312. How Blood Volume Impacts Performance and Adapts Fast, The Scary Potential of Lactate Supplementation, The True GOAT, and The Circle Pit!

5/26/20261 hr 23 min

We basked in some amazing news before this great episode! The main topic was a breakdown of one of the most important elements of performance and health: blood volume. 

Studies show that blood volume can seem to act as a synonym for fitness, with one finding that 6 weeks of training gains can be reversed with a phlebotomy that returns blood volume to baseline levels. Positive adaptations can happen in a few days, and it clearly matters for performance. If any other intervention worked like that, you’d assume everyone would be talking about it all the time. But blood volume is not discussed often! We pull back the curtain on the science.

We also talked about a new review article on exogenous lactate supplementation. It might be a brave new world in the next 5 years, but right now there are more questions than answers. We speculate!

And this one was full of cool topics! Other topics: the shockingly good news Megan has received in recent heart tests, our disdain for the Enhanced Games, recent age group doping news, the Satisfy Circle Pit, the true GOAT of endurance, running v. biking, uphill treadmill workouts, and lots more.

Yes, David actually hit himself for a joke on this episode. Podcasts are definitely the medium for physical and visual comedy.

We love you all! HUZZAH!

  1. Megan Roche· Host0:00

    Woo-hoo.

  2. David Roche· Host0:01

    Welcome to the Somewhere Call Play podcast. We are so happy to be with you today.

  3. Megan Roche· Host0:04

    Happy Tuesday.

  4. David Roche· Host0:04

    It's Tuesday.

  5. Megan Roche· Host0:05

    And I can't stop grinning on this Tuesday.

  6. David Roche· Host0:07

    Oh, my goodness, I know where this grin's coming from.

  7. Megan Roche· Host0:10

    It's lighting up right now. [laughs] I can't stop.

  8. David Roche· Host0:12

    [laughs] Best vibes ever to start a podcast. Um, so if our listeners have been around for a little bit, Megan's been going through heart issues for five years now. It's been such a journey. You've been so courageous through it all, and you've told your story through it all. And two weeks ago, you described your most recent trip to the hospital, your three-day stay- Mm-hmm ... at the amazing Airbnb, Boulder Community Health.

  9. Megan Roche· Host0:33

    Yeah, Boulder Community Hospital really kind of is like an Airbnb.

  10. David Roche· Host0:36

    Yeah.

  11. Megan Roche· Host0:36

    It had catered food. Actually, that goes above and beyond an Airbnb. [laughs] Even had a toothbrush for us, the perfect kind.

  12. David Roche· Host0:42

    [laughs] Yeah. Honestly, when you have two small kids, it's a great getaway.

  13. Megan Roche· Host0:45

    You know, I thought about that for a minute, and then I was the one that was being woken up every three hours- That's true ... for troponin blood draws, and I was like, "Get me out of here."

  14. David Roche· Host0:52

    It was pretty nice for me, [laughs] is what I'm saying.

  15. Megan Roche· Host0:53

    At first it was, like, 9:00 at night, and I was reading a book in bed, and I was like, "Gee- Yeah ... this is peaceful." And then they came in over and over and over again, and I'm like, "You know- Yeah ... uh, not so much."

  16. David Roche· Host1:02

    And when your heart goes to V-tach in the corner- [laughs] ... it's not necessarily a fun thing. Uh, and you're having eight million PVCs and all that. So let's give them an update. You'll... You can take the reins here, Megan.

  17. Megan Roche· Host1:12

    I got good heart news last week. My EKG normalized, which was awesome. I did so many tests, and I feel- Yeah ... like I was waiting for them. They took a long time to come back.

  18. David Roche· Host1:21

    Yeah. It's just so remarkable. So three weeks ago, we were in the hospital, and you know, I was there with you as the doctor said, "You don't just need to retire.
