Effects of physical,virtual reality-based,and brain exercise on physical,cognition, and preference in older persons: a randomized controlled trial

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.

     

Tracking of sport and exercise types from midlife to old age: a 20-year cohort study of British men

Background

Previous physical activity (PA) tracking studies have examined the stability of overall PA and/or PA types, but few have investigated how specific types of sport/exercise track over the life course. The aim of this study was to determine how specific sports/exercises in midlife track and predict future sport/exercise and PA in men transitioning to old age.

Methods

Seven thousand seven hundred thirty-five men (aged 40–59?years) recruited in 1978–80 were followed up after 12, 16 and 20?years. At each wave men self-reported participation in sport/exercise. Frequent sport/exercise participants (>?1/month) reported the types of sport/exercise they engaged in. Men also reported total PA, health status, lifestyle behaviours and socio-demographic characteristics. Stability of each sport/exercise was assessed using kappa statistics and intraclass correlation coefficients. Logistic regression estimated the odds of participating in sport/exercise and being active at 20-year follow up according to specific types of sport/exercise in midlife.

Results

Three thousand three hundred eighty-four men with complete data at all waves were included in analyses. Tracking of specific sports/exercises ranged from fair to substantial, with golf being the most common and most stable. Bowls was the most frequently adopted. Odds of participating in sport/exercise and being active in old age varied according to sport/exercise types in midlife. Golf and bowls in midlife were the strongest predictors of sport/exercise participation in old age. Golf, cricket and running/jogging in midlife were among the strongest predictors of being active in old age. Compared to participating in just one sport/exercise in midlife, sampling multiple sports/exercises was more strongly associated with sport/exercise participation and being active in old age.

Conclusion

The stability of sport/exercise participation from midlife to old age varies by type. Specific sports/exercises in midlife may be more likely to predict future PA than others. However, participating in a range of sports/exercises may be optimal for preserving PA into old age.

     

Influence of socioeconomic status on changes in body size and physical activity in ageing black South African women

Background

The increasing prevalence of obesity in sub-Saharan African women is not well understood, and black South African women in the region are particularly vulnerable. This study aimed to examine whether the relationship of socioeconomic status (SES) with changes in body mass index (BMI) and waist circumference (WC) is mediated by physical activity in ageing African women.

Methods

In a longitudinal analysis of the 518 caregivers associated with the Birth to Twenty Plus study, the role of SES associated with 10-year changes in BMI and WC was tested using structural equation modelling (SEM). The degree of mediation of moderate-vigorous physical activity (MVPA) and sitting time in this association was also assessed.

Results

The prevalence of obesity increased significantly from baseline to follow-up (p?<?0.0001). In the SEM models, baseline SES had a direct positive effect on changes in BMI (β, 95% CI, 0.02 (0.005 to 0.04), and a direct negative effect on changes in MVPA (β, 95% CI, ??3.81 (??6.92 to ??0.70). Baseline MVPA had a direct negative effect (β, 95% CI, ??0.002 (??0.003 to ??0.0003) and indirect positive effect via change in MVPA (β, 95% CI, 0.01 (0.0001 to 0.001) on change in WC.

Conclusions

Our study demonstrates the role and interaction of sociodemographic and behavioural predictors of obesity, and suggests a multifaceted approach to management of the crisis in communities of ageing urban African women.

     

Relationships between muscle strength and multi-channel surface EMG parameters in eighty-eight elderly

Background

Since age-related muscle strength loss cannot be explained solely by muscle atrophy, other determinants would also contribute to muscle strength in elderly. The present study aimed to clarify contribution of neuromuscular activation pattern to muscle strength in elderly group. From 88 elderlies (age: 61~?83 years), multi-channel surface electromyography (EMG) of the vastus lateralis muscle was recorded with two-dimensional 64 electrodes during isometric submaximal ramp-up knee extension to assess neuromuscular activation pattern. Correlation analysis and stepwise regression analysis were performed between muscle strength and the parameters for signal amplitude and spatial distribution pattern, i.e., root mean square (RMS), correlation coefficient, and modified entropy of multi-channel surface EMG.

Results

There was a significant correlation between muscle strength and RMS (r =?0.361, p =?0.001) in the elderly. Muscle thickness (r =?0.519, p <?0.001), RMS (r =?0.288, p?=?0.001), and normalized RMS (r =?0.177, p =?0.047) were selected as major determinants of muscle strength in stepwise regression analysis (r?=?0.664 in the selected model).

Conclusion

These results suggest that inter-individual difference in muscle strength in elderly can be partly explained by surface EMG amplitude. We concluded that neuromuscular activation pattern is also major determinants of muscle strength on elderly in addition to indicator of muscle volume.

     

The Role of <Emphasis Type="Italic">New Zealand Sociology</Emphasis> in Developing New Zealand Sociology

Journals may set themselves one or several of a range of missions, but often a national Sociology Association’s journal is concerned to be a vehicle assisting in the shaping of that country’s ‘national sociology’, while maintaining some openness to international sociology. This personalised case study of New Zealand’s sociology journal discusses the extent to which this mission has been achieved over the last decade and more generally over the journal’s history, and the nitty-gritty of challenges and operational issues involved in carrying this out.     

Experiences,Burdens, and Support Needs in Siblings of Girls and Women with Anorexia Nervosa: Results from a Qualitative Interview Study

For many years, siblings of women and girls suffering from anorexia have been regarded as “the forgotten kin,” as they have been overlooked by both researchers and clinicians. Therefore, the goal of this explorative study was to investigate siblings’ experiences, burdens, and support needs in a differentiated manner. Siblings (n = 16) of patients with an ICD-10 diagnosis “anorexia nervosa” (F 50.0) took part in a qualitative, in-depth interview study; the data were assessed using content analysis. The results of this study should be especially interesting for clinical social work. Using the findings, a variety of concrete recommendations for psycho-social practice can be made, for example regarding the inclusion of siblings in treatment settings, as well as specific support concepts for siblings of anorexic women and girls in different age groups.     

The Effects of Merit-Based Scholarships on Educational Outcomes

This paper analyzes the effect of a statewide merit-based scholarship program on educational outcomes in Arizona. It tests whether Arizona’s Instrument to Measure Standards (AIMS) scholarship has an effect on a comprehensive set of educational outcomes such as the number of applicants, student admissions, first-year first-time enrollment, ACT scores of entering freshman, retention rates, as well as on the level of tuition and fees at the three schools targeted by the program; Arizona State University, University of Arizona and Northern Arizona University. Both difference-in-differences estimation as well as synthetic control methods shows that AIMS has an economically and statistically significant effect enrollment. Enrollment effects are greatest among African American and Hispanic students and are significant for both men and women. While point estimates suggest that AIMS also lead to increases in tuition and fees, these results are not robust to placebo tests.     

Remittances as an Insurance Mechanism in the Labor Market

The probability that Mexican households receive remittances increases in response to temporary loss of employment by household heads. Evidence indicates that the probability doubles in the short-term, with a stronger effect in the first quarter of unemployment. Taking into account inter-household transfers within Mexico, the increase in the probability of private transfers is similar in households with low and high access to migratory networks in the U. S. The effectiveness of private transfers as an insurance mechanism has been reduced in an environment of economic crisis.     

Judging Facial Emotion Expressions in Context: The Influence of Culture and Self-Construal Orientation

We assessed the impact of social context on the judgment of emotional facial expressions as a function of self-construal and decoding rules. German and Greek participants rated spontaneous emotional faces shown either alone or surrounded by other faces with congruent or incongruent facial expressions. Greek participants were higher in interdependence than German participants. In line with cultural decoding rules, Greek participants rated anger expressions less intensely and sad and disgust expressions more intensely. Social context affected the ratings by both groups in different ways. In the more interdependent culture (Greece) participants perceived anger least intensely when the group showed neutral expressions, whereas sadness expressions were rated as most intense in the absence of social context. In the independent culture (Germany) a group context (others expressing anger or happiness) additionally amplified the perception of angry and happy expressions. In line with the notion that these effects are mediated by more holistic processing linked to higher interdependence, this difference disappeared when we controlled for interdependence on the individual level. The findings confirm the usefulness of considering both country level and individual level factors when studying cultural differences.
