• SR-257 Kinanthropometry

  The purpose of this module is: (i) to develop knowledge of the rationale, theoretical basis and methodology of Kinanthropometry and body composition assessment; (ii) to develop practical skills and confidence in performing kinanthropometric and body composition measurements, and in interpreting the data obtained, (iii) to develop an appreciation of the validity of differing techniques in special populations, including athletes and children.

• SR-367 Exercise, Growth and Development

  This module will explore the central tenet that chlidren are not mini-adults and that we can't simply assume their response to exercise and training is a scaled down version of that observed in adults. Indeed, youth are a unique group in which we must distinguish effects of external stimuli such as training from the simultaneous effects of growth and maturation. As we continue to face the global obesity and physical inactivity epidemic, understanding the physiological, psychological and behavioural underpinnings that determine sports performance and participation and physical activity is of ever greater importance. This module will provide an in depth insight into our current understanding of these issues in healthy children and those with chronic disease.
