PURPOSE: We systematically investigated the effects of different exercise strategies on postprandial glycemia.

METHODS: Six randomized repeated-measures crossover studies were performed. Study 1 compared the effects of 60 min of brisk walking started at 30, 60 or 90 min after breakfast on post-breakfast and post-lunch glycemic responses. Study 2 investigated the effects of 30 min of different exercise types (aerobic vs. resistance vs. combined). Study 3 compared the effects of 30 min of different aerobic exercise types (walking vs. cycling vs. elliptical). Study 4 evaluated the effects of 30 min of brisk walking performed 45 min before, or 15 and 30 min after breakfast. Study 5 compared 30 with 45 min of postprandial brisk walking. Study 6 compared the effects of a total of 30-min brisk walking exercise fragmented in bouts of 15, 5 or 2.5 min performed every 15 min.

RESULTS: Postprandial but not pre-prandial exercise improved glycemic response (Studies 1 and 4). The glycemic peak was attenuated only when exercise started 15 min after the meal (Study 4). A similar reduction of the postprandial glycemic response was observed with different exercise types (Studies 2 and 3). Thirty and 45 min of brisk walking provided a similar reduction of the postprandial glucose response (Study 5). When performing activity breaks, 10 and 20 min of cumulative exercise were sufficient to attenuate postprandial glycemia in the first-hour post-meal (Study 6).

CONCLUSION: Our findings provide insight into how to choose timing, type, duration, and modality for postprandial exercise prescription in healthy individuals.
