‘Overpronation’ … the quack is strong in this one …

…so is the Dunning-Kruger effect. I have written before on some of the nonsensical stuff that gets written on ‘overpronation’, but most of that is limited to the crankosphere blogosphere, and forums where you can just make stuff up and wish it was true and not provide any citations or evidence to back up the wishful […] Continue reading

Footwear and Flatfeet: Correlation or Causation?

One of the arguments that often get advanced for a barefoot lifestyle is that shoes cause flat feet as they weaken the muscles. Not sure how people make that conclusion as there is no evidence that footwear wearing populations have feet that is any weaker than barefoot wearing populations – you would have thought that if such claims were being made, those making it would have something to back it up. Just stating it and wishing it was true is a logical fallacy Continue reading

The influence of running speed on ankle and knee joint moments

I have long suggested that the number one biomechanical risk factors for an overuse running injury and determinate of running economy is joint moments. That is generally affected by variations in joint axes positions. The loads in the tissues and how hard a muscle has to work is determined by the joint moments. Continue reading

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

…. 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. Continue reading

The effects of shoes and barefoot on postural stability

I have no doubt about the importance of plantar sensory input has on normal gait, balance and postural stability; having spent many years looking at the impacts of diabetes and what the sensory neuropathy does to gait and balance. What I do have doubts about, and will address this in greater detail in a future post, is the role that footwear, especially softer footwear, has on attenuating that sensory input. The rhetoric and propaganda is all around that we need to feel the ground to have those appropriate sensations for normal function and postural stability Continue reading

The importance of joint moments in running injury risk and running economy

Back from a holiday and was planning on getting in back into the routine of posting and was planning on writing something totally different today and then the study below turned up. It was not a study on runners and was not on running (it was on walking), so my title for this post is a bit misleading, but I think the study is informing. The study was about joint moments and their differences between the left and right side. Continue reading

The Influence of Arch Type on Injury in Minimally-Shod Runners

We have known for some time that there are different running injury risk profiles for different foot types, often depending on how you choose to classify them. Now this new study is suggesting that different foot types may have different injury risk profiles between traditional shod running and minimalist shod running: The Influence of Arch Type on Injury in Minimally-Shod Runners Galbreath, K.M.; Harrison, K.D.; and McCrory, J.L. International Journal of Exercise Science: Conference Proceedings: Vol. Continue reading

The concept of ‘core stability’ of the foot

The concept of spinal ‘core stability’ is given a lot of prominence in the media, by coaches and by therapists and is allegedly an important concept for prevention of running injury, low back pain and postural related issues. It has gained widespread acceptance. Continue reading

Rearfoot and Midfoot/Forefoot Impacts in Habitually Shod Runners

When comparing the biomechanics of different foot strike patterns, these reseachers set out to answer the somewhat ambiguous question of whether the biomechanical differences are due to changes in footwear, foot strike, or a combination of the Continue reading
