普通高校体育课必须重视田径教学

高校田径运动的普及、发展和学生身体素质的提高离不开田径教学，高校体育课必须重视田径教学。受学生“自主选项”等因素的影响，普通高校田径教学正面临着存亡的危机。为适应素质教育的需要，高校田径课程体系必须摆脱“技术教育”的束缚，树立“健康第一”的体育思想，建立和完善新的田径课程体系，为“终身体育”服务。     

Associations between partnership characteristics and perceived success in Dutch sport-for-health partnerships

To reach and include socially vulnerable people through sport, it is important to create partnerships between sports organisations and public health organisations (i.e., sport-for-health partnerships). Working in sport-for-health partnerships is challenging, however, and little is known about how to manage such partnerships. To explore possible predictors of successful sport-for-health partnership, the authors administered a questionnaire among 86 participants in Dutch sport-for-health partnerships. The questionnaire included measures pertaining to three indicators of successful inter-sectoral partnership (i.e., partnership synergy, partnership sustainability, and community outcomes) and nine partnership elements that may predict its success. Multivariate results suggest that (a) partnership synergy may be best predicted by communication structure and building on the partnership participants’ capacities, (b) community partnership outcomes may be best predicted by partnership visibility and task management, and (c) partnership sustainability may be best predicted by partnership visibility. Hence, the authors would recommend actors in sport-for-health partnerships to pay particular attention to communication structure, building on capacities, visibility, and task management.     

The biomechanical characteristics of high-performance endurance running

The biomechanical profile of high-level endurance runners may represent a useful model that could be used for developing training programmes designed to improve running style. This study, therefore, sought to compare the biomechanical characteristics of high-performance and recreational runners. Kinematic and kinetic measurements were taken during overground running from a cohort of 14 high-performance (8 male) and 14 recreational (8 male) runners, at four speeds ranging from 3.3 to 5.6?m?s^?1. Two-way ANOVA analysis was then used to explore group and speed effects and principal component analysis used to explore the interdependence of the tested variables. The data showed the high-performance runners to have a gait style characterised by an increased vertical velocity of the centre of mass and a flight time that was 11% longer than the recreational group. The high-performance group were also observed to adopt a forefoot strike pattern, to contact the ground with their foot closer to their body and to have a larger ankle moment. Importantly, although observed group differences were mostly independent of speed, the tested variables showed a high degree of interdependence suggesting an underlying unitary phenomenon. This is the first study to compare high-performance and recreational runners across a full range of kinematic and kinetic variables. The results suggest that high-performance runners maintain stride length with a prolonged aerial phase, rather than by landing with a more extended knee. These findings motivate future intervention studies that should investigate whether recreational runners could benefit from instruction to decrease shank inclination at foot contact.     

No effect of HMB or α-HICA supplementation on training-induced changes in body composition

β-hydroxy-β-methylbutyrate (calcium: HMB-Ca and free acid: HMB-FA) and α-hydroxyisocaproic acid (α-HICA) are leucine metabolites that have been proposed to improve body composition and strength when combined with resistance exercise training (RET). In this double-blind randomized controlled pragmatic trial, we evaluated the effects of off-the-shelf supplements: α-HICA, HMB-FA and HMB-Ca, on RET-induced changes in body composition and performance. Forty men were blocked randomized to receive α-HICA (n?=?10, fat-free mass [FFM]?=?62.0?±?7.1?kg), HMB-FA (n?=?11, FFM?=?62.7?±?10.5?kg), HMB-Ca (n?=?9, FFM?=?65.6?±?10.1?kg) or placebo (PLA; n?=?10, FFM?=?64.2?±?5.7?kg). The training protocol consisted of a whole-body resistance training routine, thrice weekly for 8 weeks. Body composition was assessed by dual-energy x-ray absorptiometry (DXA) and total body water (TBW) by whole-body bioimpedance spectroscopy (BIS), both at baseline and at the end of weeks 4 and 8. Time-dependent changes were observed for increase in trunk FFM (p?相似文献   

Optimizing recovery to support multi-evening cycling competition performance

Road criterium and track bicycle racing occur at high speeds, demand repeated high power outputs, last 10–90?min, and offer little chance for recovery after the event. Consecutive evenings of criterium and track racing are respectively known as speed-week or six-day events and take place in evening hours over the course of a week. Given the schedule and timing of these competitions, return to homeostasis can be compromised. No recommendations exist on how to optimize recovery for cyclists participating in these types of repeated evening competitions. Criterium and track cyclists spend considerable time, near and above the individual lactate threshold and therefore mostly utilize carbohydrate as their chief energy substrate. Henceforth, pre – and post-race nutrition and hydration is examined and recommendations are brought forward for carbohydrate, protein, and fluid intake. As evening high-intensity exercise perturbs sleep, strategies to optimize sleep are discussed and recommendations for an optimal sleep environment are given. Active recovery is examined, and the benefits of a short duration low intensity exercise reviewed. Passive recovery methods such as compression garments and cold water immersion are recommended, while evidence for massage, pneumatic compression devices, and neuromuscular electrical stimulation is still lacking. Optimizing recovery strategies will facilitate a return to the resting state following strenuous night competition.     

What is a good father? The meaning of a good father through sports parenting in South Korea

Abstract

The purpose of the current study is to uncover the meanings that constitute a good father within the context of a sports/leisure setting and to analyse how these meanings are enacted in practice. Results showed that the ‘good father’ of today, as perceived by fathers, is a multifaceted construct that is construed through their interactions with other family members. First, fathers constructed the meanings of a good father through the memories of their own fathers during their childhood. Second, fathers constructed the meanings through their relationship with their wives. They regarded sport parenting as an important practice for them to be a good husband to their wives. Finally, fathers constructed the meanings of a good father through their relationships with their children and the time spent with their children was a particularly important requirement for them to fulfil their role as a good father.

新时期中国体育外交政策探析

2018年朝鲜成功开展一次体育外交行动参加韩国平昌冬奥会,向韩国政府表达出善意的政策倾向,朝鲜半岛的紧张局势也因此得到缓解,体育外交的政治收益又一次得到验证。以新时期体育外交为研究对象,采用文献资料法、逻辑分析法研究新时期开展体育外交活动的政治诉求,如何推动中国的外交事务和体育行业的发展。研究认为：体育外交能够以相抵柔和的方式表达政治意见或者政治态度;中国优秀传统文化、中国传统体育项目需要传承和发扬光大,需要适合根据国际文化变化做出调整,更需要加强对外交流;国家领导人或者体育明星在体育外交中塑造国家形象的功能不容小觑;积极培养能够在国际体育组织任职的人员、积极参与国际体育事物能够缓解中国在体育界话语权薄弱的问题。
