Wearing shoes impairs intellectual development

Its Sunday, I not feeling too well and am not up to writing something serious. I needed another loon to ridicule. I was wondering what to write about, then I remembered this from many years ago that gave us a good laugh at the time: Among the untold problems that wearing shoes can impose in […]

See what you want to believe in

There is quite a body of work in the psychology literature on optical and perceptual illusions and how they are influenced by seeing what you want to see. I certainly know very little about the psychology and science of this (though I have fun looking at some). I do know enough to know there is […]

Core Muscle Activation and Knee Loads

The ‘core’ is well outside my area of expertise, but I still follow the various cults that think it can cure everything as well as those who think its way overrated. I periodically go back and read this as it appears to me to address all the issues and also this blog post from Cor-Kinetic […]

The Re-emergence of the Minimal Running Shoe

This just turned up in my alerts “The Re-emergence of the Minimal Running Shoe” …. hmmmm, I was puzzled. I thought the opposite was happening and maybe I had missed a swing back the other way. For example a few months ago, Lower Extremity Review covered it this way: The rise and fall of minimalist […]

“Barefoot Running and Hip Kinematics: Good News for the Knee?”; what about “Bad News for the Ankle”?

I have previously had a dig at the nature of the titles of a number of scientific papers, for example, this paper I previously reviewed was titled: “Forefoot strikers exhibit lower running-induced knee loading than rearfoot strikers“; when it could have just as easy been titled “Forefoot strikers exhibit higher Achilles tendon loading than rearfoot strikers“ […]

The Truth about …..

How often have you seen posts in running forums or in the running crankosphere blogosphere, that are headlined with something like “The Truth about….. “. Every time time I read one of those, more often than not it easily debunked pseudoscientific nonsense that people are actually gullible enough to believe. I only raise this as in […]

Patellofemoral Joint Stress during Running with Alterations in Foot Strike Pattern

Déjà vu? Been there, done that? Different Running Techniques Load Different Tissues Differently. Its 6 of one and half a dozen of the other. Etc We aleady know that increasing the cadence reduces knee loads; and leaning forward at the hip decreases knee loads but increases hip loads whereas leaning forward at the ankles also decreases […]

Genetics and Running Economy

The cause of an overuse injury in running is that the cumulative load on the tissues is beyond what the current state of the tissues can tolerate, so it breaks. Historically the focus has always been on the cumulative load and its only been more recently that the focus has been on the state of […]

Muscle strength in shod, minimalist and foot orthotic wearing runners

I going to start off with this image¹: There is plenty of the usual propaganda and rhetoric about foot orthotics weakening muscles in the crankosphere blogosphere, therefore they are evil: Truth or lie? I already addressed the issue of running shoes weakening muscles (they don’t); but that has not stopped the fan boys still claiming that they […]

The effect of forefoot varus on the hip and knee and the effect of the hip and knee on forefoot supinatus …

…. say what? This study, that I will get to eventually, gives me the opportunity to address an issue I have been wanting to get to for a while, so the appearance of the research was timely. The issues surrounding forefoot varus and forefoot supinatus, even just not only on the terminology, but the diagnosis […]

Clustering of foot strike patterns when running

While it is well known that the foot strike pattern does vary with velocity, it is not the sole determinant of the foot strike pattern as many elite runners heel strike when running fast and a runner’s self determination of their foot strike pattern appears to be poor. However, the data that quantifies velocity and […]
