by Carsten Hoever Introduction This is the second part of a series of blog posts about the RunLAB fullbody running analysis offered by the Swedish running shoe company Salming. The first post, which was published on The Running Swede Blog, was mostly a general description of the RunLAB and the general experience. This post will […]
Based upon research published over the past several years, I’ve come to believe the following about the effects of footwear (or lack thereof) on running form: 1. Barefoot running is different and no shoe perfectly replicates the barefoot condition. Running barefoot, particularly on a hard surface, increases the likelihood that a runner will adapt a […]
Nike Pegasus vs. Nike Free 3.0: Does a Moderately Cushioned Shoe Encourage Barefoot-Like Biomechanics?
Nike has long touted the design of their Free line of running shoes as having been inspired by barefoot running. Indeed, the newest Free shoes have the phrase “Barefoot Ride” written right on the insole (see photo at left). Personally, I’m a fan of the Frees since they suit my preference for light, flexible, moderately […]
So far this week I have written about studies that have looked at foot strike patterns in in minimally shod or barefoot runners. A study of the Tarahumara in Mexico showed that even among individuals who habitually wear minimal footwear, foot strike patterns are variable during running. A study of the Hadza in Tanzania suggested […]
Yesterday I wrote a post about a study that examined foot strike patterns in Tarahumara Native Americans from Mexico. That study found that Tarahumara who habitually wear and run in minimal huarache sandals exhibit a mixture of foot strike types (40% midfoot, 30% forefoot, 30% heel), whereas Tarahumara who habitually wear and run in conventional […]
I’ve written a lot about foot strike variability over the years, but I still see people make claims that heel striking is bad, or that barefoot and minimally shod runners don’t land on their heels. Personally, I view foot strike as one aspect of running form that varies with a range of factors. These factors […]
Another Study on the Efficacy and Potential Benefits of a Retraining Protocol to Increase Running Cadence
A few weeks ago I wrote about a study that looked at the effectiveness of self-directed gait retraining for increased step rate in runners. That study found that runners could indeed make lasting changes to step rate on their own, and increased cadence altered biomechanical variables that might increase risk of injury. These changes included […]
Research has suggested that increasing running cadence (steps/minute) by 5-10% can reduce loading at the knee and hip joints, and this has spurred interest in the use of cadence training in clinical settings. In particular, Heiderscheit et al. (2011) found that increasing cadence reduced peak vertical ground reaction force, peak hip adduction, peak hip flexion, […]
Last night I was reading a post by James Dunne on the benefits of running on varied surfaces. In the post I came across a video by podiatrist Ian Griffiths on the topic of limb stiffness in running. I’ve written about this topic myself, and also wrote a post on how alterations in limb stiffness […]
Does Risk of Injury Increase When Transitioning From a Conventional Running Shoe to a Moderately Cushioned Minimalist Running Shoe?
Back in 2011 I attended the New York City Barefoot Run. I was in town for a meeting organized by Merrell Footwear (they invited a bunch of folks – scientists, writers, journalists, runners – to talk shoe trends), and the Barefoot Run was included on the list of events for the weekend. Rather than participate […]
It’s becoming more and more clear based on existing research (and research coming soon) that foot strike patterns in running are influenced by a wide variety of factors. It’s not simply the case that humans use a single foot strike type under all conditions – factors like footwear, surface hardness, speed, and experience all seem […]
