This experiment examined the effects of exposure to physique-salient (PS) and physique non-salient (PNS) exercise videos and the moderating influence of perceived physique discrepancies, on body image, self-presentational concerns, and exercise motivation. Eighty inactive women (M age = 26) exercised to a 30 min instructional exercise video. In the PS condition, the video instructor wore revealing attire that emphasized her thin and toned physique. In the PNS condition, she wore attire that concealed her physique. Participants completed pre- and post-exercise measures of body image, social physique anxiety (SPA) and self-presentational efficacy (SPE) and a post-exercise measure of exercise motivation and perceived discrepancies with the instructor's body. No main or moderated effects emerged for video condition. However, greater perceived negative discrepancies were associated with poorer post-exercise body satisfaction and body evaluations, and higher state SPA. There were no effects on SPE or motivation. Results suggest that exercise videos that elicit perceived negative discrepancies can be detrimental to women's body images.  相似文献

This study examined sex differences in body image change and its correlates over the course of a 12-week strength-training program. Participants were 28 men and 16 women (M age = 21.6, SD = 2.4) who completed pre- and post-intervention measures of body image (Body Areas Satisfaction Scale, Social Physique Anxiety Scale, and Drive for Muscularity Scale) and subjective and objective assessments of body fat, muscularity, and strength. They participated in a 12-week, 5-day/week full-body progressive resistance training program. Significant body image improvements were found for both sexes (p < .05). Correlates of body image change varied somewhat between the sexes. For men, body image improvements were correlated only with subjective physical changes. For women, body image improvements were correlated with subjective physical changes as well as objective increases in strength. These results suggest that although men and women derive body image improvements from strength training, they may benefit for different reasons.  相似文献

ObjectivesThe Exercise and Self-Esteem Model is used as a theoretical framework to describe associations between global self-esteem and physical activity, mediated by perceived athletic competence. We know little about how these associations develop over time in elementary school children. We examined the change in, and associations between, global self-esteem, perceived athletic competence, and moderate-to-vigorous physical activity (MVPA) in children from kindergarten to grade 4. We also investigated if this change and these associations were different for boys and girls.DesignA prospective longitudinal cohort-sequential design that consisted of two cohorts of children.MethodChildren in cohort I were followed from kindergarten to grade 2, and children in cohort II were followed from grade 2 to grade 4. Global self-esteem and perceived athletic competence were measured with the Self-Perception Profile for Children (SPPC) (n = 292; 148 boys), while MVPA was measured with proxy-reports for physical activity filled in by parents (n = 184; 88 boys).ResultsGlobal self-esteem, perceived athletic competence, and MVPA remained stable. Global self-esteem was the same in boys and girls, while boys reported higher levels of perceived athletic competence and were more physically active than girls. The change in global self-esteem was significantly associated with perceived athletic competence and MVPA in girls, but not in boys.ConclusionThere are few developmental changes in global self-esteem, perceived athletic competence, and MVPA from kindergarten to grade 4. The change in global self-esteem was associated with perceived athletic competence and MVPA in girls, but not in boys.  相似文献

The objectifying nature of exercise environments may prevent women from reaping psychological benefits of exercise. The present experiment manipulated self-objectification through an exercise class taught by an instructor who emphasized exercise as either a means of acquiring appearance or health outcomes. The purpose of this study was to test for interactions between the class emphasis and participants’ reasons for exercise (i.e., appearance, health) predicting participants’ state self-objectification, state social physique anxiety, exercise class enjoyment, and future intentions of returning to a similar exercise class. Results, obtained via pre- and post-exercise questionnaires, revealed a significant interaction between class emphasis and health reasons for exercise predicting state self-objectification. Participants with lower health reasons for exercise reported greater state self-objectification in the appearance-focused class compared to those with higher health reasons for exercise. Adopting stronger health reasons for exercise may buffer exercise participants from the more objectifying aspects of the group exercise environment.  相似文献

Social anxiety and eating pathology frequently co-occur. However, there is limited research examining the relationship between anxiety and body checking, aside from one study in which social physique anxiety partially mediated the relationship between body checking cognitions and body checking behavior (Haase, Mountford, & Waller, 2007). In an independent sample of 567 college women, we tested the fit of Haase and colleagues’ foundational model but did not find evidence of mediation. Thus we tested the fit of an expanded path model that included eating pathology and clinical impairment. In the best-fitting path model (CFI = .991; RMSEA = .083) eating pathology and social physique anxiety positively predicted body checking, and body checking positively predicted clinical impairment. Therefore, women who endorse social physique anxiety may be more likely to engage in body checking behaviors and experience impaired psychosocial functioning.  相似文献

There are significant gaps in the literature regarding the behavioural consequences of health anxiety. Although past research indicates that health anxiety is associated with distinctive maladaptive behaviours, such as reassurance seeking, the relationship between health anxiety and wellness-related behaviours, such as physical activity, has not been adequately examined. Given that health anxiety is associated with excessive attempts to ensure health and avoid illness, health anxiety could be potentially related to extreme physical activity, known as exercise dependence. Using the cognitive behavioural model of health anxiety as a framework, this exploratory study investigated the relationships between health anxiety, exercise desire, physical activity, and exercise dependence.Undergraduate university students (n = 144) completed a battery of online measures. Results indicated that only the perceptual component of health anxiety, namely hypervigilance to somatic symptoms, was related to exercise desire and components of exercise dependence. Implications of the findings are discussed and future research avenues are explored.  相似文献

BackgroundRegular exercise is critical for disease prevention, but adherence to public health guidelines is poor. Exercise identity is purported to be associated with exercise behavior maintenance, but the extant literature is largely cross-sectional and of low/modest quality.PurposeTo examine change in exercise identity after completion of a supervised exercise intervention, as well as associations between change in exercise identity and exercise maintenance at 6-months follow-up.MethodsN = 276 insufficiently physically active women were randomized to a 16-week, supervised exercise training intervention with 4 conditions fully crossed on intensity (vigorous/moderate) and duration (long/short). Exercise identity was measured pre- and post-intervention and assessments of exercise motivation and behavior frequency were collected at 6-months post-intervention follow-up.ResultsOn average, participants experienced a statistically significant change in exercise identity over the course of the intervention, t (128) = 7.94, p < .001, but identity change scores did not differ across training conditions, p = .91. Identity change was significantly positively related to changes in other theory-informed, motivation-based determinants of exercise, and predicted an additional 16.17 min of exercise per week, on average, at follow-up, b = 16.76, t (103) = 2.30, p = .023.ConclusionsParticipants experienced increased self-identification with exercise after 16-weeks of training, but training volume did not influence the amount of identity change. As expected, greater change in exercise identity was associated with higher levels of exercise behavior at 6-months post-intervention follow-up (ClinicalTrials.gov number NCT02032628 ).  相似文献

ObjectivesThis study represents ancillary analyses of data published by Raedeke, Focht, and Scales [2007. Social environmental factors and psychological responses to acute exercise for socially physique anxious females. Psychology of Sport and Exercise, 8, 463–487] and examines whether enjoyment or task self-efficacy mediated the relationship between exercise environment (health- or appearance-oriented class atmosphere) and affective responses/future intentions or had independent associations with those outcomes.Design/MethodsAs a context in which to examine mediational relationships, volunteer female college students (N = 99) with high social physique anxiety scores were randomly assigned to a health- or appearance-oriented condition. They completed affect and task self-efficacy measures pre- and post-exercise. Enjoyment and intentions were assessed post-exercise.Results/ConclusionsEnjoyment mediated the relationship of class atmosphere on overall feeling as well as revitalization and exhaustion and partially mediated the relationship of class orientation with engagement and future intentions. Although task self-efficacy was an independent predictor of affective responses and intentions, it did not significantly mediate the effect of the social environment on these outcomes.  相似文献

This study sought to identify and describe comfortable and uncomfortable body-related situations of young women, as well as describe their responses to such situations and strategies they used to cope with body-related threats, using Social Self-Preservation Theory (SSPT) as a guiding framework. Interviews were conducted with college women (N = 23). A theoretical thematic analysis approach was taken to identify, code, and report themes. In general, participants found it difficult to identify specific comfortable situations and responses in those situations. Comfortable situations were characterized by the presence of supportive others and feelings of general calmness and lowered body awareness or self-presentational concerns. Findings regarding uncomfortable body-related situations indicated that the context (e.g., presence of others, body exposure), responses (e.g., embarrassment, inadequacy, awareness of others’ evaluations, faster heart rate), and coping strategies (e.g., avoidance, concealing behaviors) described by participants were consistent with SSPT.  相似文献

Objectives

This study examined how variations in the activity of adolescents might relate to the social influences used by parents. Specifically, mean differences in activity across adolescents (individual differences) as well as variation in activity within adolescents (intra-individual variation) were used to predict the use of family social influence.

Design

A prospective design was used.

Methods

High school students (N = 329) completed measures of activity (six times) and social influences received from family (positive, negative, collaborative) (five times) over a one-year period. A multilevel analysis was used to predict each of the three types of social influence. The predictors included activity in two forms: The individual’s mean level of activity (i.e., individual differences) and activity at the previous time point as a deviation from the individual’s mean activity level (i.e., intra-individual variation).

Results

Controlling for age, gender and school, results revealed that both individual differences in mean activity level (b = 0.04, p < .001) and intra-individual variation in activity (b = −0.02, p = .055) predicted use of collaborative influence. For positive influence, only individual differences in mean activity level was a predictor (b = 0.02, p < .001). Neither form of activity predicted parental use of negative influence.

Conclusions

Results revealed support for the positive relationship between both positive and collaborative types of influence and individual differences in activity that is typically reported in the literature. However, a negative relationship between intra-individual variation in activity and collaborative social influences also was found. This negative relationship, where lower activity than normal by the adolescent was related to a greater use of collaborative influence by the parent, may be indicative of a regulatory form of social influence.  相似文献

ObjectivesThis study aimed to examine the effects of change in perceived teacher achievement goal emphasis in physical education (PE) on physical self-perceptions and self-esteem across the transition to secondary school.Design & methodsA longitudinal design was adopted with three time points, one at the end of primary school and two during the first year of secondary school. Participants (N = 491) were cross-classified by primary (N = 42) and secondary (N = 46) PE class in order to examine the association between perceived class-level teacher-emphasised goals and within-class student goals with self-beliefs.ResultsPersonal approach goals and class perceptions of teacher mastery approach goal promotion were all positively associated with ratings of co-ordination, sport competence, flexibility, and endurance in primary school. More favourable perceptions of coordination, sport competence, strength, flexibility, and endurance during the first year of secondary school were predicted by an increase in performance approach goal emphasis, whereas ratings of sport competence and flexibility were negatively associated with an increase in mastery approach goal emphasis.ConclusionsAlthough not entirely consonant with theoretical predictions, current findings suggest that teacher-emphasised performance approach goals in PE can promote development of several physical self-perceptions in the initial year of secondary school.  相似文献

Widely cited literature assumes habits to be: (1) specific and rigid behavioral responses; (2) in response to location- and timing-stable, external contexts, (3) goal-independent, and (4) enacted without conscious awareness. Hagger (2019) recently reviewed this literature as it applies to the physical activity domain. The purpose of this article is to challenge these assumptions in favor of a habit conceptualization that is more applicable to physical activity: (1) behavioral instigation and/or execution can be habitual, allowing for variable responses to cues; (2) stable contexts can be internal or functional (cued by a preceding action) but may vary in timing and physical location; (3) a shift from external to internal goal dependence may characterize habit development; and (4) types of automaticity other than purely nonconscious enactment may characterize habitual action. I present theory and research that supports these alternative characterizations and discuss their ramifications for physical activity adoption and maintenance via habit.  相似文献

ObjectivesThe effect of physical inactivity on mental health risk is well established; however, less is known about about how psychological distress might deter participation in physical activity. Guided by advancements in the treatment of longitudinal data, the aim of this study was to examine patterns and predictors of change in moderate-to-vigorous physical activity (MVPA) and psychological distress (e.g., feeling nervous, worthless).Design methodAustralian adults (4944 females, Mage = 34.63 years ±5.34; 4322 males, Mage = 37.51 years ±6.14) provided baseline data as part of the Longitudinal Study of Australian Children (LSAC) and were followed for measurements every two years for 10 years.ResultsLatent change score analyses revealed support for a reciprocal effects model, whereby change in MVPA and psychological distress occurred as a function of individuals’ prior levels of, and/or prior change in these variables.ConclusionsThis investigation is the first to document that changes in MVPA and psychological distress are coupled temporally. Notably, we observed that individuals’ distress levels at a given time point predicted subsequent change on both MVPA and distress; a finding which provides novel and important insight into how adults’ activity levels and psychological distress fluctuate relative to one another.  相似文献

We examined the effects of social exclusion and attachment insecurities (anxiety, avoidance) on physical pain sensitivity, hypothesizing that anxiety would predict greater physical pain sensitivity only following social exclusion. Participants were either included in or excluded from a computer-based ball-tossing game and then completed a coldpressor task. Anxious men showed greater physical pain sensitivity when excluded, but not when included. Moreover, individuals (men and women) high on both anxiety and avoidance showed greater physical pain sensitivity when excluded, but not when included. Conclusions: Anxious individuals’ heightened physical pain sensitivity following exclusion is a manifestation of hyperactivation of their attachment systems, and when threatened, avoidant individuals who are also high in anxiety are less successful in deactivating their attachment systems.  相似文献

Hagger (2019) offers an insightful synthesis of recent theoretical and empirical developments in understanding of habit and its relevance to physical activity. This commentary extends coverage of one such advance, namely the distinction between two manifestations of habit in physical activity: habitually ‘deciding’ to engage in activity (i.e. habitual instigation), and habitually ‘doing’ the activity (habitual execution). We explore the rationale for this distinction and argue that most contemporary theory and evidence around habitual physical activity – and by extension, Hagger’s review – implicitly focuses on instigation and neglects execution. We offer hypotheses around the potential roles that habitual execution may play in physical activity. Broadening the scope of inquiry within the field to more fully encompass habitual performance would achieve a more comprehensive and informative account that incorporates concepts of skill acquisition and mastery.  相似文献

ObjectiveWe tested predictions made by the self-control strength model on a day level using ecological momentary assessment methodology. The study examined the relationship between self-control strength and physical exercise in participants who intended to exercise on a regular basis. We hypothesized that individuals would exercise more on days when their self-control strength was high than on days when their self-control strength was low and that trait self-control would moderate this relationship.MethodsN = 63 students aged between 19 and 32 years participated in the study. Self-control strength and physical exercise were assessed daily over a period of 20 days with an electronic diary.ResultsMultilevel analyses revealed that the level of self-control strength was positively associated with physical exercise (p = 0.01), and this relationship was stronger in individuals with low trait self-control than in those with high trait self-control (interaction effect: p = 0.03).ConclusionThese findings highlight the interplay between momentarily fluctuating variables such as self-control strength and dispositional variables such as trait self-control in the prediction of physical exercise.  相似文献

Objectives

This study explored the relationship between social control and behavior by examining both the antecedents of social control use following a physical activity lapse as well as the behavior reaction to the use of social control.

Design

As part of a larger project, high school students (N = 547) were prospectively followed over the course of a year and reported physical activity every two months.

Methods

For this study, 123 adolescents who reported experiencing a physical activity lapse sometime during the year were selected. Family physical activity and adolescent activity prior to the lapse were used to predict family use of social control tactics following the lapse. Use of social control tactics were used to differentiate whether adolescents increased their activity following the lapse or not.

Results

Results revealed that family physical activity predicted use of positive and collaborative social control following an adolescent activity lapse. Adolescent physical activity prior to the lapse also predicted parental use of collaborative social control following the lapse. In terms of the adolescent’s behavior reaction, an increase in collaborative social control following the lapse appeared to differentiate those who reported an increase in activity following the lapse compared with those who reported no increase.

Conclusions

This study provided support for physical activity behavior being both an antecedent and consequence of parental social control.  相似文献

Understanding the malleable factors that underpin people’s ongoing commitment to specific forms of exercise is crucial to facilitate more effective efforts to improve participation rates. To this end, we examined the role of (a) perceiving the members of one’s exercise class to be similar to each other on various dimensions, and (b) possessing a strong social identity as an exercise class member in shaping one’s future participation in that class. During a 3-week intensive sampling period, 779 unique responses were obtained from 278 attendees (who were invited to complete a questionnaire on each occasion they attended an exercise class). On each questionnaire, participants indicated their perceptions of class members’ similarity and their own social identification in relation to the exercise class they had just participated in. Participation was conceptualised as attendance at the same class (i.e., same time and type) the following week and was measured objectively using the fitness facility’s electronic class attendance records. Linear multilevel models showed that participants identified more strongly as members of exercise classes in which they perceived that their fellow attendees were similar to each other: both in general, and in terms of age, physical fitness, and their attitude towards the class. Participants also tended to be more likely to attend a given exercise class the following week to the extent that they reported a strong sense of social identification as a member of that class. These relationships were replicated in a multilevel mediation model, which revealed a significant indirect effect of similarity on class attendance through social identification. Results point to the role that social identification can play in promoting repeated exercise participation and indicate that one way to facilitate exercisers’ greater social identification might be to purposefully create exercise classes and groups comprised of relatively homogenous individuals.  相似文献

The purpose of this study was to explore physique attitudes and self-presentational concerns among women who regularly participate in or instruct group aerobic classes. We were interested in conceptualizations of the ideal body, self-presentational concerns, and the influence of instructors in the group aerobics context. Five instructors and 6 exercisers participated in semi-structured interviews. Two higher order themes were identified from the interview data: (a) perceived body ideals and (b) body image experiences in the group aerobics context. Participants described the ideal body as lean and toned and attainable, but cautioned that being too muscular was unattractive and should be avoided. Exercisers experienced heightened self-presentation during aerobics more than the instructors did. Both exercisers and instructors thought that instructors should serve as body role models.  相似文献

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.  相似文献
