Athletic Performance
Conditions
Brief summary
Endurance sport is often characterized by high training loads and significant metabolic demands, including depletion of endogenous fuel stores (e.g. liver and muscle glycogen) and damage to the skeletal muscle proteins. Nutritional interventions that enhance the restoration of endogenous fuel stores and improve muscle damage repair have received a lot of attention. The primary aim of this project is to clinically test the effect of alginate encapsulation technology on performance. Furthermore, we will investigate the substrate utilization profile during exercise and subsequent recovery. The encapsulation technology presents a nutrient delivery solution, which results in a sustained or slow-release of the nutrients encapsulated. Thus, potentially optimizing the digestion and absorption by promoting an easy ingestion of high concentrations of fx carbohydrates without negatively affecting the gastrointestinal comfort.
