Abstract
With the burgeoning elderly population, there is an escalating demand for effective and safe exercise programs to enhance physical performance and avert age-related complications. This study aimed to evaluate the effects of a whole-body vibration (WBV) exercise program on the physical performance and postural balance of older adults. The study enlisted 21 participants aged 65 and older, divided into three groups: WBV, foam mat (FM), and control. Over four weeks, participants engaged in a structured exercise regimen designed to improve lower limb muscle strength, cardiovascular endurance, flexibility, coordination, and postural balance. The low-impact, elderly-friendly program included resistance exercises tailored to each group’s conditions. Pre- and post-program evaluations comprised physical performance tests (chair stand, 2[Formula: see text]-min step, chair sit-and-reach, figure-of-8 walk) and postural balance assessments (limit of stability (LOS), Timed Up and Go (TUG), One Leg Stance (OLS)). Results showed significant improvements across all groups, with the WBV group exhibiting the most pronounced enhancements. WBV group improvements included a 62.8% increase in lower-limb muscle strength and a 31.7% rise in cardiovascular endurance. The WBV group also demonstrated the greatest advancements in postural stability and dynamic balance, as indicated by significant changes in OLS and TUG test times. These findings suggest WBV exercises can effectively enhance physical performance and balance in older adults, presenting a promising alternative to traditional exercise programs that may impose greater physical burdens. Further research with larger sample sizes and controlled variables is recommended to confirm these benefits and refine WBV exercise protocols.
