Disability Research Laboratory

The Disability Research Laboratory at Mississippi State University is dedicated to advancing the scientific inquiry of physical activity, physical fitness, and health in people with disabilities, especially those with Down syndrome.

Our goal is to create, disseminate, and apply scientific knowledge for enhancing meaningful physical activity participation and reducing health disparities in individuals with disabilities. Our research is interdisciplinary, and members of our laboratory pursue research in five main areas:

1. Measurement of physical activity and sedentary behavior
2. Levels, patterns, and development of physical activity and sedentary behavior
3. Determinants of physical activity and sedentary behavior
4. Consequences of physical activity and sedentary behavior
5. Interventions for improving physical activity and health

This website includes information on our research team, collaborators, research projects, and publications.

Laboratory Director

Dr. Stamatis Agiovlasitis

I am a Professor in Kinesiology at Mississippi State University.  I am also Fellow of the American College of Sports Medicine, Associate Editor for the Adapted Physical Activity Quarterly, and Past President of the North American Federation of Adapted Physical Activity.  My goal is to contribute through academic scholarship to a society where individuals experiencing disability are empowered to participate in meaningful physical activity opportunities and to achieve optimal health.   

I have a long history of research that concentrates on physical activity, physical fitness, and health in people with disabilities, particularly those with Down syndrome.  My research viewpoint is holistic—I am interested in movement patterns, physiological responses and adaptations, health behaviors, and health outcomes, as well as the design and delivery of programs for acquiring healthy behaviors.  My research is therefore inter-disciplinary.  And, although it focuses on individuals with Down syndrome, it has lessons and implications for people living with intellectual or physical impairments.

What motivates me to pursue my scholarly activities is learning.  If learning in this area of scholarship is what motivates you too and if you wanted to either collaborate with me or study under my mentoring, I would be happy to discuss possible opportunities with you.
