AbstractTranslation of community-based functional training for older adults to reduce frailty is still lacking. We evaluated the effectiveness and implementation of a community-delivered group-based functional power training (FPT) program for frail older adults within their neighborhoods. A two-arm, multicenter assessor-blind stratified randomized controlled trial was conducted at four local senior activity centers in Singapore. Sixty-one community-dwelling older adults with low handgrip strength were randomized to intervention (IG) or control (CG) group. The IG underwent the FPT program (power and balance exercises using simple equipment) delivered by a community service provider. The 12-week program comprised 2 × 60 min sessions/week. CG continued usual activities at the centers. Functional performance, muscle strength, and frailty status were assessed at baseline and 3 months. Program implementation was evaluated using RE-AIM framework. The program was halted due to Coronavirus Disease 2019-related suspension of senior center activities. Results are reported from four centers, which completed the program. IG showed significantly greater improvement in the Short Physical Performance Battery test as compared to CG (p = 0.047). No effects were found for timed up and go test performance, muscle strength, and frailty status. The community program exhibited good reach, effectiveness, adoption, and implementation. Our study demonstrated that FPT was associated with greater improvement in physical function in pre-frail/frail participants as compared to exercise activities offered at local senior activity centers. It is a feasible intervention that can be successfully implemented for frail older adults in their neighborhoods. Trial registration ClinicalTrials.gov, NCT04438876.

Abstract Background Several trials have demonstrated the efficacy of resistance training to reduce frailty and improve function of older adults. To narrow the research-practice gap, we designed and evaluated the implementation of a community-delivered group-based functional power training (FPT) program for frail older adults within their neighbourhoods. Methods Two-arm, multicentre assessor-blind stratified randomised controlled trial at four local senior activity centres. Older adults (n = 61) with low handgrip strength (HGS) were randomised to intervention (IG) or control (CG) group. The IG underwent the FPT program (power and balance exercises using simple equipments) delivered by a community provider. The 12-week program comprised 2 × 60 mins sessions/wk. CG continued usual activities at the centres. Functional performance (SPPB and TUG), HGS, knee extensor strength (KES), and frailty status were assessed at baseline and 3-month. Program implementation was evaluated using RE-AIM framework. Results The program was halted due to Coronavirus Disease 2019 related suspension of senior centre activities. Results are reported from four centres (n = 61), which completed the program. IG showed significant improvement of moderate effect sizes in frailty status (0.36 points, 95CI [0.09, 0.64], p = 0.011) and SPPB (0.51 points, 95CI [0.13, 0.89], p = 0.010). IG improvement in TUG (0.57 s, 95CI [-0.07, 1.20], p = 0.080) did not achieve significance and there were no effects for HGS and KES. Only SPPB showed greater improvement in IG than CG (p = 0.047). The community program exhibited good reach, effectiveness, adoption, and implementation. Conclusions FPT is superior to regular activities at local senior centres in improving physical function and can be successfully implemented for frail older adults in their neighbourhoods.

Abstract Background This factorial, assessor-blinded, randomized, and controlled study compared the effects of perturbation-induced step training (lateral waist-pulls), hip muscle strengthening, and their combination, on balance performance, muscle strength, and prospective falls among older adults. Methods Community-dwelling older adults were randomized to 4 training groups. Induced step training (IST, n = 25) involved 43 progressive perturbations. Hip abduction strengthening (HST, n = 25) utilized progressive resistance exercises. Combined training (CMB, n = 25) included IST and HST, and the control performed seated flexibility/relaxation exercises (SFR, n = 27). The training involved 36 sessions for a period of 12 weeks. The primary outcomes were the number of recovery steps and first step length, and maximum hip abduction torque. Fall frequency during 12 months after training was determined. Results Overall, the number of recovery steps was reduced by 31% and depended upon the first step type. IST and CMB increased the rate of more stable single lateral steps pre- and post-training than HST and SFR who used more multiple crossover and sequential steps. The improved rate of lateral steps for CMB exceeded the control (CMB/SFR rate ratio 2.68). First step length was unchanged, and HST alone increased hip torque by 25%. Relative to SFR, the fall rate ratios (falls/person/year) [95% confidence interval] were CMB 0.26 [0.07–0.90], IST 0.44 [0.18–1.08], and HST 0.30 (0.10–0.91). Conclusions Balance performance through stepping was best improved by combining perturbation and strength training and not strengthening alone. The interventions reduced future falls by 56%–74% over the control. Lateral balance perturbation training may enhance traditional programs for fall prevention.

Background: Physical exercise is suggested to be effective for preventing cognitive decline in older adults, but the relative efficacy of different types of exercise have yet to be clarified. Objective: This single-blinded randomized controlled trial was designed to investigate the differential effects of aerobic exercise training (AT), resistance exercise training (RT), and combined exercise training (CT) on cognition in older adults with subjective memory complaints (SMC). Methods: Community-dwelling older adults with SMC (n = 415; mean age = 72.3 years old) were randomly assigned to one of the four groups: AT, RT, CT, or control group. The study consisted of two phases: a 26-week intervention and a 26-week follow-up. The participants were evaluated at baseline, 26 weeks (postintervention), and 52 weeks (follow-up). The primary outcome of this study was memory function, which was assessed using the Logical Memory II subtest of the Wechsler Memory Scale-Revised (WMS-R) score. The secondary outcomes included global cognitive function, verbal fluency, working memory, processing speed, and executive functions. Results: Intention-to-treat analysis by a mixed-effect model repeated measure showed that the AT group had significantly improved performance on the WMS-R Logical Memory II test (2.74 [1.82–3.66] points) than the control group (1.36 [0.44–2.28] points) at the postintervention assessment (p = 0.037). The effect was more pronounced in those without amnesia than those with amnesia. No significant improvement was observed in the RT and CT groups. Conclusion: This study suggests that AT intervention can improve delayed memory in community-dwelling older adults, particularly in individuals without objective memory decline.
