Dr. Brendan O'Brien
Associate Professor, Sport & Exercise Physiology
Dr Brendan O'Brien is a Senior Lecturer in exercise physiology and exercise prescription at Federation University Australia.
Dr Brendan O'Brien’s current research interest is in optimisation of exercise prescription based on individual differences in physiology. In particular, Brendan is focusing on identifying reliable and sensitive physiological biomarkers that can predict the “trainability” of individuals to endurance and resistance training.
Brendan has published over 40 journal articles in Exercise Physiology. Brendan has a background in sport science and has published articles relating to cycling, Australian rules, football, tennis, netball, badminton and endurance running. He also has an extensive publication history on the impact of exercise on white blood cell telomere regulation and the epigenome.
Brendan is an accredited Exercise Scientist with Exercise Sport Science Australia. He has supervised five PhD students and eight Masters students to completion.
