All Summaries for Iron Culture

Podcast Logo

Iron Culture was started by Eric Helms and Omar Isuf as a means of exploring the world of physical culture and attempting to distill a unified philosophy of lifting and to help listeners find greater meaning from the iron. The lifting community has become fractured over the last ~70 years and this Podcast will attempt to explore the fundamental threads that unite these different tribes. The Podcast focuses on dispensing practical, useful information to the listener, bouncing from history, to philosophy, to contemporary lifting culture issues, to science. This can range from teaching the audience about lifting, programming, nutrition, supplements/PEDs and the history of lifting culture. The format includes casual conversations between the two hosts on a variety of topics, discussions with a panel of experts and interviews with authoritative figures in the lifting community.

Ep. 238 - Do Steroids Give a Permanent Advantage? (feat Dr. Alex Kolliari-Turner)
It’s the four-year anniversary of the last appearance of then MR. Alex Kolliari-Turner, now DR. Alex Kolliari-Turner, who returns to Iron Culture to share the results of his now-completed Ph.D. research on the long-term performance-enhancing effects of anabolic steroids (if any). A lot has changed in this burgeoning area of research, as it hinges on a theory of muscle physiology: myonuclear domain theory. Our understanding of the mechanisms of “muscle memory” leads to the possibility of anabolic steroid use providing permanent long-term effects…but what if myonuclear domain theory comes under scrutiny? That’s exactly where the science is at the moment. As new mechanisms of muscle memory are being explored and the first human data emerges, the picture becomes more complicated. Join us in this fascinating episode as we explore the intersection of muscle physiology, performance-enhancing drug mechanisms, and anti-doping! 00:00 Introduction to an anabolic episode of Iron Culture and Dr Kolliari-Turner Iron Culture Ep. 29- The Science & History of Steroids (And Drug Testing)  Kolliari-Turner 2023 An observational human study investigating the effect of anabolic androgenic steroid use on the transcriptome of skeletal muscle and whole blood using RNA-Seq  Kolliari-Turner 2021 Analysis of Anti-Doping Rule Violations That Have Impacted Medal Results at the Summer Olympic Games 1968-2012  Kolliari-Turner 2021 Doping practices in international weightlifting: analysis of sanctioned athletes/support personnel from 2008 to 2019 and retesting of samples from the 2008 and 2012 Olympic Games  07:42 Myonuclear permanency  Gundersen 2016 Muscle memory and a new cellular model for muscle atrophy and hypertrophy  Snijders 2020 The concept of skeletal muscle memory: Evidence from animal and human studies Yu 2020 Potential effects of long-term abuse of anabolic androgen steroids on human skeletal muscle  24:42 Myonuclear domain flexibility?

Ep. 237 - What is the Dietary Fat Minimum Intake? (MASScast 7 ft. Dr. Eric Trexler)
The MASScast Iron Culture episodes are back! Today Dr. Eric Trexler joins us to answer the murky question: “What is an evidence-based guideline for a minimum dietary fat intake?” It’s easy to find guidelines and minimums for various circumstances and goals for protein, and while there is some debate, the same could be said for carbohydrate. However, a minimum intake for fat has been elusive. Fortunately, Dr. Trexler has been thinking deeply about this topic and wrote an extensive article on the topic in our upcoming issue of The MASS Research Review, and he’s here to discuss his conclusions in depth with the CULT. Make sure to tune in, as this information can inform best practices in various situations, as the answer isn’t a simple black and white one.
