https://www.jospt.org/doi/10.2519/jospt.2022.11288 - the missing link in running injury research is non-running stress. It seems DashLX is one solution to start acquiring more of what consumers are doing, why, and that has great implications for research but also for brands to better understand their consumers.
Using wearable technology data to explain recreational running injury: A
prospective longitudinal feasibility study. Collaboration with the U Essex (Neal, Bramah, McCarthy-Ryan, Moore, Napier, Paquette, Gruber)

Running consistency affects odds of injury. Collaboration with Brooks and others – consistent runners had lower risk of running related injuries but higher incidence of upper leg RRIs https://www.linkedin.com/in/dr-jeff-moreno-622a6a26/overlay/1717357879556/single-media-viewer/?profileId=ACoAAAV_BPoBwpjewd6C4R4pasNUSCkiOuapwew

The Physiology of Peak Performance with Olympian & PhD Shalaya Kipp
Currently Post Doc Mayo Clinic with Michael Joyner
PhD - University of British Columbia, Masters & Undergrad at CU Boulder. 2012 Olympian in steeplechase. Worked on the 4% study in conjunction with the breaking 2 project. Now works with Mike Joyner who made a famous prediction of when 2 hours would be broken in the marathon (predicts 1:57:48).
Curvilinear relation between speed and metabolics and metabolic cost across range of speeds
Viewpoint on physiology of fast marathon RE should be measured near lactate threshold. 1% incline has limits b/c resistance not linear w/ speed. Treadmill inconsistencies
Respiratory muscles during exercise
Talk about running power mechanical vs. metabolic power and connect how metabolic power only takes into account aerobic
Super spikes – why is it hard to measure their impact on performance. What take aways do you have for selecting spikes.
Sports bra restriction on respiratory muscles
Impact of steroids on athlete performance

Aspects of the shoes he tests:
Insoles – can increase perception of comfort, plantar pressures change
Impact testing to compliment human-based footwear testing
Traction testing – how do you test? Is it indicative of real world where humans move in variable ways. Slipping vs. Sticking

Season 2/Episode 1: What can you do to stay resilient and how can shoes improve performance with Jay Dicharry – Physical Therapist, Oregon State University-Cascades, MOBO, Founder, author of Running Rewired
Kinematics and Kinetics of Gait: From Lab to Clinic – We can measure things very precisely in the laboratory from the forces in 3 dimensions at 2kHz to the kinematics at 200 Hz. How has he translated this to the clinic and working with athletes when you do not have all of these tools? Does he find this scary or challenging to make some of the assumptions to make changes?
Alternative upper configurations – joint publication where we found different footwear uppers can significantly alter the performance (part 1) and the biomechanics (part 2) for athletes doing agility movements. 5 movements (single leg landings, triangle, AP, CMJ, skater). Faster on/off, greater rate of force development during propulsion, more efficient movements. Where could that efficiency come from? How is this related to the efficiency he sees in the clinic in coaching athletes?

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.

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.

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.
