在棒球比赛中，投手位置非常重要，一场比赛的胜负80％在于投手。而投手控制球能力的好与坏不只是身体素质和技术上的问题，心理素质占很大比重，因此剖析影响投手控制球能力的相关因素，以及如何运用心理调控方法和心理训练手段来提高控制球能力，对于我们教练员和运动员来讲是十分必要的。 相似文献

通过文献法、专家访谈法、数据分析法、视频分析法等方法,对2008年北京奥运会男子篮球八强比赛进行数据视频分析,并对后卫控制球、支配球相关数据进行统计,将八强主力后卫进行对比分析。研究结论如下：当今优秀后卫在技术能力和身体素质能力方面上均体现出更住全面的特点,技术方面运用更为合理,攻击性更加均衡、对比赛掌控能力更加稳定。中国队的后卫在控制球上跟其他国家相比,在推进时间和控制球时间上要多于其他七支球队,制约进攻效率。中国队主力后卫在总传球数争助攻数上成功率较低,投篮命中率低于其他七支球队。传球次数少、助攻次数少、投篮命中率低、直接影响后卫队员的进攻效果,也直接体现后卫队员在比赛中掌控局势的能力,综合分析中国队后卫队员在控制球和支配球能力方面还有待提高。 相似文献

一、控制球无论教练员、运动员尤其是裁判员准确理解控制球是非常重要的。控制球在篮球运动员的比赛中是非常重要的,攻防转化最突出一点是争夺控制球权。控制球表现在对球的控制,球是双方争夺激烈的焦点。比赛定义规则第一章,第一条明确规定:“每队的目标是将球投入对方球篮得分,并阻止对方获得控制球和得分。”因为只有控制球才有投篮得分的机会。争夺控制球是基本规律,主要表现在以下三个方面。1.非控制球队员之间攻防对抗,即接球与阻止接球之间的对抗。2.控制球队员(持球队员)与防控制球队员之间的矛盾,如持球突破、投篮、运球和传球时攻… 相似文献

女子手球守门员的选材及训练 总被引：1，自引：1，他引：0
前言凡有守门员的比赛项目(如足球、冰球、手球等),守门员往往是至关重要的队员。他们守卫着最后一道防线,每一个动作的成败都关系着全队的胜负。手球比赛的射门次数远比足球、冰球多,又是通过手的控制进行的,其控制球的能力比脚或器械控制球的能力要强,射门既灵活又多变。因此手球守门员的地位显得更重要。守门员在比赛中表现得好坏及水平高低和他(她)的身体形态、素质,心理素质和 相似文献

By manipulating stimulus variation in terms of opponent pitcher actions, this study investigated the capability of expert (n = 30) and near-expert (n = 95) professional baseball batters to adapt anticipation skill when using the video simulation temporal occlusion paradigm. Participants watched in-game footage of two pitchers, one after the other, that was temporally occluded at ball release and various points during ball flight. They were required to make a written prediction of pitch types and locations. Per cent accuracy was calculated for pitch type, for pitch location, and for type and location combined. Results indicated that experts and near-experts could adapt their anticipation to predict above guessing level across both pitchers, but adaptation to the left-handed pitcher was poorer than the right-handed pitcher. Small-to-moderate effect sizes were found in terms of superior adaptation by experts over near-experts at the ball release and early ball flight occlusion conditions. The findings of this study extend theoretical and applied knowledge of expertise in striking sports. Practical application of the instruments and findings are discussed in terms of applied researchers, practitioners and high-performance staff in professional sporting organisations. 相似文献

Abstract Over the past few years, there has been a significant increase in the performance of softball bats from the Olympics down to the recreational level. It is theorized that the introduction of composite-based material bats has been the largest contributor to the increase in batted-ball performance, which directly corresponds to a decrease in available pitcher reaction time that can lead to an increase in injury potential. To test this theory, a controlled field-test study comparing all of the different bat model types currently available was conducted. The performance of ten bat model types; two composite-based, two titanium-based, two aluminum-based multi-wall, two aluminum-based single-wall and two wood-based bats were measured using 1686 N/0.64 cm (379 lbs/0.25”) compression softballs in order to calculate available pitcher reaction times when using a specific bat model type. Over 1000 Batted-ball velocity measurements were analyzed using two calibrated radar devices and five experienced test subjects. The results of this study indicate that when titanium-based or composite-based softball bat performance results are compared to published safety studies in the sports of softball and baseball, available pitcher reaction times are unsafe, which can lead to a higher injury risk potential. The significance of this research is to provide experimental field-test data on the possible safety risks to pitchers that can be used to reduce the injury potential and promote safety awareness in the sport of softball. 相似文献

Baseball rules prohibit pitchers from intentionally throwing at batters. When a pitcher does so, however, it is common practice for a pitcher on the opposing team to retaliate by throwing at the first player of the offending team to bat the next inning, and for umpires to ignore the rule forbidding that. I argue that (1) player retaliation in the form of one for one is a better response to the initial violation than any other that is available, (2) one for one can be justified as payback and for anticipated good consequences, and (3) everyone who becomes a professional baseball player has consented to the practice. From these claims, I conclude that one for one is in the best interest of baseball, it is best if umpires follow common practice and wink at the rule forbidding it, and players cannot complain if they are told to throw at batters in certain circumstances, or are thrown at in just those circumstances. 相似文献

There is currently much debate about the safety of the sport of softball. Batted-ball speed and average pitcher reaction time are factors often used to determine safe performance. Batted-ball speed is shown to be the most important factor to consider when determining safe play. Average pitcher reaction time is explained and directly correlated to batted-ball speed. Eleven aluminum multi-wall, three aluminum single-wall and two composite softball bats were tested with mid-compression polyurethane softballs averaging 1721+/-62 N/6.4 mm to represent the relative bat-ball performance for the sport of slowpitch softball. Nine men and six women were chosen for this study out of a test group of over three hundred slowpitch softball players. On average, aluminum bat performance results were within the recommended safety limits established by the national softball associations. However, when composite bats were used, their performance results exceeded the recommended safety limits which can pose a significant safety risk. Using aluminum softball bats, batted-ball speeds ranged from 80 to 145km x h(-1) Using composite softball bats, batted-ball speeds ranged from 146 to 161 km x h(-1). The scientific relevance of this study is to provide performance information that can lead to injury prevention in the sport of softball. 相似文献

The aim of this study was to provide an in-depth analysis of the pick-off play in baseball. Ten collegiate left-handed pitchers and nine base-runners participated in this study. The pitchers were videotaped with four cameras to derive three-dimensional data while performing deliveries in the directions of first base and home plate in a laboratory setting. Deliveries were performed from flat ground. Differences between these deliveries were measured through ten selected joint and segment angles. The base-runners completed two distinct procedures in which they viewed video footage of left-handed pitchers and estimated the intended delivery direction. Base-runners were subsequently interviewed to determine the reasoning behind their decisions. The pitchers' data revealed differences between delivery types in nearly all of the selected angles (P < 0.01). The base-runners' data demonstrated that their ability to discriminate delivery types improved when allowed more viewing time per trial (P < 0.01). Additionally, commonalities exist among the base-runners' focal points on the pitcher while making decisions regarding delivery direction and the kinematic differences between deliveries in left-handed pitchers. The practical significance of these results, however, may be more difficult to interpret. 相似文献

Abstract Data were collected from ten games of Mite League Baseball (8- and 9-year-old players) under two conditions—game pitched by a regular player-pitcher and game pitched by a surrogate pitcher (team's coach). The Mann-Whitney U test was used to determine the significance of differences between the two groups on each of eleven variables. The use of surrogate pitchers produced significant reductions and increases, the direction of change depending on whether the variable concerned offensive or defensive actions. 相似文献
