Comparison of the effects of endurance, resistance, and concurrent exercises on serum interleukin-17 concentrations in active men

Background and 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. 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 α=0.05. 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). 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.
