SPORT, EXERCISE & HEALTH SCIENCE Sport, Exercise & Health Science

By studying SEHS, students explore what it means to thrive in terms of physical activity, athletic performance and personal health. Uniquely among the sciences, the course has immediate everyday applicability outside the classroom as pupils can apply what they have learned to their daily lives, positively impacting their personal health and sporting performance. Excelling in sports requires a mixture of innate ability and the dedicated pursuit of self improvement. Sporting excellence is best achieved through a planned, incremental, long-term program of physical and mental training and skills development. This also needs to be accompanied by appropriate nutrition, rest and sleep. Planning such a program is the role of the sports, exercise and health scientist. The design of a training program requires careful consideration of the physiological, biomechanical and psychological demands of the individual and the activity they will be involved in. Through the lenses of both health and performance, students can apply the knowledge and skills they develop in this course to their own sporting endeavors, as well as applying these to their broader community. In a world where millions are physically inactive and afflicted by chronic disease and ill health, the sports, exercise and health scientist can be as proficient in prescribing exercise for general health and well-being as they can be in prescribing it for an aspiring athlete. The course is divided into three themes, each explored in the context of both health and performance. In Exercise physiology pupils will gain knowledge and understanding of three subtopics: communication of body systems; hydration and nutrition; and training and recovery. They may explore guiding questions such as: “How does the body send and receive information about its internal environment to maintain optimal functioning conditions?” In Biomechanics, pupils investigate three subtopics: generating movement in the body; forces, motion and movement; and injury. Guiding questions include: “How are the structures and functions of the musculoskeletal system related to movement of the human body?” The third theme is Sports psychology and motor learning, in which pupils explore five subtopics: individual differences; motor learning; motivation; stress and coping; and psychological skills. Guiding questions include: “What are the psychological processes that drive human behaviour, and how can these be influenced?” and “How are skills acquired, practised and perfected?” The SL course provides students with a fundamental understanding of SEHS and experience of the associated skills. The HL course requires students to increase their knowledge and understanding of the subject, and so provides a solid foundation for further study at university level.
