Context. Physical activity is important for the management of metabolic functions; however, little is known whether performing home-based moderate-intensity exercise (MIE) obtains further improvement on metabolic functions in adults with non-communicable diseases (NCDs) who already perform regular gym-based MIE. Objective. The purpose of this study was to examine the effect of adding home-based MIE on metabolic functions in older adults with NCDs who have regularly performed gym-based MIE. Design. This was a single-center randomized controlled study. The observation period was set for 24 weeks. Subjects and Methods. Twenty-one older adults (age, 60–79 years) with uncomplicated NCDs, who have performed 30–40 min MIE, 2–3 days/week at a hospital gym for over 1 year, were randomly divided into two groups: performing home-based MIE, comprising aerobic and resistance exercises, at least 20 min/day, 3 days/week (HOME, n = 11), or not performing home-based MIE (CON, n = 10). All participants completed the study and continued their gym-based MIE as usual. Results. After 24 weeks, there were no significant differences in the values of any outcomes. Conversely, the decrease in waist circumference (WC) was larger in the HOME group (–2.17 [–3.98, –0.36] cm) than in the CON group (0.57 [–1.42, 2.56] cm) (p < 0.05), although not in other outcomes. Conclusions. Although further studies are needed, we found that adding home-based MIE had a positive effect on WC, but little effect on other metabolic functions in older adults with NCDs who have continued regular gym-based MIE.
