体育三类型模式:一个需要重新审视的基本理论问题--兼论体育理念 总被引：8，自引：2，他引：6
体育分为竞技体育、社会体育、学校体育的模式存在不少可质疑之处。其主要问题在于：体育的核心部分是体育活动，而将体育分为这三类缺乏核心区分要素和标准。因而就其本质而言，体育三类模式不应是体育。尤其是体育活动的划分，之前所认为的三种类型体育实质是三种不同的体育理念。目前的体育三类模式将逐渐且必然走向“大体育”的整合，因为“大体育”是终身教育和终身体育的深切呼唤。是社会转型和体制转型的必然选择。也是匡正体育三分模式的实际需要。 相似文献

随着社会的发展和进步，体育应有其社会地位和学校地位。体育的服务对象不仅是专业运动员，更重要的是要为全人类的健康服务。体育科研也应深层次地研究人体运动规律，为提高运动训练的实效作严谨深入的探索。当前是体育科研发展的一个转折点，应该使体育科研由为了突破人体能力的极限为主要目的，转变为以探索人体运动规律，调动、指导所有从事体育锻炼的人们有效地锻炼。未来的体育科研是人体科学的一个重要部分，应为全人类健康服务。它具有尖端性、合作性和创造性的特征。 相似文献

ABSTRACTThere is a positive association between motor competence and physical activity in child populations. Little is known about the relative variance explained in physical activity when process- versus product-oriented approaches are used for evaluating motor competence. This study aimed to examine associations between product- and process-oriented motor competence assessments and their capability to explain variance in physical activity. Participants included 167 children between the ages of 6–9 years. The run, jump, throw and kick were assessed using process-oriented (Test of Gross Motor Development-2nd edition) and product-oriented (run time, jump distance, throw and kick speed) assessments. Physical activity was assessed via Yamax Digi-walker NL2000 pedometers. Weak to strong correlations between process and product assessments were found (range: r = ± 0.01 to ±0.81). Statistically significant correlations between process and product scores were more frequent for the kick and throw. Both product- and process-oriented assessments were poor at explaining variance in pedometer assessed physical activity. No more than 4% of variance in physical activity could be explained by a single skill, regardless of whether product or process scores were used. Continued examination of associations between process- and product-oriented assessments may provide a more holistic understanding of motor competence across developmental time. 相似文献

Abstract This paper discusses the use of generalizability theory, a flexible intraclass approach, for estimating the reliability of a motor performance task. The generalizability technique provides variance component estimates for each factor of an analysis of variance design. These variance estimates can be utilized to define a number of reliability coefficients which are dependent upon the logical or theoretical rationale for assigning variance component estimates as true score or error score variance. The second section of this paper presents a study illustrating the use of generalizability theory in estimating the reliability of a motor performance task. The purpose of this study was to determine the reliability of first-ball scores for beginning college bowlers. The facets of the generalizability study were identified as sex of the bowler, trials, and days. Three reliability coefficients, R 1 (.93), R 2 (.92), and R 3 (.84), were computed by assigning the different factors to either true score or error score variance. The performance of beginning college bowlers as measured by first-ball scores is reliable. While the information might be useful for the teacher or researcher who is interested in detecting between-subject differences in coeducational bowling classes, the primary purpose of this paper was to demonstrate the use of generalizability theory to estimate reliability coefficients for a set of motor performance test scores. 相似文献

Abstract The effects of practice and the passage of time on individual differences (true-score variance) and intra-individual variation were investigated. One hundred and twenty male university students were tested on a Koerth type pursuit rotor. One group was tested on six days spaced over a three-week period. Another group performed the same motor task two days only—test and retest being separated by an interval of three weeks. Each day of practice was the same for both groups—sixty 15-second trials separated by a 10-second intertrial rest. It was concluded that true-score variance as well as intra-individual variance tend to parallel the initial increases in performance and then stabilize in later practice. Since the true-score variance increased greatly as compared with intra-individual variance in early performance, the correlation between adjacent trials increased. The effect of the lay-off was to increase both individual differences and intra-individual variance to a substantial and statistically significant degree. 相似文献

In this study, we examined the utility of self-determination theory (Ryan & Deci, 2002) as a framework for understanding the antecedents of athlete burnout in elite New Zealand rugby union players (n=133). Perceptions of competence, autonomy, and relatedness (i.e. basic psychological needs) were hypothesized to be negatively related to burnout scores, while players classified as "high-burnouts" were predicted to report lower needs fulfilment than players with low burnout. Canonical correlation analysis indicated that relatedness was a low to moderate predictor of burnout, but players' competence and autonomy accounted for substantial portions of variance in two athlete burnout symptoms: reduced accomplishment and sport devaluation. The proportion of variance accounted for in the exhaustion dimension of athlete burnout was not substantive. Multivariate analysis of variance supported these results, as "high-burnout" players had lower competence and autonomy scores than athletes reporting low burnout symptoms. The two groups did not report significantly different relatedness scores. Implications of these results for researchers and practitioners are discussed. 相似文献

方差分析在理论上比较抽象、复杂,应用中又灵活多样,难以掌握。在体育统计教科书中,仅限于介绍方差分析的计算步骤,掩盖了方差分析的思想,局限了其应用范围,以致于方差分析不能广泛地运用于体育科研。本文运用数理统计中的理论结果,从应用的角度阐述了方差分析的真正思想,揭示了其实质,指出方差分析是按指定来源分解变异的一种技巧,并就如何运用方差分析的问题,提出了具体看法。 相似文献

This study was designed to identify correlates of change in walking for exercise. Respondents to a random sample mailed exercise survey were asked to complete a follow-up questionnaire 24 months after the first. Responses were obtained from 1,739 adults, reflecting an 86.6% return rate. Nonrespondents did not differ from respondents for baseline level of walking for exercise. Respondents overrepresented Caucasian and middle to high education (or income) adults. Residualized measures of change in walking for exercise served as the dependent variable, adjusted for baseline walking. Similarly, key independent variables, subject to change over time, were included after residualization. At both baseline and 24 months follow-up, adults walked for exercise an average of just under 1 hour per week, and 23.5% of the initially active adults ceased walking for exercise at 2 years. Multiple regression analyses explained more variance in walking for exercise among women than men. Change in dynamic variables such as friend's support and vigorous physical activity accounted for most of the explained variance. Results suggest that dynamic variables may need to be sustained to maintain walking for exercise. The limited explained variance suggests that more precise measures and additional determinants of walking for exercise need to be identified. 相似文献

The generalizability of bioimpedance measures was studied for the lying and standing postures, using generalizability theory. The test instrument was a Xitron Hydra ECF/ICF Bio-Impedance Analyzer System Model 4200 (Xitron Technologies, San Diego, CA): 50 healthy men and 50 healthy women volunteered as participants. A 2-facet, person-by-trial, completely crossed design was used, and all facets were treated as random. Data on each body posture, each fluid measurement, and each sex group were independently analyzed. The lying-posture data showed that the trial facet accounted for less than 0.03% of the total variance for extracellular fluid (ECF) and intracellular fluid (ICF). The residual accounted for less than 0.02% of the total variance for ECF and for 9.5% for males and 13.6% for females of the total variance for ICF. The standing-posture data showed that the trial facet accounted for less than 0.02% of the total variance for ECF and ICF. The residual accounted for less than 0.05% of the total variance for ECF and for 10.5% for males and 20.4% for females of the total variance for ICF. Overall, the lying posture produced more stable ECF and ICF measures, compared to the standing posture for male and female groups. 相似文献
