通过以我国学生体质健康评价制度的演变和发展为导线,以我国学生体质健康测试项目为切入点,利用文献法、比较法、数理统计法对学生体质健康测试项目中400米跑与50米×8往返跑进行差异性研究。研究结果表明,在同一名学生身上测得的400米跑与50米×8往返跑项目成绩是具有显著性差异的,在学生体质测试项目上规定的五、六年级50米×8往返跑项目不能用400米跑项目进行简单的代替(或替换)。如果用400米跑代替50米×8往返跑进行学生体质测试,可能会造成比较大偏差,从而影响学生体质健康等级判定的准确性。  相似文献

This study aimed to establish between-day reliability and validity of commonly used field-based fitness tests in youth soccer players of varied age and playing standards, and to discriminate between players without (“unidentified”) or with (“identified”) a direct route to professional football through their existing club pathway. Three-hundred-and-seventy-three Scottish youth soccer players (U11–U17) from three different playing standards (amateur, development, performance) completed a battery of commonly used generic field-based fitness tests (grip dynamometry, standing broad jump, countermovement vertical jump, 505 (505COD) and T-Drill (T-Test) change of direction and 10/20 m sprint tests) on two separate occasions within 7–14?days. The majority of field-based fitness tests selected within this study proved to be reliable measures of physical performance (ICC?=?0.83–0.97; p?p?2 (7)?=?101.646, p?相似文献

ABSTRACT

The feasibility requirements of administering field-based cognitive assessments are rarely reported. We examined the feasibility of administering a group-based cognitive test battery in a school setting with older adolescents. Several types of reliability were also assessed in the control group. Preliminary efficacy and the relationship between changes in fitness and changes in cognitive control were also explored following a 14-week HIIT intervention (3 sessions/week). Participants completed a cognitive test battery measuring inhibition (flanker), and working memory (n-back) at baseline and post-test. Health-related fitness assessments were also conducted. Test administration took approximately 30.8 ± 1.5 minutes to complete with up to six participants simultaneously. The test battery demonstrated acceptable reliability (ICC = 0.5–0.81), with significant changes observed for flanker incongruent accuracy, and 2-back non-target accuracy from baseline to post-test. Regarding efficacy, small-to-moderate effects were observed for accuracy outcomes, while several small associations were found between changes in fitness and changes in cognition. Findings from the current study suggest a cognitive test battery can be administered with older adolescents in a school setting. However, there remains a lack of adequate reporting of administration requirements for field-based cognitive assessments. Efficacy findings should be confirmed with a larger and more representative sample of older adolescents.  相似文献

Purpose: This exploratory study examined the notion of Seefeldt's (1980) hypothesized motor skill “proficiency barrier” related to composite levels of health-related physical fitness (HRF) in young adults. Method: A motor skill competence (MSC) index composed of maximum throwing and kicking speed and jumping distance in 187 young adults aged 18 to 25 years old was evaluated against a composite index of 5 health-related fitness (HRF) test scores. MSC (high, moderate, and low) and HRF indexes (good, fair, and poor) were categorized according to normative fitness percentile ranges. 2 separate 3-way chi-square analyses were conducted to determine the probabilities of skill predicting fitness and fitness predicting skill. Results: Most correlations among HRF and MSC variables by gender demonstrated low-to-moderate positive correlations in both men (12/15; r = .23–.58) and women (14/15; r = .21–.53). Chi-square analyses for the total sample, using composite indexes, demonstrated statistically significant predictive models, χ 2 (1, N = 187) = 66.99, p < .001, Cramer's V = .42. Only 3.1% of low-skilled (2 of 65) individuals were classified as having a “good” HRF. Only 1 participant (out of 65) who demonstrated high MSC was classified as having “poor” HRF (1.5%). Conclusion: Although individual correlations among individual MSC and HRF measures were low to moderate, these data provide indirect evidence for the possibility of a motor skill “proficiency barrier” as indicated by low composite HRF levels. This study may generate future research to address the proficiency barrier hypothesis in youth as well as adults.  相似文献

ABSTRACT

Background: Fitness testing is a commonly applied learning and teaching practice implemented in both secondary and elementary school physical education (PE). Many teachers believe that by using a variety of different tests, they are able to provide students with feedback regarding their fitness status, and furthermore, increase students’ willingness to be physically active later in their lives. However, empirical evidence concerning students’ affective responses during fitness testing classes is limited.

Purpose: The primary aim of the study was to investigate whether students’ perceptions of enjoyment and anxiety differed between two different types of fitness testing classes and PE in general. In addition, the measurement invariances over time and between Grade 5 (aged 11–12) and Grade 8 (aged 14–15) groups were determined.

Method: A total sample of 645 Finnish Grade 5 (N?=?328, 50% boys, mean age?=?11.2, SD?=?0.36) and Grade 8 students (N?=?317, 47% boys, mean age?=?14.2, SD?=?0.35) participated in the study. Series of multi-group confirmatory factor analyses were conducted to test the level of measurement invariance between general PE and fitness testing classes, and between age groups. Strict factorial invariance was supported for both enjoyment and anxiety scales allowing for latent mean comparisons. Latent mean differences were studied using z-tests.

Results: Grade 5 students perceived significantly lower levels of enjoyment and cognitive processes and a higher level of somatic anxiety in fitness testing classes compared to general PE. Additionally, for Grade 8 students, levels of enjoyment and cognitive processes were significantly lower and somatic anxiety and worry higher in fitness testing classes than in general PE. Furthermore, enjoyment was significantly higher, and cognitive processes, somatic anxiety and worry lower among Grade 5 students compared with Grade 8 students in both contextual PE and during fitness testing class.

Conclusion: Results of this study indicate that students’ perceptions of enjoyment were lower in fitness testing classes compared to PE in general. Additionally, students perceived lower levels of cognitive anxiety and higher levels of somatic anxiety in fitness testing classes than in general PE. It is noteworthy that students might not significantly dislike fitness testing per se but instead have significantly more positive affects towards PE in general. Generally, practitioners conducting fitness testing lessons are encouraged to embrace different strategies such as fostering basic psychological needs or promoting mastery climate to facilitate enjoyment and diminish anxiety.  相似文献

ABSTRACT

The aim of this study was to examine the associations of fitness and physical activity with academic achievement in children with overweight/obesity. A total of 106 (10.0 ± 1.1y, 61 boys) children participated. The fitness components were assessed by field and laboratory-based tests. Physical activity was measured via accelerometry. The academic achievement was assessed by a standardised test and school-grades. Field-based cardiorespiratory fitness was associated with language skills (ß-standardised- ranging from 0.281 to 0.365, p < 0.01). The field-based muscular strength was associated with grade point average, natural and social sciences, and foreign language (ß = 0.280–0.326, all p ≤ 0.01). Speed-agility was associated with some language-related skills (ß = 0.325–0.393, all p ≤ 0.01). The laboratory-based muscular strength also showed an association with mathematics skills (ß = 0.251–0.306, all p ≤ 0.01). Physical activity did not show significant association with academic achievement (p > 0.01). Overall, the significant associations observed for muscular strength and speed/agility were attenuated and disappeared in many cases after additional adjustments for body mass index and cardiorespiratory fitness, indicating that these associations are inter-dependent. Our study contributes by indicating that other fitness components apart from cardiorespiratory fitness, such as muscular strength and speed-agility, are positively associated with academic achievement. However, these associations appear to be dependent on body mass index and cardiorespiratory fitness.  相似文献

Abstract

The promotion of cardiorespiratory fitness through increased physical activity has become a national public health objective for both adults and children. Based on numerous small-scale studies it appears that children are highly fit but the population distribution is unknown due to the lack of rigorous population studies. Very little is known about the extent of children's physical activity; the available evidence does not support the hypothesis that children obtain sufficient activity to explain their generally high levels of fitness. Due to the lack of evidence of substantial carry-over effects of youth fitness to adult health and the likelihood of children's resistance to vigorous fitness routines, there is little reason to recommend an aerobic training focus in physical education. A focus on enjoyable moderate to vigorous physical activity (MVPA) with carry-over value to adulthood is recommended. Physical education is an important vehicle for promoting physical activity by children; it appears, however, that children may obtain little MVPA during physical education class.  相似文献

Background: Flamenco is a highly emotional and demanding dance form. It is important to understand how the dancer’s body works in order to improve fitness levels and reduce injuries. Thus, our investigation reviewed studies on kinesiological aspects of flamenco over recent years. Methods: The review was restricted to experimental studies. Literature searches were conducted using the following databases: PubMed, Scopus, and Ebsco: SPORTDiscus with Full Text, Medline, Health Source: Nursing/Academic Edition, Health Source – Consumer Edition. After limiting the search, 180 potential articles remained for analysis. Results: A total of 27 papers on different aspects of flamenco dance were finally selected: biomechanics (14), podiatry (6), injury incidence (3), anthropometry (2), and physiology (2). These studies have applied well-established methods from sports studies. However, we noted a number of potential limitations when applied to flamenco. Conclusions: The evidence from this review shows that flamenco dancing demands high levels of effort. Further research is required to understand how the dancer’s body works in order to improve fitness levels and reduce injuries. Most of the results presented here are consistent among studies. However, there is a great scarcity of research addressing flamenco movement in a more comprehensive perspective.  相似文献
