Examining the role of parental self-regulation in family physical activity: A mixed-methods approach

Physical activity (PA) is essential for good health. However, parents risk becoming less active because of the demands of parenting. This has consequences for children as parents are role models. The present study used a mixed-methods approach to explore parental self-regulation associated with PA. Data were collected from 36 parents with preschool-aged children. They were interviewed about their PA and their family’s PA. Parents also completed PA and self-regulation questionnaires and wore an accelerometer for five days. Qualitative data were examined using an inductive approach to thematic analysis. It showed that parents felt that they had limited time for personal PA. Mothers’ self-regulation was driven by an ethic of care and subjective norms, whereas fathers’ self-regulation was driven by beliefs about the importance of autonomy. Nevertheless, both parents saw caring for their children as the main priority. Quantitative data were examined using multiple regression analyses. Results showed that different self-regulatory behaviours predicted the PA of mothers and fathers. Which predictors were significant depended on the type of activity and how it was measured. The findings warrant longitudinal research that would enable the effect of family dynamics on self-regulation associated with PA to be assessed.     

Effects of a physical exercise session on state body image: The influence of pre-experimental body dissatisfaction and concerns about weight and shape

The effects of a physical exercise session on state body image and mood were examined. In a cross-over design, participants were randomised to two groups starting either with physical exercise (PE; experimental condition) or with reading a newspaper (RN; control condition). Before and after PE and RN, participants (N = 65) rated their body dimensions using a digital photo distortion technique and indicated their attitudinal body image and mood. Participants’ judgements of their ‘felt’ body dimensions and attitudes toward their own body were affected differently by PE and RN, indicating that participants felt slightly slimmer and were more satisfied with their bodies after PE. Exercise-induced changes in body perception were greater, the higher the pre-experimental drive for thinness, body dissatisfaction and weight/shape concerns were. Especially in those participants with higher body image disturbances, physical exercise can have a reinforcing effect on immediate body image and mood improvement.     

Controlled trial of a minimal-intervention exercise program for middle-aged working women

Abstract

Despite potential for major benefits, middle-aged women have low levels of aerobic exercise. A 12-week minimal-intervention exercise program was evaluated with female university employees aged 40 to 61. Following pre-testing, participants were randomly assigned to exercise or wait-list control. Testing was repeated at 12, 24 and 48 weeks. Exercisers improved significantly in aerobic fitness at 12 and 24 weeks, both groups decreased resting arterial pnssurc and body composition measures, and improved in exercise knowledge. Effects, however, were not well maintained at 48 weeks. These results are comparable to those obtained fmm intensive interventions and, while modest, suggest that a threshold has been reached for the modification of physiological control systems which are important for reducing cardiovascular disease risk. Middle-aged women face major social and practical baniers to regular exercise, and the minimal-intervention approach allows for a combination of flexibility and structure which seems appropriate for this group.     

Affective and health-related outcome expectancies for physical activity in older adults

This study tests the effects of affective and health-related outcome expectancies on physical exercise, assuming stronger direct and indirect (via intention) effects from affective outcome expectancy to physical exercise than from health-related outcome expectancy to exercise. Physical exercise and social cognitive variables were assessed at baseline, and 6- and 12-month follow-up in 335 older adults (60–95 years of age). Applying structural equation modelling, there was a direct effect from affective, but not from health-related outcome expectancy on intentions and behaviour. Also, the indirect effect from self-efficacy on physical exercise via affective outcome expectancy was significant, whereas the mediation via health-related outcome expectancy was not. These findings emphasise the relative importance of affective versus health-related outcome expectancies in predicting intentions and physical exercise in older adults and highlight the importance to separate these facets at a conceptual level to enhance both theory development and health promotion.     

Interest in Hosting an Exercise Program for Older Adults at African-American Churches

ABSTRACT

The primary objective of this research was to evaluate which type of African-American churches may be good sites for launching an exercise program for older adults. A survey of ministers at 42 African-American churches was conducted. Churches interested in (1) hosting an exercise program for older adults and (2) identifying church members who would take a leadership role in recruitment, are those that are more resourceful in terms of large membership, adequate space, and higher socioeconomic status. Additional ideas are offered on interviewing African-American ministers, and identifying churches interested in reaching out to less resourceful neighboring churches.     

Neuropsychological and neurophysiological effects of strengthening exercise for early dementia: A pilot study

ABSTRACT

Research demonstrates a positive effect of aerobic exercise on cognitive functioning in older adults. Unfortunately, aerobic exercise is often contraindicated for older adults due to cardiovascular and functional limitations. Low-intensity strengthening exercise may offer a practical alternative, but the neuropsychological benefits and potential neurophysiological mechanisms are less well understood. The current study evaluated the effects of a 10-week strengthening exercise intervention on cognitive functioning and EEG in a sample of 13 older adults with early dementia, and 9 normative controls. Results revealed beneficial effects of strengthening exercise on verbal memory coupled with frontal beta and delta power asymmetries and N200 amplitude asymmetry. Results point to increased cognitive efficiency following 10 weeks of strengthening exercise. The findings suggest it is feasible to conduct a strengthening intervention with early dementia patients, and to gather neuropsychological and neurophysiological data to evaluate outcomes. Strengthening exercise may serve as a useful alternative to aerobic exercise.     

Effects of a self-regulation intervention on exercise are moderated by depressive symptoms: A quasi-experimental study

This study investigated whether a computer-based self-regulation intervention increases physical exercise in individuals with or without depressive symptoms. A total of 361 individuals in orthopedic rehabilitation, 36 of them with depressive symptoms, were recruited in Germany. In a quasi-experimental study, individuals were allocated to either a computer-based self-regulation intervention or an online questionnaire. Exercise was measured at the beginning of rehabilitation and six weeks after rehabilitation. Depressive symptoms were assessed at the end of rehabilitation. An analysis of covariance was conducted, controlling for exercise baseline, sex, and phase of assessment. A main effect for depressive symptoms (p = .005) and intervention group (p = .011), as well as a marginal interaction of intervention x depressive symptoms were found (p = .076). Results indicate that the self-regulation exercise intervention in an orthopedic rehabilitation setting seem to be only effective in non-depressed individuals. Future research should examine how health behavior change programs can be designed more effectively for individuals with depressive symptoms.     

Feasibility,acceptability, and impact of a web-based gratitude exercise among individuals in outpatient treatment for alcohol use disorder

This mixed methods pilot study examined the feasibility, acceptability, and impact of a web-based gratitude exercise (the ‘Three Good Things’ exercise (TGT)) among 23 adults in outpatient treatment for alcohol use disorder. Participants were randomized to TGT or a placebo condition. The intervention was feasible with high rates of completion. Participants found TGT acceptable and welcomed the structure of daily e-mails; however, they found it difficult at times and discontinued TGT when the study ended. Participants associated TGT with gratitude, although there were no observed changes in grateful disposition over time. TGT had a significant effect on decreasing negative affect and increasing unactivated (e.g. feeling calm, at ease) positive affect, although there were no differences between groups at the 8 week follow-up. Qualitative results converged on quantitative findings that TGT was convenient, feasible, and acceptable and additionally suggested that TGT was beneficial for engendering positive cognitions and reinforcing recovery.     

“善良意志”与道德权限

“善良意志”是康德伦理学的核心概念,他将善良意志提升到道德领域的至善地位,从而确定了道德的纯粹性。他还借助善良意志划分了善与恶的界限,指明了责任作为检验善恶的标准,将传统德性论的品质和功用主义的幸福都排除在道德领域之外。由此,康德还将伦理与道德的界限做了区分,他强调伦理与道德各自明确自身的权责,从而充分发挥各自的作用。     

Quadrupedal movement training improves markers of cognition and joint repositioning

IntroductionExercise, and in particular balance and coordination related activities such as dance, appear to have positive effects on cognitive function, as well as neurodegenerative conditions such as dementia and Parkinson’s disease. Quadrupedal gait training is a movement system requiring coordination of all four limbs that has previously been associated with cognitive development in children. There is currently little research into the effect of complex QDP movements on cognitive function in adults.PurposeTo determine the effects of a novel four-week quadrupedal gait training programme on markers of cognitive function and joint reposition sense in healthy adults.MethodsTwenty-two physically active sports science students (15 male and 7 female) were divided into two groups: a training group (TG) and a control group (CG). All participants completed the Wisconsin Card Sorting Task (WCST) and were tested for joint reposition sense before and after a four-week intervention, during which time the TG completed a series of progressive and challenging quadrupedal movement training sessions.ResultsParticipants in the TG showed significant improvements in the WCST, with improvements in perseverative errors, non-perseverative errors, and conceptual level response. This improvement was not found in the CG. Joint reposition sense also improved for the TG, but only at 20 degrees of shoulder flexion.ConclusionsPerformance of a novel, progressive, and challenging task, requiring the coordination of all 4 limbs, has a beneficial impact on cognitive flexibility, and in joint reposition sense, although only at the specific joint angle directly targeted by the training. The findings are consistent with other studies showing improvements in executive function and joint reposition sense following physical activity.
