Ian Renshaw: I dedicate this book to all those teachers and coaches who selflessly give so much of themselves to others.

Keith Davids: Thanks to all the sports practitioners who have adopted an ecological dynamics rationale to underpin their constraints-based approach. A special thanks to all those who have shared, and who continue to develop and share, their most invaluable experiential knowledge. Your input and open minds are invaluable and a source of inspiration as we seek ways to help individuals realise their potential, improving the learning experiences of athletes at all performance levels.

Danny Newcombe: I would like to thank all of the coaches, players, coach developers and academics who I have been lucky enough to learn and develop with. Long may the conversations continue.

Will Roberts: Thank you to all the academics, coaches, athletes and students that have been, and continue to be, the cornerstone of my own learning journey. I have been fortunate to have been inspired, influenced, challenged and supported by you all.
