Le rapport du Colorado a été sponsorisé par Nike, ce qui va amener certains à jeter un ?il sceptique sur les Nike Air Max 90 Femme Blanche résultats. La réponse de Kram: "Nike est venu à nous parce que nous pouvions concevoir Nike Air Max 90 Femme une étude pare-balles, et j'ai beaucoup d'expertise et d'intégrité reconnue dans le domaine. L'argent n'est pas allé à moi. Il a payé mes étudiants post-doc et dipl?més, et nous avons rémunéré les sujets pour leur temps. Il n'y a aucun moyen que je risquais ma réputation scientifique batie sur 34 ans Nike Air Odyssey Femme pour fabriquer des résultats. C'était juste un projet totalement cool. J'Nike Roshe Run Womens adore ce genre de choses. ?La dernière chaussure de course haut de gamme de Nike, la Zoom Vaporfly 4%, porte bien son nom, selon une nouvelle étude menée par des chercheurs de l'Université du Colorado.
Des chercheurs du laboratoire de locomotion de CU à Boulder ont découvert que la chaussure réduisait le co?t énergétique de la course de 4% en moyenne pendant les tests sur tapis Nike Air Max Tavas Womensroulant.
Quatre pour cent d'économies d'énergie pourraient ne pas sembler un gros Nike Air Max 90 Damen Schwarz problème. Mais pour les coureurs d'élite, qui essaient de réduire de quelques fractions d'un pour cent de leur temps de course à la poursuite de la barrière du marathon de deux heures, cela pourrait être une percée, selon les chercheurs.
"Si vous regardez comment le record du monde du marathon a évolué au Nike Air Presto Femme cours des dernières années, nous avons obtenu 3% de plus rapide sur 30 Nike Air Max 2016 Damen ans", a déclaré Wouter Hoogkamer, un chercheur postdoctoral qui a dirigé l'étude au laboratoire Nike Air Max 90 Damen de locomotion. "Et tout à coup, vous avez une chaussure qui vous donne 4 pour cent d'économies d'énergie."
"Les gens vont nous crier dessus pour avoir dit cela", a déclaré Rodger Kram, professeur de physiologie intégrative et auteur de l'étude. De nombreux facteurs peuvent affecter la Nike Air Max Classic BW Mens performance d'un coureur: vent, nutrition, virages, collines.
"Ces chaussures Nike Air Presto Womens réduisent l'énergie dont vous avez besoin pour rouler à une certaine vitesse", a-t-il déclaré. "Mais si vous portez ces chaussures et ne buvez pas d'eau pendant 26 miles, ce ne sera pas les chaussures qui expliqueront pourquoi vous n'avez pas couru en moins de deux heures."
the Nike brass convene in the Innovation Kitchen for what amounts to a high-stakes game of show-and-tell. Designers and engineers bring the prototypes for projects they’re working on, and top executives will consult, criticize, and question their progress. In January 2015, the HyperAdapt team brought their latest iteration into one of the Kitchen’s conference rooms. Beers, who’d been working nonstop since Hatfield’s NBA All-Star bombshell, had finally taken a vacation, and assuming her place was Eric Avar, another heralded Nike Nike Air Max 1 Damen designer and Hatfield protégé, Nike Air Max 90 Homme Noir best known for his designs bearing Kobe Nike Air Max 90 Donne Rosa Bryant’s name. As Avar wrapped up his presentation, the panel began eviscerating the entire project. They questioned just about everything. At bottom, Beers says, they doubted that the shoe had any real athletic benefit. Even more terrifying, they were unsure whether work on it should even continue. (Skepticism was and is hardly limited to inside Nike—in the wider industry, gimmick is a word that gets thrown around, and the Reebok Pump is sometimes dismissively referenced. “I look at it as more of a PR thing, not as true innovation,” says Peter Rueegger, a leading footwear-industry consultant who has worked with Nike in the past. And Mike Friton, a former Nike designer who worked closely with Beers on the project in its early stages around 2007, questions the Nike Air Max 2017 Womens environmental impact and Nike Air Huarache Mujer sustainability of a shoe packed with Nike Air Max 1 Hombre electronics. “To me, it was kind of running Nike Air Max 90 Mens backward in that sense.”)When she returned, Beers once again did not panic. The panel’s feedback coaxed her team to focus on improving the HyperAdapt’s basic proposition: It could help protect athletes’ feet, and that, in turn, could help the athletes feel better and play better. “I was like, OK, we have to build more prototypes,” Beers says. “We have to have more people try it out, we have to prove it with numbers. We have to put the proof on the table.” With the help of Nike Sports Research Lab, a testing facility that measures human performance and collects data to shape the design and engineering, she conducted multiple rounds of what’s internally called perception testing. Beers put HyperAdapt prototypes on test subjects and had them go through a kind of Nike Air Max 95 Womens CrossFit training routine, and Nike Air Max Thea Womens after their workouts they answered surveys Nike Air Presto Womens about their shoe experience. She also stepped up dynamic wear testing, where she asked runners and basketball players to wear the shoes and give her feedback on how their feet felt during and after their workouts.

Charlotte Hornets: Frank Kaminsky sprained his right ankle in Wednesday's game against Golden State and limped straight to the locker room after the injury occurred. He has been ruled out for Friday's home game against Chicago, and with Cody Zeller now out indefinitely due to a torn medial meniscus in his left knee, the Hornets will need to lean heavily on the starting frontcourt of Marvin Williams and Dwight Howard going forward. Not good.Chicago Bulls: According to the Chicago Tribune, Zach LaVine likely will make his season debut next month -- not in December, as some had speculated earlier in the season. Mike McGraw reports that coach Fred Hoiberg wants LaVine to go through 10 to 14 days of practicing every other day, followed by 10 consecutive days of practice before he returns to game action. Look for LaVine to eat into Justin Holiday's and Denzel Valentine's minutes once he's able to get back on the court.Cleveland Cavaliers: Ready for another Tristan Thompson update? The Cavs hope to have their rebound specialist back before the end of the week, ESPN's Dave McMenamin reported on Wednesday. Thompson has been out since the first day of November due to a calf injury, and his return will alter the roles of Kevin Love and Jae Crowder, so be aware of that.Dallas Mavericks: Dennis Smith Jr. sat out Thursday's practice due to a sore hip, per Mavs writer Eddie Sefko, and while the injury is "not believed to be anything serious," it could keep the athletic rookie point guard out of Friday's game against Milwaukee. If Smith doesn't play, J.J. Barea, Devin Harris and Yogi Ferrell will each take on a bigger role against the Bucks.Denver Nuggets: The Nuggets' defense has been in shambles lately due in large part to the losses of Paul Millsap and Nikola Jokic. Denver enters Thursday all the way down at No. 25 in the league in defensive efficiency, which has to be hard to take for the team's defensive-minded coach, Michael Malone. Right now is a great time to use players who are going up against the Nuggets, whether in daily or season-long leagues.
