Protective Effect of Moderate-Intensity Continuous Training and High-Intensity Interval Training on Serum Levels of Oxidative Stress Parameters in Rats Treated with Cisplatin

Considering the antioxidant properties of physical activity, the aim of the present study was to investigate the effect of moderate-intensity continuous training (MICT) and high-intensity intermittent training (HIIT) on oxidative stress and total antioxidant capacity in rats treated with cisplatin.

In this experimental study, 24 male laboratory rats were randomly divided into four groups (control, control cisplatin, cisplatin + MICT, and cisplatin + HIIT). In cisplatin groups, 5.5mg/kg cisplatin was injected intraperitoneally. The training programs continued for 10 weeks. Twenty four hours after last training session, blood serum of rats was collected to examine the study variables. Data were analyzed using one-way analysis of variance.

In this study, cisplatin caused significant increase in malondialdehyde (MDA) (P=0.019), significant decrease in total antioxidant capacity (TAC) (P=0.014), and significant decrease in catalase (CAT) (P=0.001) in the control group compared to the cisplatin control group. MDA showed significant reduction in cisplatin+ MICT group (P=0.001) and cisplatin + HIIT group (P=0.001) compared to the cisplatin control group. Findings showed no significant difference in TAC between cisplatin + HIIT group and healthy controls (P=0.66). CAT in cisplatin + MICT group (P=0.12) and in cisplatin + HIIT group (P=0.177) was not found to be significantly different with that of the control group.

It seems that exercise at different intensities can be effective in reducing oxidative stress caused by cisplatin in rats.
