Biography
Dr. Grant Tomkinson has a Bachelor of Sports Science (Exercise Science) degree from the University of New South Wales, and a Bachelor of Applied Science (Honours) degree and a Doctorate (Ph.D.) in Human Movement from the University of South Australia (UniSA). He is a Professor in the Department of Kinesiology and Public Health Education at the University of North Dakota (UND), and an Adjunct Professor with the School of Health Sciences at UniSA. He is the Associate Editor for the Journal of Exercise Science & Fitness, the former Chair of Active Healthy Kids Australia (AHKA), and the former Asia-Pacific Lead for the Active Healthy Kids Global Alliance (AHKGA). He was the Project Leader for the US$690,000 million Anthropometric Survey of the Royal Australian Navy (ASRAN) and for the US$830,000 Australian Warfighter Anthropometric Survey (AWAS).
His research interests include temporal trends in the physical fitness, physical activity, and adiposity of young people, and anthropometry, with a particular focus on 3D anthropometry and the digit ratio. He has 94 refereed publications, has delivered 46 invited/keynote scientific presentations in 10 countries, and has won US$3.9 million in research funding. Using historical data on over 75 million young people from 50 countries, his research was the first to conclusively show that young people’s aerobic fitness has, in fact, declined worldwide since about 1975 and has plateaued (in high-income countries) since 2000. His research has informed policy at an international level, with contributions to policy in Australia, Canada, France, and the United Kingdom, and to the International Olympic Committee’s consensus statement on Fitness and Health of Young People through Sport and Physical Activity. He is a Young Tall Poppy Science Award winner.
