415: Andrew Sheaff on Constraints and the Art of Individualized Speed Development

Today's podcast features Andrew Sheaff. Andrew is a swim coach, most recently working at the University of Virginia where the Cavaliers won multiple NCAA team championships.  He is also the author of ‘A Constraints-Led Approach to Swim Coaching’, a book that examines how to build skills organically during the training process.  He is currently consulting with clubs and coaches to help them improve their skill development strategies. On the last show Andrew spoke on empowering the technical development of the athlete, free from overcoaching, as well as how to create lasting change in technique and performance. On today’s episode, Andrew talks about timing and central motion factors in athletic movement, optimizing constraints for individual athletes, the art of scaling constraints up and down, aspects of over-speed and under-speed methods and much more.

So, like, you can have them go at really high rates, really low rates. You can alternate back and forth.” – Andrew Sheaff (00:22:00) Helping them perceive that rhythm is really important, and then they just need a general sense of it. And then it's like, then you can start challenging it and pushing it, and then they start to figure out how to do it in various contexts under pressure. And that's ultimately what's going to help them race successfully. ” – Andrew Sheaff (00:29:00) Because, you know, if I put a pair of fins on, you know, ten different swimmers, there's going to be a general impact of those fins, but there's also going to be a specific impact for each swimmer because the fin and the swimmer interaction, and those interactions are going to be a little bit different. – Andrew Sheaff (00:44:17) "If you're running like 6x200s with the wind at your back, you get the exposure of running a little. Feeling easier, feeling faster, feeling more elastic for that." - Joel Smith (00:49:00) “Another example would be with the paddles. That can help them feel like what it's like to hold water. But then you take the paddles off with some swimmers, and they hate the feeling of it because it feels like they're pulling with toothpicks. And then the other opposite extreme, sometimes you have swimmers use the tennis balls and you open them back up and they feel like their hands are gigantic and it feels awesome to them. But sometimes you open the hands back up and their hands feel gigantic and they feel like they can't control them like the...
