J.Medicine & Science in Sports & Exercise: May 1998 - Volume 30 - Issue 5 - p 259 Annual Meeting Abstracts Author Information Article Outline University of Minnesota, Minneapolis (Sponsor: A.S. Leon, FACSM) Abstract 1478 The purpose of this study was to examine the acute effect of exercise on blood glucose levels in women with gestational diabetes mellitus (GDM). Thirteen women diagnosed with GDM volunteered to participate in 4 sessions. These included a submaximal cycle graded exercise test and three treatment sessions. Treatments were rest (control), and two exercise sessions on a cycle ergometer at 35% and 55% estimated ˙VO 2 max. Blood samples were obtained at baseline, and at 15 minute intervals through the 30 minute treatment session and for two hours post exercise. The figure below shows significant differences in blood glucose between rest and the 2 levels of exercise intensity and between the 2 levels of exercise. Increased exercise intensity induces greater acute changes in blood glucose and these changes disappear by 45 min post exercise.
