第18届世界杯足球赛决赛阶段各队进攻进球特征研究 总被引：4，自引：0，他引：4
通过对第18届世界杯足球赛64场比赛的139个进球特征统计发现,下半场进球数高于上半场,全场比赛结束前15min是全场比赛进球最高峰;进球方式是以脚射为主,其中,抢点直接脚射进球率最高;由中场发动组织进攻进球率最高;进球射门主要区域是罚球区;球门下部是进球入门的主要区域,尤其从球门右下角区域进球率最高;各位置进球数最多的是前锋队员;定位球进攻进球数位居各进攻形式之首;进球前经过“1”次传球配合后射门进球数最多,随运动员之间传球配合次数增多破门得分机率减小。 相似文献

第18届世界杯进球特征分析 总被引：1，自引：0，他引：1
对18届世界杯足球赛决赛阶段64场比赛142个进球情况进行分析,并与17届世界杯进球情况进行对照,发现18届世界杯进球总数有所下降,攻守均衡、防守相对更为稳固的打法占据了主流。上下半时进球比较均衡,除了在比赛的结束阶段出现进球高峰外,各个阶段的进球数量随着时间的推移呈递减趋势;进球主要区域是在2区,大禁区外到30m线区域也成为本届世界杯射门进球的重要区域;由中路配合切入发动进攻为进球主要进攻形式,定位球越来越受到各队的重视,战术水平也有较大提高;进球方式以抢点直接射门为主;进球大部分是由4次以下的传球完成的,且传球次数越少进球越多;进球数最多的是前锋队员,前卫队员的攻击性插上进攻已成为各队进球的重要手段,远射是他们主要的进球方式。 相似文献

运用录像观察统计等研究方法,对第18届世界杯足球赛的64场比赛、共147个进球(淘汰赛中打平后互罚点球的进球不计),分别从进球时间、进球区域、进球前主要进攻方式3个方面做了系统的分析。力求以进球为切入点,探讨进球前的有效进攻方式。结果显示,在比赛临近结束的15min为进球的最高峰;进球区域主要集中在罚球区内的2、3区,其次为罚球区外的6、7区;主要进攻方式为运动战的边路传中战术,其次为中路直传空当战术;定位球战术中的前场任意球配合也是破门得分的有效进攻方式之一。 相似文献

A physiotherapist is part of the multidisciplinary team in most intensive care units in Australia. Physiotherapists are primary contact practitioners and use a comprehensive multisystem assessment that includes the respiratory, cardiovascular, neurological, and musculoskeletal systems to formulate individualized treatment plans. The traditional focus of treatment has been the respiratory management of both intubated and spontaneously breathing patients. However, the emerging evidence of the longstanding physical impairment suffered by survivors of intensive care has resulted in physiotherapists re-evaluating treatment priorities to include exercise rehabilitation as a part of standard clinical practice. The goals of respiratory physiotherapy management are to promote secretion clearance, maintain or recruit lung volume, optimize oxygenation, and prevent respiratory complications in both the intubated and spontaneously breathing patient. In the intubated patient, physiotherapists commonly employ manual and ventilator hyperinflation and positioning as treatment techniques whilst in the spontaneously breathing patients there is an emphasis on mobilization. Physiotherapists predominantly use functional activities for the rehabilitation of the critically ill patient in intensive care. While variability exists between states and centers, Australian physiotherapists actively treat critically ill patients targeting interventions based upon research evidence and individualized assessment. A trend toward more emphasis on exercise rehabilitation over respiratory management is evident.Key Words: physiotherapy, intensive care 相似文献

AbstractThe aim of this study was to examine the effects of changes in maximal aerobic (MAS) and sprinting (MSS) speeds and the anaerobic reserve (ASR) on repeated-sprint performance. Two hundred and seventy highly-trained soccer players (14.5 ± 1.6 year) completed three times per season (over 5 years) a maximal incremental running test to approach MAS, a 40-m sprint with 10-m splits to assess MSS and a repeated-sprint test (10 × 30-m sprints), where best (RSb) and mean (RSm) sprint times, and percentage of speed decrement (%Dec) were calculated. ASR was calculated as MSS-MAS. While ?RSb were related to ?MSS and ?body mass (r2 = 0.42, 90%CL[0.34;0.49] for the overall multiple regression, n = 334), ?RSm was also correlated with ?MAS and ?sum of 7 skinfolds (r2 = 0.43 [0.35;0.50], n = 334). There was a small and positive association between ?%Dec and ?MAS (r2 = 0.02 [?0.07;0.11], n = 334). Substantial ?MSS and ?MAS had a predictive value of 70 and 55% for ?RSm, respectively. Finally, ?ASR per se was not predictive of ?RSm (Cohen’s = +0.8 to ?0.3 with increased ASR), but the greater magnitude of ?RSm improvement was observed when MSS, MAS and ASR increased together (0.8 vs. +0.4 with ASR increased vs. not, additionally to MSS and MAS). Low-cost field tests aimed at assessing maximal sprinting and aerobic speeds can be used to monitor ?RS performance. 相似文献

论新生活运动正当娱乐中的体育 总被引：1，自引：0，他引：1
新生活运动历时15年,涉及到了国民生活的方方面面。娱乐作为生活的重要组成部分,也受到新生活运动的影响。为了纠正社会上根深蒂固的“烟”、“赌”和“娼”等不良风气,新生活运动组织十分重视对正当娱乐的提倡,对体育尤为重视。蒋介石本人在新生活运动周年纪念大会上专门提到过体育问题。体育活动曾被作为新生活运动的年度中心工作或者工作要点来开展。虽然最后对体育的提倡没有达到十分理想的效果,但确实引导了国民的健康观念。新生活运动组织还培养了数量不多的体育人员,为近代体育的发展注入了动力。 相似文献

AbstractLateral movements like cutting are essential in many team sport disciplines. The aim of the present study was to analyse adaptations in motor control in response to task unpredictability during lateral movement execution. Twelve subjects performed lateral jumps with different landing modalities (stable, sliding or counteracting) that were either known (predictable setting) or unknown (unpredictable setting) prior to movement execution. Results revealed that regardless of the landing modality, hip joint abduction was significantly greater in the unpredictable compared to predictable setting. Furthermore, during the sliding landing modality, hip flexion decreased from 211 ± 7° to 207 ± 7° and knee flexion decreased from 26 ± 4° to 24 ± 4° at the instant of ground contact in the unpredictable compared to predictable condition. During the stable landing modality, the knee joint abduction increased from ?0.3 ± 6° to ?3 ± 6° after initial ground contact in the unpredictable compared to predictable setting. The present results support our hypothesis that pre-programmed motor activity depends on the predictability of the landing modality during lateral movements. According to its adaptation in the frontal plane and in some extent in the sagittal plane, the hip joint seems to play the major role in the modulation of the pre-programmed activity for successful lateral jump execution in an unpredictable setting. However, these kinematic adaptations are concerning since these changes were associated with higher knee abduction during the stable landing modality and therefore with possible higher risk of injury. 相似文献
