EXOSKELETON' ''

THEY ASKED THE STUDENTS to run on treadmills for 10 minutes at a steady pace of around 9 minutes per mile while wearing the device and-

And without it as the scientists monitored their energy expenditure. And the found that the men were much more efficient with the device, reducing the energy cost of their running by about 8 percent.

That should mean that someone wearing device would be able to run longer.faster or more easily 

By comparison, the much-touted NIKE high-performance running shoe, the Vaporfly 4%, is said to improve running efficiency by stated 4 percent.

A NEWLY invented wearable device could provide support, succor and an unexpected boost in speed to runners who might otherwise not be able-

To keep up with their training partners or former selves, as well as people who might like to try running but fear it is just too hard.

The device, a kind of lightweight harness worn around the midsection and legs, can increase running efficiency by 8 percent or more, according to a new study, making running feel much easier and also raising interesting questions about whether and how we should augment natural human abilities.

In recent years, biomechanics labs around the world have been experimenting with various devices meant to ease the difficulties of moving for both people and their silicon counterparts, robots.

Because walking is such a fundamental form of movement for independence and health, most of this past research has been directed towards that activity.

The research has generally focused on various types of what the scientists call 'exoskeletons', although the devices often are localised to specific joints.

Some use batteries or other energy sources to provide extra power, which can compensate for weakness in someone's body. Others are unpowered and reinforce or amplify whatever force people wearing them can generate.

Recently, Rezvan Nasiri, a graduate student at the Cognitive Systems Laboratory at the University of Tehran in Iran, began to wonder about running.

A competitor in Judo, Mr. Nasiri was jogging one evening to try to maintain his weight for a coming meet when he began to pay close attention to his stride. ''I realized that each ground impact, my legs lost energy,'' he said

This recognition was not really a surprise. Experts in biomechanics long have known that running can be somewhat wasteful motion .

We create energy when we coil our muscles and push off with one leg from the ground and dissipate some of it when our foot returns to the pavement and momentum is slightly braked.

Jogging along, Mr. Nasiri began to consider whether it might be possible to to harness some of that squandered energy. If so, he reasoned, the key would be work with the hips.

Much of the action to running involves our hips, which are far more important during this activity than during walking Mr. Nasiri finished his run, returned to the lab the next day and, with the help of colleagues began to tinker.

What he and his collaborators hoped to do was, in essence, couple a runner's hips in a way that nature has not, so that-

So that the energy created by one leg as it completes a swing and moves backwards might be sent over to the other leg as it starts forward, reducing the activity required of that hip's muscles and decreasing the overall energy costs of running.
