ABSTRACT
Objective:
To systematically evaluate the dose-response relationships of resistance exercise intensity in frail elderly.Methods:
A comprehensive search of randomized controlled trials on the dose-response relationships of resistance exercise for frail elderly in PubMed, Embase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang Database. The documents that met the conditions were screened out, and after the data were extracted and the quality of the documents were evaluated, the RevMan 5.3 software was used for Meta analysis.Results:
A total of 10 eligible randomized controlled trials were included in this study. The subjects of the study were 454 cases of frail and pre-frail elderly. After Meta analysis, there was a dose-response relationships between the training intensity of resistance exercise and the muscle strength, muscle endurance, and physical function of frail elderly. Both low-intensity and high-intensity resistance exercises can significantly increase the leg muscle strength of frail elderly people ( MD=4.58, 95% CI 3.34-5.82, P<0.05) and muscle endurance ( MD=12.27, 95% CI 6.54-17.99, P<0.05). Compared with low-intensity resistance exercise, high-intensity resistance exercise increased leg muscle strength of frail elderly people ( MD=7.97, 95% CI 0.85-15.09, P<0.05) and muscle endurance ( MD=6.94, 95% CI 5.21-8.66, P<0.05) showed more obvious advantages. The analysis of the results of the chair sitting test and the stairs climbing test shows that low-intensity resistance exercise has no obvious advantage in improving the physical function of frail elderly people, while high-intensity resistance exercise can significantly improve the physical function of frail elderly people ( MD=-5.8, 95% CI -7.3--4.29, P<0.05; MD=-1.20, 95% CI-2.17--0.23, P<0.05).Conclusions:
Resistance exercise can significantly improve the muscle strength, muscle endurance and physical function of the frail elderly. High-intensity resistance exercise is more effective than low-intensity resistance exercise.
