The High 5 Sports Bar has been designed to contain a specific mix of both simple and complex carbohydrate. The simple carbohydrate is processed more quickly through the digestive system for absorption in the small intestine by the glucose transporters SGLT1 and GLUT2.
The complex carbohydrate then delivers a more progressive carbohydrate delivery. The 55g Sports Bar also contain 18% to 20% fructose. Recent research at Birmingham University, Glasgow University, Herts University and others has established that moderate to high fructose levels have been shown to increase the rate of exogenous carbohydrate delivery to the muscles by using the fructose transporter GLUT5 and as a result of this improved performance.
The use of multiple carbohydrate transport systems also has implications for improved Glycogen replacement post exercise (currently under research) as well as reduction in fatigue.
