There's a whole lot of shaking going on in gyms these days. The machines responsible may look like locker room scales on steroids, and the idea of using them to jiggle the flab away may seem a bit wacky. But experts, celebrities and true believers say that squatting and pressing atop these vibrating platforms can perk up tired bodies and ignite weary workouts. “Vibration training improves muscle tone and increases core body temperature because it allows for stimulation of the neurological system,” David Harris, director of personal training for the Equinox Fitness, said in an interview. Over 100 gyms in the United States and more than 80 countries worldwide feature the vibrating platforms, according to Patty Stapleton, spokesperson for Power Plate, the California-based company which manufactures them. Model and television presenter Heidi Klum, actors Clint Eastwood and George Clooney, and entertainers P-Diddy and Madonna are among its celebrity users, according to the company. “Many people are using the machines to improve flexibility and reduce muscle soreness,” Fabio Comana, an exercise physiologist and spokesperson for the American Council on Exercise (ACE), said in an interview. The principles of whole-body vibration therapy were originally developed for the Russian space program to combat the degenerating effects of zero gravity on muscle and bone. Scientists found that vibrating therapy allowed cosmonauts to stay in space for up to three months longer. Russian Olympic trainers began using it in the 1970's to improve their athletes' competitive edge, and in 1999 Dutch trainer Gus Van de Meer designed a device for the fitness community. But really the technology reaches back much further - to 1687 and Sir Isaac Newton's second law of motion. “It works on Newton's principle where force equals mass times acceleration,” Comana explained. “The vibration activates neurological systems and muscle response. It also places stress on the bones to increase their density and it certainly stimulates blood flow, improves flexibility and reduces muscle soreness,” he said.
