Different energy sources in sports: Introductory software

This work describes software designed to promote the association between the content of a basic undergraduate biochemistry course and the professional activities of physical education students. The software contains three main content sections: (A) Structure of skeletal muscle, (B) Contraction mechanism, and (C) Adaptations to physical exercise. A fourth section asks questions of the students. The software offers students a brief introduction on muscle structure and function, focusing on the energy sources required by different kinds of physical activities. The software was field tested at Universidade Estadual de Campinas (Unicamp), Brazil and has been adopted by several Brazilian universities. The students are required to examine the software, to discuss its contents, and to produce a list of questions arising from their work with the software. These questions are answered during the development of the curriculum, thereby connecting biochemical knowledge with the energetic needs for the practice of sports.
