Ep. 269 - Are Social Media PhDs Ruining Fitness? (feat Dr. Milo Wolf, Max Coleman & Dr. Pak) Apr 08, 2024

Show notes

Whitney Houston said it best: "I believe the children are our future, teach them well and let them lead the way." Here at Iron Culture, we're old, irrelevant and out of touch. But, we believe in platforming the next generation of educators to carry on the torch (or at least pandering so they'll platform us in return when we can no longer pay the bills). In this Roundtable we're joined by Dr. Milo Wolf, Dr. Pak, and first-time guest Max Coleman, to discuss the challenges of growing a following using social media in 2024 as an evidence-based content creator. The game has changed what worked for us, won't be as successful, and striking the right balance is not easy, and getting it wrong comes with lashback. Are we all just doing more harm than good? Join us as we discuss!

Ep. 268 - Science Communication, Gatekeeping & The Fitness Industry (feat Dr. Pak) Apr 01, 2024

Show notes

Dr. Pak is back on Iron Culture for his third appearance! This time, he sat down with Omar and Dr. Helms for a meta-discussion on the challenges of science communication. How do you maintain credibility when you're using social media as a science communication tool? This challenge has changed, but it isn't new by any means. The "Sagan effect" describes the well-researched phenomenon by which the scientific community perceives other scientists who get more media exposure as less legitimate scientists - despite the fact that, on average, scientists more active in science communication typically publish slightly more often and with a higher impact than scientists less active in science communication. In modern times, however, the incentive structures are different, and many instances of expert creep, "selling out" and pseudoscience have been propagated on social media by some academics or members of the medical community. In this episode we discuss the challenges of attempting to communicate science without being criticized for doing so, how this has and hasn't changed over time, and the instances of gatekeeping which are ultimately counterproductive to increasing scientific literacy.

Ep. 267 - Addressing Data Fraud in Nutrition Science Mar 25, 2024

Show notes

The holy trinity is back and holy smokes do we have a Holy Ghost of an episode! First, to kick things off the crew discusses the recent "March madness" of powerlifting that just finished: IPF European Champs, the UK Arnold, and Powerlifting America Nationals. Some absolutely stunning performances occurred all over the world in powerlifting and it seems the rising tide of talent has no end. Then we get into the meat - or should I say the bottomless soup - of the episode. While fraud in research is exceedingly rare, it does happen, and unfortunately, more common issues such as p-hacking are a far more prevalent issue. What is to be done in situations like this? One tool, as the Erics discuss, is replication.

Ep. 266 - Are Plant-based Proteins Actually Superior? Mar 18, 2024

Show notes

After their recent reconciliation, the Erics got together for this duo episode to bond over their mutual love of protein. But, dear listener, this might not be the home-cooked high-protein meal you hoped for. Dr. Trexler tackles the question of whether or not, GASP, protein restriction might extend lifespan! Then, to add insult to injury, the Erics dig into the question of whether or not plant-based protein sources could be superior to animal sources for improving healthy aging! Along the way, you'll also learn about the limitations of both epidemiological and mechanistic protein research, and how the two can complement each other to lead to more robust conclusions. So grab your pea protein shakes - or maybe your protein-free placebo - and tune in for another monster episode of Iron Culture.

Ep. 265 - Are Your Supplements Contaminated? Mar 11, 2024

Show notes

As you know, Iron Culture reps the neutral to positive gang around these parts. While most new supplements released to the market don't pan out as effective, some do. So, if preliminary data supports the potential efficacy of a new supplement, why not try it out? The only potential downside of trying a new supplement is wasted money, right? Not so fast. In this episode the Erics duo explains why the typical supplement consumer is not accurately weighing the true potential cost of supplement investment. Unbelievably, some data indicates 10-30% of all supplements are contaminated - you heard that right. Could that be true? If so, why and how is this happening and what can you do about it?

Ep. 264 - Why the "52 Set Study" Doesn't Matter Mar 04, 2024

Show notes

Evidence-based practice has unfortunately become a meme, and its meaning, role, and utility are less understood than they were just a handful of years ago. In this episode we dive deep, discussing how to incorporate study findings into practice. If you don't have the ability to gauge the impact of a study's findings, how do you stay up to date? We answer critical questions like: How does the hierarchy of evidence operate in a field where many meta-analyses have errors? What is the role of mechanistic research compared to applied research, and when should you look to each to inform what you do in the trenches? At a time when many seem ready to simply throw in the towel on the evidence - despite it actually being of a higher quality, than it ever has been, we are here. We are going to bring you back from the brink so that you can make those sweet, sweet evidence-based gains.

Ep. 263 - Is Protein Timing Debunked? Feb 26, 2024

Show notes

It's time for a MONSTER episode about protein. Naturally, Helms has recused himself because of his heavy biases and conflicts of interest with the shadowy figures behind Big Protein. As a result, Trex and Omar take a trip down memory lane and discuss everything we used to know about protein, and how a surprising percentage of that knowledge has changed over the last decade or so of research.

It wouldn't be fair to say that everything you thought you knew about protein is wrong, but there's no question that evidence-based protein guidelines have been significantly impacted by some paradigm-shifting studies that have occurred in the last few years. In this episode, Trex and Omar discuss what these new studies have taught us about protein, and how we can put this new information into action.

Ep. 262 - Sheffield 2024 Recap Feb 19, 2024

Show notes

The trio is back on the heels of THE Sheffield 2024, the biggest powerlifting competition to date, which outdid its inaugural 2023 performance. Once again, the 12 best IPF-unequipped women and men clashed in a cross-weight class competition ranked by their total as a percentage of their respective world record. This meet incentivizes going BIG, rewarding cash prizes for both placing and breaking individual lift records, with over $500k USD up for grabs, boy did it deliver. The sold out crowd watched the first ever 300kg women's squat in sleeves by Sonita Muluh, and Jesus Olivares break Ray Williams' squat world record. Women's champion Agata Sitko totalled an astonishing 600kg at 69kg, benching an incredible 152kg, annihilating the 69kg total record by 51kg alongside 10 additional women who totalled over the world record. Without question, powerlifting is on the rise, and there is a lot to discuss, so make sure to listen in!

Ep. 261 - A Unified Theory of Metabolic Adaptation? Feb 12, 2024

Show notes

The nerd super duo is back at it again. This time, Dr. Trexler plays Sherlock and Dr. Helms plays Watson in a discussion of how overtraining syndrome, metabolic adaptation, relative energy deficiency in sport, exercise energy compensation, body fat regulation, and more, are both distinct from one another, yet are all also closely related. Surprisingly, it took a couple meat head bodybuilders to notice the shared characteristics and overlap between these separate concepts. That's precisely because bodybuilders are crazy enough to go through a process that often results in their simultaneous occurrence! Listen in to find out what these concepts are, when they intersect as well as diverge, how you can identify which you or your clients are experiencing, and what to do about it.

In classic Iron Culture throwback style, it's just Omar and Dr. Helms on this one, while the leader of Trex-topia is away at a conference. Omar and Eric give you the classic banter you love, go over reviews, and even engage in an off-the-cuff discussion of the health at every size movement. Then, they get to the meat of the conversation, a recent paper published on whether or not a lumbopelvic movement screen can predict back pain in powerlifters. What can this study teach us about the links between pain, injury, and movement in powerlifting? Tune in to find out!
