Background: A single high-fat meal (HFM) is known to elevate blood lipid levels above what is normal, resulting in postprandial lipemia (PPL). Chronic hyperlipemia has been associated with increased risk for cardiovascular disease (CVD) and type-2 diabetes mellitus (T2DM) development. Current physical activity (PA) guidelines recommend at least one set of 8-12 repetitions of each exercise to attenuate this risk. Adults older than 50 (OF) years (y) are at an increased risk for cardiometabolic disease compared to younger adults (YA). Aerobic exercise (AE) performed in the pre-prandial period has been observed to attenuate PPL in both OF and YA. However, the effect of postprandial exercise on PPL is less congruent. Resistance exercise (RE) has been less extensively studied, but similar attenuations have been observed as AE in some studies. Therefore, the effect of an acute bout of RE that meets PA guidelines performed before and after a HFM on PPL in adults 50-80 y was examined. Methods: Eleven adults 50-80 y visited the laboratory in a random order to complete an HFM with no exercise (HMF), exercise before HFM consumption (HFM+ EX BEF), and exercise after HFM consumption (HFM + EX AFT). Fasting blood samples and postprandial blood samples (minute 30, 60, 90, 120, 180, 240) were obtained. A repeated measures ANOVA (time*condition) was utilized. Results: Postprandial lipemia was not attenuated with exercise. There was a significant elevation of triglycerides (TG) in the HFM + EX AFT compared to the HFM condition. Conclusions: TG concentrations were elevated in the HFM + EX AFT condition compared to HFM alone. Pre-prandial exercise did not attenuate PPTG. Therefore, a bout of resistance exercise that meets minimum PA guidelines does not attenuate PPL.
