Effectiveness of a Multicomponent Training Program on Physical Performance and Muscle Quality in Older Adults: A Quasi-Experimental Study.

ABSTRACT: Aging is associated with a decrease in functional capacity, manifested by a loss of strength, physical performance and muscle quality. Multicomponent training (MCT), characterized by the combination of at least three types of training, could be a good strategy to counteract these changes. To date there are no studies evaluating the effectiveness of MCT in improving both physical performance and muscle quality simultaneously. The aim of this study is to evaluate the changes produced by an MCT program on both physical performance and muscle quality in a population of healthy older adults. Sixteen healthy older adults were recruited to perform a 15-session multicomponent training intervention. Physical performance was assessed by different functional tests, and muscle quality was assessed by tensiomyography and myotonometry. The main results of this study show some improvement in functional tests, but not in muscle quality parameters, except for vastus lateralis stiffness. MCT is able to generate improvements in the physical performance of older adults, but these improvements are not reflected in muscle quality parameters measured by tensiomyography and myotonometry.

Project description:BackgroundThe Exercise Right for Active Ageing (ERAA) program was established to improve access to exercise classes for community-dwelling older Australians. The aims of this study were to determine whether older adults, who participated in ERAA exercise classes experienced a change in physical function, and identify factors associated with this change.MethodsParticipants included community-dwelling older adults, aged ≥ 65 years, from every state and territory of Australia. The ERAA program included 12 subsidised, weekly, low- to moderate-intensity exercise classes, delivered by accredited exercise scientists or physiologists (AESs/AEPs). Primary outcomes included the 30 s Sit-to-Stand (STS) and the 3-metre Timed Up and Go (TUG) tests. Secondary outcomes included grip strength, the Chair Sit and Reach test, and waist circumference. Linear mixed-effects regression models were used to evaluate the change in outcomes following program completion, and to determine factors associated with changes in the primary outcomes.Results3,582 older adults (77% female) with a median (IQR) age of 72 (69-77) years completed follow-up testing. For all primary and secondary outcomes, there was a statistically significant improvement after program completion (p < 0.001). The STS increased by 2.2 repetitions (95% CI: 2.1, 2.3), the TUG decreased by 0.9 s (95% CI: -1.0, -0.8), right and left grip strength increased by 1.3 kg (95% CI: 1.2, 1.5) and 1.5 kg (95% CI: 1.3, 1.6), respectively, right and left reach increased by 1.7 cm (95% CI: 1.4, 2.0), and waist circumference decreased by 1.2 cm (95% CI: -1.4, -1.1). Greater improvements in STS were observed for participants aged 65-69 years, females, and those with greater socio-economic disadvantage. For the TUG, greater improvements were observed in participants reporting 2 + comorbidities, and residing in outer regional areas and areas with greater socio-economic disadvantage.ConclusionsParticipation of older Australians in the ERAA program, led to statistically significant improvements in physical function. The program reached a large number of older Australians from every state and territory, including those from regional and remote parts of Australia, aged over 85 years, and with high levels of comorbidity, which supports the feasibility and acceptability of AES- and AEP-led exercise classes amongst community-dwelling older Australians.Trial registrationAustralian New Zealand Clinical Trials Registry (ANZCTR) (ACTRN12623000483651).

Project description:BackgroundAging is associated with reduced muscle mass and strength leading to impaired physical function. Resistance training programs incorporated into older adults' real-life settings may have the potential to counteract these changes. We evaluated the effectiveness of 8 months resistance training using easily available, low cost equipment compared to physical activity counselling on physical function, muscle strength, and body composition in community-dwelling older adults receiving home care.MethodsThis open label, two-armed, parallel group, cluster randomized trial recruited older adults above 70 years (median age 86.0 (Interquartile range 80-90) years) receiving home care. Participants were randomized at cluster level to the resistance training group (RTG) or the control group (CG). The RTG trained twice a week while the CG were informed about the national recommendations for physical activity and received a motivational talk every 6th week. Outcomes were assessed at participant level at baseline, after four, and 8 months and included tests of physical function (chair rise, 8 ft-up-and-go, preferred- and maximal gait speed, and stair climb), maximal strength, rate of force development, and body composition.ResultsTwelve clusters were allocated to RTG (7 clusters, 60 participants) or CG (5 clusters, 44 participants). The number of participants analyzed was 56-64 (6-7 clusters) in RTG and 20-42 (5 clusters) in CG. After 8 months, multilevel linear mixed models showed that RTG improved in all tests of physical function and maximal leg strength (9-24%, p = 0.01-0.03) compared to CG. No effects were seen for rate of force development or body composition.ConclusionThis study show that resistance training using easily available, low cost equipment is more effective than physical activity counselling for improving physical function and maximal strength in community-dwelling older adults receiving home care.Trial registrationISRCTN1067873.

Project description:ObjectiveTo investigate the effectiveness of a guided, internet- and smartphone-based gratitude intervention on the transdiagnostic risk-factor 'repetitive negative thinking'. The multicomponent intervention integrates a variety of gratitude exercises, targeting the cognitive, emotional and behavioural facets of gratitude.MethodTwo hundred adults with pronounced repetitive negative thinking were recruited from the general population. Participants were randomly assigned to either a four-session guided gratitude intervention (n = 100) or waiting list (n = 100). The primary outcome was repetitive negative thinking three months after randomization, with exploratory assessments at six weeks and six months, the latter just for participants in the intervention group.ResultsFollowing the intention-to-treat principle, by analyses of covariance (ANCOVA), the gratitude intervention group exhibited significantly lower levels of repetitive negative thinking than controls at three months, with d = 0.66, 95 % CI [0.37, 0.94] maintained at six-month follow-up. Significant and meaningful beneficial effects were observed in symptoms of depression (d = 0.42) and generalized anxiety (d = 0.38). These effects were notably stronger in intervention completers who finished at least three sessions.ConclusionsResults suggest that a multicomponent gratitude intervention is effective at reducing repetitive negative thinking. Multicomponent interventions may be a next step needed to fully realize the potential of gratitude interventions. Such interventions could expand the repertoire of transdiagnostic interventions, especially for repetitive negative thinking. Furthermore, due to its positive connotations, gratitude is a candidate for an indirect intervention aimed at reducing the burden of depression in the general population.Trial registrationThe study is registered in the German Clinical Trial Register (approved primary register of the WHO) as DRKS00006825.

Project description:BackgroundEthiopia was among the 15 countries that, together accounted for 64% of the world's severe episodes of pneumonia among children below the age of 5 in 2011. To reduce this burden, the 10-valent pneumococcal conjugate vaccine (PCV 10) was introduced into the general childhood national immunization program in Ethiopia in 2011. However, there is little evidence on its cost-effectiveness, and the aim of this study was to estimate the cost-effectiveness of the introduction of PCV 10 vaccination in the Ethiopian setting.MethodsThe cost-effectiveness analysis was carried out based on a quasi-experimental evaluation of implementing PCV 10 at the Butajira rural health program site in Ethiopia. The intervention and the control groups consisted 876 and 1010 children, respectively. Using data from program site's surveillance system database as a framework, health outcome and vaccination data were collected from medical records, immunization registration books and reports. Disability- Adjusted Life Year (DALY) was a main health outcome metric complimented by incidence of acute lower respiratory infection/1000-person years. Vaccination and treatment costs were collected by document review and cross-sectional household survey.ResultsIn the intervention cohort, 626 of 876 (71.5%) children received PCV 10 vaccination. Until the first year of life, the incidence of acute lower respiratory infection was higher in the intervention group. After the first year of life, the incidence rate was 35.2 per 1000-person years in the intervention group compared to 60.4 per 1000-person years in the control group. The incremental cost-effectiveness ratio (ICER) per averted DALY for the intervention group during the total follow-up period was (2013 US$) 394.3 (undiscounted) and 413.8 (discounted). The ICER per averted DALY excluding the first year of life was (2013 US$) 225 (undiscounted) and 292.7 (discounted).ConclusionCompared to the WHO's suggested cost-effectiveness threshold value, the results indicate that the general childhood PCV 10 vaccination was a cost-effective intervention in the Butajira rural health program site.
