本文通过对１９９３年全国少年乒乓球比赛的各种打法类型统计及技战术特点的分析，建议：１．在打法类型的配备上应坚持“百花齐放”的战略方针，提高少年运动员的全面作战能力；２．各省市少年队及业余体校应在重视直拍快攻的前提下，着重抓好发展方向和技术风格的培养；３．加强少年运动员的心理训练。 相似文献

该文主要通过文献资料法,了解羽毛球运动中“女子打法男子化”的发展历程,对其已出现的定义、表述表示质疑。目前所说的“女子打法男子化”主要是指,女运动员进攻较为犀利、凶狠,以及在单个技术的使用上与男运动员较为相似。但是,打法类型是根据不同技战术组合而成的,基本的技战术分类没有性别之分,打法类型也没有男女之分。因此,不管女运动员的打法类型多么凶狠、单个技术的使用频率多么趋向男运动员,在说法上都不能将其打法称为“打法男子化”。在这个过程中,应尊重竞技体育的发展规律,认识到在科学的选材和训练下女运动员的整体水平在逐渐提高,不应强行将女运动员的进步与所谓的男子打法相联系。 相似文献

丁松 《上海体育学院学报》2015,(2):68-72,85
在对乒乓球削攻结合打法进行历史回顾的基础上,从乒乓球竞技训练理念、规则与器材及进攻型技术的变化等方面,梳理影响其发展的主要因素。以朱世赫为个案,对世界优秀削攻型运动员的技战术进行分析,指出削攻结合打法的发展趋势:单一的技战术已不能满足乒乓球运动发展的需要,应汲取各种打法类型的优点,使之融入削攻结合型战术体系。 相似文献

根据射击项目训练特点和个性因素,在训练中选择适合自己的打法非常重要,打法选择要根据个人的性格、胆量、反应、枪支稳定性时间长短来决定.教练员在决定运动员打法前,要认真了解运动员自身条件以决定运动员的打法,尽量少走弯路. 相似文献

通过对2007年全国跆拳道冠军赛159场比赛进行统计分析,结果表明：各种腿法在跆拳道比赛中的运用,横踢是核心技术,特别是后横踢是得分的主要手段,其得分率占85％以上,拳法得分依然为零,因此应加强拳法得分能力的培养;男子运动员对高难度击头腿法的得分均优于女子运动员,说明我国女子运动员对高难度击头技术的掌握不如男子运动员;在本次比赛中采用防守反击打法的运动员占多数,以稳求胜。 相似文献

中国足球"黑哨"现象的人性成因 总被引：2，自引：0，他引：2
从人性的角度对中国职业足球联赛中“黑哨”行为产生的原因进行探讨。趋利自保是人的本性,在一般情况下,人总是在追求自身利益的最大化。然而,当人对利益的追求超出一定限度时就会产生非理性的行为,最终导致人本质向恶的异化,人变得贪婪、腐败甚至走向毁灭。“黑哨”就是职业足球联赛中各利益主体为追逐自身最大的利益,在法规制度、道德约束不够的地方,违背了人的道德本质,以权谋私,为满足自己的私欲,置国家和他人利益于不顾而做出的不道德行为。从防范人本质异化的方面考虑,对防范“黑哨”行为的发生,应加大防范力度,重在治本;并加大查处力度,惩戒于后。 相似文献

This study investigated factors that enhanced and constrained the career development of six teachers, who had graduated from the same university teacher education program, in their induction years (Woods & Earls, 1995) and again later in their career cycles. Three participants were physical education teachers (PETs), and three were former physical education teachers (FPETs). Fessler's (1985) Teacher Career Stage Model provided the theoretical framework. Data sources were: interviews with teachers and their teacher educators and direct observations of lessons. Results indicated that the PETs continued to have skill development as their primary teaching objective. The teachers maintained many of their teaching skills, and shifted between the career cycles of "competency building" and "enthusiastic and growing." All three FPETs left their physical education positions during the career frustration stage and at the time of publication were in the career exit stage. 相似文献

The effectiveness of pre-performance routines on skilled performance in a self-paced skill has yet to be verified. In this study, we examine the importance of temporal and behavioural consistency in these routines. The duration and specific pattern of behaviours exhibited before each free throw (n = 284) were observed during 14 National Basketball Association play-off games. An intra-individual standardized score was calculated for each shot's duration. Each player's dominant behavioural routine was identified and each shot was classified as "sequence followed" or "sequence not followed". No difference was observed in the success rates of shots associated with brief, long, and regular duration routines (P > 0.05). However, players were more successful when they followed their dominant behavioural sequence (83.77% success) than when they deviated from their specific behavioural pattern (71.43% success) (P < 0.05). The findings are interpreted in light of relevant theory and implications for practice are discussed. 相似文献

Irwin G Kerwin DG 《Sports biomechanics / International Society of Biomechanics in Sports》2007,6(2):131-144
This study focused on identifying the most effective skill progression for developing the longswing on high bar in men's artistic gymnastics. Building on previous work by Irwin and Kerwin, in which a method to rank progressions based on their angular kinematics was developed, this study aimed to use the method to quantify similarities in inter-segmental coordination between selected progressions and the longswing on high bar. Video images of four members of the UK men's national gymnastics squad performing three series of five longswings and eight progressions were recorded at 50Hz. Two-dimensional direct linear transformation techniques were used to determine the real-world coordinates from the digitized data. Inter-segmental coordination of the hip and shoulder joints during the functional phases of the longswing was assessed using continuous relative phase. Similarity between the longswing and each progression was represented by a "specificity score", which was also used to rank the progressions. Each progression's specificity score was calculated by combining a "difference score" (root mean squared difference between the continuous relative phase profiles of the longswing and the progression) and a "variability score" (standard deviation of the continuous relative phase profiles for each progression). The progressions that were most similar to the longswing included the looped bar longswing and layaway swing down (ranked 1st and 2nd), with specificity scores of 9% and 10% respectively. In contrast, the least similar progressions were the looped bar "no action" longswing (51%) and pendulum swing (63%) (ranked 7th and 8th). Establishing effective skill learning pathways is recognized as a key component of the coaching process and ranking progressions based on their specificity score provided a mechanism to identify progressions with similar inter-segmental coordination profiles to the key skill on the high bar, the longswing. 相似文献

目的:探索有氧运动和抗阻运动两种常见运动方式对非酒精性脂肪肝病(NAFLD)患者内脏脂肪、肝功能与脂代谢治疗效果对比,为患者选择适宜的运动方案提供依据。方法:检索PubMed、Web of Science、中国知网等数据库,搜集随机对照试验文献,采用Cochrane偏倚风险评估文献质量,Review Manager 5.3软件meta分析。结果:1)内脏脂肪与脂代谢方面,有氧运动与抗阻运动之间的疗效差异不具有统计学意义;2)肝功能方面,肝功能天冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)与氨酰转移酶(GGT)在两种运动间的疗效差异不具有统计学意义;进一步亚组分析显示,有氧运动对AST在“年龄<52岁”、“BMI≥28”、“干预频次为3次/周”、“干预周期≤12周”亚组中改善效果比抗阻运动好;对ALT的改善在“BMI≥28”、“干预频次为3次/周”亚组中效果更佳。结论:有氧运动与抗阻运动相比,对NAFLD患者内脏脂肪、肝功能与脂代谢治疗效果均无差异,两种运动方式的干预效果相近;但不同亚组仍表现出差异,有氧运动组AST在低龄、高BMI、短干预周期和短干预频次组改善效果更佳,ALT在低龄、短干预周期组具有更好效果。提示患者应根据自身心肺功能、肌肉力量及自身运动情况等,选择适宜自己的运动进行,而当患者需要改善AST与ALT时,建议选择有氧运动干预方式。 相似文献
