Supination Resistance is another one of those topics that I find myself writing about a lot (eg here and here)and something I have been banging on about in my Clinical Biomechanics Boot Camps for years.That is how important I think that the concept is.
The concept has its origins in the concept of overpronation probably not be all that it is cranked up to be, so rather than focus on “overpronation” perhaps he focus should be on the forces that are associated with the function of the foot and pronation. It just makes a lot more intuitive sense o be focusing on the forces rather than the motions. It is the forces that actually do the damage to the tissues rather than motion. Motion is not painful.
I have certainly done a lot of research on it and unfortunately never quite got to publishing it. I did summarize most of the research done in this post.
Severs disease (or calcaneal apophysitis) is common in kids (my kids had it) and something that I write about often (eg here and here) and participate in lot of discussions about it.
A couple of issues have come out of all that:
1. We still do not know if the condition is due to excessive pull of the Achilles tendon or excessive ground impact on the growth plate. could be one or the other or it could be both.
2. Managing workload or activity levels is key and children are children, and they don’t listen. Sports levels can be reduced, but they still run around at school or when not being supervised.
My next thing to do on Severs is to update the PodiaPaedia entry.
You see peroneal tendinitis come up often as questions in forums, so a while back I wrote a lengthy post on it that a lot of people refer to, which is great as I really wanted to get the information out on this.
It is a condition that I often see from comments in forums that is frequently mismanaged. I do spend a lot of time on it at my Clinical Biomechanics Boot Camp course and like to tell the story about how I used to hate seeing it as my success rate used to be close to 100% failure; now its close to 100% success. The change was that dramatic once i realized what was going on with it; hence my reason for writing the blog post that I referred to above.
I have pretty much been running on and off my whole life. As of late, I have struggled a lot due to workload issues to find the time to do as much as I would like. I do plan on getting back and running another marathon within the next few years.
I have had a lot to say about running (I obviously have a blog on running) and running shoes are no exception. Usually, I have run in what is the most traditional running shoe of the time. Lately, I have been mixing it up. The evidence does support having more than one different shoe in the rotation to mix things up to load different tissues differently. This does seem to have a protective effect for injury.
Recently I have tried a couple of unusual shoes and am aware of another in the mix.
I do some of my runs in the Airia One’s and have blogged about them. This is a shoe with a lateral slant in the forefoot, zero drop and a large toe spring.
I also recently got a pair of Enko’s which is spring loaded in the heel. Running in them is certainly a very different experience. What I find intriguing in social media about these is the number of negative comments from those who have not tried them … go figure that one out.
The third shoe in the mix is the Ampla which has a spring loaded plate on the forefoot to help encourage you to run on the forefoot rather than heel strike. It came on to the market at a time that all the rhetoric and propaganda was that heel striking is evil and everyone should be forefoot striking. Turns out all that rhetoric and propaganda was wrong.
Mix it up. I do.
