Vibrating machines are exercise machines with vibrating platforms that shake your body as you do strength training exercises, though you can also use them for massage and stretching. These machines increase the muscle activity in your body as you exercise on them, a study reported in the July 2010 of the "Journal of Strength Conditioning Research" noted. Exercising on a vibration machine may also give you a harder workout, increasing your oxygen intake.
Oscillating Vibration Machines
Vibration machines have either an oscillating or triplanar platform. The moving platform is the main component of a vibration machine and is the only part that vibrates. You can sit on the platform, stand on it, kneel or place your lower legs, hands or forearms on the platform to do a variety of exercises. When you do so on an oscillating vibration machine, the platform shifts up and down on each side like a seesaw. The actual distance the platform moves is minimal. At the farthest points on the sides, the platform may raise and lower less than an inch. You can control the speed that the platform moves with the control panel. Since strengthening your muscles is the goal, higher speeds work better.
Triplanar vibration machines are different than oscillating machines. The triplanar machines move in three directions or planesr. A triplanar platform moves forward and backward, side to side, and up and down all at the same time. The price of a triplanar vibration machine is higher on average. However, you can get more speed on a triplanar machine than on an oscillating machine, which is more useful for strength training because more stress is placed on your muscles. The speeds usually range from 20 Hz to 50 Hz, while oscillating machines max out at 20 Hz or less.
Mini Portable Vibration Machines
Vibration machines for strength training also come in smaller portable or miniature versions. Some machines, such as the Port-a-Vibe Portable Whole Body Vibration Machines have upright and resistance cords for upper body strength training. Other models have an upright, a console and rails so they are just smaller versions of the full-size vibration machines, while other mini machines are just the platform that can be easily picked up or stored under a bed. The mini vibration machines do not have anything for you to hold on to, but you can always place them near a wall, a high backed chair or a railing if you need help with balance. Mini and portable vibration machines are usually less expensive, though some are still fairly powerful, reaching speeds of 50 to 60 Hz.
