How robotics tech can help elite athletes get faster
Runners wearing an exoskeleton suit were able to sprint nearly one second faster over 200 metres, a recent small study found. Researcher Giuk Lee out of Seoul, South Korea, has been working with a team to create an “exosuit” that helps people sprint faster, the New Scientist reported on its website. The suit may have the potential to help elite athletes significantly improve their running performance.
Lee explains that the exosuit weighs 4.4 kg and has electrical motors on its back that control two steel cables attached to the wearer’s hips and thighs, The length of the cable running between each hip and thigh shortens as the wearer extends their legs backward, assisting them and speeding up the motion.
The team asked nine non-elite runners to sprint 200 metres to test the exosuit’s performance, twice while wearing the suit and twice without it. The participants ran 0.97 seconds faster, on average, when wearing the suit. The team has recently developed an exosuit that weighs only 2.5 kilograms and are currently investigating whether this may be a potential tool for elite athletes to use in training.
“One of the elite runners has been training with the lighter exosuit and it has helped them run faster even without wearing it,” Lee said to New Science. “This may be because it helps them to feel and remember how to engage the right muscles to run faster.”
The team is working on a customized exosuit for Kyung-soo Oh, a former national elite runner in South Korea. They’re hoping Oh will be able to beat the world record for running 100 metres while wearing the suit. Jamaican sprinter Usain Bolt holds the men’s record is 9.58 seconds, set in 2009.
This is certainly not the first time robotic science and running have crossed paths. In 2022, a U.S. start-up called Shift Robotics launched a Kickstarter campaign for what they claim is the world’s fastest shoe. The “Moonwalker” apparently lets you walk at the speed of a run while maneuvering stairs, through crowds, hills and even getting on public transit. The Moonwalker is available for the public to order now for USD $999.
