Effects of Whole-body Vibration Exercise on Balance Ability and Lower Extremity Muscle Strength in Elderly Women

This paper sets to study on the effect of long-term vibration training on elderly women's dynamic and static balance ability and lower limb muscle endurance, so as to provide intervention measures for the prevention of falls in the elderly. With the American Power-Plate tester, 13 women aged 5565 years old were trained in 24 weeks, 3 times/week, 25 min/(frequency 30-40 Hz, amplitude 3 mm). The Balance Good tester was used to test the dynamic and static balance ability of the subjects, and the knee and ankle flexion and extension (60/S, 180/S IsoMed) were used to test the knee and ankle joint strength. The results show that 24 weeks of high frequency vibration training has improved elderly women's static and dynamic balance ability, and the improvement is especially obvious on the left and right direction. At the same time, there are also varying degrees of improvement on the absolute power of knee and ankle flexor and extensor, explosive force and endurance. Therefore, whole body vibration training can be used as an effective method to improve the balance ability and endurance of the elderly people. It is also a feasible exercise for the elderly to prevent falls and those who are not used to active exercises.
