Author's abstract

This study compared the effect of two drinks containing carbohydrates with different glycemic index and water (U1=water, U2=100 g glucose and U3=100 g fructose) on the response to performance data at rest and under exercise. The heart rate increased significantly at rest in U2, caused by an increase of catecholamines. The endurance time at maximum workload was significantly longer in U2 and U3 than in U1. The end point of the stress test was caused by exhaustion in U2 and by intestinal problems in U3. Conclusion: Glucose and Fructose have a different glycemic index which causes different effects on hormon reactions. This may be the reason for contradictory results of many studies. Drinks with low glycemic index have the best effect on exercise performance. Verf.-Referat
