Effects of Spinning Workout and Green Tea Consumption on the Anti-inflammatory and Inflammatory Markers and Body Composition of Overweight Women

Background: Systematic inflammations are associated with cardiovascular diseases. The production of inflammatory mediators increases in a sedentary lifestyle and reduces with regular exercise. Objectives: The present study aimed to evaluate the effects of eight weeks of spinning workout and green tea supplementation on the anti-inflammatory and inflammatory markers and body composition of overweight women. Methods: This study was conducted on 32 overweight women who voluntarily participated in the research and were randomly assigned to the groups of spinning-green tea (SP-GT; n = 11), spinning-placebo (SP-PL; n = 11), and control (no exercise/placebo; n = 10). The experimental groups carried out eight weeks of spinning workout three days a week non-consecutively with the intensity of 11 - 17 rating of perceived exertion (RPE). Serum concentrations of tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), and interleukin- 10 (IL-10) were measured before the intervention and 48 hours after the last training session. In addition, body mass index (BMI) and body fat percentage (BF%) were measured. Results: After eight weeks of the intervention, BMI, BF%, and TNF-α significantly reduced in the SP-GT and SP-PL groups (P ≤ 0.05). Although the change in IL-6 was not significant in the intervention groups (P > 0.05), it significantly increased in the control group (P = 0.011). Moreover, a significant increase was observed in IL-10 in the SP-GT and SP-PL groups (P = 0.001). Conclusions: According to the results, spinning workout improved the inflammatorymarkers and body composition independent of supplementation, while green tea had a greater effect on IL-10. Therefore, spinning workout could be used for the prevention of cardiovascular risk factors through the improvement of systematic inflammation.
