Dr. Andy Galpin, world leading muscle fiber researcher, is back on Iron Culture! Dr. Galpin is not only a researcher, but a sports scientist and coach working with some of the most prominent elite athletes in the world, and an excellent science communicator. So, it was a privilege to have him on to talk Muscle fiber typing; because everyone talks about it, but very few people get it right when they do. Should you train differently if you’re predominantly a fast or slow twitch lifter? Can slow and fast fibers convert into one another? How do we measure the fiber composition of muscles? Are fast twitch fibers stronger than slow twitch? Can you produce fiber-type specific hypertrophy? Why are exercise science classes still teaching things about muscle fiber types that were shown to be wrong decades ago? What is on the horizon in this area of research? All of these questions are answered in this highly educational episode!
00:00 Welcoming back Dr Andy Galpin to the Iron Culture Joe Rogan experience and the muscle biopsy procedure
10:14 History of the muscle biopsy
14:03 (re)Introducing Dr Andy Galpin

19:14 The different function of muscles and fiber types
30:50 Fiber type profiling and the methodological limitations
39:21 Science communication and the defensible and indefensible reasons for the perpetuation of muscle fiber myths
52:22 The multinucleated cell and limitations of current research methods
1:09:44 The history of fiber typing and new methods

0:02.0 | Omar. |
0:03.2 | Andy Gelp and welcome back to Iron Culture. |
0:06.6 | The Iron Culture, Joe Rogan Experience, I want to ask you a question today. |
0:12.4 | Who would win in a fight, you think? |
0:13.9 | A silverback gorilla or a grizzly bear? |
0:17.7 | See, what I'm actually wondering is, did I screw this whole thing out? |
0:20.6 | Because I feel like you guys both clapped and I didn't clap, did I screw this whole thing out? Because I feel like |
0:21.2 | you guys both clapped and I didn't clap. So this whole thing? Did I ruin the whole? No, no, |
0:26.7 | because you're, you're synced up in the mind. You're synchronized. You don't need the clap. You did it |
0:31.8 | spiritually. Yeah, yeah, yeah. That answer your question directly. I don't think either one of them went. |
0:39.0 | I think Eric probably beats it both. |
0:41.0 | Dang. |
0:42.8 | Just as humble as I remember. |
0:45.6 | Andy, here's a personal question for you. |
0:48.0 | So we're going to be talking about, you know, muscle fibers. |
0:50.9 | A question for you, performing a biopsy in order to assess fiber composition. |
0:58.0 | I've heard through the grapevine that you performed it a few times. |
1:03.2 | Out of curiosity, you or your team, how many times have you performed set biopsy? |
1:09.4 | Oh, man. |
1:12.2 | Oh, that numbers. |
1:14.6 | Well, I think we've analyzed over a million single fibers in my lab. |
