| Summary: | Obesity is associated with elevated levels of the pro-inflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), contributing to systemic insulin resistance. Fibroblast growth factor 21 (FGF21) is a vital metabolic and inflammatory regulator, however circulating FGF21 concentrations are elevated in obese individuals. Acute aerobic exercise increases systemic FGF21 in normal-weight individuals, however the effect of acute aerobic exercise on plasma FGF21 response and the relationships with inflammation (IL-6 and TNF-α), insulin resistance, and energy expenditure in obese individuals is unknown. Following 30 minutes of treadmill running at 75% VO2max, plasma FGF21 response, as indicated by area-under-the-curve “with respect to increase” (AUCi) analyses, was attenuated in 12 obese compared to 12 normalweight subjects. Additionally, FGF21 AUCi positively correlated with glucose AUCi, total relative energy expenditure, and relative VO2max, suggesting that cardiorespiratory fitness levels may predict FGF21 response, contributing to the enhanced regulation of glucose and energy metabolism. | |
