Effects Of Vibration Training On Elderly Women Balance And Tower Limb Strength

Objective: This study of the impact of the elderly lower extremity strength and balance tests related indicators, the changes observed indicators discussed vibration training on elderly women balance and lower limb intervention force and effect, as well as effective in the elderly as a reasonable exercise provide reference and basis.Research Methods: 40 elderly women(menopause 2- more than 3 years) subjects were randomly divided into two groups(experimental group, n = 20 people in the control group, n = 20 people, half the control group lost due to other personal reasons, control Found 15 people group, the experimental group of 20 people), mean aged 62.17 ± 6.93, the average height was 156.21 ± 8.34 cm, training methods: the experimental group Power Plate vibration training device(US) for a period of three months, week 3 times, every 30 minutes(1min × 15 groups, each batch 1min), the frequency of 35 Hz, the amplitude of vibration training 2mm. The control group had no training, maintaining a normal lifestyle. Detection Indicator: one leg stance, standing still with eyes closed, sitting 5(Five Times Sit to Stand Test, FTSST), stand up- go(Timed Up and Go Test, TUGT), balance and stability coefficient, coefficient proprioception, shift the focus of the amplitude balance and lower limb strength index and so on. Statistics: Using SPSS 19.0 software for statistical analysis, data obtained by mean ± standard deviation of the way that the use of paired samples T-test values within the group for statistical analysis, independent sample T-test statistical analysis on the set of values, a significant difference is expressed as P <0.05, significant difference is expressed as P <0.01.Results: After 12 weeks experiment(1) experimental group one leg stance time eyes after marking time before the experiment were higher compared with the experiment, was highly significant difference(P <0.01), the control group was not significant difference; previous experiments have also been experimental group TUGT experiments to improve and showed significant differences(P <0.05), no significant difference between the control group; the experimental group, the experimental visual adjustment coefficient, balance and stability coefficient and balance index compared with the experiment after experiment before have been improved and showed a highly significant difference(P <0.01), no significant difference between the control group; although the decrease compared with before the experiment after experiment shift the focus of the magnitude and proprioceptive factor experiment but there was no significant difference(P> 0.05) the control group had no significant difference.(2) lower limb strength in the experimental group after the size of the experiment than before experiment: lower extremity strength has improved significantly, showing very significant difference(P <0.01), no significant difference between the control group; the experimental group FTSST after the experiment than before the experiment showed a significant difference(P <0.05), no significant difference in the control group.Conclusions: After 12 weeks of training, the subjects of balance and stability coefficient, balance and visual index adjustment coefficient after the experiment was significantly improved, indicating that vibration training can significantly improve the balance in elderly women, prevent falls in the elderly, thereby reducing the risk of falls and fractures caused posed. Lower extremity strength of the size of the subject has been significantly improved, indicating that vibration training for middle-aged women have to enhance the role of lower extremity strength and prolonged recession, while the middle-aged women in motor function to enhance the overall effect.
