Effects of a moderate glycemic meal on exercise duration and substrate utilization

Article Abstract:

Research presented concerns the impact of carbohydrate intake on blood glucose, focusing on how exercise performance is affected by a meal that rates moderately on the glycemic index. Topics addressed include glucose sparing, hepatic glucose output, carbohydrate utilization, and lipid metabolism during the exercising period.

Energy cost of activity assessed by indirect calorimetry and a (sup)13CO(sub)2 breath test

Article Abstract:

This article evaluates the accuracy of a breath test used to measure the energy costs associated with an hour of physical activity. Findings indicate that there were no significant differences in energy cost estimates obtained by the breath test and the clinically established method of indirect calorimetry.
