Fun with statistics: A tutorial on using linear regression to develop race time conversions

As you can see, I’ve been playing around with numbers recently.  “Conversion charts” intended to predict future race performances (or equivalent race times) based on a previous race abound on the internet and in running books.  But they often don’t have the race distance you are looking for.  And the various conversion tools runners use … 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
