Effect of Carbohydrate Ingestion on Sprint Performance Following Continuous Exercise

The purpose of this study was to determine the effect of 5% carbohydrate ingestion on the sprint performance immediately following 90 min of running at 70-80% of maximal heart rate reserve. Thirty young active men were selected as subjects and allocated randomly to two carbohydrate (CHO, N = 15) and placebo (PL, N = 15) groups. Pre-test 200 m dash, 90 min running and post-test 200 m dash took place, respectively. Exercise heart rate monitored during 90 min running by a cardio frequency meter. Significant differences were found between the CHO and PL post-test 200 m dash records (p<0.05). Blood glucose was found to be significantly higher at the end of the 90 min running for the CHO group than for the PL group (p
