In the increasingly competitive world of elite sport, understanding the factors that limit human performance is critical as athletes push their bodies to the limit to achieve incredible performances that we can only dream of. Over the last 30 years as technology has developed we are now able to quantify, examine, simulate and optimise human performance. This presentation will explore the factors that limit human performance using examples from a range of sports including gymnastics, cricket, tennis and badminton. BIOGRAPHY Mark King is a Professor of Sports Biomechanics at Loughborough University and a Fellow of the International Society of Biomechanics in Sports. His research combines theoretical and experimental techniques in biomechanics to explore and push the boundaries around optimum performance in sport.
