Rate My Professor Sean Tweedy

Professor Sean Tweedy serves as a Professor and Chair in Physical Activity and Disability in the School of Human Movement and Nutrition Sciences, Faculty of Health and Behavioural Sciences, at the University of Queensland. He leads the Para Sport and Adapted Physical Activity Research Group and is Principal Investigator for the International Paralympic Committee’s Classification Research and Development Centre (physical impairments). Tweedy holds a Bachelor of Human Movement Science, a Master's by coursework, and a PhD from the University of Queensland, where his doctoral thesis focused on promoting physical activity among community-dwelling individuals with acquired brain injury. From 1997 to 2019, he was the recipient of the Motor Accident Insurance Commission Queensland Teaching and Community Service Rehabilitation Research Fellowship in Physical Activity and Disability. In November 2025, he was appointed the inaugural NIISQ Chair in Physical Activity and Disability.

His research program addresses critical needs by developing, evaluating, and translating evidence-based interventions to increase physical activity among community-dwelling adults with disabilities, establish best-practice classification methods for Para athletes to ensure fair competition, and facilitate safe, effective participation in competitive sports for individuals with severe disabilities and high support needs, exemplified by the ParaSTART program. Notable publications include "International Paralympic Committee position stand—background and scientific principles of classification in Paralympic sport" (British Journal of Sports Medicine, 2011), "Cluster analysis of novel isometric strength measures produces a valid and evidence-based classification structure for wheelchair track racing" (British Journal of Sports Medicine, 2017), "The adapted physical activity program: A theory-driven, evidence-based physical activity intervention for people with brain impairment" (Brain Impairment, 2018), and contributions to books such as "Training and Coaching the Paralympic Athlete" (2016). Tweedy's impact is evident in the implementation of the Adapted Physical Activity Program into Queensland’s primary brain injury rehabilitation service, the adoption of the Maximum Allowable Standing Height rule by the International Paralympic Committee, and his expert testimony supporting World Athletics in the Court of Arbitration for Sport ruling on Blake Leeper’s case (2021). He also serves as a scientific advisor to World Para Athletics.
