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!

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
1:31:46 Practical takeaways for coaches
