Motives for and barriers to physical activity participation in middle-aged Chinese women

ObjectivesThis study examined differences in motives for and in barriers to physical activity participation in middle-aged Chinese women between activity levels and motivational styles.DesignCross-sectional study.MethodsChinese middle-aged women (N=360) completed a battery of questionnaires about level of physical activity, reasons for and barriers to physical activity participation, and general motivational style.ResultsEighty percent of the women were classified into precontemplation, contemplation, or preparation stages of physical activity, indicating the majority were not physically active enough to achieve health benefits. Fitness–health, enjoyment–interest and appearance were found to be the most important motives for, and lack of time, resources or skills and family or friend support the most important barriers to participation. Women in the later stages of physical activity behavior were more likely to exhibit greater motive strengths and to perceive fewer barriers compared to those in the earlier stages. Among a number of motivational style results, women in the later stages were found to be more arousal-seeking and to rate challenge of activities and improving competence higher than women in the earlier stages. Also, having a mastery motivational style and a higher income were strong predictors of physical activity participation in these middle-aged women.ConclusionThe findings of the present study extend the literature by providing insights into how women's motives for and barriers to physical activity participation are related to their activity levels and motivational styles. The implications of the results for physical activity promotion and provision with regard to benefiting women's health are discussed.     

Momentary affective response to bouts of moderate-to-vigorous physical activity predicts changes in physical activity and sedentary behavior during behavioral weight loss

BackgroundAffective responses are posited to be key predictors of the uptake and maintenance of health behaviors. However, few studies have examined how individuals’ affective response to physical activity, as well as the degree to which their affect response changes, may predict changes in physical activity and sedentary time during behavioral weight loss treatment.PurposeThe current study examined how baseline momentary affective response (i.e., stress and anxiety) to moderate-to-vigorous physical activity (MVPA) and the degree of pre--post intervention change in this response predicted change in daily sedentary, light, and MVPA time during a three-month internet-based weight loss program.MethodsWomen with overweight/obesity (final N = 37) completed 14-day ecological momentary assessment (EMA) protocols with objective measurement of physical activity (i.e., bout-related MVPA time) before and after the intervention.ResultsWomen who had more reinforcing responses to MVPA (i.e., greater reductions in anxiety and stress response following MVPA bouts) at baseline had greater increases in overall MVPA at the end of the intervention. Those who had greater anxiety reductions after MVPA bouts at baseline also evidenced less sedentary time at the end of the intervention. Changes in affective responses across the intervention were not related to changes in physical activity levels.ConclusionsFindings suggest initial levels of affective reinforcement from MVPA bouts predict future change in MVPA and sedentary time during behavioral weight loss. Future work is needed to examine the utility of more precisely targeting affective responses to physical activity to optimize intervention approaches.     

Relationship between changes in acute exercise-induced feeling states,self-motivation,and adults' adherence to moderate aerobic exercise

A 14-wk. field study was conducted to estimate a correlation between feeling-state changes induced by moderate (50 to 74% VO2 max; 20 to 30 min.) bouts of cardiovascular exercise and attendance in a new exercise program. Three groups of men and women (ns=22 to 24) were formed for comparative analysis based upon participants' self-motivation (high, medium, low), as measured by the Self-motivation Inventory. Analysis indicated that for the low self-motivation group, attendance was positively correlated with before-to-after exercise difference scores in the Exercise-induced Feeling Inventory subscales of Positive Engagement (r(s)=.48), Revitalization (r(s)=.47). and Tranquility (r(s)=.41) and negatively correlated with difference scores in the Physical Exhaustion subscale (r(s)=-.62). Conversely, for the high self-motivated group generally weaker correlations in the opposite direction were found for each subscale. No definitive pattern was found for the medium self-motivation group. Multiple regression analyses conducted with scores on each Exercise-induced Feeling Inventory subscale supported the moderating effect of Self-motivation Inventory score on exercise attendance: Multiple R2s =.20 to .27. Although limited amounts of the total variance in exercise attendance was explained, practical implications are drawn for prescribing exercise by feeling states. Limitations and replication of results using different types samples and types of exercise are discussed.     

Achievement goal orientations,beliefs about sport success and sport emotions as related to moderate to vigorous physical activity of adolescents

Abstract

This study examined the relationships between achievement goals, beliefs about sport success and sport emotions with moderate to vigorous physical activity of Estonian adolescents. Three hundred and seventy five adolescents, aged 13–14 years, completed the Task and Ego Orientation in Sport Questionnaire and 7-day physical activity recall. Measures of the adolescent's orientation to work avoidance, focus on cooperation, beliefs about the causes of success and degree of satisfaction/interest specific to the context of sport and games were also included. Moderate to vigorous physical activity (MVPA) quartiles were determined and psychological measures for extreme activity groups were compared. A one-way ANOVA indicated that active males scored significantly higher in task orientation, motivation/effort, ability and enjoyment/interest whereas active females showed higher scores for cooperation and exercise enjoyment and lower deception and boredom compared with low activity groups. Correlation analysis revealed that in males, MVPA was related with task orientation, reported ability and motivation/ effort. For females, cooperation, and enjoyment of sport were positively and the amount of boredom was negatively associated with MVPA scores. Multiple regression analysis revealed that psychological measures explained only 14% (females) and 19% (males) of the variance in MVPA. It is concluded that for adolescent males and females, different psychological measures predicted MVPA behavior.     

Examining predictors of physical activity among inactive middle-aged women: an application of the health action process approach

This study tested several relationships predicted by the Health Action Process Approach (HAPA) in a sample of 175 generally healthy, inactive, middle-aged women (40-65 yrs old) over a 12 week period. Participants' physical activity, risk perceptions, outcome expectancies, action self-efficacy and intention were measured at baseline. Planning and maintenance self-efficacy were measured 4 weeks later. Physical activity behaviour was measured 12 weeks after baseline. The HAPA relationships were examined using a structural equation model. The data fit the model well and revealed several significant relationships. Action self-efficacy was the best predictor of intention. Maintenance self-efficacy was the best predictor of planning and behaviour. Contrary to the tenets of HAPA and to past research, planning did not predict behaviour. Overall, HAPA provides a useful framework for identifying determinants of physical activity intentions and behaviour within a group of inactive, middle-aged women.     

Reciprocal relationships between three aspects of physical self-concept,vigorous physical activity,and lung function: A longitudinal study among late adolescents

ObjectivesThis prospective study, of older adolescents, investigated relationships between three aspects of physical self-concept, vigorous physical activity and lung function. In particular, physical competence, general appearance evaluations and body areas satisfaction were expected to predict subsequent physical activity, which, in turn, was expected to explain variation in lung function. In line with the reciprocal effect model, bi-directorial relationships were also tested. Gender was expected to moderate hypothesized relationships.DesignA longitudinal design, with three measurement points (baseline, 2-month follow-up, and 14-month follow-up) was employed.Method551 late adolescents (15–18 years old) provided self-reported data on physical activity, physical competence, body areas satisfaction, and appearance evaluation. Body weight, height, and a lung function index (forced expiratory volume in 1 s, FEV₁) were measured at baseline and at the 14-month follow-up.ResultsModerated mediation analyses indicated that physical competence at baseline predicted vigorous physical activity (2-month follow-up) among young men and women. Baseline body satisfaction and appearance evaluation were also related to vigorous physical activity (2-month follow-up) and this relationship was stronger for men. Vigorous physical activity predicted FEV₁ (14-month follow-up) and this relationship was stronger among women. The reciprocal pattern of relationships was not confirmed.ConclusionsFindings suggest that health promoting interventions should focus particularly on vigorous physical activity among young women, for example by boosting their physical competence.     

Predictors of personal investment in physical activity among middle-aged and older adults

The purpose of this study was to determine the relationship between the social psychological components of Personal Investment Theory and exercise behaviors among 47 middle-aged and older men and women participating in an organized exercise program. Specifically, the degree to which personal incentives for exercise, perceptions of sense of self (i.e., physical self-efficacy, fitness locus of control, self-motivation, social identity), and the congruence between program and participants' goals predict present physical activity and estimated future physical activity was examined. Multiple regression analyses indicated that present and future exercise behaviors significantly related to social psychological variables reflecting personal investment.     

Adoption and maintenance of physical activity: Planning interventions in young, middle-aged, and older adults

Young, middle-aged, and older adults in orthopaedic outpatient rehabilitation (N?=?373) were randomly assigned to either an interviewer-assisted or a standard-care self-administered planning intervention. Physical activity planning consisted of specifying action plans to facilitate action initiation, and coping plans to overcome barriers. The interviewer-assisted condition led to more complete action plans and a longer duration of physical activities up to six months after discharge. Regarding coping planning, older and middle-aged adults benefited more from interviewer-assisted planning while younger adults benefited more from self-administered planning. Planning as such was found to be an effective tool for enactment irrespective of chronological age. The delayed effect of coping planning on enactment suggests that coping planning is important for long-term maintenance.     

‘Active’ating thoughts about affect: elicitation of physical activity judgements in insufficiently active women

Objective: A growing body of evidence suggests that affective judgements are distinct from, and exert greater influence on, physical activity behaviours than instrumental judgements.

Design: As part of a randomised controlled trial, 110 insufficiently active, female, university students were randomised to (a) an affective mental contrasting condition, (b) an instrumental mental contrasting condition, or (c) a ‘standard’ mental contrasting intervention (with no modifications). In the analyses concerning the trial’s primary outcome, the affective mental contrasting condition was found to be more effective for increasing physical activity than the standard or instrumental conditions. The purpose of this study was to qualitatively examine the physical activity outcomes and obstacles elicited from participants as part of the three mental contrasting interventions within this trial.

Results: 32 lower-order physical activity judgement themes, categorised within seven high-order themes, were derived through the use of the mental contrasting intervention. In addition to identifying several affective and instrumental outcomes and obstacles that have previously been recognised, participants in this study also highlighted contextualised responses that describe complicated relationships that exist between affective and instrumental judgements.

Conclusions: This study provides fine-grained insight into cognitive processes derived from a novel intervention involving insufficiently active women.     

Relationship of feeling states after exercise and Total Mood Disturbance over 10 weeks in formerly sedentary women

Changes in feeling states after exercise and changes in overall mood after a period of 10 weeks were correlated after participation in a supervised, moderate intensity resistance training program. 52 previously sedentary, asymptomatic women (M=56 yr.) participated. Point biserial correlations were calculated between the 10-wk. change on the Profile of Mood States using the Total Mood Disturbance score as the continuous variable, and positive or negative change in feeling states after exercise, assessed via the Exercise-induced Feeling Inventory, being the dichotomous variable. Correlations were significant for both the total sample (rpb=-.49) and participants with high initial Total Mood Disturbance based on a median split (rpb=-.55). Participants with positive changes in their feeling states after exercise also showed a significantly greater decrease in Total Mood Disturbance than those with negative changes. Changes in Total Mood Disturbance were not significantly correlated with changes in resting heart rate over the 10 weeks. Discussion included limitations and, after replication, possible application of the findings.     

Marital interaction, family organization, and differences in parenting behavior: explaining variations across family interaction contexts.

Family systems theories remind us that, in two-parent families, children encounter their parents in multiple family configurations, including parent-child dyads and mother-father-child triads, or whole families. There are, however, relatively few empirical investigations of differences in parenting behavior which tend to emerge when a dyad is transformed into a whole family unit. Using a sample of 82 families with a kindergarten-age child, the present study offers support to earlier studies reporting that mothers' and fathers' parenting behavior differs when observed in dyadic and whole family interaction sessions. The present study then turns to examining explanations for these differences in parenting behavior. Limited support was found for the hypothesis that observations of marital interaction are associated with differences in parenting behavior across family interaction contexts. Family level assessment of adaptive organization was found to explain differences in fathers' parenting in the dyad and when the entire family is together, but not differences in mothers' parenting behavior. The clinical and methodological implications of these findings are discussed.     

Comparison of barriers self-efficacy and perceived behavioral control for explaining physical activity across 1 year among adolescent girls.

The absence of longitudinal data about correlates of physical activity during adolescence has hindered the identification of key mediator variables that can be targeted by interventions. Building on the authors' previous report of a cross-sectional analysis, this study compared barriers self-efficacy and perceived behavioral control as predictors of change in 2 levels of physical activity across a 1-year period among a sample of Black and White adolescent girls (N=1,038). Self-efficacy did not predict change in either moderate or vigorous physical activity. In contrast, perceived behavioral control exhibited a longitudinal, independent relationship with change in vigorous physical activity. The authors concluded that perceived behavioral control is an independent predictor of change in vigorous physical activity levels across a 1-year period among a sample of Black and White adolescent girls and warrants study as a potential mediator variable in interventions designed to increase or maintain physical activity.     

Psychosocial mediators of a lifestyle physical activity intervention in women

ObjectivesA lifestyle physical activity intervention in women based on the transtheoretical model and social–cognitive theory effectively increased physical activity. The aim of the present study was to examine possible mediators (perceived benefits and barriers of physical activity, self-efficacy, processes of change, and social support) of these physical activity changes.MethodsMembers of four units of a women's organization followed a six-month minimal-contact physical activity program. The intervention program included one group meeting, a self-help booklet and five monthly reminder letters. Members of two other units served as control group. Physical activity (accelerometer counts), and psychosocial constructs (self-report questionnaires) were assessed at baseline (pretest) and directly after the intervention (posttest). Women who completed all measurements (n = 101) were included in the mediation analyses.ResultsParticipants in the intervention group reported significantly greater increases in the use of behavioral processes from pretest to posttest than participants in the control group. None of the proposed psychosocial constructs showed a mediating effect on changes in physical activity.ConclusionsThe mechanisms proposed by the transtheoretical model and social–cognitive theory could not explain the positive effect of the intervention on physical activity. Identifying the working components of an intervention remains a challenging and necessary step in the development of effective low-cost and high-reach physical activity interventions.     

Self-determined motivation in physical education and its links to motivation for leisure-time physical activity, physical activity, and well-being in general

The present study tested a trans-contextual model based on self-determination theory of the relations between motivation in physical education, motivation in leisure-time physical activity, physical activity, and psychological well-being. Participants were 329 Norwegian upper secondary school students (M age = 16.5 yr., SD = 0.7). Students' perceptions of autonomy-supportive teachers in physical education were expected to be positively associated with students' psychological needs satisfaction in physical education, which was expected to be positively related to autonomous motivation for physical education participation. In turn, autonomous motivation for physical education was expected to be positively associated with perceived competence and autonomous motivation for leisure-time physical activity, which both were expected to be positively associated with leisure-time physical activity and psychological well-being in general. Structural equation models and bootstrapping supported the hypotheses and the indirect links between variables. Sex differences indicate that more research is needed on how to motivate girls to be more physically active in leisure time.     

Relations between physical activity, weight discrepancies, body-cathexis, and psychological well-being in college women

This study examined the relations between physical activity, weight discrepancies, body-cathexis, and indicators of psychological well-being in college women. Factor analysis and zero-order correlation, and partial correlation analyses show that physical activity was not directly related to psychological well-being, however, physical activity did reduce weight discrepancies and improved body-cathexis. When specific body types were examined, there were distinctive patterns of satisfaction with body parts and processes depending on whether the women's body types conformed to or deviated from idealized weights and heights.     

Personal and environmental factors associated with physical inactivity among different racial-ethnic groups of U.S. middle-aged and older-aged women.

Personal, program-based, and environmental barriers to physical activity were explored among a U.S. population-derived sample of 2,912 women 40 years of age and older. Factors significantly associated with inactivity included American Indian ethnicity, older age, less education, lack of energy, lack of hills in one's neighborhood, absence of enjoyable scenery, and infrequent observation of others exercising in one's neighborhood. For all ethnic subgroups, caregiving duties and lacking energy to exercise ranked among the top 4 most frequently reported barriers. Approximately 62% of respondents rated exercise on one's own with instruction as more appealing than undertaking exercise in an instructor-led group, regardless of ethnicity or current physical activity levels. The results underscore the importance of a multifaceted approach to understanding physical activity determinants in this understudied, high-risk population segment.     

A content analysis of print media coverage of gender,women and physical activity

Abstract

This paper presents the results of an investigation of print media coverage of gender and physical activity. The analysis was based on an examination of two samples: all issues of four Canadian daily newspapers for a 6-m-onth period and all issues of Chatelaine, a monthly Canadian women's magazine, for a period of 10 years and 6 months. Results indicate the media provide little support for the promotion of women's physical activity and little challenge to gender stereotyped imagery of physical activity. This is particularly true for newspapers, which are a largely conservative influence in the contemporary fitness movement. The magazine analysis indicates Chatelaine plays a positive if limited role in the promotion of women's fitness and physical activity.     

To see or not to see: effects of exercising in mirrored environments on sedentary women's feeling states and self-efficacy.

Effects of a mirrored exercise environment and body image concerns on changes in exercise-induced feeling states and self-efficacy were examined among 58 sedentary women (mean age = 20.7 years). Participants performed a 20-min bout of exercise in front of either a mirrored or a nonmirrored wall. Feeling states and self-efficacy were measured pre- and postexercise. Multilevel linear modeling indicated that regardless of their level of body image concern, women in the mirrored condition felt worse after exercising than women in the unmirrored condition. There were no effects of the environment or body image on self-efficacy. Results are consistent with predictions of objective self-awareness theory and have implications for promoting exercise among sedentary women.
