Researcher biography

Sean has two primary research interests in the field of physical activity and disability:

1. Increasing physically active behaviour among people with disabilities : The health benefit of physical activity for the general population is well established and research indicates that the health benefit of physical activity for people with disabilities is likely to be even greater than it is for the general population. However there is very little research that evaluates whether we can successfully encourage people with disabilities who are sedentary to become physically active. Evaluating the efficacy of interventions that aim to promote adoption and maintenance of physical activity among people with disabilities, particularly those in post-acute rehabilitation, is a principal area of interest for Sean. This line of research is one of many that is greatly enhanced by access to the mobile exercise science laboratory.

2. Development and evaluation of classification systems in disability sport : The purpose of classification is to facilitate fair competition among athletes with disabilities by minimising the influence of impairment on the outcome of events (i.e., to ensure an athlete is not precluded from success simply because they are more disabled other competitors). Systems of classification that are scientifically and taxonomically sound are critical for all levels of disability sport, encouraging participation among novices and ensuring the integrity of competition at the elite level. Sean is currently conducting a research project in this area that is funded by the Australian Sports Commission.


Sean Tweedy has held the CONROD Research Fellowship in Physical Activity and Disability in the school of Human Movement Studies since 1997. In his role he conducts a teaching, research and community service programme in adapted physical activity. Prior to 1997 Sean worked as an exercise physiologist for the Sporting Wheelies and Disabled Association (1985-95) and ran the talent identification programme for the Queensland Academy of Sport (1995-97).

He completed his Masters degree part-time (1993-96), investigating the effects of a resistance training intervention on adolescents with cerebral palsy. Sean completed his PhD in 2006, entitled Promoting physical activity among community-dwelling people with acquired brain injury. He runs the Adapted Physical Activity Program which is a community-based program that assists people with disabilities to become more physically active.
