Scientists in the fields of exercise physiology, physical therapy, and other related fields have been examining physical interventions that can maintain and even increase functional performance as we age. In this quest to improve "functional age" a number of factors have been identified as important targets to maintain independence, increase mobility, and prevent catastrophic injuries (such as falls). Among the most important of these factors are: muscular power and strength, flexibility, agility, bone density, and body composition. Although exercise interventions have proven effective in addressing each of these factors, these interventions are generally time-consuming and labor intensive. Whole body vibration (WBV) has been studied for many years as a training tool to increase a multitude of the factors associated with performance. This paper will examine the physics and physiology of whole body vibration (WBV) and its reported impact on physical changes associated with the aging process.
