Abstract
BackgroundStudies have shown that sarcopenia easily leads to difficulty moving, disability, and poor quality of life. However, researches on the use of whole-body vibration for older adults with sarcopenia living in institutions have been lacking. Therefore, the main objective of the present study was to investigate the effect of whole-body vibration intervention on improving the skeletal muscle mass index, physical fitness, and quality of life of older adults with sarcopenia living in institutions.MethodsThis study adopted a quasi-experimental, single-group, pretest-posttest design. The whole-body vibration intervention was performed over a 3-month period, in which the older adults trained 3 times per week; each training lasted 60 s with a break of 30 s for 10 repetitions. The older adults’ skeletal muscle mass index, physical fitness and quality of life before and after the intervention of the whole-body vibration was collected. Concerning the statistical methods adopted, nonparametric method-based tests were employed.ResultsAccording to the results of analysis, after the intervention of the 12-week whole-body vibration, the skeletal muscle mass index (z = − 3.621, p = 0.000), physical fitness on standing on one foot (z = − 2.447, p = 0.014), shoulder–arm flexibility (z = − 3.159, p = 0.002), 8-ft up and go test (z = − 2.692, p = 0.009), hand grip strength (z = − 3.388, p = 0.009), and five repeated sit-to-stand tests (z = − 2.936, p = 0.003), all improved significantly. Furthermore, concerning the quality of life of the older adults in the pretest and posttest, the improvements were statistically significant (z = − 2.533, p = 0.011).ConclusionsThe study results showed the effect of whole-body vibration intervention on improving the skeletal muscle mass index, physical fitness, and quality of life of sarcopenic older people living in institutions and could serve as a crucial reference to health care professionals.
Highlights
Studies have shown that sarcopenia leads to difficulty moving, disability, and poor quality of life
The present study first investigated the demographics, skeletal muscle mass index (SMMI), physical fitness, and quality of life of sarcopenic older people living in institutions
Demographics, SMMI, physical fitness, and quality of life among sarcopenic older people Adults aged older than 65 who lived in nursing homes and had sarcopenia were included in this study
Summary
Studies have shown that sarcopenia leads to difficulty moving, disability, and poor quality of life. The main objective of the present study was to investigate the effect of whole-body vibration intervention on improving the skeletal muscle mass index, physical fitness, and quality of life of older adults with sarcopenia living in institutions. The increase in the average life expectancy of the Taiwanese population and the nation’s annual national average fertility rate continues to decrease; ageing society becomes an irreversible trend. The International Working Group on Sarcopenia argued that sarcopenia denotes the combination of muscle loss and a decline in physical performance [3]. Beaudart et al [6] conducted a systematic review and meta-analysis of the health outcomes of sarcopenia Their results showed high rates of mortality, functional decline, falls, and hospitalizations among older people with sarcopenia
