Single 30min treadmill exercise session suppresses the production of pro-inflammatory cytokines and oxidative stress in obese female adolescents.

Abstract

Regular treadmill exercise may result in changes in pro-inflammatory cytokines and oxidative stress. However, the way acute treadmill exercise mechanisms affect the changes in pro-inflammatory cytokines and oxidative stress in obese has not been comprehensively exposed. This study aimed to analyze the pro-inflammatory cytokines and oxidative stress between 30min before treadmill exercise and 24h after treadmill exercise in obese adolescents. A total of 20 obese females aged 19-24years were recruited from female students and given one session of treadmill exercise with an intensity of 60-70% HRmax. Thiobarbituric acid reactive substance (TBARS) was used to analyze serum levels of MDA, while enzyme-linked immunosorbent assay (ELISA) was used to analyze serum levels of TNF-α and IL-6. Moreover, the independent samples t-test with a significance level of 5% was employed to have the statistical analysis. The results on 24h after treadmill exercise and delta (Δ) between CTRL and TREG showed a significant difference (p<0.001). This study found a decrease in pro-inflammatory cytokines and oxidative stress 24h after treadmill exercise in obese adolescents. Therefore, treadmill exercise can be a promising strategy for preventing adolescents from obesity as well as preventing disease risks associated with oxidative stress and chronic inflammation.
