Summary

The theme of this episode: we are all powerful dump trucks! The main training discussion was on a new study looking at how strength work may help (or hurt) mitochondria adaptations. This study had wildly unexpected results, just like we like them! We also talked about our experience with sweat testing and some of the research on hyperhydration. We expect the science of hydration (personalized based on genetics) to be a frontier of performance and health in the future. And the future is tasty.

Plus we had so much joy talking about a whole host of topics! Roadmap: Courtney Dauwalter's plan to race UTMB after setting course records at the Western States 100 and Hardrock 100, Megan's breakthroughs in side-short pee science (Nobel Prize?), our theories for why times for longer distances are progressing more than the 800 meters on the track, a study on morning versus afternoon training, some of our favorite storylines from the Tour de France Femmes, listener questions on dealing with injuries and RED-S concerns, 2 incredible listener corner emails, and hot takes. Fact: chocolate melts in your mouth, thus it is liquid fueling. Peanut butter cups are truly nature's performance fuel!

0:00.0	Woohoo! Welcome to the Summer Call Play podcast. We are so happy to be with you today.
0:04.6	Happy Tuesday!
0:05.6	It's Tuesday!
0:06.6	And I'm staring at the most classic David Roach vantage point on this Tuesday. Can you
0:10.6	guess what it is?
0:11.6	Oh my gosh, I have no idea. All I do know is that I was just having a reflection that
0:16.4	the lights are out on our bathroom and have been for the last three months. So I haven't
0:20.3	looked at myself in the mirror almost ever in three months, so I truly have no idea.
0:24.8	It all looks good.
0:25.8	I'm about to say something exciting, but actually the lights happen out on our bathroom, and to
0:29.2	solve it, I'm not going to go to Home Depot to get lights, because that's not that complicated,
0:32.8	like fuck light bulbs.
0:33.8	I'm going to get a lava lamp on Amazon. I think our bathroom is weird enough as it is.
0:38.5	It's like janky from the A's. It's got a belief sign in there from Ted Lasso. It's got
0:43.0	a picture of you peeing in this beautiful area on our wall, and it needs a lava lamp.
0:47.4	That's one of my favorite things about your bathroom decorations is that you took the
0:51.7	money to buy a 20-inch print of me taking a piss in nature. To put on our wall, granted
0:58.1	no one can see it now because it's pitch black. Thankfully, we'll have that lava lamp
1:01.0	soon.
1:02.0	Okay, so now tell me, what do I look like right now? What is the vantage point?
1:04.6	Well, it was 12.95 to get the print of you peeing in the bathroom, and it's so worth it.
1:09.6	Because every time someone goes in there to pee, they're like, look at David. That's so
