Compared to a single bolus feeding, several small feedings could produce a more modest, sustained elevation of blood glucose and insulin rather than the characteristic fluctuations of these blood constituents (Short et al., 1997). In addition, there will be lesser disturbances on the hormonal and metabolic homeostasis from frequently small carbohydrate (CHO) snacks (Jenkins et al., 1989). In other words, a significant economy in insulin secretion would be obtained when frequency of CHO feeding is increased (Jenkins, 1997). The purpose of the present study was to examine the influence of feeding pattern on postprandial blood glucose responses in endurance-trained runners at rest. Although the incremental area under the 3-hr glucose response curve in the GOR trial was similar to that in the NIB trial, the results of the present study show that the pattern in which a meal is ingested significantly impacts on the subsequent postprandial blood glucose concentration responses.
