Despite the well-known benefits of physical activity, less than half of adults aged 55-75 years participate in sufficient physical activity. Short bouts of vigorous intermittent lifestyle physical activity (VILPA) accumulated throughout the day can contribute toward the recommended volume of physical activity. A rich characterization of the barriers and facilitators to participation in VILPA is needed to develop targeted interventions. This scoping review aimed to identify barriers and facilitators to participation in different components of VILPA in adults aged 55-75 years, and to map barriers and facilitators to the Theoretical Domains Framework. Within the 18 eligible studies, the most prevalent barriers were related to a person's skills, environmental context, and social influences. Most facilitators were related to a person's goals, social influences, and environmental context. Interventions to promote VILPA should test the effectiveness of behavioral change measures related to the unique barriers and facilitators in this age group.

The aim of this study was to quantify physical activity and sedentary behavior in older adults recovering from hip fracture and to identify groups based on movement patterns. In this cross-sectional cohort study, older adults (≥70 years) were included 3 months after surgery for proximal femoral fracture. Patients received an accelerometer for 7 days. Demographics and outcomes related to physical function, mobility, cognitive functions, quality of life, and hip fracture were assessed. In total, 43 patients with sufficient accelerometer wear time were included. Across all groups, participants engaged in very low levels of physical activity, spending an average of 11 hr/day in prolonged sedentary behavior. Based on the extracted components from a principal component analysis, three groups with substantial differences in levels of physical activity and sedentary behavior could be distinguished.

The aim of this study was to determine factors associated with participation of community-dwelling older Australians (≥65 years) in the Exercise Right for Active Ageing program, consisting of 12 low- to moderate-intensity group exercise classes, delivered weekly, in person or online, by accredited exercise scientists and physiologists across Australia. Out of 6,949 participants recruited, 6,626 (95%) attended one or more classes and were included in the primary analysis, and 49% of participants attended all 12 classes. Factors associated with higher class attendance included participation in yoga/flexibility/mobility classes, attendance at a free trial class (adjusted incidence rate ratio [95% confidence interval]: 1.05 [1.03, 1.08]), and attending online classes (1.19 [1.11, 1.26]). Factors associated with lower class attendance included state of residence, living in inner regional areas (0.95 [0.93, 0.98]), and having two or more comorbidities (0.97 [0.95, 0.99]). High class attendance suggests that the Exercise Right for Active Ageing program was well received by older Australians, particularly in states less impacted by COVID-19 lockdowns.

Introduction: COVID-19 caused major disruptions across the super-aged nation of Japan, yet few studies explored temporal changes among middle-aged and older cohorts from baseline to the height of community transmission. Changes in physical activity and sedentary behavior during global pandemics may alter patterns of morbidity and mortality among susceptible aging populations.

Objectives: This study investigated patterns of physical activity, sitting behavior, and health among representative samples of middle-aged and older adults in Tokyo before and during the pandemic.

Methods: Repeated online surveys were conducted with quota samples of 800 Tokyo residents in 2019 and 2021 using validated Japanese-language measures, including the short form-International Physical Activity Questionnaire and the Basic Ecological Health Scale-6. Statistical analyses included comparative evaluations of activity parameters by age cohort, gender, and selected covariates. Statistical tests included the Kruskal-Wallis test, Mann-Whitney U test, chi-square test for Independence and Hierarchical Regression.

Results: Over 34% of respondents were inactive at each data collection point, and 72% reported negative impacts of COVID-19 on their physical activities. Older adults showed no significant changes in their activity and sitting behavior and reported better health compared with those in middle age across the pandemic. Middle-aged males reported a significant decline in total activity of 33% across the pandemic period (U = 16,958, z = -2.64, p = .008, r = .13). Middle-aged females reported the lowest levels of physical activity, and health, and showed a 29% increase in sitting behavior across the pandemic (U = 16,925, z = -2.68, p = .007, r = .13). Subjective health status was consistently associated with higher overall activity and walking before and during the pandemic.

Conclusion: Differential outcomes were identified between age and gender regarding health, physical activity, walking, and sitting across the pandemic with significantly worse impacts reported among middle-aged samples.

Implications: These results have implications for healthy transitions to later life and the design of postpandemic interventions to address activity opportunities in Japan.

Many studies have shown that personalized exergames have a positive effect on promoting regular and proper exercise. However, there is no consensus on the design characteristics and evaluation of exergames. This systematic review of published research literature aimed to explore the general characteristics, personalization characteristics, and evaluation of personalized exergames for middle-aged and older people. We screened published studies in the Web of Science, Scopus, PubMed, ACM, and IEEE Xplore databases, extracted data, and performed a thematic analysis according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist. Three main themes and nine subthemes were generated from 24 included papers. Moreover, a personalization model (FACTS) and evaluation system (PMSS) of exergames were developed. Personalized exergames had potential positive effects on motivating middle-aged and older people to exercise and improve their health, particularly physical, mental, and social health. However, more fine-grained studies on personalized exergames are necessary in the future.

Knowledge of how the different types of sedentary behaviors (SB) are associated with functional limitations can guide professionals who work with older adults on better recommendations about the amount of daily time that should be encouraged in each type of SB. The objective was to estimate the associations between two SB typologies (SB television [TV] and SB computer/internet) and the presence of handgrip strength, lower limb strength, gait speed, and balance limitations in Brazilian community-dwelling older adults. This is a cross-sectional study with 1,298 community-dwelling older adults (≥60 years). SB was assessed by self-reporting daily time spent watching TV or using computer/internet (categorized into <2, 3-4, and ≥5 hr/day). Outcomes were handgrip strength, lower limb strength, gait speed, and balance limitations considering referenced cutoff points. Older adults in SB TV ≥5 hr/day had 1.75 (95% confidence interval [CI] [1.07, 2.86]) and 1.88 (95% CI [1.02, 3.46]) times more chances of handgrip strength and gait speed limitations, respectively. On the other hand, those who spent 3-4 and ≥5 hr/day in SB computer/internet had 0.45 (95% CI [0.20, 0.99]) and 0.37 (95% CI [0.15, 0.93]) had less chances of lower limb strength and balance limitations, respectively. In conclusion, functional limitations would be associated differently depending on the type of SB in the older adults sampled.

To investigate how frailty modifies the association of sitting time with all-cause and cardiovascular mortality in Chilean adults. This prospective study included 2,604 participants aged ≥35 from the Chilean National Health Survey 2009-2010. Sitting time was self-reported, while frailty was assessed using a 36-item Frailty Index. Sitting time was categorized as low, medium, and high. Cox proportional hazard models were used to estimate the risk of mortality stratified for the sitting time categories. Over a median follow-up of 8.9 years, 311 participants died, 28% of them due to cardiovascular events. Frail people with prolonged sitting time were at higher risk of all-cause and cardiovascular mortality (hazard ratio 3.13; 95% confidence interval [2.06, 4.71] and hazard ratio 2.41; 95% confidence interval [1.50, 3.64], respectively). The observed risk was higher in women than men. Public health and individual strategies should be implemented to decrease sitting time across the population, with special attention on frail people.

This study investigated the impact of multimorbidity patterns on physical activity and capacity outcomes over the course of a year-long exercise intervention, and on physical activity 1 year later. Participants were 314 physically inactive community-dwelling men and women aged 70-85 years, with no contraindications for exercise at baseline. Physical activity was self-reported. Physical capacity measurements included five-time chair-stand time, 6-minute walking distance, and maximal isometric knee-extension strength. The intervention included supervised and home-based strength, balance, and walking exercises. Multimorbidity patterns comprised physician-diagnosed chronic disease conditions as a predictor cluster and body mass index as a measure of obesity. Multimorbidity patterns explained 0%-12% of baseline variance and 0%-3% of the change in outcomes. The magnitude and direction of the impact of unique conditions varied by outcome, time point, and sex. Multimorbid older adults with no contraindications for exercise may benefit from multimodal physical training.

Physical activity (PA) and physical function (PF) are modifiable risk factors for falls in older adults, but their ability to predict future fall incidence is unclear. The purpose of this study was to determine the predictive ability of baseline measures of PA, PF, and lower limb strength on future falls. A total of 104 participants underwent baseline assessments of PA, PF, and lower limb strength. Falls were monitored prospectively for 12 months. Eighteen participants fell at least once during the 12-month follow-up. Participants recorded almost exclusively sedentary levels of activity. PA, PF, and lower limb strength did not differ between fallers and nonfallers. Twelve participants, who reported a minor musculoskeletal injury in the past 6 months, experienced a fall. The results of this study suggest that in a cohort of highly functioning, sedentary older adults, PA does not distinguish fallers from nonfallers and that the presence of a recent musculoskeletal injury appears to be a possible risk factor for falling.
