Effect of exercise mode on blood glucose disposal during physiological hyperinsulinaemia in humans

The aim of this study was to compare whole-body glucose uptake in cycling and running performed during physiological hyperinsulinaemia. On three occasions, seven male subjects underwent a hyperinsulinaemic (30 mU m(-2) min(-1)), euglycaemic (5 mmol l(-1)) clamp for 120 min. On one occasion, subjects...

description The aim of this study was to compare whole-body glucose uptake in cycling and running performed during physiological hyperinsulinaemia. On three occasions, seven male subjects underwent a hyperinsulinaemic (30 mU m(-2) min(-1)), euglycaemic (5 mmol l(-1)) clamp for 120 min. On one occasion, subjects rested for the duration of the trial (CON). On the other two occasions, after an initial resting period of 30 min, subjects either cycled (CYC) or ran (RUN) for 90 min at 65% of maximal O(2) uptake (VO(2max)). Insulin infusion resulted in physiological hyperinsulinaemia that was maintained for the duration of each trial [CON: 61 (3) mU l(-1); CYC: 77 (7) mU l(-1); RUN: 77 (5) mU l(-1)]. The rate of glucose uptake was greater during RUN than during CYC [last 30 min of exercise: 140 (4) vs 109 (8) micromol kg(-1) min(-1), respectively; P
