机译：The effect of altered dietary carbohydrate content on the metabolic responses to physical exercise in insulin‐dependent diabetic subjects
The effects of two isoenergetic 8.4 MJ (2000 kcal) diets containing 40 and 65 of total energy from carbohydrate, respectively, were studied in six insulindependent diabetics in relation to the metabolic responses to physical exercise. Each subject followed both diets in turn for one week. Additionally, the effects of a pre‐exercise supplement of either 50 g carbohydrate (as glucose polymer) or placebo were measured.Exercise induced a marked fall in blood glucose levels of similar magnitude on both diets (P<0.05) in the absence of supplementary carbohydrate and a significant increase (P<0.01) when the supplement was provided. Insulin concentrations were virtually unaltered on either diet or supplement when compared before and after exercise (P<0.5).Blood levels of the gluconeogenic precursors (lactate, pyruvate, alanine and glycerol) were significantly increased after exercise in the case of both diets with or without supplementary carbohydrate (0.02展开▼
