Podcast Episode #77: Steven Machek and Brand New Powerlifting and Myosin Heavy Chain Research

In this episode, Steven Machek shares some brand new research on muscle fiber types and muscle creatine content in powerlifters. He explains the differences between the primary muscle fiber types (Type I, Type IIa, and Type IIx) as well as sharing some interesting stuff on hybrid muscle fibers. He blows my mind with new information about Type IIx and athletic performance, as well as new information about Myosin Heavy Chain Composition similarities and differences between males and females in general as well as in male and female powerlifters, specifically.

 

Steven Machek MS, CSCS*D, is a third-year doctoral student at Baylor University that is passionate about powerlifting. His research interests are powerlifting-centered, but also focus more generally on the intersection of resistance training and sports nutrition.
