Now for the Science!
Muscular Strength increases in two ways.
* Neurological Adaptatio * Muscular Adaptation and Hypertrophy
Muscular adaptations occur through an increase in the cross sectional area of muscle fibers improving the contraction properties of muscle tissue leading to a maximal contraction that provides more force and power.
Muscle hypertrophy (Muscle hypertrophy involves an increase in size of skeletal muscle through an increase in the size of its component cells) usually begins after 4 to 6 weeks of training.
Vibration training accelerates strength through Neurological adaptation, which means that strength will increase through improvements of the quality of muscle contractions. For an untrained individual there is a definite lack of control in muscle fibers. MRI's have shown that the whole muscle is not used during a maximal contraction during exertion. Whole Body Vibration there is nearly 100% Recruitment of muscle fibers therefore allowing an accelerated improvement in initial strength
