Effects of ingesting highly branched cyclic dextrin during endurance exercise on rating of perceived exertion and blood components associated with energy metabolism

Biosci Biotechnol Biochem. 2014;78(12):2117-9. doi: 10.1080/09168451.2014.943654. Epub 2014 Jul 31.

Abstract

We compared the effect of relatively low doses (15 g) of highly branched cyclic dextrin (HBCD) with that of maltodextrin during endurance exercise on the rating of perceived exertion (RPE) in a crossover, double-blind study of healthy volunteers. The RPE increased during exercise and its increase was significantly less at 30 and 60 min after ingesting HBCD than maltodextrin.

Keywords: blood glucose; endurance exercise; highly branched cyclic dextrin; humans; rating of perceived exertion.
