The Science of Performance with Dan Feeney

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: Aprospective longitudinal feasibility study. Collaboration with the U Essex (Neal, Bramah, McCarthy-Ryan, Moore, Napier, Paquette, Gruber)https://www.sciencedirect.com/science/article/pii/S1466853X23001578?via%3DihubRunning 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_BPoBwpjewd6C4R4pasNUSCkiOuapwewDoes Midsole Foam Energy Return Influence Fatigue.

The Physiology of Peak Performance with Olympian & PhD Shalaya KippCurrently Post Doc Mayo Clinic with Michael JoynerPhD - 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 speedsViewpoint on physiology of fast marathon RE should be measured near lactate threshold. 1% incline has limits b/c resistance not linear w/ speed. Treadmill inconsistenciesRespiratory muscles during exercise Talk about running power mechanical vs. metabolic power and connect how metabolic power only takes into account aerobicSuper 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

Episode 3: How do your biomechanics affect your performance and injury risk? With Allison Gruber – Associate Professor University of Indiana. PhD UMass Amherst and Masters East Carolina. Has worked deeply on the entire spectrum of running mechanics. from the mechanics and energetics of footfall patterns in running Impact causes injury hypothesis – Claire Milner impact shock in runningReal world vs. in-lab biomechanics Wearable technology to explain running injury Footstrike patterns and race performance in 2017 world champs 10k Rearfoot vs forefoot economy and cho oxidation  Isolated effects of footwear structure and cushioning on running mechanics in habitual mid/forefoot runners  Shock absorption 

Doctor of Physical Therapy for 10+ yearsAspects of the shoes he tests:Insoles – can increase perception of comfort, plantar pressures changeImpact testing to compliment human-based footwear testingTraction testing – how do you test? Is it indicative of real world where humans move in variable ways. Slipping vs. StickingDo Pro Athletes need custom shoes Heeluxe’s biggest failures P3 Biomechanics

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 RewiredKinematics 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?Running RewiredMoBo BoardJay’s Website

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   https://pubmed.ncbi.nlm.nih.gov/11689747/  Carbon plate and 1% running improvement  https://pubmed.ncbi.nlm.nih.gov/16540846/ Meta analysis of bike fits and injury rate/comfort  https://pubmed.ncbi.nlm.nih.gov/30556469/  Triangle test:   https://academic.oup.com/chemse/article/doi/10.1093/chemse/bjac003/6543876
