Timothy Bryan Hartwig

Timothy Bryan Hartwig is a Senior Lecturer at the School of Behavioural and Health Sciences, specializing in sports science and public health. His research focuses on youth physical activity interventions, injury prevention, and performance optimization in adolescents.

Education: Completed a thesis on 'Training and competition demands of adolescent rugby union players' (2009).

Research highlights include meta-analyses on 24-hour movement behaviors for obesity management and scalable school-based interventions. He collaborates internationally on studies involving over 9,800 participants across seven countries. His work spans sports nutrition (e.g., low-carb diets in athletes), injury risk factors in contact sports, and implementation of physical activity programs in schools. Hartwig has contributed to both experimental designs and observational studies, with methodologies including GPS tracking and randomized controlled trials.

His articles consistently address health equity in physical activity interventions and the physiological challenges facing youth athletes during maturation phases.
