“Putting Evidence Back Into
Running Injury and Performance”

Gait Analysis Series Part 4: Dr. Allison Gruber – Footwear and Footstrike

by | Runchatlive Podcasts: Gait and Shoes

In Part 4 of our four part GAIT ANALYSIS special, guest Dr Allison Gruber, Assistant Professor in the Department of Kinesiology at Indiana University Bloomington. discusses what the research tells us about footwear and footstrike in relation to reducing running injury and increasing running performance.

Dr. Gruber has been at the forefront of running related research for more than a decade, with over 100 publications. Her primary research interests include the mechanisms of running related injuries and determinants of metabolic cost and locomotion.

Other Episodes:

  • Part 1 with Dr. Max Paquette, Associate Professor of the University of Memphis Human Performance
  • Part 2 with Dr JF Esculier, Vice-President & Director of Research & Development at The Running Clinic.
  • Part 3 with Dr. Izzy Moore, Associate Professor in Human Movement & Sports Medicine at Cardiff Metropolitan University.


If you are interested in starting a Gait Analysis service or updating it to be more evidence informed, podcast host Matt Phillips will be giving his course ‘Gait Analysis For Runners: A Modern Approach’ in May 2023:
• Two live ONLINE mornings – Saturday 6th & 13th May
• One IN PERSON full day – Saturday 20th May at The School in Exeter*

*RECORDING will be available for those who cannot attend the IN PERSON day.
