Abstract
This study examined whether an acute bout of resistance exercise (RE) attenuated postprandial responses to a high fat meal (HFM) similarly in younger versus older adult men, and probed relationships among skeletal muscle mass (SMM), age, the metabolic load index (MLI) response, and the improvement in the MLI elicited by RE versus CON. Eleven younger (24 +/- 4y) and 9 older (61 +/- 5y) men completed RE or control (CON) the night prior to a HFM. Before and 1, 3, and 5 hours after the HFM, blood triglycerides (TG), glucose (GLU), MLI, and cholesterol concentrations were quantified. Following a 7 +/- 1-day washout period, participants returned and completed the opposite condition. Independent of age, TGs were 32.1 +/- 27.1 mg/dL and 52.7 +/- 26.8 mg/dL lower in RE than CON at 3 and 5 hours, respectively. MLI was also 24.3 to 56.9 mg/dL lower in RE than CON from 1 to 5 hours post-meal independent of age. The TG and MLI area under the curves (AUCs) were 15% to 31% lower in RE than CON. The GLU response was greater in the older than younger men at 1 to 5 hours post-meal. Moreover, the average GLU response was 5.6 +/- 2.5 mg/dL lower in RE versus CON and was inversely related to SMM across the sample (r = -0.615). However, age, volume, or SMM were not related to the MLIAUC, nor to the improvement elicited by RE. Therefore, although the older men displayed a greater postprandial glucose response than the younger men, RE attenuated the postprandial metabolic response to a HFM similarly in younger and older men.
