As the prevalence of childhood obesity increases, it is important to examine possible differences in psychosocial correlates of physical activity between normal weight and overweight children. The study examined fatness (weight status) and (aerobic) fitness as Enabling factors related to youth physical activity within the Youth Physical Activity Promotion Model (YPAP). Youth ages 9–11 years (N = 1,103) completed the Children’s Physical Activity Correlates survey and the Children’s Physical Activity Questionnaire. Structural equation modeling was used to analyze the relationships among variables. Overweight children reported lower scores on global self-esteem, perceived competence, attraction to physical activity, and parental influence (Cohen’s d ranging from .23 to .45 for girls; Cohen’s d ranging from .31 to .43 for boys). Weight status showed a small positive direct effect on physical activity (standardized path coefficient = .11), but did not show effects on psychosocial correlates (p > .05). Furthermore, aerobic fitness proved to be a stronger Enabling factor (standardized path coefficient = .26) than weight status within the YPAP model. Future research using the YPAP model may extend its utility as an evaluation framework for youth physical activity intervention studies.  相似文献

The current study examined associations between physical education (PE) class enjoyment and sociodemographic, personal, and perceived school environment factors among early adolescent girls. Participants included 1,511 sixth-grade girls who completed baseline assessments for the Trial of Activity in Adolescent Girls, with 50% indicating they enjoyed PE class a lot. Variables positively associated with PE class enjoyment included physical activity level, perceived benefits of physical activity, self-efficacy for leisure time physical activity, and perceived school climate for girls' physical activity as influenced by teachers, while body mass index was inversely associated with PE class enjoyment. After adjusting for all variables in the model, PE class enjoyment was significantly greater in Blacks than in Whites. In model testing, with mutual adjustment for all variables, self-efficacy was the strongest correlate of PE class enjoyment, followed by perceived benefits, race/ethnicity, and teachers' support for girls' physical activity, as compared to boys, at school. The overall model explained 11% of the variance in PE class enjoyment. Findings suggest that efforts to enhance girls' self-efficacy and perceived benefits and to provide a supportive PE class environment that promotes gender equality can potentially increase PE class enjoyment among young girls.  相似文献

This study evaluated whether the relationship between socioeconomic status (SES) and moderate-to-vigorous physical activity (MVPA) is mediated by social support of peers and parents. A cross-sectional study included students (n = 1182) aged 11 to 18 years who were recruited in 2014 from public schools in Fortaleza, Brazil. Participants completed a questionnaire to assess all variables. Mediation analyses were performed to determine the role of parental support and peer support on the relationship between SES and MVPA. Also, moderated-mediation analyses with estimating of conditional indirect effects were performed in order to identify whether gender is a moderator of the mediating effect. A positive and significant association between SES and MVPA was found among Brazilian students, and social support of parents and peers were significant mediators of this relationship. Conditional indirect effects showed that both parental and peer support had a significant indirect effect among boys; only parental support had a significant indirect effect among girls. These results suggest that improving social support can help reduce the impact of SES on physical activity among Brazilian adolescents.  相似文献

We investigated antecedents of mastery-approach, mastery-avoidance, performance-approach, and performance-avoidance goals in sport. University athletes (n = 230) aged 18-25 years (mean 20.3 years, s = 1.5) completed measures of approach-avoidance goals, perceived parental motivational climate, perceived team motivational climate, perceived competence, and demographics. Multiple regression analyses revealed that mastery-approach goals were positively predicted by perceived competence, mastery team climate, learning/enjoyment parental climate, and gender, with males being higher on these goals than females. Mastery-avoidance goals were predicted positively by learning/enjoyment parental climate and negatively by gender, with females being higher on these goals than males. Performance-approach goals were positively predicted by perceived competence, performance team climate, and gender, with males being higher on these goals than females. Finally, performance-avoidance goals were predicted positively by worry-conducive parental climate. These findings suggest that a mastery or performance climate is related to whether athletes adopt a mastery or performance goal, whereas the perception of competence is associated with whether athletes adopt approach-focused goals. Gender should be considered in future examinations of the approach-avoidance achievement goals in sport.  相似文献

In this study, we examined the patterns of goal orientations, perceived competence, reasons for behaving well and self-reported discipline in school physical education among 511 pupils from years 8 and 9 (mean age 14.2 years). Cluster analyses were conducted on two randomly split subsamples to identify homogeneous groups of pupils on these measures of achievement motivation and discipline. Three meaningful clusters emerged for the first subsample, which were then cross-validated for the second subsample. One group of pupils revealed low scores on task and ego orientations, perceived competence and feelings of self-determination about their behaviour in lessons. These perceptions were related to lower ratings of discipline in physical education than pupils who scored more highly on these variables. The highest discipline scores were reported by pupils with high task and ego orientations, perceived competence and feelings of autonomy. The results are useful for teachers and other physical activity leaders in enhancing motivation and disciplined behaviour in young people. Promoting more self-determined reasons for being disciplined, for example, could lead to more orderly classes.  相似文献

The present analysis aimed to describe the degree of tracking of physical activity over an 8-year follow-up period among a cohort of 557 adolescents in western Norway (13 years of age at baseline). Frequency and time spent in leisure-time physical activity were assessed at ages 13, 14, 15, 16, 18, 19 and 21 years through self-report questionnaires. The cross-sectional results indicated that proportions of adolescents who were physically active declined from 13 to 19 years of age and increased slightly from 19 to 21 years of age. Longitudinally, various measures indicated a weak degree of tracking of physical activity (Pearson's r was .22 for boys and. 18 for girls across the 8-year period). The least active persons during early adolescence were those least likely to change during their teenage years. In sum, the findings indicated a weak tendency of tracking of physical activity through adolescence.  相似文献

Influence from parents and friends on adolescents' self-reported level of leisure-time physical activity was examined through measures of (a) perceived leisure-time physical activity of parents and best friend, (b) perceived direct support for physical activity from parents and friends, (c) direct help from parents in exercising vigorously, and (d) perceived value of physical activity of parents and friends. The present analysis included 904 students in western Norway (M age 13.3 years, SD 0.3) who took part in a health behavior survey, which included questions regarding physical activity. Students completed a confidential questionnaire at school. All four measures of influence were positively related to students' activity levels. None of the examined measures was clearly stronger than the other. Parental and peer physical activity level and parental and peer support for physical activity seem to influence the reported physical activity level of the respondents. The findings indicate that, by serving as models and supporters, significant others have an important impact in promoting physical activity in young adolescents.  相似文献

In the present study, we used a model of motivation grounded in self-determination theory (Deci & Ryan, 1985, 1991; Ryan & Deci, 2000a, 2000b, 2002) to examine the relationship between physical education (PE) students' motivational processes and ratings of their effort and persistence as provided by their PE teacher. Data were obtained from 394 British secondary school students (204 boys, 189 girls, 1 gender not specified; M age = 11.97 years; SD = .89; range = 11-14 years) who responded to a multisection inventory (tapping autonomy-support, autonomy, competence, relatedness, and self-determined motivation). The students' respective PE teachers subsequently provided ratings reflecting the effort and persistence each student exhibited in their PE classes. The hypothesized relationships among the study variables were examined via structural equation modeling analysis using latent factors. Results of maximum likelihood analysis using the bootstrapping method revealed the proposed model demonstrated a good fit to the data, chi-squared (292) = 632.68, p < .001; comparative fit index = .95; incremental fit index = .95, standardized root mean square residual = .077; root mean square error of approximation (RMSEA) = .054 (90% confidence interval of RMSEA = .049 -.060). Specifically, the model showed that students who perceived an autonomy supportive environment experienced greater levels of autonomy, competence, and relatedness and had higher scores on an index of self-determination. Student-reported levels of self-determined motivation positively predicted teacher ratings of effort and persistence in PE. The findings are discussed with regard to enhancing student motivation in PE settings.  相似文献

Abstract

This study attempted to validate an anthropometric equation for predicting age at peak height velocity (PHV) in 198 Polish girls followed longitudinally from 8 to 18 years. Maturity offset (years before or after PHV) was predicted from chronological age, mass, stature, sitting height and estimated leg length at each observation; predicted age at PHV was the difference between age and maturity offset. Actual age at PHV for each girl was derived with Preece–Baines Model 1. Predicted ages at PHV increased from 8 to16 years and varied relative to time before and after actual age at PHV. Predicted and actual ages at PHV did not differ at 9 years, but predicted overestimated actual age at PHV from 10 to 16 years. Girls of contrasting maturity status differed in predicted age at PHV from 8 to 14 years. In conclusion, predicted age at PHV is dependent upon age at prediction and individual differences in actual age at PHV, which limits its utility as an indicator of maturity timing in general and in sport talent programmes. It may have limited applicability as a categorical variable (pre-, post-PHV) among average maturing girls during the interval of the growth spurt, ~11.0–13.0 years.  相似文献

This study aims to develop profiles in children according to physical fitness, actual and perceived motor competence, and to examine the level of engagement in physical activity and weight status according to these profiles. In the study, 156 typically developing Spanish children (47.4% girls) of primary school age (5–11 years-old) participated voluntarily. Children’s perceived and actual motor competence, physical fitness, physical activity participation and weight status were assessed. A Self-Organising Map and K-means cluster analysis were used to classify and visualise the values. Four profiles were found: profile 2 was aligned – high capacity, high perception, profile 1 was partially aligned – medium capacity and perception, profile 3 and 4 were both non-aligned – low capacity, medium perception and medium capacity, low perception; respectively. Children in profile 2 were more active than children in profile 3 and 4 (P < .05). In profile 2 there was a lower frequency of overweight/obese children than normal-weight children. On the contrary, in profiles 1, 3 and 4 a similar distribution of normal-weight and overweight/obese children was found. High capable children with high perception exhibited higher physical activity participation and were more likely to be of normal-weight compared to those with low capacity and/or perception.  相似文献

Perceived and actual motor competence (MC) influence physical activity (PA) behaviour. Notably, both are lower in girls than in boys. This study aimed to investigate (i) whether a 12-week, teacher-led intervention that improves actual MC (Lander, N., Morgan, P. J., Salmon, J., & Barnett, L. M. (2017). Improving early-adolescent girls’ motor skill: A cluster randomized controlled trial. Medicine and Science in Sports and Exercise. 49(12), 2498–2505) could also improve adolescent girls’ physical self-perception and perceived MC, and (ii) whether change in actual MC is associated with post-intervention perceptions A randomized controlled trial with 171 girls (mean age 12.48 ± 0.34 years), measured perception (i.e., physical self-perception profile (PSPP) and pictorial scale of perceived movement skill competence (PMSC)) and actual MC (i.e., Victorian FMS Teachers’ Assessment Manual). Mixed models with post-intervention perception as the outcome, adjusting for baseline perception, group, and change in actual MC, as well as clustering, were performed. An interaction term between change in MC and intervention status was included to test the secondary aim. There were significant intervention effects on girls’ physical self-perception as well as their perceived MC. However, there was no association between change in actual MC across the intervention and post intervention perception. While the intervention improved both actual MC and perceived MC, they were not associated.  相似文献

Using a multitheory approach, this study was designed to investigate the influence of urban adolescents' perceived autonomy and competence in physical education on their physical activity intentions and behaviors during leisure time. A transcontextual model was hypothesized and tested. Urban adolescents (N=653, ages 11-15 years) completed questionnaires assessing relevant psychological constructs and moderate to vigorous physical activity and then had their cardiorespiratory fitness assessed with the Progressive Aerobic Cardiovascular Endurance Run (PACER) test. Based on our structural equation modeling analyses and fit indexes, the transcontextual model adequately fit the data. We concluded that the two theoretical frameworks--SDT and theory of planned behavior--can be integrated to provide an enhanced understanding of the influence of physical education on leisure-time physical activity. The results revealed that perceived autonomy and competence in physical education are interrelated and function as a whole for enhancing leisure-time physically active intentions and behavior.  相似文献

Associations between fundamental movement skills (FMS), perceived competence, enjoyment and physical activity (PA) have not been widely investigated among Chinese school children. We hypothesised that FMS would be directly related to self-reported and objectively measured PA, and indirectly related to these outcomes via perceived physical and movement skill competence, and enjoyment. Participants were 763 primary school children (age = 9.3 ± 1.7 years; 474 girls) across grades. FMS were measured for a subsample (n = 603) using Test of Gross Motor Development-2. PA using accelerometers was obtained from this subgroup (n = 238). All participating children completed a questionnaire measuring their PA participation, enjoyment, and perceived physical and movement skill competence. Structural equation modelling revealed positive associations between locomotor skills and perceived movement skill competence (β = .11, 95% CI [.001, .22]), and between perceived movement skill competence and objectively measured PA (β = .59, 95% CI [.04, 1.14]). Perceived physical competence and enjoyment mediated the association between locomotor skills and self-reported PA (β = .08, 95% CI [.02, .12]), but not objectively measured PA. Given inconsistent findings for subjective and objective measures of PA, further mediation analyses of the association between FMS and PA may be warranted.  相似文献

Abstract

The purpose of this study was to gain a better understanding of the contribution of parental socialization processes and gender to children's interest in physical activity using Eccles' expectancy-value model of motivation. An additional purpose was to examine the nature of these relationships among children of a lower socioeconomic level, a sample that has been underrepresented in pediatric exercise research to date. Fourth- through sixth-grade children (N = 107) from a large metropolitan school district were participants in this study and completed questionnaires assessing attraction to physical activity, perceived physical competence, and perceptions of their parents' physical activity beliefs and behaviors. Multivariate regression analyses revealed a significant relationship between parental socialization processes and children's perceived physical competence and attraction to physical activity. Gender differences were also identified and were primarily related to liking of the exertional characteristics of physical activity and exercise. These findings are consistent with theory and research regarding parental and gender-role socialization during childhood.  相似文献

This paper explores socio-ecological factors and their interplay that emerge from a qualitative study and influence adolescents' physical activity and sport participation. A total of 13 boys and 7 girls active and inactive adolescents, from years 12 and 13 and different types of school (state and private), participated in semi-structured interviews. It followed a purposeful sampling selection from participants who participated in a previous larger study on physical activity levels. Findings highlight the influence of personal and social interplay, such as perceived competence, obesity and teasing from peers, and new social demands and personal preferences in adolescents' (dis)engagement in physical activity and sport. They also stand out how social and environmental factors affect their participation, such as family, boy/girlfriends, physical education and rural/urban places of residence. These factors appear to have an important impact on the construction of (in)active identities during late adolescence. Policy makers, exercise professionals and educators should be aware of these factors in order to improve health promotion strategies and social policies. Some recommendations are also indicated in the paper.  相似文献
