476: Kathy Sierra on Movement Mastery in Horses, Humans, and Robots

More show notes at https://www.just-fly-sports.com/podcast-476/ Today’s guest is Kathy Sierra. Kathy Sierra is a computer scientist, author, and horse-movement innovator who bridges neuroscience, learning psychology, and equine training. Co-creator of the award-winning Head First programming series and founder of the JavaRanch community, she later turned her expertise in intrinsic motivation toward her lifelong passion for horses. Through her Panther Flow approach, Kathy helps horses and riders unlock confident, curious, and expressive movement, sharing her work worldwide through courses, workshops, and writing. In training and movement, drilling “perfect form” is standard practice. The more we get into how humans learn, the more we realize that “perfect form” is a myth, and learning is a far more complex venture. Using both differential learning (variety) and constraints helps athletes hone in on their own optimal (and robust) technique, without needing to constantly be looking for one “perfect” way to do things. This is not only true in animals, but also in humans and in machine learning. On this week’s episode, Kathy covers aspects of training horses using the same motor learning concepts that work best in humans. She also goes into how and why robots learn to move better based on constraints, trial and error, versus a “perfect technique” type of programming. This is a fascinating and wide-ranging discussion on human movement, learning, and sport skill. Today’s episode is brought to you by Hammer Strength.
