  • 7. 7: Individualized science & equipment with Jesse Frank

    Jesse Frank did his masters & undergrad at CU Boulder with Roger Kram where he did a variety of projects from trying to build a mobile, gravity reducing cart, to studying how various bike seats affect cycling comfort, and was a coauthor on the Nike 4% study. Over the previous 5 years, Jesse worked at Specialized where he had experience in the wind tunnel, studying how different bike fits could impact athlete performance.  Jesse is also a 2:29 marathoner, triathlete, and - fun fact - officiated my wedding. Footwear comfort and injury rates  Carbon plate and 1% running improvement Meta analysis of bike fits and injury rate/comfort  Triangle test:

    Keely – Recent winner of Black Canyon 100k, Freetrail Lead of Performance Coaching Team, plan to be a Medical Doctor, former biomechanics researcher and current nutrition researcher. Kate – PhD movement science at VCU, D1 runner and All American at West Virginia, 2nd NCAA 10K. Grew up playing all sorts of sports, always interested in performance. Published 23 articles or abstracts on the biomechanics of movement. Manger of biomechanics at BOA · Comparison of Frontal and Transverse Plane Kinematics Related to Knee Injury in Novice Versus Experienced Female Runners o · Running readiness scale as an assessment of kinematics related to knee injury female novice runners. o · Energetics of vertical kilometer foot races; Is steeper cheaper? o · Considerations for ultra-endurance activities: part 1- nutrition. 
  • 5. 5: Physiology of Training, racing performance, durability, fatigue, VO2 max, and more with James Spragg

    Welcome James, Spragg. James is a coach at intercept performance consultancy. James is also finishing his PhD univ of capetown in exercise physiology where he studied the mechanisms responsible for deterioration in performance during grand tour cycling stage races. James also coaches a number of sky runners and ski mountaineers. Our conversation will cover a variety of performance topics surrounding coaching and physiology. · Predictors of cycling performance success: Traditional approaches and a novel method to assess performance capacity in U23 road cyclists o · Predicting Trail Running Performance With Laboratory Exercise Tests and Field Based Results o · “The relationship between physiological characteristics and durability in male pro cyclists.’ o · Viewpoint Using VO2 max as a marker of training status o· Plyometrics and running economy o 
  • 4. 4: How shoes are made from brief to box & where biomechanics fits

    Dave Dombrow and Kevin Fallon are co-founders of Speedland and have created some of the most innovative shoes on the market. This company refuses to cut corners and design products with performance first in mind. They also both have a fascinating background working for Nike, Under Armor, and Puma. These guys have both appeared on numerous podcasts and my goal here is to interview them in a slightly different way. I want to understand the nitty-gritty of how they have used (or not used) science to develop footwear previously and now. · Kevin’s article on footwear development o · Video of strobel lasting o · Video of tooling injection midsoles o

  • 2. 2: Supershoe Science with Wouter Hoogkamer

    Intro: Wouter was the lead author on the landmark article behind the Nike 4% shoe. Also has published theoretical reviews of how a sub 2 hour marathon would be possible and tries to understand which aspects of footwear lead to improved performance. He is also a great runner with some incredible range… Wouter ran a 48.69 400 m and 1:52 800 m in 2007 and has run 2:30 in the marathon and a 5:58 50 miler in Massachusetts in 2021 and 2022, respectively. - A comparison of the energetic cost of running in marathon o - Altered running economy directly translates to altered distance-running performance o - Energetics and biomechanics of running footwear with increased longitudinal bending stiffness: A narrative review o - Longitudinal bending stiffness does not affect running economy in Nike Vaporfly shoes o - Applying the cost of generating force hypothesis to uphill running o
  • 1. 1: Intro with DBo: Introducing The Science of Performance Podcast

    Welcome to "The Science of Performance," hosted by the trailblazing Dan Feeney, BOA Sr. Director of Partner Product Design and Innovation and supported by the Freetrail Network, this captivating podcast takes you on a journey into peak performance in trail running. This venture traces back to a live podcast session where Dan teamed up with Professional Ultra Trail Runner, Dylan Bowman, to dissect his renowned signature trail shoe brand, Speedland. Witnessing Dan's gift for unraveling the intricacies of athletic prowess, the idea for this remarkable podcast was born. Join us as we explore the science behind athletic achievement and unlock the secrets to unleashing full potential in peak performance.
