Abstract
The consumption of a high-fat meal can induce postprandial lipemia and endothelial dysfunction. The authors assessed the impact of age and physical activity on metabolic and vascular outcomes following meal consumption in healthy adults. The authors recruited four groups: younger active (age 22.1 +/- 1.4 years; n = 9), younger inactive (age 22.6 +/- 3.7 years; n = 8), older active (age 68.4 +/- 7.7 years; n = 8), and older inactive (age 67.7 +/- 7.2 years; n = 7). The metabolic outcomes were measured at the baseline and hourly for 6 hr post high-fat meal consumption (12 kcal/kg; 63% fat). Flow-mediated dilation was measured at the baseline, 2 hr, and 4 hr postmeal. The total area under the curve for triglycerides was significantly lower in the more active groups, but did not differ based on age (younger active = 6.5 +/- 1.4 mmol/L x 6 hr, younger inactive = 11.7 +/- 4.8, older active = 6.8 +/- 2.7, older inactive = 12.1 +/- 1.7; p = .0004). After adjusting for artery diameter, flow-mediated dilation differed between groups at the baseline (younger active = 4.8 +/- 1.6%, younger inactive = 2.5 +/- 0.5, older active = 3.4 +/- 0.9, older inactive = 2.2 +/- 0.4; p < .001) and decreased significantly across groups 4 hr postmeal (mean difference = 0.82; 95% CI [0.02, 1.6]; p = .0 4) . These findings highlight the beneficial effect of regular physical activity on postprandial lipemia, independent of age.
