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

Active commuting among school children is being encouraged for physical and environmental reasons, but little is known about its influence on affect. The aim of this study was to test the hypothesis that children who walk further to school experience increased arousal and affective valence compared with children who walk a short distance. This was assessed with the children's feeling scale (CFS) and children's felt arousal scale (CFAS). Distance walked to school and affective change between home and school were assessed over a 2-week period in 99 children between 5 and 10 years of age. Home to school differences in CFS and CFAS scores were compared in children who walked a short (100–300 m); medium (301–500 m), and long distance (over 500 m). Although differences were not always statistically significant, there was evidence that the children who walked further reported a greater increase in their CFAS scores between home and school (average η2 = .08, range: .01–.15) and, to a lesser extent, in their CFS scores (η2 = .04, range: .002–.06). Further research is needed to explore whether there is an optimum walking distance and the contribution of other factors, especially social contacts during commuting, the environment, and the weather.  相似文献

Current concerns about a childhood obesity crisis and children's physical activity levels have combined to justify fitness lessons as a physical education practice in New Zealand primary (elementary) schools. Researchers focused on children's understandings of fitness lessons argue that they construct fitness as a quest for an ‘ideal’ (skinny or muscular) body. The conflation of fitness with thinness, however, is complex and problematic. In this paper, we draw from research conducted with a class of primary school children in New Zealand. Drawing on the theoretical tools of Foucault and utilizing a visual methods approach, we examine how children experience school fitness lessons and construct notions of fitness, health and body. The children's responses illustrated that obesity discourses and body pedagogies ‘collided’ in a way that shaped understandings of fitness lessons in ways inextricably connected with the avoidance of being fat. The children assumed that fitness lessons increased fitness and that being fit was demonstrated by a ‘correct’ corporeal appearance. We argue that body pedagogies inside and outside the school gates shape children's ideas about the body in ways which exclude other understandings of bodies, health, and physical activity.  相似文献

ABSTRACT

Effective and sustainable strategies for physical activity promotion during childhood are of considerable importance to physical education, sport, and health organisations. Multi-component physical activity intervention approaches for children and young people are firmly rooted within the literature; however, there is a dearth of research evidence pertaining to healthy lifestyle promotion within and beyond the school environment. ‘Promoting active lifestyles in schools’ represents a valuable resource for teachers seeking to integrate health-related learning and encourage physically active students. The essential ingredients within this book are the active pedagogies and the health-related learning strategies for children from the ages of 5 to 16 years. Through a consistent formula, this book positions the longitudinal process of health-related learning at the centre of its practice, by providing age-appropriate learning outcomes, activities and assessment strategies within and beyond the school environment. This review seeks to examine the focus of the book and consider its contribution to the existing empirical evidence base within the fields of physical education, health education and physical activity promotion.  相似文献

The present study examined the sex-specific associations of moderate and vigorous physical activity (VPA) with physical fitness in 300 Japanese adolescents aged 12–14 years. Participants were asked to wear an accelerometer to evaluate physical activity (PA) levels of various intensities (i.e. moderate PA (MPA), 3–5.9 metabolic equivalents (METs); VPA, ≥6 METs; moderate to vigorous PA (MVPA), ≥3 METs). Eight fitness items were assessed (grip strength, bent-leg sit-up, sit-and-reach, side step, 50?m sprint, standing long jump, handball throw, and distance running) as part of the Japanese standardised fitness test. A fitness composite score was calculated using Japanese fitness norms, and participants were categorised according to their score from category A (most fit) to category E (least fit), with participants in categories D and E defined as having low fitness. It was found that for boys, accumulating more than 80.7?min/day of MVPA may reduce the probability of low fitness (odds ratio (ORs) [95% confidence interval (CI)]?=?0.17 [0.06–0.47], p?=?.001). For girls, accumulating only 8.4?min of VPA could reduce the likelihood of exhibiting low fitness (ORs [95% CI]?=?0.23 [0.05–0.89], p?=?.032). These results reveal that there are sex-specific differences in the relationship between PA and physical fitness in adolescents, suggesting that sex-specific PA recommendation may be needed to improve physical fitness in adolescents.  相似文献

Abstract

Numerous epidemiological investigations have shown that low physical fitness and low physical activity are related to the incidence of coronary artery disease (CAD). Most studies, however, have not examined both variables concurrently to determine which has the strongest association with CAD risk. The purpose of the investigation was to cross-sectionally examine the relationships among physical fitness, physical activity, and risk factors for CAD. Male law enforcement officers (N = 412) from the City of Austin, Texas, were subjects for this study. Physical fitness, physical activity, and risk factors for CAD were assessed through health screenings and from data collected as part of an annual physical fitness assessment. Multivariate analysis of covariance revealed that physical fitness, but not physical activity, was related to several single CAD risk factors. Percent body fat, smoking habits, and Type A behavior score were negatively related to physical fitness level, and high density lipoprotein (HDL) cholesterol was positively related to physical fitness level. Univariate analysis of variance found both physical fitness and physical activity to be significantly related to a composite CAD risk score. Low physical fitness and low physical activity were associated with a high CAD risk score. These data suggest that physical activity must be sufficient to influence physical fitness before statistically significant risk-reducing benefits on single CAD risk factors are obtained, although minimal engagement in weekly vigorous activity provides a significant benefit for the composite CAD risk score. It is plausible, however, that physical fitness is a stronger measure than physical activity and optimally characterizes the relationship among physical activity and CAD risk factors.  相似文献

Abstract

This paper summarizes the development of an inventory for the assessment of children's attitudes toward physical activity (CATPA), including an overview of its psychometric properties. Through a series of studies, an original and frequently used attitude inventory was restructured, resulting in a revised inventory which is both shorter and psychometrically superior to the original. This instrument, which assesses attitudinal dispositions toward each of seven physical activity subdomains, is shown to possess high internal consistency and strong factor validity. In addition, a new CATPA inventory suitable for grade 3 children is introduced. The two inventories are presented, along with instructions for their administration and scoring. Norms, based on samples of approximately 500 children of each grade and sex, are provided for boys and girls in grades 3, 7, and 11. Throughout the paper consideration is given to research applications, as well as cautions relative to the use and interpretation of the two CATPA inventories.  相似文献

Purpose: The purpose of this study was to determine the extent to which a sport education season of fitness could provide students with recommended levels of in-class moderate-to-vigorous physical activity (MVPA) while also increasing students’ fitness knowledge and fitness achievement. Method: One hundred and sixty-six 5th-grade students (76 boys, 90 girls) participated in a 20-lesson season called “CrossFit Challenge” during a 4-week period. The Progressive Aerobic Cardiovascular Endurance Run, push-ups, and curl-ups tests of the FITNESSGRAM® were used to assess fitness at pretest and posttest, while fitness knowledge was assessed through a validated, grade-appropriate test of health-related fitness knowledge (HRF). Physical activity was measured with Actigraph GT3X triaxial accelerometers. Results: Results indicated a significant time effect for all fitness tests and the knowledge test. Across the entire season, the students spent an average of 54.5% of lesson time engaged in MVPA, irrespective of the type of lesson (instruction, free practice, or competition). Conclusions: The results suggest that configuring the key principles of sport education within a unit of fitness is an efficient model for providing students with the opportunity to improve fitness skill and HRF knowledge while attaining recommended levels of MVPA.  相似文献

Participation in youth sport is assumed to promote and contribute towards more physically active lifestyles among children and adolescents. The aim of this study was to examine inter-participant variability in objectively measured habitual physical activity (PA) behaviours and sedentary time among youth sport participants and their implications for health. One-hundred-and-eighteen male youth sport footballers (Mean ± s = 11.72 ± 1.60) wore a GT3X accelerometer for 7 days. Average daily PA [min · day?1, in light (LPA), moderate (MPA), vigorous (VPA) and combined moderate-to-vigorous (MVPA)] and sedentary time were calculated. Participants’ body mass index adjusted for age and sex (BMI–standard deviation score), per cent body fat (BF%), waist circumference and cardiorespiratory fitness were assessed. Results revealed that variability in daily PA behaviours and sedentary time (min · day?1) was associated with BMI–standard deviation score [VPA (?), MVPA (?)], BF% [sedentary time (+), VPA (?), MVPA (?)], waist circumference [sedentary time (+), LPA (?)] and cardiorespiratory fitness [sedentary time (?), MPA (+), VPA (+), MVPA (+)]. Whilst sedentary time and MVPA were not related to health outcomes independent of one another, associations with markers of adiposity and cardiorespiratory fitness were stronger for sedentary time. Sedentary time was also significantly positively related to waist circumference independent of VPA. Results demonstrate inter-participant variability in habitual PA and sedentary time among youth sport participants which holds implications for their health. Thus, promoting PA and, in particular, reducing sedentary time may contribute towards the prevention of adverse health consequences associated with a physically inactive lifestyle for children and adolescents active in the youth sport context.  相似文献

This study compared step counts detected by four, low-cost, objective, physical-activity-assessment instruments and evaluated their ability to detect moderate-to-vigorous physical activity (MVPA) compared to the ActiGraph accelerometer (AG). Thirty-six 10–11-year-old children wore the NL-1000, Yamax Digiwalker SW 200, Omron HJ-151, and Walk4Life MVP concurrently with the AG during school hours on a single day. AG MVPA was derived from activity count data using previously validated cut points. Two of the evaluated instruments provided similar group mean MVPA and step counts compared to AG (dependent on cut point). Low-cost instruments may be useful for measurement of both MVPA and steps in children's physical activity interventions and program evaluation.  相似文献

Preschool physical education has not been extensively researched. Furthermore, research in physical activity and physical education rarely seeks young children's perspectives. The current paper focuses on one aspect of a post-structural study concerned with investigating the place and meaning of ‘physical education’ to practitioners and children at three preschool contexts in Scotland. The paper details the research methods employed to investigate the children's perspectives. It aims to encourage and assist other researchers to include young children in qualitative research related to physical education and physical activity. Furthermore, it is proposed that elements of the research approach taken, and methods and resources employed, may be transferable to other contexts, and therefore may assist in engaging other diverse populations in research related to physical education, physical activity and sport.  相似文献

Abstract

Evidence suggests the development of fundamental movement skill (FMS) is a key factor in promoting long-term physical activity. Low levels of activity among preschool children and the relationship between physical activity and the development of fundamental movement skills underline the need to determine the factors associated with children's development of such skills. As parents play an important role in the socialization process, the aim of this study was to examine correlates of family and neighbourhood characteristics as well as parental behaviour and beliefs on FMS performance in 4- to 6-year-old preschool children. Relationships between preschool children's FMS performance and family contextual variables were examined within a sample of 846 preschool children. Results identified positive associations of FMS performance with parental education, father's physical activity, transport to school by bicycle, and the high value placed by parents high on sport-specific aspects of children's physical activity. Variables negatively associated with preschool children's FMS performance included father–child interaction in TV-viewing and reading books, the high importance placed by parents on winning and performance in children's physical activity. Furthermore, the ambiguity of associations between FMS performance and parental beliefs underlined its complexity.  相似文献

Abstract

A large proportion of a child's day is spent at school interacting with certain physical surroundings, teachers, and school friends. Thus, schools could have a marked impact on establishing physical activity habits. The aim of the present study was to assess between-school variation in physical activity, aerobic fitness, and organized sports participation. Altogether, we tested 1766 nine- and fifteen-year-old children attending 242 school classes at 35 different schools in Denmark in 1997–2003. The intra-class correlation coefficient (ICC) for objectively assessed physical activity ranged between 0.06 and 0.18 depending on the dimension of physical activity and the time considered (i.e. school time vs. leisure time). For aerobic fitness, an ICC of 0.10 was observed, whereas that for organized sports participation ranged between 0.01 and 0.10 depending on the age group. Studying between-school variation in physical activity provides information about the extent to which children adjust their physical activity habits according to the social and environmental circumstances that they share, and helps to plan future school-based physical activity studies, especially in terms of sample size and power calculation.  相似文献

ABSTRACT

This paper examined effects of two interventions on cardiorespiratory fitness and motor skills, and whether these effects are influenced by baseline levels, and dose of moderate-to-vigorous physical activity (MVPA) during the intervention. A cluster randomized controlled trial was implemented in 22 schools (n = 891; 9.2 ± 07 years). Intervention groups received aerobic or cognitively engaging exercise (14-weeks, four lessons per week). Control groups followed their regular physical education programme. Cardiorespiratory fitness, motor skills and MVPA were assessed. Multilevel analysis showed no main effects on cardiorespiratory fitness and motor skills although the amount of MVPA was higher in the aerobic than in the cognitively engaging and control group. Intervention effects did not depend on baseline cardiorespiratory fitness and motor skills. Children with a higher dose of MVPA within the intervention groups had better cardiorespiratory fitness after both interventions and better motor skills after the cognitively engaging intervention. In conclusion, the interventions were not effective to enhance cardiorespiratory fitness and motor skills at a group level, possibly due to large individual differences and to a total dose of MVPA too low to find effects. However, the amount of MVPA is an important factor that influence the effectiveness of interventions.  相似文献

The main purpose of this study was to develop a Rasch Measurement Physical Fitness Scale (RMPFS) based on physical fitness indicators routinely used in Hong Kong primary schools. A total of 9,439 records of students' performances on physical fitness indicators, retrieved from the database of a Hong Kong primary school, were used to develop the Rasch scale. Following a series of iterative Rasch analyses that adopted the “data should fit the model” approach, four physical fitness indicators (i.e., 6-min run, 9-min run, 1-min sit-ups, and dominant handgrip) were successfully calibrated to form the RMPFS. The RMPFS and its scale indicators showed fit to the Rasch model sufficient for the intended purposes of measuring the overall fitness of children. The overall physical fitness measure reflects children's fitness on three key core components of physical fitness (i.e., cardio-respiratory fitness, muscular endurance, and muscular strength). Advantages of the RMPFS are discussed, and recommendations for future research follow. The findings of this study provide a better knowledge basis for interpreting children's physical fitness assessment results.  相似文献

Abstract

The purpose of this cross-sectional study was to examine the relationship between objectively measured physical activity, sedentary time, and cardiorespiratory fitness in a diverse sample of youth. Participants were recruited from three middle schools and completed assessments of height, weight, cardiorespiratory fitness, and wore an accelerometer for a minimum of four days. Hierarchical general linear models controlling for age, body mass index (BMI) percentile, and sex were used to evaluate the association of time (minutes per day) spent sedentary, and in moderate physical activity and vigorous physical activity with cardiorespiratory fitness (i.e., heart rate response [beats per minute], dependent variable). Results indicated age (β = –0.16, P < 0.05), BMI percentile (β = 0.33, P <0.05), being male (β = 0.17, P < 0.05), sedentary time (β = 0.11, P <0.05), moderate (β = –0.03, P > 0.05) and vigorous (β = –0.22, P < 0.05) physical activity explained 29% of the variance in cardiorespiratory fitness. Evaluation of fitness among high sedentary/high vigorous, high sedentary/low vigorous, low sedentary/low vigorous, and low sedentary/high vigorous groups (defined by the median split) showed that high levels of vigorous activity removed the detrimental effect of high levels of sedentary time on cardiorespiratory fitness. These analyses suggest that the negative impact of sedentary time can be mitigated by engaging in vigorous activity.  相似文献

Abstract

Levels of physical inactivity and sedentary behaviour among English and Spanish youth are high and vary within different regions of each country. Little though is known about these during specific periods of the day. The purpose of this study was to describe physical activity (PA) and sedentary time during segments of the day and week, and compare these critical contexts between youth in the Liverpool and Madrid areas of England and Spain, respectively. PA was objectively assessed in 235 Liverpool- and 241 Madrid youth (aged 10–14 years) who wore accelerometers for seven consecutive days. Minutes of sedentary time, moderate PA, vigorous PA and moderate-to-vigorous physical activity (MVPA) were calculated for weekdays, weekend days, school time, non-school time and after-school. Between-country differences were analysed using analysis of covariance (ANCOVA). Madrid youth spent significantly more time in sedentary activities than their Liverpool counterparts. Madrid youth engaged in more minutes of moderate intensity physical activity (MPA) than Liverpool youth during weekdays, school time and non-school time (P<0.01). Liverpool children recorded more time in vigorous physical activity (VPA) than Madrid peers during week days and weekend days (P<0.01) and during school time and after-school periods (P <0.01). The MVPA was significantly higher among Madrid youth during non-school time (P<0.01). Around 25% of all youth achieved recommended levels of MVPA. Low levels of MVPA and systematic differences in sedentary time, MPA and VPA exist between Liverpool and Madrid youth. Interventions targeted at the least-active children during weekends, after-school and non-school periods within the cultural contexts common to each city are required.  相似文献
