A few weeks ago I wrote a post about adidas’ new midsole technology that is being referred to as Boost. They formally introduced the Boost sole material in NYC today, and video of the event was Nike Air Max 95 Hombre streamed live. I just finished watching the video and a few things struck me. adidas is not quite as polished as Apple Nike Air Max 95 Damen when it comes to PR events like this.A lot of claims are made about the energy return provided by Boost, but very little information has been provided to back it up. It’s one thing to claim that mechanical testing shows that Boost provides more energy return than EVA, it’s another thing to demonstrate that the midsole material actually provides a performance benefit when worn by a human runner. The latter would require physiological testing of running economy in runners wearing Boost shoes vs. similar shoes with an EVA midsole. Behavior of cushioning materials in mechanical tests does not always translate to how they perform on a human – as a simple example, humans can run on surfaces that vary widely in firmness and Nike Air Max 90 Mujer produce the same amount of impact. Why? Because we adjust things like the stiffness of our legs, muscle activation,Nike Air Max 2016 Femme etc. If Boost truly does provide a performance advantage, it shouldn’t be terribly hard to demonstrate with some simple Nike Air Max 2017 Femmeexperiments.Following on the previous point, Haile Gebreselassie spoke at the event and jokingly commented that the IAAF is going to be asking adidas what’s going on with this shoe (i.e., an investigation of Boost’s performance enhancing properties – probably not what adidas wanted, or maybe it was?). This presents an interesting dilemma – if you’re adidas do you stick to marketing the energy return benefits of Boost based on mechanical testing only, or do you take the next logical step and show actual performance enhancing benefits in human runners. And, if you demonstrate the latter, might that lead Nike Air Max 90 Homme to shoes using Boost being banned from elite competition? If the shoe truly is revolutionary (and it may very well Nike Air Max 2017 Womens be), what happens if someone runs a sub-2:00 marathon in it this year or next?All of these questions are interesting to www.artealjabiri.de ponder, and will undoubtedly keep this shoes in the limelight as we head to the official release of the shoes later this month.One of the projects I’m about to get involved in is to help the PTO at my kids’ school organize their second annual 1-mile fun run. I ran the “race” last year with my children, and we all had a blast. I got to watch my oldest son blaze the first half in the lead, only to crash and burn on the uphill return trip (his pacing needs some work…). I also discovered that my 7-year old daughter has a competitive side I never knew about – an adult woman passed her heading toward the finish line and she bolted ahead and passed her right back!I was recently Facebook chatting with my columnist Nate Nike Air Vapormax Mujer Sanel about the topic of getting kids active, and as a dad he shares a similar interest in the topic. Nate has a passion Nike Air Presto Mens for topics relating to nutrition, and he asked me if I had ever seen Jamie Oliver’s TED talk about teaching kids about food. I hadn’t, and my wife and I watched it last night. It’s one of those videos that really makes you stop and think. I like to be active, but my diet is far from pristine. Sometimes I need a reminder that I need to set a better example for my kids, and Oliver’s video really hammers this home (my wife does an amazingly good job of making sure that we eat well, I wish I were more like her in this regard). |
