Video (21:53) Summary (from the website):Sharing powerful stories from his anti-obesity project in Huntington, W. Va., TED Prize winner Jamie Oliver makes the case for an all-out assault on our ignorance of food. N.B.: video is al vertaald in 40 talen (o.a. Nederlands)! Why you should listen to him: Jamie Oliver has been drawn to the kitchen since he was a child working in his father's pub-restaurant. He showed not only a precocious culinary talent but also a passion for creating (and talking about) fresh, honest, delicious food. In the past decade, the shaggy-haired "Naked Chef" of late-'90s BBC2 has built a worldwide media conglomerate of TV shows, books, cookware and magazines, all based on a formula of simple, unpretentious food that invites everyone to get busy in the kitchen. And as much as his cooking is generous, so is his business model -- his Fifteen Foundation, for instance, trains young chefs from challenged backgrounds to run four of his restaurants. Now, Oliver is using his fame and charm to bring attention to the changes that Brits and Americans need to make in their lifestyles and diet. Campaigns such as Jamie's School Dinner, Ministry of Food and Food Revolution USA combine Oliver's culinary tools, cookbooks and television, with serious activism and community organizing -- to create change on both the individual and governmental level. vu=http://video.ted.com/talks/dynamic/JamieOliver_2010-medium.mp4&su=http://images.ted.com/images/ted/tedindex/embed-posters/JamieOliver-2010.embed_thumbnail.jpg&vw=432&vh=240&ap=0&ti=765&introDuration=15330&adDuration=4000&postAdDurat

From: Miriam van Reijen & Marko Heneweer, October 2010. Summary (from the article): Running economy (RE) is one of the most important factors that determine superior performance in elite long distance runners. The ability to run at high speeds while using a minimum of energy allows runners to spare the limited amount of muscle glycogen. Conclusion In summary, no differences were found in running economy between long and short distance or in running economy at one absolute and five relative velocities. Out of a number of anthropometric variables measured, moment arm of the Achilles and BMI are most predictive of the variation in running economy in this heterogeneous group of runners. Training volume shows a complex, but important relationship with running economy.
