title: Effect of aerobic training and aerobic and resistance training on the inflammatory status of hypertensive older adults.
abstract: There is a relationship between high levels of inflammatory markers and low adhesion to the practice of physical activity in the older population. The objective of the present study was to compare the effect of two types of exercise programs, i.e., aerobic training and aerobic plus resistance training on the plasma levels of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) of elderly hypertensive subjects. Hypertensive older volunteers in use of antihypertensive drugs were randomized to three groups: aerobic group (AG), resistance and aerobic group (RAG) and control group (CG). Training lasted 10 weeks, with sessions held three times a week. Blood samples were collected before training and 24 h after completion of the 30 sessions for the determination of serum IL-6 and TNF-α levels. Body mass index was obtained before and after 10 weeks. After intervention, BMI values were lower in AG and RAG compared to CG (p < 0.001), IL-6 was reduced in AG compared to CG (p = 0.04), and TNF-α levels were lower only in RAG compared to CG (p = 0.01). Concluding, both types of training were effective in reducing BMI values in hypertensive older subjects. Aerobic exercise produced the reduction of plasma IL-6 levels. However, the combination of aerobic and resistance exercise, which would be more indicated for the prevention of loss of functionality with aging, showed lower TNF-α mediator after training than control group and a greater fall of TNF-α levels associated to higher BMI reduction.
