通过对我国九运会、2002年全国女子手球锦标赛及第15届世界女子手球锦标赛前8名队常规技术指标与比赛名次的相关分析,旨在探讨影响女子手球比赛名次的相关因素.研究表明,守门员封挡率、防守成功率、总失分、总射门成功率、助攻等指标在国内和/或国际比赛中对名次影响较大.认为,同一技术指标在不同的比赛中对名次的影响有所不同,反映出不同比赛的水平和特点,我国女子手球应提高防守水平和控制球能力,以尽快缩小与世界强队的差距. 相似文献

Abstract This study examines the differences between expert and novice team-handball players in their sensitivity to instructions that emphasize speed or precision requirements. The effects of instructions on throwing speed and accuracy of a handball over arm throw and the speed–accuracy trade-off in experts and novices is revisited. An expert group (n=18) with a training experience of more than 10 years, and a novice group (n=24) without experience in team-handball, took part in the study. The participants were asked to throw to targets located at different positions following instructions emphasizing accuracy and instructions emphasizing accuracy and speed. Throwing speed was measured with a speed gun radar, and the centre of the ball when the ball entered the goal was digitalized for accuracy. Under these experimental conditions, the novice group was sensitive to instructions for reducing throwing speed and increasing accuracy when instructions emphasized accuracy. The expert group increased throwing speed when the instructions emphasized speed, but was not less accurate. The results indicate that it is advisable for experts’ speed to be close to maximum speed since it does not seem to have a significant effect on accuracy of the throw. 相似文献

为了研究女子手球能量代谢特点,以中国队正式比赛为研究对象,分析6名中国女子手球运动员能量代谢特征。在实验室测试了最大摄氧量、无氧阈、最大心率、体重,在比赛现场测试比赛时的心率变化、血乳酸。结果:场上队员比赛平均时间为46.25 min;比赛最大心率平均为181.6次/min(177~188次/min),达到99.6%(98.9%~100.6%)HRmax,比赛平均心率为(154±10)次/min,102%(97.9~107.3%)HR-AT;心率变化振幅平均为16.8次/min;场上运动员在MHI心率区间运动时间比例最高,为47.6%,MAX区间达到17.68%,LMI区间达到16.9%,LI区间达到15.14%,L区间达到2.62%。全场赛后乳酸(3.7±1.4)mmol/L。守门员比赛最大心率158次/分,达83.6%HRmax,全场比赛平均心率125次/min,达83.3%HR-AT,全场结束乳酸1.9 mmol/L。结论:手球比赛是混氧运动,场上队员平均强度在无氧阈强度上下,运动员赛后乳酸水平较低,主要进行有氧运动,但无氧运动占一定比例,负荷强度可达自身极限。守门员比赛时心率与场上队员相比较低。研究认为,优秀手球运动员须具备高水平无氧爆发力和较强的有氧能力。无氧供能水平低,可能限制队员水平发挥。 相似文献

观察国家优秀手球运动员在递增负荷运动过程中肺通气机能变化,结果发现,运动负荷开始阶段,VERF和TV大幅增长;随着运动负荷的增加,VE、RF和TV出现相对缓慢的增长;大运动负荷期间,VE先发生上升,然后缓慢增长,RF变化与VE相似;通气阈出现在第9min左右;在开始阶段,VE/VO2随着运动负荷的增加而降低,然后,随着运动负荷增加而增加。结论：递增负荷过程中,优秀手球运动员肺通气变化过程分为快速增长阶段、缓慢增长阶段和快速增长平台期。 相似文献

In Australian football (AF), handballing proficiently with both the preferred and non-preferred arm is important at elite levels; yet, little information is available for handballing on the non-preferred arm. This study compared preferred and non-preferred arm handballing techniques. Optotrak Certus (100 Hz) collected three-dimensional data for 19 elite AF players performing handballs with the preferred and non-preferred arms. Position data, range of motion (ROM), and linear and angular velocities were collected and compared between preferred and non-preferred arms using dependent t-tests. The preferred arm exhibited significantly greater forearm and humerus ROM and angular velocity and significantly greater shoulder angular velocity at ball contact compared to the non-preferred arm. In addition, the preferred arm produced a significantly greater range of lateral bend and maximum lower-trunk speed, maximum strike-side hip speed and hand speed at ball contact than the non-preferred arm. The non-preferred arm exhibited a significantly greater shoulder angle and lower- and upper-trunk orientation angle, but significantly lower support-elbow angle, trunk ROM, and trunk rotation velocity compared to the preferred arm. Reduced ROM and angular velocities found in non-preferred arm handballs indicates a reduction in the degrees of freedom and a less developed skill. Findings have implication for development of handballing on the non-preferred arm. 相似文献

Background: Advances in technology have changed children’s lifestyle so much that the majority of them do not meet the recommended 60 min of moderate to vigorous physical activity every day. Compulsory Physical Education has been highlighted as an ideal context to achieve the suggested physical activity (PA) goals, since it could be the only place where some students become truly physically active. In those classes, the teacher selects a pedagogical approach and this selection could be vital to meet the advised PA levels.Purpose: The goal was to assess the effects of two instructional approaches, Sport Education Model (SEM) and Direct Instruction (DI) in Primary Education students’ physical activity intensity levels, game performance, and friendship goals.Method: A total of 88 students with an average age of 11.16?±?0.63 years, enrolled in two year-5 (from 10 to11 years) and two year-6 (from 11 to 12 years) Physical Education classes of the same school agreed to participate. The number of participants in the SEM was 47 and in DI was 41. The schools’ administration distributed one class of each grade to the experimental group, which experienced SEM, and to the non-equivalent group, which experienced DI. The content selected for both study groups was the same: Handball. Both study groups experienced a 15-session learning unit (45 min per class, three sessions per week). The goal was to conduct the experiment in a non-manipulated (intact) educational context. It followed a pre-test, post-test, experimental, non-equivalent group design. Participants wore Actigraph GT3X accelerometers in order to monitor physical activity levels, answered questionnaires to assess friendship goals, and their game performance was assessed using the Game Performance Assessment instrument (GPAI).Results: Results showed that students who experienced the SEM had significantly higher light and moderate physical activity levels, friendship-approach and friendship-avoidance goals, while the ones who experienced DI had significantly higher sedentary physical activity levels. The GPAI scores showed significant gains in students’ game performance in both study groups, but these were larger in the SEM one.Conclusions: The SEM could be considered more effective than DI to improve Primary Education students’ PA levels, game performance and friendship goals. 相似文献
