Summary

We conquered the WOOHOO yips before this amazing episode! The main science topic was on a new study that examined the causes of injuries in a 5205-athlete sample. The headline finding was relatively intuitive, but the sub-finding was so shocking that we are still picking our jaws up off the floor. We break it down and discuss how it may clarify training theory!

And this one was full of our favorite topics! Other topics: the yips in athletes (and podcasters), Megan’s Aspen Mountain breakthrough, the interaction of high carb and bicarb to make endurance sports faster, the best protein supplement we have tried, one of our heroes Kate Courtney wins the Leadville 100 mountain bike, Kilian’s next project in the USA, Steph Curry doing weight-vest trail running, and the tricky conversation around bodyweight and health happening in women’s cycling. 

Plus there was a Q+A on the mechanics of podcast recording, nutrition considerations for vegan athletes, the complications of rhabdo in ultra athletes, “purposeful flow” in training plans and how that relates to a new study on overload blocks, overcoming fear in racing, daily carb intake, and high carb in the birth process.

It finished with a quote that we’ll be living by. Let’s feel what there is to feel while we are here.

We love you all! HUZZAH!

Woohoo. Welcome to the SomeWork All Play Podcast. We are so happy to with you today. Happy Tuesday. It's Tuesday. And David, we did it on this Tuesday. We did it. We did it. We got past woohoo. How did that happen? Okay. It was all my fault. We're going to append this at the end of the episode because I just, we have a routine where we do a practice woohoo. I don't know why we need to do a practice woohoo. It's an audio thing. Remember the audio used to be awkward? Like the first sound that we made was kind of distorted on audio. So we would always do a practice woohoo and then the real woohoo. But you messed up this time. Yeah, because then it was sweet. I inserted a reference to how beautiful I thought Megan was. And that threw everything all off.

0:35.0

You were like, woohoo, you're beautiful. And I'm like, whoa. Well, first of all, I was like, thanks, man. I appreciate it. And then for some reason, it made me real silly. This is a business trip. This is not a vacation. The woohoo's. And then we did, how many woohooos do you think we did? Like 16. They were like, we got the Yips.

0:36.3

Yeah, it was truly the Yips.

1:12.0

So the Yps is a fascinating psychological principle. We've talked about it a lot on here. In fact, in the Anthropocene reviewed, one of my favorite books ever by John Green, he's a whole chapter on the yps. And essentially it's where the brain anticipates action and overthinks very simple behaviors. Like the classic example is in baseball, a second baseman who just has a very short throw to make, will lose the ability to make that throw.

1:15.6

And maybe the most wild example I've ever heard is a tennis player that lost the ability to

1:21.4

toss the ball up to hit the serve, like maybe the easiest thing they do in their entire career.

1:26.4

They ended up coming back for a top five world ranking eventually. But the Yips is strange and we got a very acute case of it. It is strange. Also, I love that you brought up baseball because that's how I got myself back. I was like, think about something. Yeah, yeah, yeah. And you know what they always say when you're like supposed to think about something to like turn something off? You think about baseball. And I was like, okay, woohoo, baseball, woohoo baseball. And we eventually did it. You think about grandma and baseball. That's what you do. It's what we're doing over here. Yeah, I feel like actually, can you imagine if you're just like up there at the plate? And instead of like the woohoo, you're about to head a home run and you're just like,'re beautiful and it messes everything up well home run's a hard thing to do that's not necessarily something where

2:04.2

the yips happen which is really interesting it's almost always the most simple actions like putting for

2:09.4

golfers and in baseball a wild example was a catcher lost the ability to throw the ball back to the pitcher

2:15.9

which isn't even in the game of play that's something that happens just to keep the game going. And yeah, that was our woohoo situation. So, hey, anyone out there that ever suffers from this, talk to us, talk about it. I think that's the big advice with all of it is you figure out a way through it by being open about it and not being scared of it. And that's what we did. And that's why this podcast is getting started. And then I was wondering, I was like, what happened to us? Was it something? We were feeling silly during this like woohoo event. Did something happen to like R.T? Well, I'm not feeling silly anymore. You're not feeling silly anymore. You're like business? I'm serious. This is the most serious episode you've ever heard, which brings us to the roadmap. We're going to start by talking about Megan's breakthrough, then two products we love,

2:35.1

a study on what causes injuries, fascinating findings there that we need to go back and forth on. News, including Killian's next project, which is in the United States, and Steph Curry on trails. Plus more news. We actually went through a news battle a few minutes ago. We're like, what can we keep in here? And I wanted to keep a lot in there. That's some good news. Yeah, you kept it all inserted. It was a little much, but we'll see. Plus, a Q&A on the podcast recording. Nutrition for vegan athletes. The weird and uncertain diagnosis of rabdomyalysis, this is really important for every ultra-marathoner out there. Overload training

3:24.6

blocks. We have a study there as well. Fear and racing, daily carbs, birthing carbs, birthing carbs. I like that one. Hmm. Pacing intervals, heart rate anomalies, and more. Okay, we better get to birthing carbs. That's the most important thing. I included that because once I got the birthing carbs question, I said, I don't know.

3:22.7

And you might know a little more than I do.

3:24.6

We've actually gotten the question. thing. I included that because once I got the birthing carbs question, I said, I don't know.

3:42.0

And you might know a little more than I do. We've actually gotten the question multiple times.

3:45.6

This is not the first birthing carbs question. So I was like, the people need to know.

3:48.7

Everyone wants to go high carb and labor, apparently. Okay. So the first thing, really the only thing on

3:54.6

our lives is Megan's transcendent performance last week. So you did

3:58.9

the Aspen Heavy Half Trail Marathon on Saturday. And later in the week, just kind of on a whim,

4:05.1

you went up Aspen Mountain, which is this iconic climb that you've done before hard at your peak

4:10.3

in 2017, before your heart issues and your hamstring surgery and all of that. And you had really low expectations coming in. Well, I've done it a number of times dating back to 2017 when I kind of felt my fastest self. Like I feel like in 2017, I had a great racing year. I felt really strong. And it's always been this like kind of intimidating time on paper is to have, you know, where I am now postpartum after two kids and some of the health

4:31.5

issues and comparing that to 2017. And it was nice. I was in a mindset like, so this was
