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 (Mage = 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.  相似文献

Background: Evidence linking fitness and decreased psychosocial stress comes from studies of athletes and typically relies upon self-report measures. Furthermore, there is little evidence regarding the impact of physical activity (PA) prior to a stressor. The aims of this study were to determine whether fitness and prior PA influence cortisol concentrations during psychosocial stress.

Methods: Seventy-five non-athletic participants took part in a submaximal walk prior to the Trier Social Stress Test for Groups (TSST-G). During the walk, fitness was assessed using heart rate (HR). A further 89 participants took part in the TSST-G without the walk. Stress responsiveness was assessed using salivary cortisol collected at 10-min intervals on seven occasions.

Results: Hierarchical multiple regression revealed that average walking HR accounted for 9% of the variance in cortisol secretion (P?=?.016), where a higher HR was associated with higher cortisol secretion. Between-subjects ANCOVA revealed that the walking group had a significantly lower cortisol secretion than the non-walking group (P?=?.009).

Conclusions: These findings indicate that fitter individuals have reduced cortisol secretion during psychosocial stress. They also indicate that prior PA can reduce cortisol concentrations during psychosocial stress and are suggestive of a role of PA in reducing the impact of stress on health.  相似文献

BackgroundAggressive behaviour is a substantial behavioural problem in children and adolescents. This review systematically summarises the current evidence on the relationship between physical activity participation and aggressive behaviour and quantifies the effects of physical activity interventions on aggression in children and adolescents.MethodsStudies were identified through a search of five electronic databases (PsycINFO, SPORTDiscus, MEDLINE, CINAHL and Web of Science) with combinations of three groups of keywords. Two independent reviewers screened and extracted data from the individual studies. The reporting quality and publication bias were assessed. The relationship between physical activity participation and aggressive behaviour was systematically summarized. Data (effect sizes) were pooled to investigate the effects of physical activity interventions on aggressive behaviour. A moderator meta-analysis was performed to identify potential moderators of the effects of physical activity interventions on aggressive behaviour.ResultsNineteen studies met the inclusion criteria. The relationship between physical activity participation and aggressive behaviour was mixed. A significant reduction in aggressive behaviour was observed after physical activity interventions (k = 8, SMD = −0.53, 95% CI [−0.27, −0.79], p < 0.001). The moderator meta-analysis showed that physical activity interventions involving team-based physical activity had greater effects than those involving individual-based physical activity (β = 0.42, SE = 0.18, p = 0.02). In addition, interventions involving physical activity alone were more effective in reducing aggressive behaviour than those that combined physical activity with other activities such as a philosophy course (β = −0.63, SE = 0.11, p < 0.001).ConclusionThe current meta-analysis presents evidence for the effect of physical activity interventions on aggressive behaviour in children and adolescents. Physical activity–only interventions involving team-based physical activity might be used for preventing or reducing aggressive behaviour in children and adolescents. Possible mechanisms, methodological strengths and weaknesses, implications, and suggestions for future studies were discussed.  相似文献

Though the effect of action planning upon behavioural enactment is becoming well-established, adherence to planning interventions are modest. Motivations specific to action planning may predict planning behaviour. The primary purpose of the present study was to determine if theory of planned behaviour constructs operationalized for planning could predict change in planning behaviour. The secondary purpose was to determine if planning behaviour predicted changes in physical activity. Participants (n = 337, Mage = 31 ± 5) were adults with intentions to be more active who completed measures of affective and instrumental attitudes towards planning, subjective norms towards planning, perceived behavioural control over planning, intentions to plan, self-reported planning behaviour, intentions to be active and self-reported physical activity at baseline (T1) and after four weeks (T2). Affective attitudes towards planning (β = 0.10, p < .05), instrumental attitudes towards planning (β = 0.22; p < .01) subjective norms over planning (β = 0.12, p < .01) and perceived behavioural control over planning (β = 0.53, p < .01) predicted intentions to plan (adj. R2 = 0.66). Intentions to plan (β = 0.16, p < .05) and intentions to be active (β = −0.25, p < .05) predicted change in planning behaviour (R2change = 0.03). Planning behaviour (β = 0.27, p < .05) predicted change in physical activity (R2change = 0.07). Planning behaviour appears to have its own motivations distinct from those of physical activity. Future interventions should target planning behaviour along with its motivations and control beliefs to increase rates of planning. The theoretical underpinnings of the TPB are of value for understanding both planning behaviour and physical activity.  相似文献

It has been demonstrated that physical activity has a small but positive effect on cognition in old age, which suggests that it may be possible to alter the trajectory of age-related cognitive decline. However, our understanding of which aspects of physical activity that are important for modifying cognition remains incomplete. Adopting an exploratory approach in a sample of 115 healthy older adults (65–75 years), the present cross-sectional study used structural equation modelling to investigate the dissociable associations of physical activity (moderate-to-vigorous activity, derived from 7-day accelerometry) and cardiorespiratory fitness (VO2 max, derived from maximal treadmill ergometer test) with multiple latent cognitive abilities (working memory, episodic memory, spatial and verbal reasoning). The results showed a significant positive association between fitness and working memory, when physical activity was statistically controlled for, and a positive association of similar point magnitude between physical activity and episodic memory, when fitness was statistically controlled for, although the latter association did not reach statistical significance. The results add to the foundation for a more careful investigation of the dissociable associations of moderate-to-vigorous physical activity and fitness with cognition in old age, and encourages future research to test the hypothesis that cardiorespiratory fitness benefits working memory via general cerebrovascular effects on grey matter volume, whilst moderate-to-vigorous physical activity benefits episodic memory via effects on neuroplastic processes.  相似文献

PurposeThis large-scale, exploratory study sought to examine the associations between motor skill proficiency (MSP), perceived self-competence (PC), physical fitness (PF), and self-reported physical activity (PA) to assess the assumption that relationships among these variables found in childhood and adolescence persist into young-adulthood. Specifically, predictors of PF and PA were assessed. Additionally, the contributions body mass index (BMI) and gender made to these relationships, as well as that of process- versus product-oriented motor skills data, were studied. Finally, how these relationships differed by gender was explored.MethodsParticipants’ (n = 448) MSP was assessed using select measures from the TGMD-2 and the BOT-2, while PF was evaluated using the FitnessGram. Participants also completed surveys to assess PC (SPPCS), PA (past-week MAQ), and demographic information. Height and weight were collected to calculate BMI.ResultsModels predicting physical fitness had good fit to the observed data, with perceived athletic competence, locomotor skill, upper-limb coordination, BMI, and gender accounting for about 75% (R2 = 0.748) of aerobic PF variance and about 48% (R2 = 0.476) of variance in push-up performances. About 18% (R2 = 0.178) of variance in curl-up performances was predicted by perceived athletic competence, locomotor skill, upper-limb coordination, and PA. The PA model demonstrated weaker predictive power, with only about 10% (R2 = 0.097) of variance explained. When considering male and female models separately, female models demonstrated better fit when predicting all PF and PA outcome variables. BMI and gender operated as significant predictors to differing degrees across the various models.ConclusionsThere is compelling evidence to believe relationships found among MSP, PC, PF, and PA in childhood and adolescence also exist in early adulthood. However, differences in the roles of gender and physical fitness versus physical activity are likely to exist.  相似文献

This article reports the development and exploratory testing of a school-based intervention programme designed to enhance levels of physical activity in adolescents. The intervention is based on social cognitive theory (SCT), self-regulation theory (SRT) and planning as evidence-based mediators of physical activity changes. Two classes, paired on socio-economic variables, were selected from each of eight Portuguese schools and randomly assigned to an intervention or control group (N = 291). Primary outcome was ‘moderate to vigorous physical activity’ (International Physical Activity Questionnaire) measured pre and post intervention and at three and nine months follow-up. SCT, SRT and planning variables were secondary outcomes measured pre and post intervention. At post test, participants in the intervention group reported 18 min per week more physical activity (PA), adjusted for pre-intervention, age and sex, than those in the control group (95% confidence interval ?10 to 46; p = 0.249). This difference increased to 33 min (95% CI–4 to 71; p = 0.082) at three months and to 57 min (95% CI 13 to 101, p = 0.008) at nine month follow-up. Moreover, the intervention resulted in changes of some of the theoretical target variables, including outcome expectancies and coping planning. However, no evidence was found for the changes in theoretical moderators to mediate the intervention effects on behaviour. Implications for theory and for future research are discussed.  相似文献

New evidence-based physical activity (PA) guidelines and recommendations for constructing messages supplementing the guidelines have been put forth. As well, recent reviews have identified theoretical constructs that hold promise as targets for intervention: self-regulation, outcome expectancies and self-efficacy. The purpose of this study was to examine the integration of messages targeting self-regulation, self-efficacy and outcome expectancies in existing physical activity brochures. Twenty-two PA brochures from Canadian and American National Health Organizations were assessed for their use self-efficacy, self-regulatory processes and outcome expectancies. Brochures were analyzed line-by-line using a modified version of the validated Content Analysis Approach to Theory-Specified Persuasive Educational Communication (CAATSPEC; Abraham, Southby, Quandte, Krahé, & van der Sluijs, 2007). Two independent raters coded a third of the brochures (n = 7). Inter-rater reliability was acceptable for 17 of the 20 categories (rs > .79). Discrepancies in all categories were discussed and agreement was reached. The remaining brochures were coded by one of the two raters. Usage of the three key theoretical constructs accounted for only 36.43% of brochure content (20.23% self-efficacy, 10.40% outcome expectancies, 5.80% self-regulation). Brochures lacked the use of a variety of theoretical strategies, specifically goal-setting, planning and verbal persuasion and rarely highlighted the affective benefits of physical activity. In the future brochures should aim to place increased emphasis on self-regulation, self-efficacy, and affective outcome expectancies.  相似文献

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.  相似文献

ObjectivesBased on previous research that has identified affective attitude as a distinct predictor of physical activity (PA) behavior, the purpose of this pilot study was to elicit affective beliefs toward physical activity using qualitative data generated through specific open-ended questions.MethodsA sample of 126 undergraduate students participated in this study. Four open-ended questions based on the theory of planned behavior were posed to elicit affective beliefs. A content analysis was used to categorize and code data by theme based on common responses that emerged in the elicitation. A frequency count of the responses falling into each category was then conducted to establish which affective beliefs were the most common. The themes were established by two researchers and reviewed for internal homogeneity and external heterogeneity by a third party.ResultsThe results highlight key beliefs related to affective attitude. In descending rank order; Social Involvement, Pleasant Body States, Esteem, Improved Psychological Outcome, and General Enjoyment were the most common affective beliefs for PA involvement. Feelings arising from Time Issues/Conflict, Physical Unpleasantness, PA Environment, and Necessity/Obligation were the most common negative affective beliefs.ConclusionsThe results suggest that promoting enjoyment rather than necessity of PA and encouraging variety in PA may be effective. Addressing the importance of aesthetically pleasing environments and highlighting social interaction as a strategy rather than merely a norm or a form of support in behavioral research may be important.  相似文献

PurposeExamine the association between health-related physical fitness (cardiorespiratory fitness and muscular fitness) and skill-related physical fitness (speed-agility) and both cognitive functions and academic achievement in adolescents (12–15 years).MethodsData of 423 Dutch adolescents were analyzed (46.8% boys, age = 13.45 ± 0.43 years). Physical fitness was assessed using five subtests of the Eurofit test battery measuring cardiorespiratory fitness (20 m Shuttle Run Test), muscular fitness (Broad Jump and Sit-Ups) and speed-agility (10 × 5 m Shuttle Run Test and Plate Tapping Test). Cognitive functions were assessed by the Digit Span Task, the Grid Task and an adapted version of the Attention Network Test. Finally, academic achievement was assessed by two standardized tests assessing mathematic skills and language skills. Multilevel regression analyses were performed in MlWin to examine the relations of interest adjusting for sex and age.ResultsMultilevel regression analysis showed that speed-agility was significantly related to visuospatial working memory (β = 0.159; p = 0.014), information processing and control (β = 0.238; p < 0.001) and interference control (β = 0.156; p = 0.039), but not to the other cognitive or academic achievement outcomes. Cardiorespiratory fitness and muscular fitness were not related to any of the cognitive or academic achievement outcomes.ConclusionThe results suggest that skill-related physical fitness is related to cognitive functions and health-related physical fitness is not. Therefore it can be argued that improved levels of skill-related physical fitness may lead to improved cognitive functioning.  相似文献

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.  相似文献

Background/ObjectiveThe aim of the study was to analyze the relationship between being bullied and the physical fitness components, and to determine whether a healthy physical fitness level is related with lower victimization in children and adolescents with overweight and obesity compared to unfit overweight/obese peers. Method:The present cross-sectional study included a total of 7,714 youths (9-17 years), categorized as normal-weight or overweight/obese and fit or unfit according to sex-specific handgrip strength and cardiorespiratory fitness (CRF) cut-points. Bullying (physical, verbal, social exclusion, sexual harassment, and cyberbullying) was assessed through the Standard Health Behavior in School-aged Children survey questions. Results:Boys and girls that were categorized as fit (healthy level of CRF) showed lower traditional bullying compared to unfit counterparts. Also, a healthy level of CRF could be a protective factor of traditional bullying among overweight/obese youths compared to unfit overweight/obese peers. Conclusions:CRF is related with lower risk for experiencing traditional bullying in Latino youths with and without obesity, thus emphasizing the role of fitness even among youth with excess of adiposity.  相似文献

BackgroundPhysical inactivity is a world-wide health issue. In people with major depressive disorders approximately 68% do not reach the recommended physical activity levels. Psychosocial determinants of and implicit attitudes towards physical activity serve to explain physical activity behavior and may form the basis of interventions to promote physical activity. The aim of this study was to examine, whether psychosocial determinants and implicit attitudes towards physical activity vary according to depression severity.MethodsPhysically inactive, adult in-patients diagnosed with major depressive disorder (according to ICD-10) were recruited from four Swiss psychiatric clinics. Psychosocial determinants of physical activity were assessed with seven questionnaires pertaining to motivational and volitional aspects of physical activity. Implicit attitudes towards physical activity were measured with a computer-based Single Target Implicit Association Test.ResultsIn-patients (N = 215, Mage = 41 ± 13 years, 53% female) with major depressive disorder reporting more severe (n = 52) depression symptomology exhibited less favorable psychosocial determinants for physical activity behavior (self-efficacy, negative outcome expectancies, intention, intrinsic motivation, introjected motivation, external motivation, action planning, perceived barriers, coping planning) compared to those with mild (n = 89) and moderate (n = 74) depression symptomology. Positive outcome expectancies, identified, social support and implicit attitudes towards physical activity did not vary according to depression severity.ConclusionsPsychosocial determinants of physical activity do vary according to depression severity. Attempts to promote physical activity among people with major depressive disorder should take depression severity into account when developing and delivering interventions.Trial registrationISRCTN registry, ISRCTN10469580, registered on 3rd September 2018, https://www.isrctn.com/ISRCTN10469580.  相似文献

Objectives

Overweight youth are frequent targets of weight-based victimization during Physical Education (PE) and sports. In addition, previous research indicates that teachers’ perceptions and expectations may influence their likelihood of intervening during victimization, and physical educators may endorse biased perceptions and expectations of overweight youth. Despite this evidence, no research has examined how physical educators respond to weight-based victimization of their students. Thus, the current study examined PE teachers’ and coaches’ responses to different types of victimization involving average weight and overweight students.

Design

This study utilized an experimental design that assessed participants’ reactions to situations of weight-related victimization using hypothetical scenarios accompanied by photographs of youth.

Methods

PE teachers and sport coaches (N = 162) were randomly presented with a scenario and follow-up questions about an average weight or an overweight student. Each participant completed two conditions: one with a male target, and one with a female target.

Results

Participants were more likely to take action when overweight female students were victims of bullying, specifically in situations of verbal and relational victimization. Male participants were less likely to respond to victimization than female participants.

Conclusions

Findings suggest the importance of increasing awareness about weight-based victimization and its consequences, especially among male physical educators. Implications for the psychological, social, and physical development of overweight youth are discussed.  相似文献

ABSTRACT

Emerging evidence indicates that practicing gratitude contributes to well-being. The goal of this investigation was to develop a comprehensive, effective intervention for promoting gratitude among adolescents and young adults (ages 16–30). Findings from experimental data indicate that three existing gratitude activities (three good things, benefit appraisals, and a gratitude letter) fostered unique facets of gratitude (Study 1). A combined intervention enhanced gratitude, hope, and prosocial intentions among young adults (Study 2) and adolescents (Study 3). This work extends the literature by providing empirical evidence on how benefit appraisal influence adults, revealing the unique effects of existing gratitude activities, and showing that an integrative intervention is effective for both adolescents and young adults. Furthermore, the resulting intervention is relatively brief and can be implemented online or in-person, which could facilitate widespread dissemination. Implications and directions for future research are discussed.  相似文献

ObjectivesThis systematic review provides an overview of research elucidating the relationship between fundamental movement skills (FMS) and physical activity (PA) in children and adolescents.DesignSystematic review.MethodProspective studies were identified from searches in Cochrane Library, BioMed Central, Education Resources Information Center (ERIC), PubMed, Scirus and SciVerse Science Direct from 2000 through 2013. We screened the titles and abstracts for eligibility, rated the methodological quality of the studies, and extracted data.ResultsWe identified 23 studies meeting our relevancy criteria. The quality score of the studies ranged from 44% to 89%. Overall relationships between FMS and PA or relationships specific for gender and skill were identified in several studies. The variety of methods for assessing PA and FMS make the comparison of study results difficult. We found strong evidence from cross-sectional studies for a positive relationship between FMS and organized physical activities. Motor skill competency was only of low predictive value for the physical activity level in adults.ConclusionsThe results of this review suggest that a cause–effect relationship between FMS and PA is suspected but has not been demonstrated yet. The identification of a causal relationship appears very important to ensure feasibility of practical implementation. This could provide aids for decision making for teachers and coaches, but also for therapists' decision guidance to create training, lessons and therapy adequate to the target group.  相似文献

ObjectivesThe purpose of the current study was to examine the relationship between physical fitness and interference control by comparing higher and lower fitness children with attention deficit hyperactivity disorder (ADHD) using event-related potentials (ERPs) and behavioral indices.DesignCross-sectional design was employed.MethodEighty children, previously diagnosed with ADHD, were evaluated on their inhibitory ability as measured during their participation in the flanker task, and this ability was examined in relationship to measures of their physical fitness. Only children in the top 40% or in the bottom 40% of the distribution for each fitness components were included in the statistical analysis.ResultsThe results showed that children with higher levels of muscular endurance, muscular power, and aerobic capacity had shorter reaction times (RT) and larger P3 amplitudes compared to less fit children. In addition, children with lower body composition had shorter reaction times and shorter P3 latencies compared to those with higher body composition.ConclusionsBetter physical fitness, especially muscular endurance, muscular power, aerobic capacity, and body composition, were associated with enhanced interference control in children with ADHD. Our findings suggest the need for a closer examination of the possible impact of different aspects of fitness on the general relationship between physical fitness and cognition.  相似文献
