Ep. 157: Collagen supplementation/Greer Van Dyck of SBTGRVL
In this episode:I supplementing with collagen a way to perform better, recover faster and manage injury? On the Medical Mailbag we look at hat evidence there is on the subject in order to tease fact from marketing fiction. Plus, a conversation with the community relations director of the SBTGRVL. The conversation highlights the delicate balance between tourism and local agricultural interests, emphasizing the friction that has arisen as the event has grown in popularity. Initially conceived in 2019, SBT Gravel has transformed from a local gathering into a significant attraction, drawing thousands of cyclists from across the country. However, this growth has not come without challenges. Local ranchers and residents have voiced their concerns about the impact of the event on their livelihood and the integrity of the community. The hosts delve into the specific changes implemented after the feedback received from the community following the 2023 race, including the reduction of pre-race shakeout rides and an increased effort in communication with local stakeholders. As the organizers navigate these tensions, they reflect on the importance of finding common ground and fostering a collaborative environment for both cyclists and the local community.Segments:[09:47]- Medical Mailbag: Collagen supplements[t39:53]- Interview: Greer Van DyckLinksGreer's Website

Ep. 156: Fueling for Success: Balancing Body Composition and Performance in Endurance Sports/Maia Watson
In this episode:A rich dialogue unfurls in the Tri Doc podcast, where Jeff Sankoff and Juliet Hochman and Alex Larson tackle the intricate relationship between body composition, nutrition, and athletic performance. The episode serves as a platform to discuss how athletes can navigate the often treacherous waters of body image and performance expectations. Drawing from personal anecdotes and professional insights, Alex highlights the significant risks associated with under-fueling and the surprising lack of risks tied to over-fueling. This revelation is vital for athletes who may succumb to pressures for an 'ideal' physique, often leading to detrimental health outcomes such as RED-S, which can severely impact performance and well-being. Plus, a conversation with top age grouper and soon to be professional Maia Watson. She shares what it has been like to undertake her journey to the upper echelons of our sport in a short time.Segments:[09:22]- Medical Mailbag: Body Composition and performance[46:49- Interview: Maia Watson Linksalexlarsonnutrition.comTriDoc Coaching YouTube ChannelAlex Larson's upcoming podcast@maia.watson on Instagram Links referenced in this episode:www.tridocpodcast.comtridocoaching.comlifesportcoaching.comwww.reverbnation.compatreon.com/tridocpodcast

Ep. 155: Positive thinking and how it impacts performance/Michelle Bond; Unlocking the Power of Fascia: Why It's Essential for Athletes
In this episode:At the commencement speech for Dartmouth College's graduates in June of this year, Roger Federer spoke eloquently on the power of positive thinking and how it enabled him to win close to 80% of his matches over the course of his career despite having lost almost half of the points that he played in those matches. Can athletes in other sports learn from his example and is there evidence to support this notion that being positive can affect outcomes? We discuss in the Medical Mailbag. Also, a conversation with Michelle Bond, a kinesiologist and researcher on the importance of understanding the fascia and how as athletes we can leverage that understanding to improve our performance and recovery.Segments:[08:36]- Medical Mailbag:[38:00]- Interview: Michele Bond LinksRoger Federer's commencement speechMichele's Facebook page @michele__bond on Instagram Michele's Website Michele on YouTube

Ep 154: Which salt is best?/Fiona Moriarty
In this episode:Everyone knows that sodium is an important component of sport nutrition but what form should it come in? For a long time sodium chloride was preferred but more recently sodium citrate is much more popular. Is there a reason for this change and is there evidence that one is better than the other? The Medical Mailbag discusses the evidence. Plus, Irish professional triathlete Fiona Moriarty comes from a running background but has distinguished herself as a cyclist. Hear how she made the transition to multisport and how she is making it all come together with a full-time job.Segments:[07:20]- Medical Mailbag: Which salt is best?[33:10]- Interview: Fiona Moriarty LinksEpisode 10: Exercise induced hyponatremia@fionamoriartytri on Instagram Fiona's Website Fiona on YouTube

Ep 153: Doping in triathlon, the 10% question
In this episode:A widely read and much discussed media article out of Germany quoted researchers who surveyed athletes at the 2024 Challenge Roth on the use of performance enhancing drugs among age group triathletes. The results were somewhat disheartening. Around 10% admitted to using agents that would enhance performance and almost none had any qualms about it. What are these agents? What are the risks of using them? Should we care? The entire episode will be dedicated to try to answer these questions with the help of guests Jim Vance and Matt sharpe.

Ep 152: Muscle typology and training variation/Kennon Heard, cardiac arrest survivor
In this episode:Skeletal muscles are made up of fast twitch and slow twitch fibers each of which has differing properties. The amount of each fiber in muscle varies from person to person and while it is possible to determine this makeup, it is not so easy. The architecture of muscle in each individual is important in determining how a person can perform in different types of sports and also, how each will respond to training. Should people try to determine what their muscle typology is and adapt their training to it? We discuss in the Medical Mailbag. Kennon Heard is an emergency physician and endurance athlete who collapsed in cardiac arrest after a family fun run in May. He discusses his experience and how he is moving forward as well as how the rest of us should think about this experience in context of our own endurance pursuits as we age.Segments:[10:30]- Medical Mailbag: Muscle typology and training[35:14]- Interview: Kennon HeardLinksLearn CPR
