A scientific study by Professor Daniel König and his team at the Department of Sports and Sport Sciences of the University of Freiburg, Germany, has shown that with a pre-load of Palatinose, endurance athletes “maintained a more stable blood glucose profile and higher fat oxidation, which resulted in improved cycling performance compared with maltodextrin.”
Results gathered from the study highlighted that when the athletes consumed the drink containing Palatinose, they showed higher fat oxidation rates during the 90-minute endurance trial and performed better in the subsequent sprint test.
On average, the athletes finished the time trial a minute faster with the drink containing Palatinose, and were able to pedal more powerfully in the final five minutes of the time trial—compared to the maltodextrin control.
It also demonstrated that the product stabilised the blood glucose profile, with a lower blood glucose rise before exercise, and maintained this level throughout endurance exercise. As a result, a higher fat burning rate and lowered carbohydrate oxidation in energy metabolism were promoted.
Key to these metabolic improvements is the physiological properties of Palatinose. As a slow and fully available carbohydrate, it provides its energy in a more steady way, with a lower rise in blood glucose levels over longer time. These properties, as the authors explain, allow for “a greater reliance on fat oxidation and [the] sparing of glycogen during the initial endurance exercise”.
Findings illustrate that the type of carbohydrate consumed plays an important role for fuel flexibility and endurance. Sport drinks and pouches traditionally contain high glycaemic carbohydrates—such as maltodextrin or glucose—as low glycaemic, highly-tolerated carbohydrate alternatives of this quality were not available until recently.
Also, this study shows that if high fat oxidation rates are wanted or required—like basic endurance training, or key phases in competitive endurance activity—then BENEO’s Palatinose delivers advantages with its steady and sustained carbohydrate energy supply.
Anke Sentko, vice president for Regulatory Affairs and Nutrition Communication at BENEO, comments: “By improving the body’s fat oxidation capacity during high intensity exercise, it saves glycogen for the final sprint.”
“Athletes and sports people who have tried it in their daily practice report that they feel the difference. There is market demand for such sports nutrition products and the findings of this study offer food and drink manufacturers a way that they can develop products that help people achieve their sporting goals,” Ms Sentko added.
Derived from sugar beet—and also found in honey—Palatinose, like sucrose, is a fully digestible disaccharide-type carbohydrate composed of glucose and fructose. Yet, as a result of its stronger linkage, it provides carbohydrate energy in a more steady and sustained way, with less effect on blood glucose levels and insulin.
The study used a randomised, double-blind cross-over design to compare the effects of Palatinose and maltodextrin on fuel flexibility—the switch between fat and carbohydrates as an energy source and the subsequent effect on performance. It included 20 experienced cyclists who consumed 750 ml of a 10 percent carbohydrate drink each, before undertaking a 90-minute endurance exercise at moderate intensity level—60 percent VO2 max—and a subsequent time trial performance test.
