to baseline and in comparison with control group (p≤0.05). 2) However, the training brought significant increases in count of parameters but they were returned to baseline after 24 h rest. 3) The count of leucocytes and neutrophiles was changed similarly and the neutrophiles count increased more than other parameters. 4) Repeated training caused reduction in number of leucocytes, lymphocytes and neutrophiles from first day to seven day in experimental group. In general, the result of this study demonstrated that single session of exercise training for one week increased significantly the number of leucocytes, lymphocytes and neutrophiles in active girls but, the count of parameters returned to the baseline after 24h rest, presumably, there were no negative effect on immune system in active girls.
