I currently sitting in Toronto airport waiting for a flight, so will not say anything much on this: The effects of barefoot and barefoot inspired footwear on tibiofemoral kinetics during running Jonathan Sinclair Human Movement. ISSN (Online) 1899-1955, DOI: 10.1515/humo-2016-0022, October 2016 Purpose. The current investigation aimed to examine the effects of running barefoot and […]

Impact Related Factors and Running Injury
I have blogged before (Just How Significant are Heel Impacts at Causing Injury When Running?) and repeatedly commented that the evidence that links impact related factors to running injuries is far from compelling. I am not saying they don’t, it is just that the evidence supporting the link is not strong (and one study has […]
Effects of a seven week transition to minimalist footwear
One of the criticisms of some studies comparing the mechanics of minimalist vs traditionally shod footwear is that the intervention is acute and the effects were not measured after a period of appropriate acclimation to the different conditions. The results may or may not be the same after that acclimation or transition – we simply […]
Timing of ‘heel off’ in different running shoes
In the context of some of the issues that I wrote about yesterday concerning the problems with the “pronation” paradigm as the basis for prescribing running shoes, a number of years ago we decided to do a study looking at how a different parameter might be affected by the so-called ‘motion control design’ features of […]
Review of Lieberman et al’s (2010) paper in Nature on Barefoot Running
Since starting this blog I have tried to cover every relevant piece of research when its published as well as summarize some topics in the context of what the evidence is saying. I have missed a few and still do have a bit of a backlog of recent ones. It all comes down to allocating […]
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 two: Rearfoot and Midfoot/Forefoot Impacts in Habitually Shod Runners Boyer, Elizabeth R.; Rooney, Brandon D.; Derrick, Timothy R. Medicine […]
Barefoot vs shod running: Effects on tibia loads
One of the key reasons often suggested for transisitioning to a barefoot running technique is to reduce the impacts loads, which is only an important issue if you actually believe there is even a problem with impact loads and running. I previously reported a study that showed that tibial strain was actually greater when barefoot […]
What happens during the swing phase that is related to impact loads?
The biomechanics of peak impact loads and loading rates continue to be researched on the assumption that they are related to an increased risk for injury. I keep harping on about the evidence for that is hardly compelling and there is plenty of evidence that it is not a risk factor for injury and some […]
Decreasing vertical impact loads via increasing ankle loads in Chi Runners
Hot on the heels of the systematic review last week that confirmed the adage that you can’t decrease the load in one tissue without increasing it in another and that different running techniques load different tissues differently, we have another study: A Comparison of Negative Joint Work and Vertical Ground Reaction Force Loading Rates between […]
Just How Significant are Heel Impacts at Causing Injury When Running?
I have always really struggled to understand why there is so much fuss about reducing impact forces to treat and prevent overuse injuries in runners. Everywhere you go in the crankosphere blogosphere heel impacts are the cause of all evil and have to be eliminated at all costs. Even in the scientific literature, for example, […]
Increased Lower Limb Loading with use of Minimalist Running Shoes
Impact loads are widely believed to be associated with some injuries in runners, though the evidence for that is not overly compelling, but it does make sense that reducing impacts may help prevent overuse injuries in runners. A number of different strategies can be used for this and one that is commonly advocated is the […]
Running Asymmetry, Loading Rate and Injury Risk
Asymmetry in the gait is common and is assumed to not necessarily be a good thing for a unidirectional activity such as running, especially if the asymmetry is in impact loads. Various intervention strategies are often used to make the gait more symmetrical, if the asymmetry is assumed to contribute to any injury or gait inefficiency that is present. […]
Tibial strain and barefoot running
Tibial strain and impacts have been getting a lot of attention lately due to all the comments about heel striking being the cause of most running injuries (its not) and this is an important reason why there should be a midfoot or forefoot strike when running. Transitioning away from a heel strike does reduce that […]
Impact Reduction Through Changing to Midfoot Strike Pattern vs Low Drop Footwear
There has been considerable interest recently in altering running technique to reduce impact loads and loading rates in the belief that this might reduce injury rates. There was a recent study I previously wrote about and now there is this one: Impact reduction through long-term intervention in recreational runners: midfoot strike pattern versus low-drop/low-heel height […]
Impact Reduction with Chi Running
When new research is published, its always intriguing to watch how different communities respond to it and the interpretation or spin that gets put on it¹. I already discussed the The ‘Running Shoes Causing Knee Osteoarthritis’ Debacle in a previous article and how the spinning and re spinning of false headlines lead to a myth. This […]
