Richard Davison is an internationally-recognized exercise physiologist with 35+ years of academic and coaching experience. He is a Fellow of and was the President of the European College of Sport Sciences 2024 Glasgow Congress, currently a Visiting Professor of Exercise Physiology at the Mountain Bike Centre of Scotland, The School of Applied Sciences, Edinburgh Napier University, UK. He has held editorial board positions at many of the main sport science journals including the Journal of Sports Sciences, the Journal of Sport Medicine and the Journal of Science and Cycling. He is a Fellow and former Chair and Honorary Treasurer of the British Association of Sport and Exercise Sciences. He was also an editor of the BASES Physiological Testing Guidelines since 1996. He also spent 22 years working for British Cycling as a Coach Educator. Richard's expertise on cycling performance specifically and his research findings have been applied to coaching riders to win British and World Championships and compete at the Commonwealth and Olympic Games.Arthur Henrique Bossi, PhD is a lecturer and applied researcher at Edinburgh Napier University, specialising in exercise physiology and endurance performance. Over the past decade, he has combined innovative academic research with hands-on coaching and consultancy in the cycling industry. His work centres on understanding individual responses to exercise training and translating that knowledge into personalised performance interventions. Before taking up his lectureship, Dr Bossi spent more than 12 years coaching cyclists at every level, from beginners to elite mountain bikers, and served as a consultant for the Mountain Bike Centre of Scotland. This breadth of experience, spanning both the laboratory and the field, has given him a deep understanding of the cyclist-bicycle interaction and the physiological determinants of endurance performance. He brings a practical, evidence-based perspective to this book, firmly grounded in the realities of competitive cycling.
