THE ESSENTIALS OF PERFORMANCE ANALYSIS What is performance analysis and how does its use benefit sports performance? How can you use performance analysis in your sport? The Essentials of Performance Analysis answers your questions, providing a complete guide to the foundational elements of match and performance analysis for new students and beginners. As well as a basic introduction to the sport science and theory that underlies performance analysis, the book contains many practical examples to show per- formance analysis in its applied context. It includes discussion of: approaches to analysing sport performance the use of feedback technologies the use of video and biomechanical analysis interpreting data coaching with notational analysis The Essentials of Performance Analysis is a straightforward, concise and authorita- tive guide for students of sport science and sports coaching, as well as for coaches and athletes looking to develop their insight into sports performance analysis. Mike Hughes is Professor and Head of the Centre for Performance Analysis and Course Director of the Masters in Performance Analysis at the University of Wales Institute, Cardiff. Ian M. Franks is Professor and Director of the Motor Control and Learning Laboratory, University of British Columbia, Vancouver.
