Abstract

BOUCHARD3 GlK 7P4 EXERCISE TRAINING is recommended as an important adjunct in the treatment of excess body weight related metabolic complications. Regular exercise helps to induce a balance has the potential to enhance in vivo action. A large body of literature (reviewed in Ref. 28) indicates that exercise training is associated with decreased plasma concentrations together with unchanged or improved glucose tolerance, suggesting increased sensitivity; the increased sensitivity with training has been shown in several studies by use of the euglycemic-hyperemic clamp procedure. However, the deficit, more especially the effect on sensitivity of exercise, could be offset by an increased ( carbohydrates) intake in the immediate postexercise period, as observed in some trained lean subjects (8, 34). Therefore, to assess the specific influence of regular exercise on plasma E248 0193-1849/97 $5.00 Copyright o sensitivity, one should ideally keep macronutrient intake constant for the duration of the exercise protocol. This requirement seems difficult to meet in free-living individuals, few long-term studies have been reported on this subject. In a previously reported experiment (6,32), the feasibility of such a protocol was, however, demonstrated in five young men submitted to a loo-day exercise training protocol on constant intake.
