Home-based resistance training for older adults: A systematic review

Home-based resistance exercise is commonly used for individuals who might not have access or the ability to use traditional resistance exercise. However, the extent to which home-based resistance exercise can improve both strength and functional ability has not been investigated in healthy older individuals using a systematic analysis. The current article systematically reviewed the effectiveness of home-based resistance exercise on strength and functional ability. Search engines included Academic Search Premier, CINAHL, PubMed, PsycINFO, MEDLINE, SPORTDiscus and Web of Science. A total of 649 articles were found using the key words home-based and strength and older or elderly, with eight articles meeting the final criteria. The average age of the participants was 76years, with the average duration of exercise training ranging from 8weeks to 120weeks. Of the eight studies, a significant increase in knee extension strength was found in five studies. Functional ability significantly improved in seven of the eight studies, with the average decrease in Timed Up & Go test being -0.8 +/- 0.5s. Three studies included greater amounts of supervised visits compared with the other five studies (approximate to 51% vs approximate to 7%). The more supervised studies had significant increases in strength and functional ability. Overall, home-based resistance exercise can improve both strength and functional ability, but the improvements are generally small. The intensity of the exercises might not progress sufficiently enough to produce large improvements in strength as a result of less supervision or a lack of motivation to increase the intensity further.
