Engineers have developed a microchip muscle stimulator that can be implanted into the spinal canal, allowing paraplegics to exercise paralyzed muscles, ScienceDaily reports.
The implant, which is the size of a child's fingernail, is the first device small enough to be inserted into the spinal canal and contains electrodes and muscle stimulator in one, providing better and more muscle stimulation.
"Stimulation of more muscle groups means users can perform enough movement to carry out controlled exercise such as cycling or rowing," said Professor Andreas Demosthenous, who led the project.
According to ScienceDaily, the chip could also be used to restore functions such as bladder stimulation and suppress spasms.
"When walking the same distance, short people burn more calories per pound of body weight than do tall people," writes Science, because short people have to work harder to get there by taking more steps.
For the study titled Why Big People Walk More Economically Than Small People, researchers measured the metabolism and biomechanics of 48 children and adults as the subjects walked on a treadmill. Everyone burned the same amount of calories per pound per step, but the children had to take more steps to cover the same distance.
Don't worry, tall people, you still have a metabolic advantage. Chances are your basal metabolic rate-- the minimum amount of calories you need to function--is higher than that of your short friend.
Tchicaya Missamou, once a child soldier in the Republic of Congo, is now helping hundreds of Americans shape up in his Warrior Fitness Camp in California, CNN reports.
As a child in the Republic of Congo, Missamou was taught brutality and forced to participate in taking lives. Later, he joined the country's elite military force. To avoid fighting, he began a private security militia that helped white families flee during the Republic of Congo's civil war in 1997, though even his own men turned against him and brutalized his family, setting fire to their home while some were still inside. Missamou managed to escape and fled to the United States.
Missamou quickly joined the U.S. military and was soon leading men into battle in Iraq. After eight years of service and a harrowing return to the Republic of Congo that landed him in jail there, Missamou opened his gym, offering "warrior" classes to help Americans shed pounds and gain self-confidence.
"You're going to see them rolling, sweating, and crying," he told CNN. His tough training style includes spraying clients with water as they don a full military pack and pull dollies piled with tractor tires. "My workout is a mind game," he says, "because I believe when your mind is strong, your body will be strong."
Missamou, who recently published his memoir In the Shadow of Freedom, also lectures around the country on the plight of child soldiers in Africa, CNN says. "All my life, I lived in the shadow of freedom," he told CNN. Now, "I am not dreaming freedom. I am living freedom."
