ABSTRACT
Background and purpose: Every type of exercises could lead to different immune responses in human body. The purpose of this study was to compare the acute effects of endurance exercises [EE], resistance exercises [RE] and concurrent exercises [CE] on serum interleukin-17 [IL-17] concentrations and number of lymphocytes, monocytes, and neutrophils in active men.
Materials and Methods: Twenty healthy young and active men [Age: 21.69 +/- 2.66; BMI: 21.92 +/- 1.89; Fat%: 14.49 +/- 3.05] voluntarily participated in this study and randomly were assigned into three groups: EE [n=7], RE [n=6] and CE [n=7]. Subjects performed special exercise protocol for each group consisted of 45 minute. IL-17 serum concentrations were measured by ELISA method and so numbers of some classes of leukocytes were computed [Pre, immediate and 1 hour post-exercises]. Data were analyzed using Repeated-Measures analysis of variance, One-Way ANOVA and Tukey post-hoc and Paird T-test at the significance level of a=0.05
Results: Changes in the serum levels of interleukin-17 was significantly different between groups immediately after exercise and 1 h post-exercise. Also, lymphocytes and neutrophils numbers 1 h post-exercise and monocytes and neutrophils numbers, 1 h post-exercise compared to basal levels were significantly different between three exercise groups, respectively [p<0.05].
Conclusion:Type of exercise has an effective role in IL-17, neutrophils, lymphocytes, and monocytes responses. Based on changes pattern of serum IL-17 in groups, it seems that CE can modify the effects of RE and EE.
