Dyslipidemia influences the effect of physical exercise on inflammatory markers on obese women in post-menopause: A randomized clinical trial.

Abstract

The hormonal modifications observed in post-menopausal are related to increased adiposity and alteration in the lipid profile besides physical and psychological changes. Physical exercises may attenuate these conditions and have been associated with low-grade inflammatory status, reducing the risk of cardiovascular diseases. This study aimed to evaluate the influence of dyslipidemia on the effect of physical exercise on inflammatory markers IL6, IL10, and TNF-α in obese post-menopausal women. A randomized clinical trial was carried out in seventy women divided into four groups: exercise without dyslipidemia (EG/n=11); exercise with dyslipidemia (EGD=24); control with dyslipidemia (CGD/n=22); and control without dyslipidemia (CG/n=13). The serum values of IL-6, IL-10, and TNF-α were measured before and after the intervention period, and the exercise program lasted 20weeks, in three weekly sessions of 75min each, with aerobic and strength exercises. The comparison of means was performed using the ANOVA test, repeated measures to analyze the interaction between the group and intervention time. There were a significant reduction in IL-6 values and an increase in IL-10/IL-6 and IL-10/TNF-α ratios only in the EG group. For serum TNF-α values, the EG and EGD groups showed significant reductions. The groups that practiced exercises did not present significant variation in the levels of IL-10. However, the CGD and GC groups showed a significant reduction in IL-10 after the intervention period.
