The Physical Performance Show: Professor Stuart Warden (PT, PhD, FACSM, FASBMR) ‘Preventing Bone Stress Injuries in Runners’

 In Podcast (The Physical Performance Show)

Stuart Warden

The Physical Performance Show host Brad Beer shares a conversation with Professor Stuart Warden (PT, PhD, FACSM, FASBMR) ‘Preventing Bone Stress Injuries in Runners’ in this Expert Edition.

Professor Stuart Warden is an avid runner.  Academically and professionally Dr Stuart Warden serves as a Professor of Physical Therapy and the Associate Dean for Research within the Indiana University School of Health & Human Sciences. Professor Warden embarked on a Post Doctorate at the Australian Institute of Sport and Indiana University Department of Orthopaedic Surgery, following graduation from the University of Melbourne with a Physiotherapy degree in 2001.

Professor Warden’s research interests focus on the form and function of the musculoskeletal system, in-particular the lifelong contribution of physical activity to skeletal health. Professor Stu has contributed to over 170 peer reviewed publications and currently serves as an Associate Editor for The Journal of Orthopaedic & Sports Physical Therapy and also as an Editorial Board Member for Bone, Journal of Bone and Mineral Research and the Journal of Science and Medicine in Sport.

Professor Stuart Warden alongside colleagues Brent Edwards and Dr Rich Willy released a landmark commentary by way of a scientific paper titled “Preventing Bone Stress Injuries in Runners with Optimal Workload”.

In this episode we dive deep into the contents of the recently published paper:

  • What the author’s mean by optimal bone workload
  • Optimal workload to induce skeletal adaptation
  • The fact that not all athletes have good skeletons
  • Why it is that distance running does not build good bones
  • How we can use periodisation to help build more bone
  • The effects of early specialisation with sport and the contribution this may have on bone stress injury risk
  • Why it is that optimising bone structure is critical and how it only develops before puberty
  • How we can positively increase the robustness of our skeleton through bone centric exercises
  • How we can try and minimise training errors to avoid the onset of a bone stress injury
  • And much more

Quotes

“If you can reduce your magnitude in loading just a little bit, you get a much larger decrease of bone stress injury risk.”
“Try to find the balance between intensity and distance.”
“Running itself is not really a great bone building activity.”
“The best time to build bone is before puberty.”
“The thing that loads bone the most is not hitting the ground but muscle contractions.”

“Taking one day off is not going to allow much recovery than having 5 consecutive days for recovery.”
“People who play ball sports before they enter military training have a much lower risk of bone stress injury than those who never played ball sports.”
“Increase your cadence especially if you have multiple stress injury” – Tip on Running Mechanics

Top 3 Tips
– Document your workload
– Look at nutrition, sleep, menstrual cycles and other factors
– Increase your distance before you increase your intensity

“Join and train with a group.” – Top Learning Tip
“You need to do 20 countermovement jumps at least this week.” – Physical Challenge
