The effect of 5% sucrose consumption on blood glucose and maximum sprint performance during 90 min endurance running.

Introduction and In recent years, carbohydrate consumption has become more prevalent during endurance exercise. The purpose of this study was to determine the effect of5% sucrose consumption on blood glucose and maximum sprint performance (200 m) followed by 90 min endurance running. 30 young male athletes (age: 21.28 1.43 years, height: 175.42606 cm, weight: 69.28.32 kg) were selected as the subjects and allocated randomly to the Carbohydrate (CHO) (N = 15) and the Placebo (PL) (N=15) groups. Pre-test 200 m dash, 90 min running and post-test 200 m dash took place, respectively. CHO group consumed a 5% sucrose solution at regular 15 minute intervals, while the PL group consumed Placebo during exercise. Sprint performances as well as the blood glucose were measured during the trials. Post test Sprint performance was found to be significantly lower in the CHO group than the PL group (P 0.05). Blood glucose was found to be significantly higher in the CHOgroup than the PL group (P 0.05).Discussion and The result suggests that carbohydrate consumption during endurance exercise inhibits that failure of sprint performance and blood glucose of young active men.
