Biography

Professor Julien Baker has investigated the mechanical and pharmacological aspects of strength and power. This work has identified serious errors in the measurement of power using the Monark cycle ergometer and is emphasising the need for a new and more accurate approach to this challenge. 

The influence of the work conducted by Professor Baker and his colleagues which identified the need to account for fat-free mass and the significant involvement of the arms in the ergometric assessment of power, work output and efficiency, has been substantial. These findings have outlined the considerable differences in haematological, hormonal and biochemical changes in acute and long term exercise when the correct morphological and physiological considerations are considered. Professor Baker’s current research interests include the use of high intensity exercise models in the management of cardiovascular disease, diabetes and obesity. The models have been used extensively in both children and adolescent populations. In recognition of his research achievements, Professor Baker has been appointed to the editorial board of several UK and international journals and is a former Director of Research for the Welsh Institute of Sport, Health and Exercise Science (http://www.wishes-cymru.org/index.html). 

Professor Baker and colleagues have investigated anabolic steroid users who were supplementing their androgen regimen with insulin and growth hormone. They also identified a large number of recreational gym users who use pharmacological substances. Working with the National Drug Testing Centre, King’s College London (Professor Cowan and Dr Kicman), this initial finding provided the Group with a unique opportunity to monitor the physiological and biochemical implications of this performance-enhancing drug regimen and remains, to the best of our knowledge, the first of its kind. This research has attracted the attention of the international scientific community and the interest in Wales and Scotland has been widespread as evidenced by the involvement of Group members in many radio and national television programmes. Particular concern was voiced by members of the Welsh Assembly Government and, as a consequence, we are currently involved in a process that will identify strategies aimed at counteracting this kind of drug abuse. 

Professor Baker is a member of the Physiological societies of Britain and USA.
