Investigation and Comparison of Short-Term and Long-Term Strength Training on Neutrophils, Lymphocytes and Monocytes Blood Factors in Untrained Male Students

The aim of the present study was to evaluate and compare the effects of short-term and long-term strength training increasingly on neutrophils, lymphocytes and monocytes blood factors in untrained male students Khatam University of Behbahan.

For this purpose, 45 male students between 18–22 years were selected. Subjects were categorized into three groups of 15 subjects randomly. These include a control Group 1, Group 2 with short-term strength training increasingly and Group 3 with long-term strength training increasingly. In order to examine data distribution between groups of Kolmogorov-Smirnov test for equality of variances assumption of intra-group study, Levene's test was used. To investigate the effectiveness of the practice of paired t-test was used. In a comparison test between the selected parameters in one-way analysis of variance was used for independent samples and to analyze and compare three groups of variables, Tukey test was used. The significance level for all tests was p ≥ 0.05 and statistical analysis was performed using SPSS statistical software.

The results showed that after a strength training, mean difference of the variable Neutrophil percentage in training groups and control group in post-test was significant p=0.016. Mean difference of the variable lymphocytes percentage in training groups and control group in post-test was not significant p=0.217. Mean difference of the variable monocytes percentage in training groups and control group in post-test was not significant p=0.114.

These results suggest that cell-mediated immunity in young boys is influenced by the intensity and duration of exercise.
