Fitter Radio Triathlon Podcast

Dr. Amanda Sadler is a Fellowship-trained Sports Medicine Physician and Functional Medicine Certified Professional. Amanda's focus has been on primary care and functional medicine. Functional medicine looks at the root cause of a disease from the cellular level to understand its influence on the whole system.

Her training as a doctor has been shaped in part due to her own athletic career and her own missed diagnoses. She was a two-time Olympic Trials qualifier in 2004 and 2008, a leading competitor on the ITU circuit, and in 2013 she won her first Ironman event in Brazil. Amanda dealt with gastrointestinal issues throughout much of her early career. She knows that her career as a triathlete could have been different had those issues been solved earlier and treated correctly.

In this conversation, Dr. Amanda Stevens-Sadler shares her journey from being a professional triathlete to a physician. She highlights the importance of gut health in athletic performance and the need for a shift towards functional medicine, which focuses on individualized care and optimal health rather than just treating symptoms. Dr. Sadler emphasizes the signs of dysfunction that athletes should not ignore and the differences between conventional and functional medicine in addressing health issues.

We discuss the intricate relationship between gut health, stress and athletic performance - emphasizing the importance of personalized approaches to health, particularly for athletes - and introduce her Champion Athlete Method, which focuses on optimizing performance through understanding individual needs and managing stress effectively.

The race within a race… Guy and Kate gear up for the IRONMAN 70.3 Sunshine Coast this weekend.

We review the racing from the Supertri Pro Series Final in Jersey.

British professional triathlete Joe Skipper has been handed an 18-month competition ban for an Anti-Doping Rule Violation (ADRV) caused by three whereabouts failures within a 12-month window.

Peptides in triathlon - the line between recovery, anti-aging treatments and performance enhancement. We consider how accessible these treatments may become and whether existing testing rules can keep pace.

We chat to Bruna Maia and Fabienne Maia of Augo Training. Augo is an intelligent assistant software platform designed specifically for endurance sports coaches and their athletes. It provides a central platform that streamlines communication, daily task prioritisation, performance data analysis and workout planning acting as an 'intelligence layer' for sports coaching. The platform uses artificial intelligence to remember client preferences, track past injuries and flag exactly which athletes need immediate plan adjustments. Ultimately, they handle the heavy data crunching and paperwork so that human coaches can save time and focus on building the all-important coach/athlete relationship.

This weekend… IRONMAN 70.3 World Champs in Nice, we give our picks for the win.
