Learning outcomes

The students will acquire knowledge relating to modifications of cardio-circulatory, respiratory and metabolic muscle parameters, in athletes engaged in different sports and at different levels. It will be studied the quantifiable factors affecting the performance. In particular, it will be examined the role of biomechanical and physiological factors in different sports competitions. The student will be able to formulate physiological models in order to predict the performance. The course aims to deepen the bioenergetics of locomotion models and the concept of energy cost of locomotion (C), particularly interesting in sports (running, swimming and cycling). The main factors changing the energy cost of locomotion and limiting the performance will be described. Subsequently physiological models will be developed to predict performance of some kind of competitions at different distances. It will be analyzed models to quantify the weight of the physiological factors affecting performance. The main adaptations induced by training on the cardiovascular, respiratory and muscular system will be learnt. Finally, further knowledge will be provided students to understanding the phenomena of plasticity of skeletal muscle and of the nervous system during the physical training.
