运用文献资料法,对国民收入、竞技体育和大众体育之间进行了协整和因果关系分析,认为,竞技体育水平的提升没有导致大众体育水平的提高,对大众体育是负面的影响,否定了提高普及说和相对独立说;国家经济的增强提高了竞技体育的水平,验证了举国体制的有效性,但竞技体育水平的增强没有提高国家经济实力,说明了以竞技体育为核心的体育产业对促进国民经济的发展是很弱的;国家经济实力的提高对大众体育没有明显的影响,同时大众身体素质的提高同样没有表现为提高国家经济实力. 相似文献

Currently, all elite high jumpers use the Fosbury Flop technique with a curved approach. This suggests that the curved approach presents some clear advantage, although there is no general agreement upon the mechanism or the mechanics. This study aimed to determine the characteristics of the approach curve and to investigate how it contributes to the generation of somersault rotation. A simple theoretical model was used to demonstrate that a tightening approach curve would change the inward lean towards the centre of the curve into outwards lean. Three-dimensional video analysis was used to record the performances of two elite male high jumpers in competition. It was found that in each case the radius of the approach curve and the inward lean angle both decreased towards the end of the approach. The amount of outward lean angular velocity generated was shown to be a major proportion of the required somersault angular velocity for a jump. It was concluded that the main advantage of a curved approach was that it resulted in the generation of somersault velocity providing the curve tightened towards the end of the approach. 相似文献

This social-historical study aims to enrich contemporary knowledge of the history of the Paralympics in modern China. In addition, the paper also seeks to understand policy and politics through the development of the Paralympics movement. To achieve these aims, a comparison and contrast between a ‘social approach’ and an ‘elite approach’ is provided in order to assess which approach is better in terms of current challenges facing Paralympic sport in China. This study adopts a qualitative approach and uses grounded theory as its research process. Interviews and archival material are used to gather information relevant to this study. Critical theories such as enlightenment theory, empowerment theory, and Hosking's critical disability theory, are then used to interpret the findings. The conclusion is that Paralympic sport in China has greatly benefited by an elite approach. However, after this approach enlightened Chinese society with modern disability theory, it is the time to move on to a social approach for the welfare of all people with disabilities in China. 相似文献

采用文献资料、数理统计、对比分析等方法，对我国优秀优秀女子跳高运动员倒三步助跑的相关参数进行归类与分析。结果表明，顾碧威倒三步与倒二步着地瞬间的助跑角度较合理，但应适当减小倒一步着地瞬间的助跑角度；最后三步助跑身体内倾角的变化趋势较合理，但倒二步助跑内倾角明显加大，导致水平速度损耗较大；倒一步和倒二步的步长大小变化较为理想，但倒三步助跑速度偏慢。 相似文献

The aim of this study was to investigate the relative influence of step length (SL) and step frequency (SF) on step velocity (SV) during the approach run of high-level long jumpers and to quantify the asymmetry of these step characteristics. Spatiotemporal data of the approach run were collected during national competition from 10 long jumpers (age 26.2 ± 4.1 years, height 1.84 ± 0.06 m, mass 72.77 ± 3.23 kg, personal best performance 7.96 ± 0.30 m). Analyses were conducted for total approach, early approach and late approach. For the total approach 4/10 athletes were SF reliant and 6/10 athletes favoured neither characteristic. At the early approach, 3/10 athletes were SF reliant and 7/10 athletes favoured neither. During late approach 2/10 athletes demonstrated SL reliance, 7/10 athletes were SF reliant and 1/10 athletes favoured neither. Four athletes displayed significant asymmetry for SL and three for SF. However, no athletes demonstrated significant asymmetry for SV indicating that the asymmetrical demands of take-off do not have a marked influence on step characteristic asymmetry, probably due to the constraints of the event. Consideration should be given to the potentially conflicting demands between limbs for individual athletes. 相似文献

Missing values are a common phenomenon in physical activity research, which has a negative impact on the quality of the data collected. The purpose of this study was to determine empirically the effectiveness of an individual information-centered (II-centered) approach in recovering step-count missing values by comparing the performance of the II-centered approach with the traditional group information-centered approach. Using pedometers, the step counts of 117 participants were measured for 21 consecutive days. A semisimulation approach was used to create a missing data set and several conditions of weekdays, weekend days, or both, were compared under each approach. Two accuracy indexes, Root Mean Square Difference and Mean Signed Difference, were used to determine the effectiveness of the recovery methods, and paired t tests were used to examine the mean differences between the original and the replacement values. The II-centered approach produced a more accurate recovery method. The impact of the findings and future research directions in recovering physical activity data are discussed. 相似文献
