Slow postmeal walking reduces postprandial glycemia in middle-aged women.
Postpr and ial blood glucose concentration is a risk factor for the development of cardiovascular diseases and diabetes , even at states well below hyperglycemic levels . A previous study has shown that postmeal exercise of moderate intensity blunts the blood glucose increase after carbohydrate intake ( Høstmark et al. Prev . Med . 42(5 ) : 369 - 371 ) . The objective of the present study was to examine whether even postmeal slow walking would have a similar effect . Fourteen healthy women aged > 50 years participated in 3 experiments in a r and om crossover design : after a carbohydrate-rich meal , either they were seated ( control experiment ) or they performed slow postmeal walking for 15 min ( W15 ) or 40 min ( W40 ) . Blood glucose concentration was determined prior to the meal ( fasting ) , and at 11 time points throughout each experiment . The W15 trial lowered the blood glucose values during walking and delayed the peak blood glucose value ( p = 0.003 ) . In W40 , the postmeal blood glucose increase during walking was blunted , the peak glucose value was delayed ( p = 0.001 ) , and the incremental area under the 2-h blood glucose curve ( IAUC ) was reduced ( p = 0.014 ) . There was a negative relationship between IAUC and walking time ( p = 0.016 ) . The individual reducing effect of walking on IAUC correlated strongly with IAUC on the control day ( p < 0.001 ) . We conclude that even slow postmeal walking can reduce the blood glucose response to a carbohydrate-rich meal . The magnitude of this effect seems to be related to the duration of walking and to the magnitude of the postpr and ial blood glucose response when resting after a carbohydrate-rich meal
