Injury Series: Tibial stress fractures and stress reactions: The role of bone structure, impact, and calf strength

Tibial stress fractures are related to medial tibial stress syndrome, which you can read about hereFor an in-depth discussion of return-to-running programs after a stress fracture or stress reaction, see this article This installment of the Injury Series deals with tibial stress fractures, one of the most serious of the common running injuries.  A stress … Read more

Brief Thoughts: A critical examination of “Foot Strike and Injury Rates in Endurance Runners: a retrospective study”

Two very different footstrikes captured on high-speed video This post is a bit behind the times, but I thought I’d get it out there regardless.  This post is a short analysis which takes a look at the latest research from Daniel Lieberman’s lab at Harvard University.  Lieberman is, of course, famous for his paper on … Read more

Injury Series: Uncovering the role of hip strength and mechanics in the cause and treatment of patellofemoral pain syndrome

Today we are tackling the most common running injury of all: patellofemoral pain syndrome, alternatively known as runner’s knee, anterior knee pain, and (sometimes erroneously) chondromalacia or chondromalacia patellae.  As is often the case, there is some controversy about the naming.  “Patellofemoral pain syndrome” or PFPS is the broadest and most common term, but is … Read more

Injury Series: Biomechanical solutions for iliotibial band syndrome

It’s been a while since we’ve thoroughly reviewed an injury, so today we’ll be looking at another one of the “big five” most common running injuries.  We’ve already seen how treatment for Achilles tendonitis has been revolutionized by specific eccentric exercises to remodel damaged tendon collagen; today’s topic is iliotibial band syndrome, sometimes also referred … Read more

Injury Series: Flat eccentric heel drops for insertional Achilles tendonitis

Introduction Back in August, we saw how a rehab program consisting of eccentric heel drops with a bent and straight knee reversed damage to the Achilles tendon by inducing collagen remodeling.  One thing I didn’t make clear enough is that Alfredson’s eccentric heel drop protocol, developed in 1998, was designed for midpoint Achilles tendonitis.  In … Read more

Eccentric decline squats, tendon remodeling, and patellar tendonitis

Note: Patellar tendonitis should not be confused with patellofemoral pain syndrome, or “runner’s knee,” a different injury in the kneecap area with a different ideal treatment protocol Last time, we saw how an injury rehab protocol consisting of eccentric heel drops can remodel collagen in an injured Achilles tendon.    The intervention was impressive for two … Read more

Injury Series: Eccentric exercise and tendon remodeling, part I: Achilles tendonitis

Attention readers: I have published a significantly revised and updated article on midpoint Achilles tendonitis.  I strongly recommend you read that instead! The information below is incomplete and out of date! Click here to go to the updated Achilles tendonitis article. Note: if you are looking for information on insertional Achilles tendonitis, see this article … Read more

The cumulative damage theory of injuries

I’ve had injuries on the brain lately.  Why do they happen? My high school’s training room had a sign outside that said “Running injury? TOO MUCH, TOO FAR, TOO SOON.”  Needless to say, the trainer wasn’t very helpful.  But the medical/scientific consensus isn’t much more helpful than that.  Overuse injuries are “tissue damage that results … Read more
