  • Ep. 183: Glucosamine and Triathlon at 80: The Unbelievable Journey of Natalie Grabow
    In this episode:In this episode, we are tackling the very real question of glucosamine supplements and their supposed benefits for athletes. As we navigate through the medical mailbag segment, we dive deep into the research surrounding glucosamine, looking at whether it has any real impact on cartilage repair and overall joint health for those of us who put our bodies through the ringer on race day. We explore the mixed evidence surrounding glucosamine, discussing how it’s often touted as a miracle worker in the world of sports medicine. We dissect the studies that claim benefits, while also highlighting the lack of compelling evidence that definitively shows glucosamine can help endurance athletes recover from injuries or improve performance. Natalie Grebo's journey through the triathlon world is like a fairy tale, but with more sweat and less magic. At the ripe age of 81, she's not just participating; she's breaking barriers, becoming the first female finisher in her age group at the Ironman World Championships. In this episode, we dive into her remarkable story, where overcoming injuries, defying age stereotypes, and embracing the thrill of competition take center stage. The conversation kicks off with Natalie reflecting on her 21 years in triathlon, emphasizing her love for movement and the joy of pushing herself. Despite facing setbacks, her determination shines through as she shares how she navigates challenges and maintains her competitive spirit. With a delightful mix of humor and humility, she recounts her experiences, making it clear that age is merely a number when it comes to pursuing passion and fitness. As the episode unfolds, we also tackle the importance of community and support in the sport. Natalie’s interactions with fellow athletes and her family add a heartwarming touch, showcasing the camaraderie that fuels her journey. So grab your headphones and get ready to be inspired by a true trailblazer in the triathlon world. This episode isn’t just about racing; it’s about the mindset that keeps us moving through life, regardless of age. Natalie’s story serves as a reminder that it’s never too late to start something new, and that the desire to keep going can lead to extraordinary achievements. Tune in as we celebrate not just her accolades, but the spirit of resilience that embodies the essence of triathlon. Whether you’re an athlete or just someone looking for motivation, Natalie’s infectious enthusiasm will leave you wanting to lace up your shoes and hit the pavement yourself!Segments:[08:44]- Medical Mailbag:[37:44]- Interview:Links

  • Ep.182: Tymewear for ventilatory metrics in training and another visit with Matthew Marquardt
    In this episode:In the Medical Mailbag we look at the evidence behind using ventilatory metrics to assess and prescribe training zones as well as training loads especially as it pertains to measurement with the new to market Tymewear chest strap. This tech got a lot of buzz at this year's Tour de France but is it ready for adoption by age groupers? Plus, we catchup with the whirlwind journey of Matthew Marquardt, a med student who’s also a triathlon sensation. With a season filled with victories, including a dazzling performance at the World Championships, Matthew shares the gritty reality behind the glamour of triathlon fame. From the grueling training schedules to the unexpected cramping that could rival any medical mystery, he takes us behind the scenes of his life as he balances studies and races. The conversation turns to the dramatic events at Kona, where high stakes and even higher temperatures led to heartbreaking moments for some of the sport’s best women. Matthew reflects on the emotional rollercoaster that these athletes endured and what it truly means to compete at such a high level under extreme conditions. The dynamic between the race’s history in Kona versus Nice is also a hot topic, highlighting the different styles of racing that favor various types of athletes. With a sharp tongue and an eye for the absurd, this episode humorously critiques the current state of the sport while also celebrating the triumphs of those brave enough to compete. It’s a heartfelt testament to resilience, determination, and the unexpected twists that come with chasing greatness in triathlon.Segments:[10:11]- Medical Mailbag: Tymewear[37:14]- Interview: Matthew Marquardt Links@matthewmarquardt on Instagram

  • Ep. 181: Sipping Tea and Debunking Myths: L-Theanine and the Mercola Tapes
    In this episode:L-theanine is found in tea leaves and promises to help you be calm and focused. Does it work and is there evidence it can help you perform better? We look in to it on the Medical Mailbag. Then, we're diving headfirst into the wild world of wellness disinformation in this episode, where we tackle the absurdity of trusting health influencers like Dr. Joseph Mercola, who somehow manages to make a fortune peddling questionable advice. Our guest, Jonathan Jarry, a science communicator from McGill University, spills the tea (pun totally intended) on Mercola's bizarre reliance on a psychic medium for guidance on health matters. You heard that right—this guy's taking medical advice from someone channeling a spirit named Balon. We chat about how this all ties into the larger trend of seeking simple answers to complex health questions, and why people are so easily duped by flashy claims. As we dissect the ludicrousness of it all, we’ll arm you with some tools to cut through the nonsense and hopefully make better choices in your health journey. So buckle up, because this rollercoaster of ridiculousness is about to get real!Segments:[06:49]- Medical Mailbag: L-theanine[28:57]- Interview: Jonathan Jarry LinksJonathan's Website The Mercola Tapes on YouTube

  • Ep. 180: Lumos sleep mask and From Hockey to Triathlon: The Unlikely Journey of a Future Doctor
    In this episode:Diving into the chaotic yet exhilarating world of triathlon and medicine, this episode showcases the fascinating journey of Pavlos Antoniedes, a medical student who somehow juggles both rigorous academic studies and being a national-level triathlete. Imagine the life of someone who, while mastering the complex anatomy of the human body, also trains like a beast, preparing for grueling competitions. The conversation starts with the absurdity of trying to balance a medical career with the demands of elite triathlon training. Pavlos shares his backstory—how he transitioned from hockey to triathlon, driven by family ties and a desire to find a sport that resonated with him. As we laugh and shake our heads at the sheer madness of it all, he reveals how he manages to keep his training schedule flexible enough to dodge the pitfalls of burnout and exhaustion, all while excelling in medical school. It's a wild ride filled with insights into the pressures athletes face, the mental gymnastics needed to excel in both fields, and the occasional sarcastic quip about medical exams and race days that will leave you chuckling at the absurdity of it all.Segments:[07:28]- Medical Mailbag: Lumos Sleep Mask[time stamp]- Interview: Pavlos Antoniades Links@pavanton31 on Instagram Pavlos 's Facebook page Lumos

  • Ep. 179: Arnica and Stephanie VanBebber on Marathons and Cancer: Should You Be Worried?
    In this episode:In the MMB we take a look at the science behind the popular homeopathic remedy arnica. Is there any merit to this topically applied plant derivative for treating delayed onset muscle soreness? Plus, our guest, Stephanie Van Bebber, brings her expertise in clinical research to the table as we navigate through the headlines that have left many in the running community feeling a bit queasy (and not just from the gels). The study in question reveals that ultra runners might be at an increased risk for advanced adenomas, those pesky precursors to cancer. But before you toss those running shoes into the nearest donation bin, let’s unpack what this really means. It’s not about condemning the sport we love, but rather about understanding the potential risks and the importance of screening. If you’re an ultra runner or just a casual jogger, this episode offers valuable insights into how we can better care for our bodies while still pursuing our passion for running. From the biological theories behind inflammation and gut health to practical advice on when to see a doctor, we cover it all.
