Hi @Mudge and @russell,
Thanks for calling out that episode! It was great to get Dr San Millan to talk with Emma-Kate about his personal experience with youth.
I personally find that the Coggans Power Profile does under-estimate athletes, so I’m glad you’re not using that. Especially with Juniors.
This is just my bias, but I don’t personally find power numbers that useful with Juniors. I focus on how they’re performing in the Peloton and the overall development of their aerobic base fitness. A lot of Juniors haven’t gone through their second growth spurt where they put on a lot of muscle mass. So, often their power simply isn’t that good. But, when they go through that secondary growth, power goes up a lot.
For Friel’s Craft of Coaching, I was asked to go through the recent research on Juniors and write a summary (https://www.fasttalklabs.com/the-craft-of-coaching/what-the-research-says-about-junior-development/.) One of the things I saw in several studies was that power numbers in Juniors really didn’t predict future success.
If you’re interested, here’s the list of studies I went through and my bullet points about each: Recent Research on Junior Athletes - Fast Talk Laboratories
Hope that helps!
