Biography

Stuart graduated in Physiology and Sports Science from the University of Glasgow before undertaking a PhD entitled "Temperature and in vivo human skeletal muscle function and metabolism" at the University of Strathclyde(2007). During his doctoral studies Stuart was awarded the Pfizer Prize from the Physiological Society in 2005. Stuart remained at the University of Strathclyde as a Post-Doctoral Research Fellow before moving to Loughborough University to take up a Senior Research-Associate position. Stuart joined the institute of medical sciences in November 2008 as a Lecturer in Exercise Physiology.

Research Interests

 

Stuart's main area of interest is in the loss of muscle that occurs as we age. With age there is a natural loss of muscle mass that is termed sarcopenia and this can have major effects on physical function and quality of life in the elderly. The precise cause of the loss of muscle mass is not yet known, but we do know that elderly muscles exhibit an anabolic resistance to exercise and food intake. We are currently carrying out several studies investigating the efficacy of nutritional supplementation (i.e. n-3 PUFAs) in overcoming this anabolic resistance in older people. We are supplementing these human studies with mechanistic studies in cell culture.

Outreach activities

I have recently acted as a mentor for secondary school pupils taking part in the "Science of Sport: How to Win Gold" competition organised by the Physiological Society. I also recently participated in i'm a scientist get me out of here, where we had online chats with primary school kids who then decided whether we our responses merit their votes. I did not win!
