Dose finding of OpunDiaTM (O. ficus-indica extract) for its effect on oral glucose tolerance and plasma insulin Ivo Pischel1*, Karen Van Proeyen2, Peter Hespel2 From International Society of Sports Nutrition: 9th Annual ISSN Conference and Expo Clearwater, FL, USA. 22-23 June 2012 Background High-intensity exercise typically leads to a depletion of body carbohydrate stores, primarily muscle glycogen. Therefore, typical ‘sports recovery drinks’ include a high carbohydrate dose together with proteins so as to stimulate muscle glucose uptake and glycogen resynthesis via increased plasma insulin level. In fact, any intervention that elevate plasma insulin following exercise could facilitate repletion of muscle glycogen stores, and serve as a useful ‘recovery agent’. Extracts of the prickly pear cactus (Opuntia ficus-indica; OFI) can stimulate insulin secretion [1], but the most effective dose was not yet elucidated.
Results Compared with placebo, the area under the serum insulin curve in the OGTT was significantly lower (p
