“…Almost half of the participants (46%) continued RT during the 1‐year follow‐up at least once‐a‐week. The continuation rate is similar to the studies by Geirsdottir et al., in which ~18% of participants continued RT once‐ or twice‐a‐week and ~24% ≥three times‐a‐week, and Inaba et al., in which 43% continued RT at least once‐a‐week. In both studies the continuation was measured by self‐reports.…”

The aim of this study was to investigate the effects of a 9-month supervised resistance training intervention on motivational and volitional characteristics related to exercise, and whether the absolute level and/or intervention-induced change in these characteristics predict self-directed continuation of resistance training 1 year after the intervention. Community dwelling older adults aged 65-75, who did not fulfill physical activity recommendations, were randomized into resistance training intervention groups: training once- (n = 26), twice- (n = 27), three-times-a-week (n = 28) or non-training control group (n = 25). Training groups participated in supervised resistance training for 9 months: during months 1-3 all groups trained twice-a-week and then with allocated frequencies during months 4-9. Exercise-related motivation, self-efficacy, and planning were measured with questionnaires at baseline, month-3 and month-9. The continuance of resistance training was determined by interviews 6 and 12 months after the end of the intervention. The intervention improved action and coping planning as well as intrinsic motivation (group × time P < .05). During 1-year follow-up, 54% of participants did not continue self-directed regular resistance training, 22% continued regular resistance training once-a-week, and 24% twice-a-week. Increases in exercise self-efficacy and intrinsic motivation related to training during the intervention predicted continuation of resistance training twice-a-week. Resistance training improved exercise-related motivational and volitional characteristics in older adults. These improvements were linked to continuing resistance training 1 year after the supervised intervention. The role of these characteristics should be taken into account when promoting long-term resistance training participation among older adults.

“…This is similar to another report tracking changes after supervised exercise training in which 80% of older adult participants were physically active during the 6‐ to 18‐month follow‐up period . However, in the present study, only 19% of participants reported to be participating in RES exercise training, compared to 42% maintaining unsupervised RES exercise training in this other report . Our findings mirror previous work where the long‐term maintenance of any newly acquired behavior, including exercise, is challenging .…”

“…Many participants (91%) continued to participate in planned exercise to some extent, and 73% of the participants achieved the frequency (three times per week) prescribed in the supervised intervention. This is similar to another report tracking changes after supervised exercise training in which 80% of older adult participants were physically active during the 6‐ to 18‐month follow‐up period . However, in the present study, only 19% of participants reported to be participating in RES exercise training, compared to 42% maintaining unsupervised RES exercise training in this other report .…”

BACKGROUND/OBJECTIVE Barriers and facilitators of exercise maintenance and residual effects of exercise training intervention on physical and cognitive function after the cessation of training are inadequately described in older adults. DESIGN AND SETTING One year after the cessation of a supervised exercise training intervention, a mixed methods approach employed a quantitative phase that assessed body composition and physical and cognitive function and a qualitative phase that explored determinants of exercise maintenance after participation in the intervention. PARTICIPANTS Community‐dwelling older Irish adults (aged >65 years) who had completed 12 weeks of supervised exercise training 1 year previously. MEASUREMENTS Fifty‐three participants (male/female ratio = 30:23; age = 70.8 ± 3.9 years) completed the follow‐up testing comprising body composition and physical and cognitive function. Semistructured interviews were conducted with 12 participants (male/female ratio = 6:6) using the Theoretical Domains Framework to inform the interview guide. RESULTS At 1 year follow‐up, body fat increased (mean = 4.3%; 95% confidence limit = 2.2% to 6.3%), while lean body mass (mean = −0.6%; 95% confidence limit = −1.2% to −0.1%), strength (leg press, mean = −5.6%; 95% confidence limit = −8.3% to −2.8%; chest press, mean = −11.0%; 95% confidence limit = −14.8% to −7.8%), and cognitive function (mean = −3.7%; 95% confidence limit = −5.7% to −1.8%) declined (all P < .05). Interviews revealed key facilitators (social aspects and beliefs about benefits of exercise) and barriers (affordability and general aversion to gyms) to exercise maintenance in this population. CONCLUSION Key barriers and facilitators to exercise maintenance were identified, which will inform the development of future behavior change interventions to support exercise participation and maintenance in older adults to mitigate adverse changes in body composition and physical and cognitive function with advancing age.

“…In addition, to maintain or improve muscle function, older adults must continue their physical exercise. Several reports have indicated that even if the muscle function is improved by resistance training, it will gradually decline during the detraining period in older adults [12,13,14,15]. Thus, there is a possibility that the physical function was maintained or improved by consecutive mild physical exercise in older adults who attended the community-based self-management group.…”

Preventing frailty and its adverse health outcomes is crucial in countries with a large elderly population, such as Japan. Since the long-term care insurance (LTCI) system was launched, the number of certified older adults with LTCI service requirement has continued to increase. This is a serious problem, because the LTCI service requirement certification is equivalent to disability. The aim of this study was to evaluate the effect of a self-management group intervention on new LTCI service requirement certifications in community-dwelling older adults in Japan. We analyzed the cohort data from a prospective study. In this study, we recruited community-dwelling adults aged 65 years and older who were independent in a city in Kyoto prefecture in 2012. The subjects in the participation group (n = 1620) attended 60-min group training sessions once or twice every two weeks from December 2012 to December 2016. The exercise sessions consisted of mild-intensity aerobic exercise, mild strength training, flexibility and balance exercises, and cool-down activities. These exercise classes were facilitated by well-trained volunteer staff. The outcome measure was the number of new LTCI requirement certifications during a four-year follow-up period. During the four-year follow-up period, 247 subjects (15.2%) in the participation group and 334 (20.6%) in the control group were newly certified for LTCI service requirements. The hazard ratio for new LTCI service requirements in the participation group compared with the control group was 0.73 (95% CI = 0.62–0.86) in the four-year follow-up period. These results indicate the usefulness of self-management group exercise to reduce the incidence of disability in older adults. Thus, increasing self-management group activities in each community should be encouraged.
