Psychosocial, behavioral, and biometric characteristics of stages of exercise adoption

This study incorporates the Stages of Change model to examine the relationship between the stages of exercise adoption and indicators of health and fitness. Subjects were 198 United States Forest Service (USFS) workers recruited from 8 USFS ranger stations in the Pacific Northwest. Analysis indicated that those subjects in Action and Maintenance stages of exercise adoption differed significantly from those in Preparation and Precontemplation/Contemplation stages on a variety of indicators of both health and fitness. Also, interesting differences were noted among the physically inactive stages, e.g., Preparation stage subjects showed lower triglycerides, systolic blood pressure, and higher HDL cholesterol compared with subjects in the Precontemplation/Contemplation stage. Progressing to the Preparation stage, where the individual remains inactive but is aware of the problem and has begun to make small changes, is associated with a differing (more positive) health profile in this study compared to those in the Precontemplation/Contemplation stage. These results imply that simply advancing in stage can have a variety of health benefits.     

Staying fit and staying well: physical fitness as a moderator of life stress

Previous research suggests that physical fitness moderates the adverse effects of stressful life events. However, a reliance on self-reports of fitness and health may limit the validity of prior investigations. The present research tested the stress-buffering effect of fitness with subjective and objective indicators of exercise, fitness, and physical well-being. For self-reports of health, both self-reports of exercise and objective measures of fitness showed the buffering effect; however, only objective fitness levels buffered stress when visits to a health facility were considered. Additional evidence indicated that this effect was largely independent of measures of psychological distress. Implications for understanding the link between fitness, stress, and health status are discussed.     

Does Work-Home Interference mediate the relationship between workload and well-being?

Drawing on the Effort-Recovery (E-R) model, the current study investigated to what extent Work-Home Interference (WHI) mediated the relationship between workload and two indicators of well-being, that is, (a) affective well-being (i.e., work-related negative affect and depressive mood) and (b) subjective health (i.e., health complaints). In Part I of this study, Structural Equation Modeling (SEM) was used to test several competing models of mediation—full, partial, or no mediation—in three homogeneous samples (166 medical residents, 194 child care workers, and 224 bus drivers). In Part II of this study, we cross-validated the best fitting model in an independent heterogeneous sample (1421 Dutch workers). The results provided support for the E-R model in that WHI played a significant role in mediating the impact of workload on workers’ well-being. WHI fully mediated the relationship of workload with depressive mood and health complaints, and partially mediated the relationship with work-related negative affect. This differential role of WHI indicates that WHI might play a more crucial mediating role with respect to general (context-free) indicators of well-being than with respect to work-related indicators of well-being. In general, the findings of the current study suggest that workload exerts its negative effects on well-being (at least partly) through a process of spillover of negative load-effects that impede recovery during the non-working hours.     

Leisure and Its Role as a Strategy for Coping with Work Stress

The purpose of this study was to determine the dimensions of leisure that were important to people coping with work-related stress. Data were provided by 695 principals and deputy principals from secondary schools throughout New Zealand who were experiencing major legislative and organizational change in the education sector. The results produced a robust, replicable, and reliable two-factor structure using FACTOREP, a factor replication procedure. It appears that leisure is best measured in terms of active-challenge and passive-recuperative dimensions when considered in relation to coping with work-related stress. The results show that for the present occupational group, the passive nature of leisure is more important for coping with work stress. These results have implications for those involved in workplace health promotion where the emphasis thus far has been on physical activity and fitness. The results also confirm the importance of determining the most appropriate number of factors to rotate.     

工作特征对工作者的影响——要求-控制模型与工作要求-资源模型的比较

工作特征是指与工作相关的因素或属性, 它对工作者的身心健康有重要影响。通过对比研究发现, 虽然要求-控制模型(Demand-Control Model, 简称DC模型)将工作特征分为相对具体的工作要求、工作控制和社会支持, 工作要求-资源模型(Job Demands-Resources Model, 简称JD-R模型)则将工作特征划分为更为概括的工作要求和工作资源两个维度, 但是它们关注的结果变量都包含个体身心健康和组织工作绩效, 都强调了工作特征对工作者的影响。在今后的研究中, 应深入探讨不同职业中起关键作用的工作特征和不同资源与要求组合的作用, 进一步研究工作特征模型对不同特点个体和我国民众群体的适用性, 并尝试将研究成果应用于工作再设计的实践, 以促进工作者的职业健康。     

Evaluation of physical activity measured via accelerometry in rural fourth-grade children

Interest in the benefits of exercise has prompted increased research examining the relationship between physical activity and health status in adults. More recently, considerable research effort has been directed toward the role of physical activity in young children as a precursor to adult physical fitness. The purpose of this study was to estimate the relationship between physical activity measured via accelerometry and body mass index, body mass, body composition, and physical fitness in fourth-grade boys and girls during physical education lessons. 54 fourth-grade students in rural Pennsylvania (28 girls, M age 9.6, SD = .56; 26 boys, M age 9.5, SD = .51) were subjects. Girls were significantly less active during all lessons measured (p < .001). The results of linear regression analyses indicated that physical activity was negatively associated with body mass index, body mass, and body fat percentage (p < .05), and positively associated with physical fitness (VO2max) (p < .01). These data indicate the need for curricular intervention to motivate girls to increase their activity during structured physical education lessons and demonstrate the efficacy of the body mass index as a screening tool within the schools.     

Personality correlates of physical fitness

In this article, I examine the relation between personality and physical fitness. One group (N = 97) of male adults completed the Hogan Personality Inventory and five nationally recognized physical fitness batteries. A second group (N = 35) completed the Minnesota Multiphasic Personality Inventory and a set of medical and physical performance assessments. Results indicate that physical fitness must be defined in multidimensional terms and that fitness is related to self-confidence and self-discipline. Measures of psychopathology were unrelated to measures of health and fitness. These data suggest that the personal qualities associated with fitness are also those that promote and extend health.     

Physical health correlates of overprediction of physical discomfort during exercise

This study sought to determine if overprediction of physical discomfort prior to and following exercise was related to a number of self-report and objective measures of physical health status in a general population sample. Cross-sectional findings indicated a significant and specific relation between patterns of discomfort overprediction (vs under- or accurate prediction) and negative self-reported health status and attitudes to exercise, lower levels of physical activity, as well as poorer scores for resting heart rate, cardiorespiratory fitness and body mass index (but not waist:hip ratio). Females were more likely to overpredict discomfort, were less active and had poorer physical health than males. The potential usefulness of the prediction match-mismatch paradigm for studying exercise-related appraisal processes as proximal determinants of physical activity are discussed. Information obtained from such studies could prove useful in public health education campaigns aimed at increasing levels of physical activity in the general population, particularly among the less active.     

Perceived Fitness Predicts Daily Coping Better Than Physical Activity or Aerobic Fitness

This study sought to evaluate the association between perceived physical fitness, actual fitness measured by VO₂max, daily physical activity measured by an ambulatory activity monitor, and coping with daily stress. One hundred and thirty participants completed a series of questionnaires measuring perceived fitness as well as daily stress and coping levels each day for one week. Participants were also provided with a digital physical activity monitor (Yamax Digi-Walker SW 200) and instructed to wear it throughout the seven day assessment period. Upon completion of the week evaluation, participants then were evaluated for actual physical fitness by treadmill testing. Multiple regression and effect size analysis revealed that perceived fitness predicted daily coping better than actual fitness and daily physical activity. Coping was unrelated to age, gender,VO₂max, and physical activity. Results suggest that perceived fitness may be a better predictor of coping with daily stress than actual physical fitness or physical activity.     

The interplay of actual and perceived physical fitness in children: Effects on motivation and physical activity

From a sport and exercise psychology perspective, both the actual and perceived physical fitness become important for motivation towards physical activity and persistent physical activity in children no later than middle childhood (Stodden et al., 2008). To date, the effects of actual and perceived physical fitness have been investigated from a variable-centered approach (Jekauc et al., 2017). However, within this approach, the accuracy of the perceived physical fitness remains unconsidered. As actual and perceived physical fitness levels can be divergent, especially in children due to greater egocentricity and hence less comparison processes (Harter, 2006), also the accuracy of perceived physical fitness should be considered.In total, 462 children from 3rd and, approximately nine months later, from 4th grade participated in this study (M_age = 8.79 years). Third-grade students were assessed on their actual physical fitness, perceived physical fitness, and physical activity. In fourth grade, students were asked to fill out questionnaires that assess motivational regulations and physical activity. Polynomial regressions with response surface analyses were conducted to analyze main effects and accuracy effects of actual and perceived physical fitness on motivation and physical activity. Analyses revealed that children with higher actual and perceived physical fitness levels show greater autonomous motivation, higher current physical activity levels and higher physical activity levels nine months later. In addition, children who perceive their physical fitness more accurately show more current physical activity. Results indicate that the interplay between actual and perceived physical fitness does not only have an effect on physical activity but also on autonomous motivation, which is a predictor for long-term physical activity. Therefore, intervention should focus on the promotion of actual and perceived physical fitness. In addition, the ability to accurately assess fitness should be promoted in this age group.     

Stages of change for health-related behaviours in 18 year-old Australians

Abstract This study investigated the validity of a Stages of Change algorithm with respect to independent measures of physical activity and fitness. dietary intake and alcohol consumption in 18 year-old Ausmlian men (n = 301) and women (n = 282). Stage of Change categories were related to fat and fibre intakes in men and fibre intake in women as well as hit and vegetable intakes in men and women. Physical activity and fitness for men and women also showed significant linear associations with Stage of Change categories. Alcohol consumption was significantly associated with Stage of Change categories for men but not for women although recorded alcohol consumption was very variable for women. However, the algorithm was valid for both men and women when drinking alcohol consistent with national guidelines on safe drinking was used. In summary, with reference to actual health behaviours, the Stages of Change algorithm was valid for young men and women for diet. physical activity and alcohol drinking. Independent behavioural data were not available for smoking behaviours. Using the algorithm, there were significant associations in men between prccontemplation status for diet and drinking and diet and physical activity, in women between diet and smoking and in both men and women between drinking and smoking. Covariance between precontemplation status for different health behaviours therefore suggests the need for multimodal interventions.     

Physical fitness, body image, and locus of control in college women dancers and nondancers

This study assessed the correlations among measures of physical fitness, body image and locus of control in college freshman women dancers and nondancers. 39 students enrolled in courses in modern, ballet, and jazz dance, and 120 students enrolled in an introductory personal health course were administered the Hall Physical Fitness Test Profile, the Winstead and Cash 54-item short-form Body Self-relations Questionnaire (BSRQ), and the Adult Nowicki-Strickland Locus of Control Scale. Analysis showed dancers were more physically fit, scored more positively on the BSRQ physical fitness and health domains, and were more internal in their locus of control than the nondancers. There was no significant difference between dancers and nondancers on the BSRQ appearance domain. The significant positive correlation between BSRQ health and physical fitness among dancers was not observed among nondancers. The significant positive correlation for BSRQ appearance and health was noted for nondancers but not for dancers.     

A data-matching study of the role of fatigue in work-related crashes

This study investigated fatigue involvement in work and nonwork-related road traffic casualty crashes using a dataset formed by linking the New South Wales workers compensation dataset with the New South Wales road traffic crash database. In many crash databases work-relatedness cannot be identified. Other databases, such as workers compensation data provide information on work-related road traffic injury but little on the circumstances of the crash. Probabilistic linkage overcame these problems by matching cases from the workers compensation data to the crash data to produce a new dataset of work-related road traffic casualties. The patterns of fatigue-involvement in these casualty crashes showed similarities between work-related crashes and nonwork-related crashes. Fatigue-involved crashes were more likely to result in fatality, involved higher costs, were more likely to involve heavy and light trucks and to involve illegal alcohol or speeding no matter whether they were work-related or not. Time of crash was the only characteristic that differed between work and nonwork-related crashes. Work-related fatigue-involved crashes tended to occur around dawn whereas work-related non-fatigue crashes occurred in peak hour traffic. Timing of work-related crashes involving fatigue varied little across the 24-h period whereas those not involving fatigue showed an afternoon peak only. While fatigue-related crashes occur in similar ways regardless of work status, strategies for work-related driver fatigue should not be left to be addressed only by general road safety strategies. As there is more control in the workplace over some of the fundamental causes of driver fatigue work-related fatigue management strategies are much more likely to be successful.     

Achievement Goals,Physical Self‐Concept,and Social Physique Anxiety in a Physical Activity Context1

Three studies tested relations between self‐related constructs and approach and avoidance achievement goals in a health‐related physical activity context. Physical self‐concept was hypothesized to be positively related, and social physique anxiety to be negatively related, to approach goals in physical activity. Achievement goals were also expected to mediate relations between the self‐related constructs and behavior. Structural equation models supported the hypothesized pattern of effects in a physical activity context (Study 1). The model for physical activity was invariant across collectivistic and individualistic cultures (Study 2). Relations between physical self‐concept, social physique anxiety, and achievement goals were stronger among regular gym and fitness center users than among nonusers (Study 3). The findings are discussed in relation to achievement goal theory.     

Obesity, cardiovascular fitness, and physically active adolescents’ motivations for activity: A self-determination theory approach

Objectives

Overweight and obesity pose significant health problems for adolescents. Rates of overweight and obesity in children have increased 45% in the last decade and have increased three-fold since 1980. Because children who are physically active are at lower risk for the development of obesity, it is important to understand some of the factors that influence children’s physical activity patterns. The purpose of this study was to examine the relationship between motivation, cardiorespiratory fitness, and weight status, defined as obese or non-obese. We predicted that the association between motivation and weight status would become non-significant when controlling for cardiorespiratory fitness.

Design

The study employed a correlational, cross-sectional design.

Method

Participants included physically active middle school students (N = 82. 51% female) of aged 12–14 years, who participated in the Teen Eating and Activity Mentoring in Schools (TEAMS) study aimed at improving health and preventing obesity among middle school students. Students completed attitudinal questionnaires about physical activity and self-determination on a computer-based system and participated in a number of fitness performance, health behavior, and anthropometric assessments.

Results

Non-obese adolescents showed higher intrinsic motivation scores than obese adolescents. Mediational analyses showed that cardiorespiratory fitness mediated the relationship between motivation and weight status.

Conclusions

The results of this study demonstrate differences in physical activity motivation as a function of adolescent weight status, but only for intrinsic motivation. As predicted, adolescents who were intrinsically motivated for physical activity were more fit and thereby less likely to be obese. The findings are consistent with self-determination theory.     

Being Fit and Looking Healthy: Young Women’s and Men’s Constructions of Health and Fitness

We drew on Foucault's notion of ‘practices of the self’ to examine how young people take up, negotiate, and resist the imperatives of a public health discourse concerned with the relationships between health, fitness, and the body. We did this through a discussion of the ways young women and men talk about their own and others' bodies, in the context of a number of in-depth interviews conducted for the Life Activity Project, a study of the place and meaning of physical activity in young people's lives, funded by an Australian Research Council Grant. We found that the young women and men in the study engaged the health/fitness discourse very differently: for the young men, health conflated with fitness as an embodied capacity to do physical work; and for the young women, health was a much more difficult and complex project associated with managing and monitoring practices associated with eating and exercise to maintain an ‘appropriate’ body shape.     

The Effects of Work-Related and Boundary-Related Stress on the Emotional and Physical Health Status of Ordained Clergy

This research is the second component of a three-part series that explores the relationship between stress and health in the clerical profession. The first article (Wells, Journal of Religion and Health 51(1):215–30, 2012) determined that there is an association between two different sources of stress in the clerical profession (work-related stress and boundary-related stress). This research explores the association between these two sources of stress and two different measures of health (emotional health and physical health). Utilizing the same dataset from the previous research (Wells, Journal of Religion and Health 51(1):215–30, 2012), and simple and multiple regression, this research determined that there is a positive association between the two sources of stress (work-related stress and boundary-related stress) and the two measures of health (physical health and emotional health). African-American and obese clergy exhibited lower levels of physical health as stress increased. Clergy with children and those with higher levels of education exhibited lower levels of emotional health as stress increased. African-American clergy consistently exhibited higher levels of emotional health than their White colleagues did. Finally, age and length of time in ministry are associated with higher levels of emotional health but lower physical health status.

Decomposing the within-person and between-person sources of variation in physical activity-cognition associations for low-active older adults

Abstract

Objectives: To examine within-person and between-person sources of variation in the relationship between physical activity and cognition in older adults participating in a walking program. To explore whether demographic, health and fitness variables, and their interactions with activity, are significant predictors of cognition.

Design: Brief longitudinal burst design.

Participants: 118 participants (91 females, mean age?=?72.81?+ 5.24 years).

Main Outcome Measures: Cognition, self-reported moderate-to-vigorous walking and self-reported moderate-to-vigorous physical activity were assessed at baseline and 6, 9, 12 and 16 weeks follow-up. Attendance at weekly walks was also recorded.

Results: Within-persons, changes in physical activity were related to select measures of executive functioning, with increased activity predictive of better cognition (three of four cognitive functions, p<.05). Between-persons, activity was also associated with cognition (two of four cognitive functions, p<.05). Younger age and higher education were related to better cognition. Interactions of demographic, health, and fitness variables with changes in within-person activity were generally non-significant.

Conclusion: The results highlight the importance of distinguishing within- from between-person effects in longitudinal analyses of the association between physical activity and cognition. This stringent within-person test of association underscores the potential value of simple physical activity interventions for improving cognitive function.
