Llion began his research training at John Moores University, Liverpool, UK; before moving to The University of Queensland in 2011 to undertake his PhD in sports physiology. He specifically examined the physiological, mechanistic and applied effects of cold water immersion after strength exercise; and the acute Vs chronic implications of its use. His research interests lie with understanding the basic physiological and mechanistic responses to exercise bouts, and how they can be manipulated to maximize training adaptation per se, and in athletes. After his PhD, Llion has continued this line of research, examining the mechanistic, physiological and applied aspects of recovery and intervention therapies including heat, nutraceutical supplementation; and more recently, blood flow restricted exercise.
