“It’s a topic of endless debate among runners. Is there a best way to run, so that you use the least energy and go the fastest? And does it help to run barefoot or in minimalist shoes?… Most of the scientific research is just inadequate to answer these questions, said Iain Hunter, a biomechanics researcher at Brigham Young University. Some studies have indicated that the fastest middle-distance runners — those racing between about half a mile and a mile — land on the midfoot or forefoot. But for these runners, economy — using the least amount of energy — is not an issue, because the race is so short. Last spring, Dr. Hunter saw an opportunity to get some data on elite distance runners and to determine if there is a particular style they favor. Do they hit the ground with the heel, midfoot or forefoot? Because he works with USA Track & Field, Dr. Hunter was able to get onto the field during the 10,000-meter Olympic trials. He photographed the runners’ feet with a camera that records 240 images a second. These were the fastest long-distance runners in the nation; if there is a secret to their success, he hoped the camera might show it.” w/ photo + video
