Research at Leeds Beckett
Professor John O'Hara
About Professor John O'Hara
John O'Hara is a Professor in Sport and Exercise Physiology. His research interests are in the area of sport performance, including: carbohydrate metabolism; physiological changes at high altitude; hydration status; global position tracking.
John completed his first degree in Sport and Exercise Science, followed by a Masters in Sport and Exercise Science at Leeds Beckett University. He then went on to complete his PhD with Professor Roderick King at Leeds Beckett University. His PhD studies focussed on pre-exercise carbohydrate ingestion: rebound hypoglycaemia, fuel utilisation and endurance capacity in male cyclists.
John has worked at Leeds Beckett University as an academic member of staff since 2000, becoming a Professor in Sport and Exercise Physiology in 2015. John is a local research ethics co-ordinator and is a co-opted member to the University research ethics committee. John acts as a research mentor to academic colleagues. Further he delivers on physiology and nutrition modules at under-graduate and post-graduate level, as well as supervising PhD students within the Carnegie School of Sport. He is a Senior Fellow of the Higher Education Academy.
John is an accredited sport scientist with the British Association of Sport and Exercise Sciences (BASES), as well as being a Chartered Scientist with the Science Council. He also acts as the Director of the physiology research laboratories within the Carnegie School of Sport. John is an experienced applied sport scientist having worked with amateur and professional athletes across a range of sporting disciplines for many years.
- PhD Supervisor and Director of Studies
- Delivers on physiology and nutrition modules across the sport and exercise science under-graduate and post-graduate provision within the Carnegie School of Sport.
John is involved in research related to carbohydrate metabolism, supervising several PhD students. He was awarded a "Promising Research Fellowship" by Leeds Beckett University (February 2011 to June 2011), which provides an opportunity to develop the use of 13C stable mass isotopes within our carbohydrate metabolism research. These techniques allow the quantification of exogenous and endogenous (muscle and liver) carbohydrate oxidation during exercise and are now used routinely within our research.
John is collaborating with researchers from the Defence Medical Service (DMS) hypoxic study group on a number of projects related to physiological changes at high altitude. He is currently undertaking research projects with the DMS, investigating the effects of high altitude exposure on carbohydrate metabolism, as well as hormonal responses in relation to acute mountain sickness.
John is also leading research assessing the movement and physiological demands of Rugby League referees within the European Super League.
John has also used his research expertise to secure funding from commercial companies to carry out research or product development.
