More show notes at https://www.just-fly-sports.com/podcast-389/ Today’s podcast is with David Kerin. Dave is the USATF chair of men’s development, and also chair for men’s and women’s high jump.  Dave’s coaching career began with 14 years at the HS level followed by 14 years of collegiate coaching where an athlete set a still-standing NCAA DIII championship record in women’s high jump.   A requested speaker and published author, he is perhaps best known for his work: “What is the most direct means to achieve strength gains specific to the demands of jumping events”, as well as the popular article: “Fixing the Right Problem”.  David appeared originally back on episode #58 of the podcast in its “classic” days. Curvilinear sprinting is a critical aspect of sport movement, and is also becoming more popular in training, and for good reason.  Lateral and rotational aspects of movement are not only critical for sport, but also engage a greater fullness of the body in a training environment. On today’s podcast, David goes into the defining elements of curvilinear sprinting, and what this means, not only for track and field high jump, but athletic movements in general.  He also gets into the importance of observing and coaching athletic movement from a 3D perspective, and gives ideas on how to do so, as well as the evolution that technology is making in that direction.  Today’s podcast gives us a wonderful perspective on a more complete picture of athletic movement and performance.
