Sprint faster, jump higher, increase power; That’s why French Olympic top sprinters Mark Raquil (400m) and Patricia Girard (100mH) have chosen for Whole Body Vibration (WBV) Machines ! That’s why Djibril Cissé, French top scorer (2002 & 2004), formal Auxerre and this season playing for Liverpool FC has chosen to train on Whole Body Vibration (WBV) Machines. Indeed, all those athletes have been convinced by the benefits of Whole Body Vibration (WBV) Machines since about three months. Why? To appreciate the value of Whole Body Vibration (WBV) Machines training to help athletes increase speed, increase jump performance, power and agility let’s briefly discusses some basic anatomical principles of muscular contraction. To start with, all skeletal muscles consist of three main fiber types. These fiber types are listed below:

1. Slow twitch fibers- Responsible for the strength and endurance of a muscle.
2. Intermediate twitch fibers- Possess qualities of both slow and fast twitch fibers.
3. Fast twitch fibers- Responsible for the speed of muscular contraction.
   All of these fibers types are arranged into groups known as “motor units”. There are many motor units within the overall muscle. But, when a muscle begins to contract, only some of the motor units become active. As the demand on the muscle increases, more and more motor units are recruited to help support this demand.

Training on HyperGravity Fit-N-Flex Whole Body Vibration (WBV) Machines, involves tensing muscles against other muscles, muscles are stimulated to contraction by means of the vertical vibrations! Effective Whole Body Vibration training for explosive performance is achieved when the muscle tension is maintained over a certain period of time. Thus, training on HyperGravity Fit-N-Flex Whole Body Vibration (WBV) Machines for explosive purposes is best defined as – The sustained contraction of a muscle over a certain period of time, where vibrations stimulate maximum the motor units. The biggest advantage of Whole Body Vibration for explosive training is two fold. By forcing your muscle(s) to hold a position on the vibration plate for a certain length of time, your body will begin to recruit and activate more and more motor units to help maintain this contraction. Motor units that are rarely exercised within a particular muscle are now brought into use, perhaps for
the first time. As the vibrations continue, the motor units that are recruited are forced to contract continuously, time after time, with no appreciable decrease in force output. This allows your muscles to achieve a state of maximum contraction safely and effectively. The end result is that the entire muscle matures very quickly.
