Very light Physical Activity after a Meal Blunts the Rise in Blood Glucose and Insulin~!2008-06-11~!2008-10-16~!2008-11-28~!

Abstract

The objective of this study was to examine the impact of post-meal light exercise on the rise in blood glucose and insulin. After fasting overnight, nine healthy subjects (age 37.3 ± 12.2 years) participated in three experiments in a crossover design: Day 1 (no exercise), the subjects were given cornflakes, and blood glucose and plasma insulin were determined before meal, and each 15 min for the next 165 min. Day 2 and 3 were similar to Day 1, but included 30 min very light and light intensity bicycle exercise after the meal. Both levels of exercise blunted and delayed the rise in blood glucose and plasma insulin. Bicycling-related reductions in peak glucose and insulin values correlated with peak values the control day (r =-0.83 to-0.93, P 0.006), as did reductions in AUC and IAUC. We conclude that even very light exercise after a carbohydrate meal blunts the rise in blood glucose and insulin.

Slow postmeal walking reduces postprandial glycemia in middle-aged women

“…This would suggest that the duration of postmeal physical activity may be at least as important as the intensity in lowering postprandial glycemia. This suggestion is in accordance with a recent study by Aadland and Høstmark (2008) on healthy subjects, and is consistent with the recommendations of Galbo, Tobin, and van Loon (Galbo et al 2007) in those with type 2 diabetes, that overall energy expenditure, rather than peak exercise intensity, is the primary determinant for reduction in postprandial blood glucose and insulin with physical activity.…”

“…Thus, it would seem that subjects most in need of lowering postprandial glycemia are also those obtaining the greatest blood glucose reduction when walking after a carbohydrate-rich meal. Previously, similar observations were made when comparing the postprandial glycemia after intake of high-glycemic vs. low-glycemic carbohydrates (Høstmark 2007), and in the exercise study of Aadland and Høstmark (2008).…”

Intervention Effects on Physical Activity and Insulin Levels in Men of Pakistani Origin Living in Oslo: A Randomised Controlled Trial

“…Long-term exercise studies have been shown to be relatively effective in reducing the postprandial insulin load [32–34]. Furthermore, even very light post-meal physical activity may blunt the postprandial blood glucose increase [35]. Additionally, a single session of strength exercise reduced the blood glucose response to carbohydrate intake 24 h later [36].…”

Long-term effects of daily postprandial physical activity on blood glucose: a randomized controlled trial

“…However, the timing between food ingestion and exercise affects the acute influence of exercise on postprandial glycemia, with the most pronounced effect observed when physical activity is performed short time after food ingestion (Aadland and Høstmark 2008;Bailey and Locke 2015;Caron et al 1982;Colberg et al 2014;Dipietro et al 2013;Dunstan et al 2012;Gillen et al 2012;Hashimoto et al 2013;Hostmark et al 2006;Larsen et al 1997;Larsen et al 1999;Lunde et al 2012;Nelson et al 1982;Nygaard et al 2009;van Dijk et al 2013a). Even very light or small amounts of postprandial physical activity have the ability to blunt postprandial increases in glycemia effectively (Aadland and Høstmark 2008;Bailey and Locke 2015;Dipietro et al 2013;Dunstan et al 2012;Lunde et al 2012;Nygaard et al 2009;van Dijk et al 2013a). However, little is known about the long-term effect of such activity.…”

“…The intervention was "home-based", and they were free to do whatever type of activity they wanted, as long as it involved the legs. Prior to target-setting they were given information about the acute effects of postprandial physical activity on blood glucose (Aadland and D r a f t Høstmark 2008;Caron et al 1982;Colberg et al 2014;Colberg et al 2009;Derave et al 2007;Dipietro et al 2013;Dunstan et al 2012;Hashimoto et al 2013;Hostmark et al 2006;Larsen et al 1997;Larsen et al 1999;Lunde et al 2012;Nelson et al 1982;Nygaard et al 2009;Peddie et al 2013;van Dijk et al 2013a). They were free to choose which of the daily meals that should be followed by physical activity, but they were informed that the effect was anticipated to be largest after meals with largest carbohydrate intake.…”
