Advanced age is associated with degenerative changes in body composition. There is evidence suggesting that changes may vary upon differences in lifestyle, environment, or gender. Physical activity engagement is considered an important component of lifestyle definition. There are suggestions that engaging in physical activity might alleviate degenerative body compositional changes. The objective is to assess the relationship between adherence to recommended guidelines of physical activity and anthropometric parameters in Israeli older adults. Anthropometric measures, including height, weight, and waist circumference, were taken, and BMI was calculated, from a random sample of 1,663 elderly adults (799 men and 864 women), aged 74.31 (±6.05) years old. Participants reported their physical activity habits and, based on official guidelines recommendations, they were divided into sufficiently active, insufficiently active, and inactive groups. One-way ANOVA (level of physical activity) for both genders was conducted for each anthropometric variable. In both genders, an association between level of physical activity and weight, waist circumference, and BMI was found, with lower values among the sufficiently active. In addition, a relationship between level of physical activity and height was indicated among women, implying that the more active women were taller than the less active. In addition to the already known health benefits of physical activity in old age, it is possible that adherence to recommended guidelines of physical activity is associated with favorable anthropometric characteristics.  相似文献

Exercise programs are often recommended for preventing or delaying late-life disability. Programs that incorporate functional training, which uses movements similar to performing activities of daily living, may be suitable for such recommendation. The purpose of this systematic review was to examine the effects of functional training on muscle strength, physical functioning, and activities of daily living in older adults. Studies in three electronic databases (MEDLINE, CINAHL, and SPORTDiscus) were searched, screened, and appraised. Thirteen studies were included in the review. These studies vary greatly in participant recruitment criteria, functional training content, and selection of comparison groups. Mobility exercises were the most common element in functional training across studies. Results show beneficial effects on muscle strength, balance, mobility, and activities of daily living, particularly when the training content was specific to that outcome. Functional training may be used to improve functional performance in older adults.  相似文献

Background

Older adults are encouraged to participate in regular physical activity to counter the age-related declines in physical and cognitive health. Literature on the effect of different exercise training modalities (aerobic vs resistance) on these health-related outcomes is not only sparse, but results are inconsistent. In general, it is believed that exercise has a positive effect on executive cognitive function, possibly because of the physiological adaptations through increases in fitness. Indications are that high-intensity interval training is a potent stimulus to improve cardiovascular fitness, even in older adults; however, its effect on cognitive function has not been studied before.Therefore, the purpose of this study was to compare the effects of resistance training, high-intensity aerobic interval training and moderate continuous aerobic training on the cognitive and physical functioning of healthy older adults.

Methods

Sixty-seven inactive individuals (55 to 75 years) were randomly assigned to a resistance training (RT) group (n = 22), high-intensity aerobic interval training (HIIT) group (n = 13), moderate continuous aerobic training (MCT) group (n = 13) and a control (CON) group (n = 19) for a period of 16 weeks. Cognitive function was assessed with a Stroop task and physical function with the Timed-Up-and-Go (TUG) and submaximal Bruce treadmill tests.

Results

No significant GROUP x TIME interaction was found for Stroop reaction time (P > .05). The HIIT group showed the greatest practical significant improvement in reaction time on the information processing task, i.e. Stroop Neutral (ES = 1.11). MCT group participants had very large practical significant improvements in reaction time on the executive cognitive tasks, i.e. Stroop Incongruent and Interference (ES = 1.28 and 1.31, respectively). The HIIT group showed the largest practically significant increase in measures of physical function, i.e. walking endurance (ES = 0.91) and functional mobility (ES = 0.36).

Conclusions

MCT and RT proved to be superior to HIIT for the enhancement of older individuals’ executive cognitive function; whereas HIIT were most beneficial for improvement in information processing speed. HIIT also induced the largest gains in physical function.

Background

Physical exercise (PE), virtual reality-based exercise (VRE), and brain exercise (BE) can influence physical and cognitive conditions in older persons. However, it is not known which of the three types of exercises provide the best effects on physical and cognitive status, and which exercise is preferred by older persons. This study compared the effects of PE, VRE, and BE on balance, muscle strength, cognition, and fall concern. In addition, exercise effort perception and contentment in older persons was evaluated.

Methods

Eighty-four older persons (n?=?84) were randomly selected for PE, VRE, BE, and control groups. The exercise groups received 8-week training, whereas the control group did not. Balance was assessed by Berg Balance Scale (BBS) and Timed Up and Go test (TUG), muscle strength by 5 Times Sit to Stand (5TSTS) and left and right hand grip strength (HGS), cognition by Montreal Cognitive Assessment (MoCA) and Timed Up and Go test Cognition (TUG-cog), fall concern by Fall Efficacy Scale International (FES-I), exercise effort perception by Borg category ratio scale (Borg CR-10), and exercise contentment by a questionnaire.

Results

After exercise, PE significantly enhanced TUG and 5TSTS to a greater extent than VRE (TUG; p?=?0.004, 5TSTS; p?=?0.027) and BE (TUG; p?=?0,012, 5TSTS; p?<?0.001). VRE significantly improved MoCA (p?<?0.001) and FES-I (p?=?0.036) compared to PE, and 5TSTS (p?<?0.001) and FES-I (p?=?0.011) were improved relative to BE. MoCA was significantly enhanced by BE compared to PE (p?<?0.001) and both MoCA and TUG-cog were improved compared to VRE (p?=?0.04). PE and VRE significantly (p < 0.001) increased Borg CR-10 in all exercise sessions, whereas BE showed a significant improvement (p?< 0.001) in the first 4 sessions. Participants had a significantly greater satisfaction with BE than controls (p?=?0.006), and enjoyed VRE and BE more than PE (p?< 0.001). Subjects in all exercise groups exhibited benefits compared to the control group (p?< 0.001).

Conclusions

PE provided the best results in physical tests, VRE produced measurable improvements in physical and cognition scores, while BE enhanced cognition ability in older persons. Older persons preferred VRE and BE compared to PE. Both exercises are suggested to older persons to improve physical and cognitive conditions.

This systematic review summarizes the relatively scant literature concerning the effectiveness of water-based exercise (WBE) interventions in people with Parkinson’s disease (PD). Databases MEDLINE, EMBASE, PEDro, Scopus, and SportDiscus were searched from the earliest available date to December 2011. Studies had to meet the following selection criteria: (1) the target population was patients with PD; (2) the effects of a WBE intervention (as the primary intervention) were tested; (3) the abstract of the research was available in English. Selected studies were subject to unmasked quality assessment by applying a methodological scoring with a possible maximum score of 15 points. Twelve studies met the inclusion criteria, although only three of them achieved a methodological quality score above 10 points. Collectively, the data showed that WBE has some beneficial short-term effects on the impact that PD has on the patients (mainly on their motor symptoms and on their functional mobility), as well as on their quality of life. This review provides evidence that WBE is safe for patients with PD, but there is a lack of hard evidence regarding its beneficial effects. Further randomized and controlled trials with larger sample sizes are required.  相似文献

Background

This study evaluated the effects of a combined innovative training regime consisting of stochastic resonance whole-body vibration (SR-WBV) and a dance video game (DVG) on physical performance and muscle strength in long-term-care dwelling elderly.

Methods

Thirthy long-term-care elderly were randomly allocated to an intervention group (IG; n?=?16) receiving combined SR-WBV training and DVG, or a sham group (SG; n?=?14). IG performed five sets one minute of SR-WBV, with one minute rest between sets (base frequency 3 Hz up to 6 Hz, Noise 4) during the first five weeks on three days per week. From week five to eight a DVG was added to SR-WBV for IG on three days per week. SG performed a five-set SR-WBV program (1 Hz, Noise 1) lasting five times one minute, with one minute rest in between, three days a week. From week five to eight stepping exercises on a trampoline were added on three days per week. Primary outcome: Short physical performance battery (SPPB). Secondary outcome: isometric maximal voluntary contraction (IMVC), and sub phases of IMVC (Fsub), isometric rate of force development (IRFD) and sub time phases of IRFD (IRFDsub) were measured at baseline, after four and eight weeks. ANOVA with repeated measures was used for analyses of time and interaction effects and MANOVA determined between group intervention effects.

Results

Between group effects revealed significant effects on the SPPB primary outcome after four weeks F(1, 27)?=?6.17; p?=?0.02) and after eight weeks F(1,27)?=?11.8; p?=?0.002). Secondary muscle function related outcome showed significant between group effects in IG on IRFD, Fsub 30 ms, 100 ms, 200 ms and IRFDsub 0-30 ms, 0-50 ms, 0-100 ms and 100-200 ms compared to SG (all p?<?0.05).

Conclusions

Eight weeks SR-WBV and DVG intervention improved lower extremity physical function and muscle strength compared to a sham intervention in long-term-care elderly. SR-WBV and DVG seems to be effective as a training regime for skilling up in long-term-care elderly.

Background

Regular physical activity is a promising strategy to treat and prevent cognitive decline. The mechanisms that mediate these benefits are not fully clear but physical activity is thought to attenuate the harmful effects of chronic psychological stress and hypercortisolism on cognition. However, the circadian pattern of cortisol secretion is complex and it is not known which aspects are most closely associated with increased cognitive function and better physical performance. This is the first study to simultaneously measure cognitive function, the diurnal cycle of salivary cortisol and physical performance in older adults, without cognitive impairment (n?=?30) and with amnestic Mild Cognitive Impairment (aMCI) (n?=?30).

Results

Regression analysis showed that better cognitive function was associated with better physical performance. A greater variance in cortisol levels across the day from morning to evening was associated with better cognitive function and physical performance.

Conclusions

The results support the idea that a more dynamic cortisol secretion pattern is associated with better cognitive function and physical performance even in the presence of cognitive impairment, but our results could not confirm a mediating role in this relationship.

In a recent paper Amoruso et al. (2013) proposed a novel method for estimating population size of Feral Pigeons, the Superimposed Urban Strata (SUS) method. In our reply we firstly comment on the lack of a complete review of the available literature. Secondly we point out that the SUS method does not account for birds detection probability and thus it is just a simple index of abundance as many others proposed in recent years. Thirdly, we question the approach used by the authors to evaluate the reliability of their method. To conclude, we believe that the SUS method is not truly innovative and that further investigations are needed before considering it as a reliable way for estimating Feral Pigeons populations size.  相似文献

The relationship between HIV/AIDS and gay activism has been primarily informed by the American experience and understudied in nondemocratic contexts. Drawing upon qualitative research on China and Singapore, we refine understanding of HIV/AIDS’ influence on the development of gay activism under authoritarian conditions, by examining the processes through which activist organizations interact with laws and regulations, political norms, HIV/AIDS funding, and government responses to both HIV/AIDS and collective organizing. We show how HIV/AIDS’ influence plays out in multiple patterns, depending on the strategic responses that gay activists select from a constrained range of options to shape their organizations’ destinies. Therefore, we provide insights for development agencies and international donors into whether and how international assistance intended to encourage activism and wider social change are mediated by political and legal controls on local activism.  相似文献

This essay provides an overview of what the Committee on the Status of Race and Ethnic Minorities (CSREM) of the Pacific Sociological Association (PSA) has accomplished in the last couple of years. Through the implementation of Talking Circles and the Making Connection Program—a mentorship program, we were able to create a space that connects emerging sociologists of color to support networks within academia and beyond.  相似文献

This study examined concurrent and prospective associations of financial stress (financial strain, lack of financial access, public assistance) and parenting support factors (relationship quality, living at home, financial support) with young adults’ alcohol behaviors (alcohol use, heavy drinking, and problematic drinking) over a 5-year period. Analyses of National Longitudinal Study of Adolescent Health (Add Health) data (N = 7,159) showed that, over the study period, alcohol use and heavy drinking declined while problematic drinking increased. In addition, living at home and parental relationship quality were associated with fewer concurrent and prospective alcohol behaviors whereas financial strain and parents’ financial support were associated with more alcohol behaviors. The implications for minimizing alcohol misuse in young adults amid uncertain economic conditions are discussed.  相似文献

The purpose of this study was to evaluate the quality (item difficulty and discriminability, construct validity, and reliability) of a financial literacy test that has been used to measure financial literacy in multiple countries. The test was analyzed based on Classical Test Theory and Item Response Theory, specifically the Rasch model, with the goal of identifying areas of improvement. The findings from the two measurement frameworks were quite comparable and identified similar measurement problems. Steps to improve the financial literacy measure were recommended.  相似文献

Growing human populations make it imperative for ecologists to identify strategies to conserve biodiversity in human-dominated landscapes, such as cities. Effects of urbanization on birds are particularly well-studied, but questions remain regarding the best conservation approaches. Debate about the relative utility of focusing conservation efforts on nature reserves versus developed lands has focused largely on comparing species abundance or presence, with few studies addressing underlying behavioral or demographic mechanisms. Here we evaluated differences in avian reproductive success in nature reserves and matrix habitats to test the assumption that nest predation is lower within areas protected from development. Specifically, we investigated 1) whether nest survival differed in replicated pairs of forest parks and residential neighborhoods and 2) whether differences in nest survival were associated with changes in which species most frequently depredated nests. From April–August 2007–2014, we monitored nests of two native birds, American robin (Turdus migratorius) and northern cardinal (Cardinalis cardinalis), and video-documented nest predators in paired forest-matrix habitats in the Columbus, Ohio metropolitan area. We found similar rates of nest survival in the two habitats for both robins (Χ21?=?0.715, p?=?0.398, n?=?741 nests) and cardinals (Χ21?=?0.926, p?=?0.336, n?=?1156 nests), but interactions between predators and prey differed. In particular, domestic cats (Felis catus) were over five times as likely to depredate cardinal nests in matrix habitats versus forest parks (Χ21?=?7.24, simulated p?=?0.010; nforest?=?3, nmatrix?=?7). Our results suggest that at least in some circumstances, nest success of native birds may be equivalent between nature reserves and adjacent residential matrix habitats, and thus residential neighborhoods may contribute positively to bird conservation in urban landscapes.  相似文献

The objectives of this paper are to map strategies for resource mobilization of nongovernmental organizations (NGOs) in different sectors in heavily aid-dependent Cambodia and analyse the past and future trends of each of the evolving strategies. The data used is the product of a national survey revealing NGOs’ key funding sources and trends in a 10-year period from 2006 to 2016. Foreign grants and donations are still dominant, but one out of five NGOs surveyed engage in earned-income activities, and this trend is expected to increase in the next 5 years. This study contributes to the on-going academic and development debate about the struggles non-profit organizations face and the ensuing strategies for mobilizing funding. It also raises questions about the potential effects of different strategies for resource mobilization, social and ethical dilemmas, and the trade-off between different choices of funding resulting in a diversification strategy.  相似文献

This mixed-methods study examines the relationship between adolescent identity complexity (Clin Social Work J 21(1):11–24 1991) and youth purpose related to participation in a wilderness experience program at an alternative, residential boarding school in Colorado. Students in this study (N = 55) completed an adapted version of the Self-Worth Index (Ment Health Relig Cult 4(2):103–108 2001) before and after participation in a wilderness experience program. Youth in the study also completed a pre- and post-test eight-item index measuring identity complexity, with each item assessed on a five-point Likert scale. Likewise, qualitative, face-to-face interviews with each student were conducted to triangulate findings and further explore the impact of the wilderness program on identity complexity and youth purpose for youth labeled “high risk.” Data analysis revealed that the wilderness program contributed to students’ positive sense of identity and purpose in their lives, and helped them transition into the residential school culture successfully.  相似文献

This essay reflects upon the author’s Pacific Sociological Association (PSA)-related experiences with regards to the scholarship of teaching and learning over the past 28 years. Labeling this time period the “Golden Age of Scholarship on Teaching and learning,” the author proposes that the PSA has promoted and encouraged scholarship in this area in three ways: 1) by providing access to best practices, 2) by facilitating members networking with scholars who share similar interests, and 3) by exposing graduate students to best practices of teaching and learning. The author then supports this contention with examples of the increase in the number of sessions at the annual PSA meetings on both Service-Learning and On-Line Teaching during this time period. The author concludes this essay by noting how his research on supporting first-generation college students greatly benefited from PSA-facilitated networking with other scholars working in this area.  相似文献

Problem gambling rates in older adults have risen dramatically in recent years and require further investigation. Limited available research has suggested that social needs may motivate gambling and hence problem gambling in older adults. Un-partnered older adults may be at greater risk of problem gambling than those with a partner. The current study explored whether loneliness mediated the marital status–problem gambling relationship, and whether gender moderated the mediation model. It was hypothesised that the relationship between being un-partnered and higher levels of loneliness would be stronger for older men than older women. A community sample of Australian men (n = 92) and women (n = 91) gamblers aged from 60 to 90 years (M = 69.75, SD = 7.28) completed the UCLA Loneliness Scale and the Problem Gambling Severity Index. The results supported the moderated mediation model, with loneliness mediating the relationship between marital status and problem gambling for older men but not for older women. It appears that felt loneliness is an important predictor of problem gambling in older adults, and that meeting the social and emotional needs of un-partnered men is important.  相似文献

Although nongovernmental organizations (NGOs) in post-socialist countries have been under a microscope since their inception, their relations with the state are only beginning to come into focus and to be the subject of comparative and theoretical assessment. What these relationships mean to different stakeholders, whether they take trajectories similar to those in the West, and how they will be shaped by socialist legacies, are important questions to address before such relations are naturalized as “the way things are.” This paper examines NGO/state relations in the development of health care and disability services in Croatia, a nation newly admitted to membership in the European Union. The paper explores policy and institutional legacies, health care privatization, and relations with health professionals as forces affecting the financing, structure, and experience of relationships between NGOs and the post-socialist state.  相似文献

The aims of this study were to examine the associations between psychiatric disorders and pathological gambling (PG) and the clustering of psychiatric disorders in high risk gambler populations. The sample comprised 140 regular gamblers who were recruited from the general public. A variety of self- report and semi structured questionnaires was administered, including the Mini International Neuropsychiatric Interview, The Personality Diagnostic Questionnaire-4th Edition, NORC DSM-IV Screen for Gambling Problems Self- administered and Problem Gambling Severity Index. Axis I and Axis II psychiatric disorders and personality disturbances were found to be more prevalent amongst pathological gamblers than other gamblers with the strongest differences observed for mood and anxiety-related disorders. Almost two-thirds of pathological gamblers reported both an anxiety or mood disorder in conjunction with another type of disorder. These differences between the gambling groups existed even after controlling for gender. The results highlight the high rates of co-morbidity in pathological gamblers in the community and the extent to which anxiety and mood disorders co-existing with other forms of pathology. These results highlight the significant challenges facing treatment services in the treatment of PG and the extent to which this should be treated as the primary disorder.  相似文献
