The Benefits of Backward Running

Backward running will never be mistaken for the natural way of running, but there are some indications that backward running enables people to avoid or recover from common injuries, burn extra calories and sharpen balance while mixing up their daily routine.

The scientists published their findings in the Proceedings of the Royal Society B: Biological Sciences.[1] Training with backward running is quite different than usual running. As expected, it was discovered that runners struck the ground near the back of their feet when going forward, and rolled onto the front of their feet for takeoff. When they were going backward, they landed near the front of their feet and took off from the heels. They tended to lean slightly forward, even when running backward. As a result, their muscles fired differently. In forward running, the muscles and tendons were pulled taught during landing and responded by coiling, which creates elastic energy that is released during toe-off. When running backward, muscles and tendons were coiled during landing and stretched at takeoff. The backward runners’ legs didn’t benefit from stored elastic energy in their muscles

Running backward required 30% more energy than running forward at the same speed. Backward running also produced far less hard pounding. Giovanni Cavagna, a professor at the University of Milan who led the study, states that reverse running can potentially “improve forward running by allowing greater and safer training.”

In a second study, researchers found that runners with bad knees also benefited from backward running because it causes far less impact to the front of the knees. And it burns more calories. In a third study, active female college students who replaced their exercise with jogging backward, 15 to 45 minutes three times a week for six week lost almost 2.5% of their body fat.

It has some drawbacks, like not being able to see where you’re going, so it should be done on a track or treadmill at a slow speed to start.
