The premise in vibration training is simple. The fitness machines are equipped with a vibrating plate that users exercise on to stimulate muscle contractions at a rate so fast (between 20 and 60 times per second) that the body experiences the effects of a full-on, strenuous workout in a fraction of the time.
Vibration training dates back to the 1960s, when Russian scientists developed the machines to help cosmonauts combat the effects of a decrease in muscle mass and bone density from the lack of gravity in space. Its benefits were next used in Russian ballet and, later, by big names such as former cyclist Lance Armstrong and the NBA.
Vibration training made its Hong Kong debut in 2007 when Andrew Cox, master trainer for the US-based National Academy of Sports Medicine, introduced the Power Plate brand of machines to Innate Fitness, a company he founded. Two other brands, TurboSonic and iShape, became available last year.
It works, says Dr Billy Law Kin-yip, of the faculty of medicine at the Hong Kong Jockey Club Sports Medicine and Health Sciences Centre. He adds: 'Vibration training benefits those who haven't exercised regularly more than those who are normally active.'
Because of its low-impact nature, it is an ideal form of exercise for the elderly, Law says. 'In fact, several hospitals ... have these machines.'
With each brand of machines claiming superiority, we decided to give them a go.
