Working with a band between your toes would possibly sound ridiculous, but it surely may make you noticeably extra environment friendly. In a Stanford-led research, printed within the Journal of Experimental Biologyresearchers discovered that this silly-looking setup helped runners use about six per cent much less vitality. Is it a trick value making an attempt? Right here’s what you should know.
Mechanical engineer Elliot Hawkes, now on the College of Calif., Santa Barbara, first had the concept whereas biking previous a operating observe in San Francisco, as reported in science information outlet phys.org. Watching runners push via their strides, he seen how a lot vitality gave the impression to be misplaced with every step. That sparked a query: may a fundamental piece of stretchy tubing—like surgical resistance banding—make operating extra environment friendly?
A literal spring in your step
To scale back the trouble it takes to swing the legs whereas operating, Hawkes and his crew examined a easy setup utilizing a brief piece of surgical tubing, clipped between runners’ sneakers. This “exotendon” labored like a spring, storing and returning vitality with every stride, very like the tendons in a cheetah’s legs.
Earlier than bringing it to the observe, the researchers measured how a lot vitality the band may return in a lab take a look at. Stretched from 30 to 70 centimeters and hooked up to a weight, the band rebounded with 97 per cent effectivity—exceptional for such an on a regular basis materials. As soon as runners tried it, the advantages turned clear. With much less muscular effort wanted to maneuver their legs, they naturally adopted faster, lighter steps, enhancing effectivity with none change in kind or acutely aware effort.

One small band for giant beneficial properties
In complete, 19 wholesome younger adults took half within the research. None had accidents or situations that may intrude with their stride. Whereas the setup seemed unusual, the difference was practically instantaneous—not solely did runners keep away from tripping or tangling, however additionally they confirmed a median 6.4 per cent enchancment in effectivity. In response to Hawkes, the band additionally made it simpler to bounce off the bottom throughout every footstrike, which is a serious supply of vitality loss in operating.
Earlier than you strive it
The model used within the research was reduce to a few quarter of every runner’s leg size—brief sufficient to remain away from tangles, lengthy sufficient to not snap. The exams have been all executed on flat, paved surfaces, and the impact didn’t appear to stay after the band got here off. In different phrases, this isn’t a coaching software that teaches higher kind; it’s extra like an assistive gadget. You received’t be sporting it as you chase your half-marathon PB. Nonetheless, for anybody curious, it could be value experimenting. As Hawkes put it, “Somebody in contrast it to an electrical bicycle, the place you simply go quicker, so it’s enjoyable.”
