This study examined differences in children’s body mass index (BMI) and body fatness (BF%) as a function of gender and fundamental movement skill (FMS) proficiency. Following ethics approval and parental consent, 248, 6–11 year-old children (112 boys, 136 girls) underwent assessment of 7 FMS: sprint run, side gallop, hop, kick, catch, throw and vertical jump. FMS tertiles (“high”, “medium” or “low” FMS) were created based on the summed components of the FMS. Skinfold measures were used to calculate BF%. Physical activity (PA) was assessed using pedometry and maturation predicted using anthropometry. Data were analysed using a 2 (Gender) × 3 (FMS tertile) ways analysis of covariance (ANCOVA), controlling for age, maturation and PA. Age (P = .001) and maturation (P = .006) were associated with BMI. Girls classified as high FMS proficiency had significantly lower BMI compared to girls with low and medium FMS proficiency. Age (P = .0001) and maturation (P = .007) were associated with BF%. BF% was also higher for girls with low FMS compared to those with medium and high FMS. BF% and BMI were not different across FMS tertile in boys. Such findings suggest focusing on FMS may be especially important for healthy weight, particularly in girls. 相似文献

The purpose of this study was to examine knee extensor/flexor muscle strength and physical activity in healthy males and females approaching retirement. Peak torques of the knee extensor and knee flexor muscle groups were measured bilaterally in 95 individuals (mean age 59.4 years) using an isokinetic dynamometer. Isokinetic concentric contractions were performed at angular velocities of 1.05 and 3.14 rad x s(-1). Physical activity, including household, leisure, and sporting activities, was assessed. The results show that the average peak torques exhibited were lower than previously reported in studies using the same methodology with different populations of similar age and body size. Over one-third of the participants were sedentary, with just 13% being active enough to obtain health benefits. The poor muscle strength and low physical activity of this self selecting group of healthy working adults were surprising, and potentially a cause for concern. The combination of retirement being a potential watershed for a decrease in physical activity and the known age-related decline in physical performance indicates that some of these participants are at risk of losing their functional independence fairly early in the retirement stage. We recommend the introduction of effective health promotion interventions for individuals approaching retirement, encouraging them to become more physically active. 相似文献

In a primary-care led National Health Service it is imperative for librarians not only to develop user-centred services for health professionals based in the community but also to facilitate information management within Primary Care Groups. In this article recent research in the field is discussed, and challenges intrinsic to delivering information services to primary care are identified. Drawing on the experience of one Practice Librarian in the Aylesbury area, the importance of organizational culture is considered, along with its implications for making successful approaches to partnerships. Five factors that motivated these practices to contract the services of an independent librarian are identified. The information needs of Primary Care Groups are discussed and the essential characteristics of future service provision are noted. 相似文献

The effects of two types of self-determined reinforcement contingencies on children's test performances were investigated and compared to each other and to externally determined contingencies. In Experiment I, fourth-grade children's test performances were measured for three baseline sessions utilizing self-assessment and self-recording and three contingency sessions. Three contingency conditions resulted in significant and comparable increases in total test performances over a noncontingent reinforcement control: externally determined contingencies set in advance of performance, self-determined contingencies set in advance of performance when children were trained in contingency selection, and self-determined contingent points that children awarded themselves after performance. In a condition in which children self-determined contingencies but had no training in how to set contingencies, the results were not significantly greater than the control. In Experiment II, contingencies were introduced for a longer period of time to two fifth-grade classes. The comparable increases in test performance through externally determined and self-determined contingencies set in advance of performance when children were trained in contingency selection persisted over the three weeks. It was suggested that self-management that includes self-determined contingencies of reinforcement procedures may provide useful and cost effective techniques that educational consultants may recommend for classroom implementation. 相似文献

The current study examined the social and language development of 345 Spanish-speaking pre-kindergartners who attended pre-kindergarten programs that varied widely in how much Spanish was spoken in the classroom by the teacher. Previous studies on English language learners have focused on how the language of instruction impacts children's language proficiency, ignoring the context in which children are learning. The current study found better social skills and closer teacher—child relationships in classrooms where teachers spoke some Spanish. Teacher ratings of children's peer social skills and assertiveness were positively associated with increased amounts of Spanish being spoken. More Spanish language use in the classroom was also related to a decrease in children's likelihood of being victims of aggression as rated by independent observers. The findings have implications for better understanding how policy decisions regarding language of instruction impact children in the social domain. As early education programs are faced with the challenging task of developing best practices for English language learners, it is essential that programs are attentive to the social implications of language. 相似文献

The purpose of this paper is to identify communication skills recognized as essential for success in work group contexts. Results from interviews and a survey conducted with a sample of personnel managers identified communication skills considered important for success in work group settings, the most critical of which was effective listening. The abilities to receive information and later transmit that information to fellow group members, and to give effective informative presentations in a group setting were characterized as the least crucial of the skills identified. Implications for group research and pedagogy are discussed. 相似文献

This study examined the relationships among college students’ civic values and behaviors, college culture, and college involvement,
accounting for their pre-college inclinations toward civic responsibility. Using a longitudinal, national dataset comprised
of 3,680 college students, the study employed structural equation modeling to identify a model that suggests social activism
goals mediate the relationship between co-curricular engagement and charitable involvement behaviors. 相似文献

Using data collected as part of the second pilot administration of Your First College Year (YFCY), a national survey of first-year college students, this study was designed to examine both response rates and nonresponse bias across four survey administration groups: paper-only, paper with web option, web-only with response incentive, and web-only without response incentive. Findings indicate that response rates vary by mode of administration. Moreover, predictors of response differed by administration group. Results are discussed in light of the recent surge of interest in online survey research. 相似文献
