COLUMBUS, Ohio — Forget “slow and steady wins the race.” A new study shows that, at least sometimes, the best way to conserve energy and reach your destination on time is to alternate between walking and running—whether your goal is the bus stop or a marathon finish line.

In the January 30, 2013 issue of the Journal of the Royal Society Interface, researchers examined how people budget their time as they travel on foot to reach a destination at a particular appointed time. The study found that when people have neither too much time nor too little time to reach their destination, they naturally switch back and forth between walking and running, which turns out to be the best strategy for saving energy.

Exercise May Lead to Better School Performance for Kids with ADHD

EAST LANSING, Mich. — A few minutes of exercise can help children with attention deficit hyperactivity disorder perform better academically, according to a new study led by a Michigan State University researcher.

The study, published in the current issue of the Journal of Pediatrics, shows for the first time that kids with ADHD can better drown out distractions and focus on a task after a single bout of exercise. Scientists say such “inhibitory control” is the main challenge faced by people with the disorder. (more…)

Hips Take Walking in Stride; Ankles Put Best Foot Forward in Run

In a first-of-its-kind study comparing human walking and running motions – and whether the hips, knees or ankles are the most important power sources for these motions – researchers at North Carolina State University show that the hips generate more of the power when people walk, but the ankles generate more of the power when humans run. Knees provide approximately one-fifth or less of walking or running power.

The research could help inform the best ways of building assistive or prosthetic devices for humans, or constructing next-generation robotics, say NC State biomedical engineers Drs. Dominic Farris and Gregory Sawicki. The co-authors of a study on the mechanics of walking and running in the journal Interface, a Royal Society scientific journal, Sawicki and Farris are part of NC State’s Human PoWeR (Physiology of Wearable Robotics) Lab.
