Episode Summary
In this landmark episode of Transcending Sport, Rob Crews sits down with Bertrand Théraulaz, co-founder of ActionTypes and one of the originators of motor signature profiling.
For over 35 years, Bertrand and his partner Ralph Hippolyte have developed a comprehensive approach to understanding human movement — connecting brain, body, and behavior in ways that transform how we coach athletes.
This conversation traces the complete evolution of ActionTypes: from Bertrand's early days coaching volleyball in Switzerland, through his breakthrough discovery in 1998, to the launch of the first-ever U.S. Hybrid Training Program bringing this methodology to American coaches.
This isn't a simplified binary system — this is the complete methodology, directly from one of its creators.
Key Takeaways
🎯 You Have FOUR Motor Skills, Not One
Everyone has four motor skills available — not just one fixed profile. Your "comfort zone" is used about 70% of the time, but your second motor skill is your recovery zone. Training only one leads to overuse and injury.
🎯 Two Profiles That Interact
You have a motor profile (voluntary motor system for technique execution) AND a motivational profile (autonomous nervous system for preparation and recovery). Understanding both prevents coaching errors.
🎯 "Listen to Your Body, Not Anybody"
The body always has a solution. Your brain is a coordination device designed for movement. Trust your natural patterns instead of forcing external "one size fits all" solutions.
🎯 Coach the Intention, Not the Action
The HOW belongs to the athlete. Coaches should focus on intention and context — not prescriptive technique. "Recognize WHO they are first, not WHAT they do."
🎯 Vision Strategies Matter
Some athletes use central vision first → then peripheral. Others start peripheral → then central. You cannot teach one person the opposite strategy — it must match their profile.
🎯 The Danger of Oversimplification
Reducing motor preferences to simple binary categories is dangerous. Without understanding both profiles and all four motor skills, coaches risk causing injuries and harming athletes.
