#669 - Ingmar Jungnickel: AiRO.app
Ingmar Jungnickel, an expert aerodynamicist, earned this distinction for his work with US Speedskating, where he developed a revolutionary team pursuit technique known as the ‘American Push’. This strategy used advanced simulation and computer modeling to help the team break world records. His career includes: Specialized Bicycles: He led the aerodynamics department, overseeing the development of high-performance bikes like the S-Works Tarmac and Venge. US Speedskating: He serves as the Chair of the Sports Science Commission and is the 2018 US Olympic Committee Sports Science Coach of the Year. Innovation: He is the founder of AiRO, an AI-powered platform that uses computational fluid dynamics (CFD) to provide aerodynamic bike fitting without a wind tunnel. Aerodynamics plays a significant role in cycling performance, often more so than the weight of the bike. Ingmar emphasizes that many athletes mistakenly believe that a lighter bike is the key to speed. However, the real challenge lies in minimizing aerodynamic drag. By focusing on reducing drag, cyclists can improve their efficiency and speed without the need to invest heavily in new equipment. This insight is crucial for all cyclists, particularly those who may not have access to high-end gear or professional training. One of the most exciting developments at AiRO is the introduction of the Digital Airo Twin technology. Ingmar explains that this innovative approach allows for the creation of a 3D model of an athlete based on just a few photos. This model can then be adjusted for various parameters like limb length and body fat percentage, enabling customized aerodynamic assessments. This technology democratizes access to aerodynamic testing, making it feasible for everyday athletes to optimize their performance without the high costs associated with traditional wind tunnel testing. 0:00:03 - Introduction and welcome 0:01:04 - Journey into aerodynamics 0:03:11 - Development of aerodynamic testing technologies. 0:10:58 - Digital twin technology and its applications 0:16:22 – How AiRO is used by athletes and Fitters 0:28:49 - Upcoming developments and industry impact 0:42:57 – Final thoughts LINKS: AiRO at

The Loan Market Oceanside Mount Half use Race Ranger this weekend. Pro Tri News have put out a survey to collect feedback on the drafting zone rules – we discuss what we know so far. We chat to Dr Warren Bradley, Founder & CSO of Hytro - designers of the first Blood Flow Restriction (BFR) wearable, designed to improve sports performance. Blood Flow Restriction works by tightening a strap around the top of your arms or legs to lock blood in the muscles while you perform light exercise or recovery routines. This helps your muscles get stronger and recover faster than they would without it. When you're strapped in, the muscles that are being restricted fill up with oxygen-poor blood. This makes easy exercises and recovery routines feel tougher. It makes your muscles work harder and so helps your body adapt faster and better, making you stronger, improving your endurance, and helping you recover quicker. Hytro has revolutionised BFR technology to seamlessly fit into performance protocols. Hytro’s patented technology not only complements existing methods for enhancing sports performance but is the gold standard in isolated BFR wearable technology.

#642 - Kelly O'Mara: Feisty Media
This week on FITTER Radio we welcome Kelly O'Mara Head of Content and Sports Reporter for Feisty Media. The new IRONMAN Kona qualification algorithm is significantly affecting female athletes. While early projections suggested a 30-40% representation of women at the World Championships, initial data from races shows this is not the case. In the 'performance pool' an overwhelming majority have gone to men (around 95%), with only about 5% going to women in the initial races analyzed. In some events, like IRONMAN California, only one performance slot was awarded to a woman. In this conversation, Kelly shares her history in triathlon and sports journalism, highlighting the evolution of women's sports and the challenges faced in media representation. She shares insights from the recent Kona race, the impact of the new qualification system on female participation and the implications of IRONMAN’s business model. We review the racing from the Noosa Triathlon at the weekend plus Braden Currie announces his retirement.
