Kolata goes on to report data from studies showing that elites at the Olympic Trials land in all kinds of different ways (true), and reports on studies that show no significant difference between foot strikes in terms of efficiency (also true). I’ve got no problem with any of this.
My Nike Air Max 2017 Damen main issues Nike Air Max 90 Femme with the article are the following:
It’s fine to ask if there is a best way to run from an economy and speed standpoint, but I think that it also bears mentioning that the form that let’s you run fastest may not be the form that minimizes your injury risk.Many of us like and want to run fast, but would prioritize our health over performance in a race. Plenty of runners could care less about racing, so economy and speed matter very little. Granted, she was very open in writing the article with a focus on economy and speed, but she also writes “Proponents say barefoot running is more natural — humans evolved to run without shoes — and economical.” Maybe some barefoot proponents claim this with regard to economy, but most of the barefoot runners I know started doing it simply because they hurt less when they take their Nike Air Max 2016 Donne shoes off.The Nike Air Max 2017 Womens article was overly foot-centric. Foot strike is but one aspect of gait, and my guess is that if you looked at other aspects of form you’d see a lot more similarity among the elites when compared to more recreational runners (e.g., hip extension, limb position on landing, etc.). Part of the problem with the form debate over the past few years is that it has focused way too much on the foot, ignoring other, perhaps more important aspects of gait. I am just as guilty of this as anyone else, but it’s time to take the foot off it’s EVA cushioned throne and take a broader view of form.Some statements are misleading. For example, she writes that “…studies have repeatedly shown that when people try to change their natural running style, they tend to use more energy to cover the same distance.” Well, that’s because Nike Air Max 90 Womens most Nike Air Max 270 Womens studies that look at things like this look at short or even instantaneous form changes. They take a runner, have them run in their normal form, then ask them to force some change and make a comparison. Any new motor pattern is going to take time to learn, and until it is learned I’d fully expect it to be less efficient!Furthermore, ignoring speed/economy, multiple studies have shown that gait retraining can provide benefits in terms of reducing limb loading, reducing pain, and in some cases can resolve long-term injuries – it may not make you more efficient, but in some cases changing form is the only way people have be able to keep running. Any running at all is going to be faster than sitting on the couch.Regarding Rodger Kram’s barefoot/shod study (which I wrote about here), Kolata says:“In a study published this year, www.josielloyd.co.uk Dr. Kram Nike Air Max 270 Womens and his students found that runners who wore very lightweight shoes were more efficient than those who ran barefoot. (The barefoot runners wore weights on their feet to mimic the weight of the shoes, so that this would not be a factor in the results.)”The important point here is that the study actually showed that running fully barefoot was not significantly different in terms of economy from running in a lightweight shoe. It was only when weights equivalent to the weight of the shoe were added that “barefoot” became less economical.
