The course provides knowledge in the analysis of skeletal and cardiac cell metabolism during exercise, its regulation, and integration between muscle tissue and other organs/tissues; the course illustrates the biochemical aspects of adaptation to physical exercise, examines the use of measurable biochemical and clinical parameters in blood and urine; presents the mechanisms of genetic predisposition to motor activity.
Expected learning outcomes
Students will acquire knowledge on the various energy substrates in muscles during exercise and their metabolic regulation in skeletal muscle. Students will learn the biochemical elements of adaptation to exercise and be able to select the biochemical/clinical(molecular parameters best suited to monitoring conditions related to sports; students will learn to interpret reference biochemical-clinical data in athletes and select the methods and field instruments for dosing the parameters; student will learn the most recent anti-doping methods.
