The purpose of the present study was to evaluate the effects of a dance intervention associated with resistance training or health education program on functional paramaters and quality of life of aging women. Thirty-six women were allocated to dance plus resistance training group (D + RT) or dance plus health education group (D + HE). Both interventions lasted 8 weeks and were performed twice a week. Dance sessions lasted 60 min. Resistance training was composed by two to three sets of 10-15 repetitions in five exercises. Improvements were found in 30-s chair stand (D + RT: 6 ± 1 repetitions; D + HE: 7 ± 1 repetitions), 30-s arm curl (D + RT: 7 ± 1 repetitions; D + HE: 7 ± 1 repetitions), 6-min walk (D + RT: 43 ± 12 m; D + HE: 55 ± 12 m), timed up and go (D + RT: -1.1 ± 0.3 s; D + HE: -1.4 ± 0.2 s), and psychological domain of quality of life (D + RT: 6 ± 2%; D + HE: 5 ± 3%), with no difference between groups. Both groups improve functional parameters and quality of life of aging women.

Issues relating to older adults in sport are ongoing topics of interest among sport scientists; however, our knowledge on how older athletes have been studied is incomplete, which has implications for understanding the comprehensiveness of this evidence base. This scoping review aimed to provide an overview of how sport and older adults have been studied since the first World Masters Games. Data on research topics, research methods, sport-specific information, and demographic information on older athletes were collected and reviewed. Results suggest older athletes who are White, male, and competitive athletes have largely been the focus of research. In addition, results highlight an alarming number of unreported data related to the demographics of athlete samples. As a result, the well-documented benefits of sport may reflect a homogenous group of older adults, limiting our overall understanding of aging and sport and the value of this research for developing evidence-informed policy.

Sex-related differences in changes in functional fitness over time were longitudinally assessed in older adults participating in a group-based multimodal exercise program. From a database, functional fitness scores were obtained for 89 older adults (71.6 ± 6.5 years old) who had completed two assessments, 5-8 years apart. Lower body strength, upper body strength, aerobic endurance, flexibility, and change of direction performances were compared over time and with normative values. Females (p = .02), but not males, had an improvement in upper body strength over time. Females were also more flexible than males at both assessments (p ≤ .02). Of those who had five consecutive assessments, females were more flexible than males (p ≤ .05) and had a faster change of direction ability (p < .001). When compared with normative values, our results indicate that typical time-related functional fitness loss can be attenuated with group exercise. Our results further support the need to tailor exercise prescription according to the individual.

Mild cognitive impairment is an intermediate state between the cognitive decline often experienced in normal aging and dementia that affects 15% of Americans over 65 years of age. Our communities have an opportunity to support the development and adoption of evidence-based programs to help older adults preserve cognition and physical function. In partnership with a local urban YMCA in an underserved, predominantly minority neighborhood, we tested the appeal and therapeutic benefits of SMARTfit training among older adults with mild cognitive impairment. The participants reported a positive training experience. After 12 weeks of dual-task training, Trail-Making Test and Stroop Color-Word Interference Test scores improved, as did scores on the Short Physical Performance Battery. Results of our SMARTfit dual-task training intervention are encouraging. Larger randomized controlled trials must further investigate the development, implementation, and therapeutic impacts of SMARTfit dual-task training on cognitive and physical function in aging.
轻度认知障碍是介于正常衰老和痴呆症之间的一种中间状态,65岁以上的美国人中有15%患有痴呆症。我们的社区有机会支持基于证据的项目的发展和采用,以帮助老年人保持认知和身体功能。在一个服务不足、以少数族裔为主的社区,我们与当地的一个城市基督教青年会(YMCA)合作,测试了SMARTfit训练对轻度认知障碍的老年人的吸引力和治疗效果。参与者报告了积极的训练经历。经过12周的双任务训练,trail making Test和Stroop Color-Word Interference Test的得分有所提高,Short Physical Performance Battery的得分也有所提高。我们的SMARTfit双任务训练干预的结果令人鼓舞。更大规模的随机对照试验必须进一步研究SMARTfit双任务训练对老年人认知和身体功能的发展、实施和治疗影响。

Aging is associated with neurodegeneration and a loss of muscle function, especially in lower-limb muscles. While caffeine may augment muscle force generation through multiple effects on the central nervous system, no studies have yet compared the effects of caffeine on force-generating capacity between younger and older men, who might respond differently due to age-related changes in the structures on which caffeine acts. In a double-blind, controlled trial, 22 younger (25 ± 5 years) and 21 older (68 ± 6 years) men were tested for isometric plantarflexor torque on two separate days (2-7 days apart) before and 60 min after ingesting 3 mg/kg (∼2 cups of coffee) of caffeine or placebo. No effects of caffeine ingestion on peak torque or rate of torque development were detected in either older or younger men. Therefore, 3 mg/kg of caffeine may not acutely counteract age-related decreases in force capacity of the functionally important plantarflexor muscles.

This randomized controlled trial (NCT03475316) examined the relative efficacy of 6 months of social ballroom dancing and treadmill walking on a composite executive function score, generated from digit symbol substitution test, flanker interference, and walking while talking tasks. Brain activation during functional magnetic resonance imaging (fMRI) versions of these executive function tasks were secondary outcomes. Twenty-five dementia-at-risk older adults (memory impairment screen score of ≥3 to ≤6 and/or an Alzheimer's disease-8 Dementia Screening Interview of ≥1) were randomized in June 2019 to March 2020-16 completed the intervention before study termination due to the COVID-19 (eight in each group). Composite executive function scores improved post-intervention in both groups, but there was no evidence for between-group differences. Social dancing, however, generated greater improvements on digit symbol substitution test than treadmill walking. No intervention-related differences were observed in brain activation-although less hippocampal atrophy (tertiary) was observed following social dancing than treadmill walking. These preliminary findings are promising but need to be confirmed in future large-scale and sufficiently powered randomized controlled trials.

External connectivity refers to the service opportunities provided by community open spaces that are influenced by the factors such as traffic distance, road conditions, residence patterns, and population distribution. It is an important factor in determining access to community open spaces. This has important implications for promoting walking behavior and community physical activity among aging urban populations. Using the accessibility evaluation method, we proposed an external connectivity of the community open spaces model from the community perspective and conducted an empirical study using the Overseas Chinese Town community in Shenzhen as an example. External connectivity of the community open spaces can be used to evaluate the efficiency of community open spaces, serving as a reference for open space optimization. Moreover, it has applicable value in promoting physical activity and healthy aging among older adults.

Little is known about older adults' physical exercise destinations. We studied associations between physical activity (PA) level and physical exercise destinations (total number and surrounding environment) in community-dwelling 75- to 85-year-old adults living in Central Finland. Participants (N = 901) reported the amount of at least moderate-intensity PA and physical exercise destinations. Distance from home, land use, and locations of sport facilities were defined using a geographic information system. A general linear model showed that older adults with higher PA reported higher numbers of physical exercise destinations and destinations further away from home than those reporting lower PA. Binary logistic regression showed that higher PA increased the odds of reporting a distant destination identified as a sports facility and of reporting destinations located in residential, service, forest, and water body areas, respectively. Physical exercise destinations in different environments may attract older people to go out and be more physically active.

This study examined the relationship between loneliness, sedentary behavior, physical exercise, and social participation in Chinese older adults, and provided ideas to formulate preventive strategies that can help reduce loneliness. Data on demographics, health behavior, social participation, and loneliness were collected from a cross-sectional study of 629 older adults in Hefei, Anhui province, from June to August 2020. After adjusting for age, income, religion, marital status, and chronic illness demographic variables, sedentary behavior (β = 0.111, SE = 0.671, p = .001), physical exercise (β = -0.229, SE = 0.358, p < .001), and social participation (β = -0.329, SE = 0.086, p < .001) were found to be significantly correlated with loneliness in older adults. These findings suggest that a higher level of loneliness may be linked to greater sedentary behavior, less social engagement, and decreased physical exercise among older men and women.
本研究探讨了中国老年人孤独感、久坐行为、体育锻炼和社会参与之间的关系,并为制定有助于减少孤独感的预防策略提供了思路。2020年6月至8月,对安徽省合肥市629名老年人进行了一项横断面研究,收集了人口统计学、健康行为、社会参与和孤独感方面的数据。在调整了年龄、收入、宗教、婚姻状况和慢性病人口统计变量后,发现久坐行为(β = 0.111, SE = 0.671, p = .001)、体育锻炼(β = -0.229, SE = 0.358, p < .001)和社会参与(β = -0.329, SE = 0.086, p < .001)与老年人孤独感显著相关。这些发现表明,在老年男性和女性中,较高程度的孤独感可能与久坐行为增多、社交活动减少和体育锻炼减少有关。
