Abstract
One of the controversial topics that have attracted the attention of experts is the effects of different methods and intensities of exercise on the immune system. Interferon gamma-induced protein 10 (IP-10) is a small cytokine involved in the chemical uptake of certain immune system factors such as monocytes/ macrophages and T cells. The aim of this study was to investigate the effect of different intensities of interval training on IP-10 gene expression in adult male rats.
In this study, twenty-four rats were divided into three groups: (1) High-intensity Training, (2) Low-intensity Training, and (3) Control groups. Training groups trained for 8 weeks and 5 days a week. The HIT group exercise program consists of running on a treadmill with five alternatives (8 minutes with 85-90% VO2max intensity and 2 minutes 50-60% VO2max intensity) and the LIT group exercise program is included five alternatives (8 minutes with 55-60% VO2max intensity and 2 minutes 45-50% VO2max intensity), that did a specific hour of the day and at the same time, the control group had no exercise. The expression of the IP-10 gene was measured in the soleus muscle. The data were analyzed by one-way ANOVA and Tukey post hoc test and statistical differences were considered significant at P<0.05.
The results of this study showed that the expression levels of the IP-10 gene in the HIT group were significantly higher than the control group (P = 0.01, P = 0.04), while the levels of the IP-10 gene in the LIT groups were not significantly different than the control group (P = 0.2, P = 0.1). According to the results of the present study, it seems that High-intensity exercise can be more effective than low intensity in increasing immunity, which is dependent on IP-10 levels.
