Nick Draper has been a researcher and teacher at the University of Canterbury, New Zealand, for more than a decade but has a wealth of experience developed as a practitioner. Nick’s research has a translational focus, with the aim of finding solutions to real-world problems. Nick completed his research training at the Universities of London and New Mexico, where he received a thorough grounding in qualitative and quantitative methods, both of which he applies to research problems in his chosen field of exercise physiology. Craig A. Williams is the director of the Children’s Health and Exercise Research Centre (CHERC), Devon, UK. He lectures on the physiological aspects of the BSc and MSc degree programmes at the University of Exeter. He is internationally recognised for research in paediatric exercise physiology. Professor Williams specialises in investigating the physiological responses to high-intensity exercise and fatigue in children and adolescents (6–18 years). This work is translated into clinical settings, for example, children with cystic fibrosis and congenital heart disease, as well as applied youth sports performance (particularly in relation to the long-term development of young athletes). Helen Marshall, PhD, is a team leader and the health promotion degree coordinator at Ara Institute of Canterbury, New Zealand. Her main teaching focus is around the multiple ways by which people can be enabled to take control of their health, while her collaborative research has specifically focussed on the many health benefits of physical activity for a variety of populations.
