We investigated whether an acute bout of moderate intensity exercise in the postprandial period attenuates the triglyceride and airway inflammatory response to a high-fat meal (HFM) compared to remaining inactive in the postprandial period. Seventeen (11M/6 F) physically active (≥150min/week of moderate-vigorous physical activity (MVPA)) subjects were randomly assigned to an exercise (EX; 60 % VO2peak) or sedentary (CON) condition after a HFM (10 kcal/kg, 63 % fat). Blood analytes and airway inflammation via exhaled nitric oxide (eNO) were measured at baseline, and 2 and 4 hours after HFM. Airway inflammation was assessed with induced sputum and cell differentials at baseline and 4 hours after HFM. Triglycerides doubled in the postprandial period (∼113 ± 18%
