spring-heeled: concept that could see usain bolt rocket to 50mph | science

A wearable spring-based contraption that attaches to the legs has the potential to boost human running speeds by 50%, according to researchers who hope to build the first prototype over the next year.Scientists came up with the concept after computer models showed that it was possible to dramatically increase the amount of energy people put into each running step by enabling them to do work when their feet are in the air.The device, which leads to what the researchers concede is an “unconventional means of running”, could set the stage for a new Olympic sport, they believe, and be adopted by police forces and emergency rescue teams. According to the scientists’ calculations, if Usain Bolt mastered the contraption, his top speed would rocket from 27.8mph to nearly 50mph.“We wanted to see what physics allows and then explore it further by developing a device,” said David Braun, an engineer who works on human augmentation at Vanderbilt University in Nashville, Tennessee.“This shows us how far we can push the boundaries and what key features we should focus on to develop the new technology.”Braun hit on the idea after studying the mechanics of running and cycling. While the fastest human running speed on the flat is close to 28mph, the equivalent top cycling speed is nearer 50mph. Much of the difference is due to bicycles being in contact with the ground the whole time and the pedalling mechanism which allows the rider to power along constantly.“When you look at world-record running, the foot is on the ground only 20% of the time, so for 80% of the time it is in the air and not providing any energy for motion,” Braun said.FacebookTwitterPinterest Illustration: Amanda Sutrisno and David J.
