Learning objectives
The course provides knowledge on the importance of nutritional status for maintaining an organism healthy and able to meet the energy demands of physical activity. Nutritional regimens for adequate nutrient supply based on the classification of sports and the risks and benefits of supplementation will be examined. The principles underpinning the methods for assessing nutritional status and needs of the population and the individual will be analyzed.
Expected learning outcomes
Students will acquire the necessary skills to assess: 1) adequate energy supply, correct distribution and timing of nutrient intake according to nutritional regimens for athletes during training, competition, and recovery; 2) appropriate use of dietary supplements and their mechanisms of action. Students will acquire knowledge about guidelines for a healthy, correct diet, different types of diets, and adjustments for athletes with special dietary needs (celiac disease, vegan).
