Coasting : Issue 2 2009
Physiotherapist and Pilates Instructor, Lisa Anthony demonstrating Pilates exercises using the Power Plate machine at Central Coast Pilates Physioxtra at Erina. Scientists not convinced - yet Dr Xanne Janse de Jonge, program convenor of Exercise and Sport Science at the University of Newcastle’s Ourimbah campus said more research needed to be done on the effectiveness and the potential dangers of whole body vibration training machines. “I think they have some applications but it’s important to realise that the science behind them is not really well understood yet,” Dr Janse de Jonge (pictured below) said. “Some studies have shown that muscle activation increases when they are used and, of course, that has been taken on board by the companies that produce them and they can use that in their sales pitches. But in order to really fi nd out what happens, a lot more research is needed. to balance. You don’t need to know how to bring those muscles into play, your body does it subconsciously.” Ms Anthony said it was an effi cient method of exercise. “In a 30-second period if you have the Power Plate set on 30 hertz you have 900 muscle reactions, so what happens, very effi ciently, is you’re getting a lot of muscle work. It’s useful for core stability work-outs but it’s also working the nervous system.” But there’s more to using a vibrating plate machine than standing and jiggling for half an hour. A user can also hold different positions, such as squats, push-ups, lunges and stretches, for about 30 seconds at a time to work various parts of the body. It’s not like a full-on work-out but it still works the muscles, the heart and the lungs. “You wouldn’t get as much of a cardio work-out as running on a treadmill but after 15 minutes on this I am a little bit breathless, I am hot, sweaty. It’s an increased load on your heart because your circulation goes whoosh,” Ms Anthony said. Ms Anthony said she had fi rst approached the machine with doubts. “I was sceptical in the beginning, but the results are there,” she said. And it was ideal for the type of work she does with injured or recovering clients. “I like it because it’s safe, it’s effi cient and if you’re injured you can still work hard.” “You need to fi nd the right balance between what would be dangerous - because vibration can be a dangerous thing for the body - and getting results. “From the sports science side we’re just not sure yet what really is happening inside the muscles and body.” Erina 4367 6447 Morisset 4973 3606 Toronto 4950 5225 www.nswmowers.com.au c8554830-4Jun Parsons now selling more than John Deere Parsons John Deere Mowers – We now sell Tractors to suit any lifestyle Full range of john deere hats now available to buy online at www.nswmowers.com.au
