运用文献资料法对"健康中国2030"背景下全民健身与全民健康深度融合发展的基本态势进行梳理，剖析深度融合的薄弱环节及解决路径。全民健身与全民健康进行深度融合的发展趋势及态势集中体现在习近平总书记关于全民健身以及全民健康的一系列重要讲话、国家政策支撑、发展成果、成果转化与应用四个方面。深度融合存在协同体制机制障碍、法律法规缺失或不完善、供需矛盾协调障碍、交叉领域专业人才不足等薄弱环节。研究建议：需从部门融合和联合设置工作小组、部门和地方政策法规融合及保持延续性、资源融合与供需两端改革、专业融合和人才融合等四条路径进行改革，全方位推进全民健身与全民健康的深度融合发展。 相似文献

新校园足球竞赛体系已初具雏形，建成特点鲜明的校内外四级联赛体系。竞赛组织处于体育、教育部门"双轨制"主导局面。竞赛目标从"足球后备人才培养"演化为"夯实中国足球持续健康发展的人才基础"。赛事系统呈现出明显的学段差异。赛事相关的资源配置亟待提升。当前我国校园足球竞赛体系面临政策发展不统筹、人才供应链不配套、校园与职业赛事阻塞、竞赛保障资源配置不足、赛事监督评价落后的困局，竞赛体系整体正处在由"做大"到"做强"的十字路口。在由"基础建设"到"内涵发展"理念指导下，提出具体治理路径。政策治理层面：统筹竞技普及，发挥政府引导整合作用；人才流通层面：构建选拔机制，畅通各学段人才供应链；跨域融合层面：突破体制屏障，衔接职业足球竞赛体系；资源保障层面：调动多元参与，加强竞赛保障体系建设；监督治理层面：运用智慧监管，推进监督评价的科学化。 相似文献

ABSTRACT This study aimed to examine the effects of two jump squat (JS) training programs involving different loading ranges in under-20 soccer players during a preseason period. Twenty-three elite young soccer players performed sprint speed (at 5-, 10-, and 20-m), change-of-direction (COD) speed, JS peak-power (PP), and countermovement jump (CMJ) tests pre and post four weeks of training. Athletes were pair-matched in two groups according to their optimum power loads (OPL) as follows: lower than OPL (LOPL; athletes who trained at a load 20% lower than the OPL) and higher than OPL (HOPL; athletes who trained at a load 20% higher than the OPL). Magnitude-based inferences were used to compare pre- and post-training measures. Meaningful increases in the PP JS were observed for both groups. Likely and possible improvements were observed in the 5- and 10-m sprint velocity in the LOPL group. Meanwhile, possible and likely improvements were observed in the CMJ, 5- and 10-m sprint velocity, and COD speed in the HOPL group. Overall, both training schemes induced positive changes in athletic performance. Soccer coaches and sport scientists can implement the JS OPL-based training schemes presented here, either separately or combined, to improve the physical performance of youth soccer players. 相似文献

运用文献研究法、饱和经验法、典型案例分析法对苏、浙、沪三省市地方足球协会进行实证研究，依据软法制定主体和实施主体的不同，提炼概括了当前地方足球协会的两种软法治理模式，即省级层面地方足球协会"政府主导型"软法治理模式和市级层面地方足球协会"多维互动型"软法治理模式，并对这两种模式的特征进行比较分析。继而归纳了当前地方足球协会软法治理"程序缺失、责任制度不规范、承诺滞后和权利救济缺失"的四个困境，从"内部法人治理结构、相关主体法治观念、软法的程序、监督问责机制"四个方面阐释了产生软法治理困境的原因，最后提出四项地方足协软法治理的对策建议。 相似文献

ABSTRACT
The aim of this study was to compare the effects of 20 min neuromuscular training with a programme of 10 min in youth football players. 342 (15.4 ± 1.7 years) male football players from 18 teams were included, and cluster-randomized by team into two intervention groups. Both groups performed an injury prevention programme twice a week over five months using the same exercises but a different duration. The first intervention group (INT10, n = 175) performed the programme for 10 min, the second intervention group (INT20, n = 167) for 20 min. Primary outcomes were lower extremity (LE) injuries. Secondary outcomes were injury type, severity, mechanism and compliance to the intervention. 13 teams with 185 players were included for final analysis. No significant group difference was found between INT10 (6.37 per 1000 h) and INT20 (7.20 per 1000 h) for the incidence rate ratio of the lower extremities (IRR = 1.03, 95% confidence interval 0.59, 1.79), nor for the distribution of injury location, type, severity or mechanism. The results show that performing preventive exercises for 10 min is no less effective than 20 min in youth football players. Shorter training sessions can, therefore, be effectively used for injury prevention. 相似文献

Pechstein案和Mutu案是近年来体育法学界广受关注的重大体育纠纷案件。两个案件都是案情复杂、时间跨度较大、所涉法律问题较多、经历了诸多诉讼程序的案件,最后都提交至欧洲人权法院审理。欧洲人权法院对Pechstein案和Mutu案的判决使得该案对国际体育法治的影响更为深远。运用文献资料法、比较法、案例分析法等方法,基于Pechstein案和Mutu案各审理机构的裁决分析,对Pechstein案和Mutu案的案情、各审理机构的裁决进行了全景式的梳理和分析,并就欧洲人权法院的判决依据进行了深入的研究。最后,就欧洲人权法院对Pechstein案和Mutu案的裁决对CAS的改革、体育仲裁的完善、体育特殊性等问题进行了分析和讨论,并对Pechstein案和Mutu案给中国体育法治建设、体育仲裁制度建立带来的启示进行了分析。 相似文献

Recent theories suggest that negative effects of fatigue on performance are determined by perception of effort and motivation rather than being directly caused by reaching physiological limits. In the current experiment, the influence of motivation on fatigue-induced decrements in soccer performance was experimentally investigated. Sixty amateur soccer players performed a validated soccer-passing test before and after a fatigue protocol. Results showed that players’ motivation and performance decreased after the fatigue protocol for players in the control group. In contrast, players in the motivation group (i.e., with motivation experimentally induced after the fatigue protocol) were able to uphold their motivation and increase their performance. These results indicate that motivation plays a crucial role in performance under fatigue, as fatigue-induced decrements in soccer passing performance can be counteracted by high levels of motivation. Future research may explore the limits of this counteracting effect and extend findings to other relevant performance aspects. 相似文献

职业裁判制度是足球职业化发展到一定阶段的必然产物，其引入将有力提升我国裁判执法水平，助推我国足球事业发展。认为，职业裁判是职业联赛健康发展的关键力量，是足球运动技术发展的客观要求，是提升足球裁判整体水平、统一集中管理的需要。目前，我国的足球裁判存在基数小、水平低、待遇低、环境差等问题。只引入足球职业裁判制度而无配套措施，可能无法解决根本矛盾；目前的国内联赛规模也还无法满足职业裁判发展需求，职业转换难度大及退休保障不足，也阻碍着我国职业足球裁判制度的实施。指出，应加快足球联赛发展，与职业裁判发展互促互进；健全体育裁判法律法规，改革职业裁判组织管理方式；建立健全职业裁判员的薪酬和退休保障体系；注重青少年裁判培养，全面提升在职裁判员业务水平。多管齐下，使足球职业裁判制度发挥更好的效果。 相似文献

Isokinetic hamstring-to-quadriceps (H:Q) ratios are frequently used to assess knee muscle strength imbalances and risk of injuries/re-injuries. The use of peak torque (PT) or total work (TW) to estimate joint stability may lead to different results because of the differences between these two neuromuscular variables. Thus, the current study aimed to compare the conventional and functional H:Q ratios calculated by PT and TW. Ninety-three male professional soccer players from Brazilian first division teams performed isokinetic concentric and eccentric contractions of the quadriceps and the hamstrings at 60°/s. Muscle strength balance was calculated using the conventional torque ratio (CTR) and conventional work ratio (CWR), functional torque ratio (FTR) and functional work ratio (FWR) were highly and moderately correlated between them (r?=?0.83 and r?=?0.73, respectively). The Wilcoxon statistical test revealed significant differences between CTR and CWR, as well as FTR and FWR (p?T-test demonstrated significant differences in mean CTR–CWR and FTR–FWR, whereas Bland–Altman plots showed non-consistent bias. In addition, the chi-square test demonstrated significant differences between players below the conventional reference values and functional reference values (p?相似文献

当前的校园足球面临着校园足球发展与"全体学生的体育发展"的矛盾、校园足球如何与其他运动项目共同发展的问题、校园足球的教学、训练、比赛等工作的协调发展等较为突出的问题。国务院办公厅文件中提出的"一校一品"、"一校多品"的体育课程教学改革在时间上形成交叉共振，但两者具体是怎样的关系缺乏讨论。"一校一品"应是学校明确确定一个最有特色的体育项目作为全体学生学习的主项，各个年级均以其为主要教学内容，技战术难度随年级递增，每个年级用1/2-2/3的时间进行该主项的教学，其他时间用于其他运动项目的"简学"的课程教学模式；而"一校多品"体育课程教学应是：在年级内打破班级上体育课为形式的选择性专项化体育教学模式。以"一校一品"和"一校多品"为核心的新足球课程教学模式的构建可以较好地解决当前校园足球的基本问题。建议校园足球的理论研究应结合"一校一品""一校多品"的课程改革趋势与要求积极进行新校园足球的课程教学模式的研究与探索，各校园足球特色学校关注并积极探索新的体育课程教学模式。 相似文献
