吴松录前刺后鞭组合技术特点及在比赛中的应用     

吴松录 《安徽体育科技》2010,31(1):17-23

散打是一项竞争激烈的竞技体育项目,组合技术在比赛中的运用频率和得分效果,都远大于单个技术动作,是运动员在比赛中获胜的主要手段。当前散打比赛,组合技术动作以2次和3次击打为主,以4次组合为辅。简单组合技术运用的成功率低于复杂组合技术的成功率。依靠经验选择的＂常用训练组合动作＂与实际比赛中的＂实用比赛组合＂还有较大差距,许多实用比赛组合在训练中还没有得到足够重视。以吴松录＂得意技＂——前刺后鞭组合技术特点及在比赛中的应用进行分析,希望能为散打竞赛训练理论的完善及教练员执教和运动员训练提供一定的借鉴和参考。  相似文献   

论乒乓球正手击球质量     

张哲 《湖北体育科技》2010,29(1):75-76,92

起源于英国的乒乓球在中国已经有了40多年的辉煌历史。成就中国乒乓球长盛不衰的因素除了有领导的关怀与自身艰苦奋斗的精神外,乒乓球技术自身的不断创新、突破、发展、完善也起到了重要的作用。在众多乒乓球技术就是当中最重视的,也是最重要的是正手技术能力。从发球抢攻,到全台正手单面攻,再到左推右攻、两面上手。发展到现今的突出正手能力,没有明显漏洞的战术思想体系,始终围绕着正手技术特点来制定相应的总体战术模式,由此经历了一个又一个的技术创新与完善的过程。  相似文献   

指导短跑训练两个问题的辩证思维   总被引：7，自引：2，他引：5  

张青 《广州体育学院学报》2000,20(1):94-97

旨在辨清对短跑训练的加速能力与最高速度、后蹬与前摆的关系问题,为提高我国的短跑训练提供参考。在查阅调查讯问的基础上,结合实际从理论上进行探讨,结果表明要提高最高速度水平,实际上就是要发展加速能力;加速能力差是我国短跑运动员的主要问题;要想跑得快就要加强后蹬的帝际效果,而此效果的提高来源于后蹬与前摆有效的相互作用。  相似文献   

我国优秀女子跳高运动员助跑最后一步摆动腿支撑技术特征研究     

徐刚 《吉林体育学院学报》2009,25(3):33-35

运用高速摄影与解析的方法,对我国优秀女子跳高运动员摆动腿在助跑最后一步支撑过程的技术特征过行分析,结果表明：我国优秀女子跳高运动员在摆动腿着地瞬间,身体重心距摆动腿着地点的水平距离较大,在摆动腿缓冲阶段,摆动腿膝关节缓冲幅度过大,水平速度损失较为严重,最后一步步长/身高指数较小。  相似文献   

我国优秀女子跳远运动员在起跳过程中摆动腿技术分析   总被引：1，自引：0，他引：1  

曹景川  李建英  白跃玲 《北京体育大学学报》2009,(7)

以我国第十届全运会女子跳远前6名运动员为研究对象,对她们在起跳过程中的摆动腿技术进行运动学研究,结果表明,我国优秀女子跳远运动员摆动腿在助跑最后一步支撑过程小腿支撑扇角比较大,身体重心下降较大,造成水平速度损失较大;蹬离地面时动作不充分,摆动的速度慢、幅度小。在起跳过程中,摆动腿的摆动动作对减小着地时的制动、加大动作幅度,提高起跳速度有着十分重要的作用。我国运动员在着板缓冲阶段,摆动腿蹬伸后向前摆动的时机晚,摆动不够积极,影响整个起跳动作的幅度,造成了身体重心不能快速前移。我国运动员起跳蹬伸阶段摆动腿动作不充分,摆动的速度和幅度不理想。  相似文献

Prevalence of sleep disorders and sleep problems in an elite super rugby union team     

Ian C. Dunican  Jennifer Walsh  Charles C. Higgins  Maddison J. Jones  Kathleen Maddison  John A. Caldwell 《Journal of sports sciences》2019,37(8):950-957

The aim of this study was to determine the prevalence of sleep disorders in an elite rugby union team using in-laboratory polysomnography (PSG) and sleep questionnaires. Twenty-five elite rugby union players underwent a night of PSG during the “off-season” of the Super Rugby competition to assess their sleep. Of interest were measurements that detected the presence of obstructive sleep apnea (OSA; apnea-hypopnea index ≥5 events/hr) and the presence of moderate-severe periodic leg movements during sleep (PLMs; ≥15 events/hr). Players completed sleep-related questionnaires to assess daytime sleepiness, perception of insomnia, risk of OSA, and the presence of restless legs syndrome (RLS) and underwent basic anthropometric assessments including body mass index and neck circumference. OSA was present in 24% (n=6) of players and PLMs ≥15 events/hr in 12% (n=3). Questionnaire responses showed that all players had insomnia defined subthreshold insomnia and excessive daytime sleepiness, two players were identified as being at risk for OSA and none were classified as having RLS. In conclusion, sleep disorders and excessive sleepiness are common in elite rugby union players. A process to identify and manage sleep disorders should be considered by teams to optimise their physical recovery, athletic performance and to safeguard their health.  相似文献   

Overall indexes of coordination in front crawl swimming     

Bruno Mezêncio  João Pedro Pinho  Rudolf Huebner  João Paulo Vilas-Boas  Alberto Carlos Amadio  Julio Cerca Serrão 《Journal of sports sciences》2020,38(8):910-917

ABSTRACT

The aim of this study was to propose a group of parameters able to quantify not only arm coordination but also inter limb coordination. These include the well know index of coordination with the relative duration of the stroke phases and two new parameters: the Index of synchronization (Ids) between arms and legs actions; and the Index of inter limb coordination (IdIC) calculated as the relative foot position during successive arm stroke phases. These parameters were compared between experts and amateur swimmers in a maximal front crawl sprint. The influence of arm stroke in leg kick parameters was also assessed, comparing the full stroke condition with a condition without arms actions. Sixty-five per cent of expert swimmers used synchronized limb actions while 95% of amateur swimmers used non-synchronized limb motions. These synchronized expert swimmers also converged towards a specific coordination pattern between foot position and arm stroke phases. In the condition without arms, both groups changed kick rate and amplitude. The present study reveals the interdependency of arms and legs actions and the importance of coordination and synchronization between limbs. Therefore, the proposed group of overall indexes of coordination provides a more complete marker for the analysis of swimming technique.  相似文献
