The ability to recognize patterns of play is fundamental to performance in team sports. While typically assumed to be domain-specific, pattern recognition skills may transfer from one sport to another if similarities exist in the perceptual features and their relations and/or the strategies used to encode and retrieve relevant information. A transfer paradigm was employed to compare skilled and less skilled soccer, field hockey and volleyball players' pattern recognition skills. Participants viewed structured and unstructured action sequences from each sport, half of which were randomly represented with clips not previously seen. The task was to identify previously viewed action sequences quickly and accurately. Transfer of pattern recognition skill was dependent on the participant's skill, sport practised, nature of the task and degree of structure. The skilled soccer and hockey players were quicker than the skilled volleyball players at recognizing structured soccer and hockey action sequences. Performance differences were not observed on the structured volleyball trials between the skilled soccer, field hockey and volleyball players. The skilled field hockey and soccer players were able to transfer perceptual information or strategies between their respective sports. The less skilled participants' results were less clear. Implications for domain-specific expertise, transfer and diversity across domains are discussed. 相似文献

Volleyball has been described as an 'interval' sport with both anaerobic and aerobic components. At the higher skill levels, technical performance may be limited by physical characteristics as well as physical fitness, and performance characteristics such as speed and vertical jump. This investigation compared teams at the two uppermost levels of men's volleyball in Canada for differences in physical, physiological and performance characteristics. The subjects were members of the national (n = 15) and universiade teams (n = 24). The parameters examined included percent body fat, maximal oxygen uptake (VO2 max), anaerobic power, bench press, 20-m sprint time and vertical jumping ability. The only significant difference in physical characteristics between the two teams was in age. Despite similarities in standing and reach height, the national team players had significantly higher block (3.27 vs 3.21 m) and spike (3.43 vs 3.39 m) jumps. An evaluation of anaerobic power measures produced similar power outputs during a modified Wingate test, yet the national team members had higher scores (P less than 0.05) for spike and block jump differences as well as 20-m sprint time. The large aerobic component of elite volleyball play was supported by the high VO2 max value recorded for the national team players (56.7 vs 50.3 ml kg-1 min-1). The results suggest that either years of specific physical conditioning and playing or the selection of individuals for the national team who possess more desirable characteristics as a consequence of genetic endowment, plays a significant role in the preparation of international calibre volleyball players. 相似文献

The purpose of this study was to investigate the playing characteristics of team performance in international men's volleyball. The specific purposes were (a) to examine differences in playing characteristics (in particular, the set and spike) between the Attack Process and the Counterattack Process; (b) to examine changes in playing characteristics as a function of team success (as indicated by single-game outcomes and by final tournament standings); and (c) to determine the best predictor, or a set of predictors, of team success among the selected skill components. Seventy-two sample games from the Third Federation of International Volleyball Cup men's competition were recorded using a computerized recording system. Results showed that the significant differences between Team Standing and Game Outcome were due to better performances on those skills used in the Counterattack Process. Among the eight selected skills, the block and spike were the most important in determining team success. The methodology used in this study and the subsequent results provide valuable aids for the coach in the evaluation of team performance and ultimately in the preparation of training sessions in volleyball. 相似文献

Abstract We investigated the effect of increases in task complexity on the dual-task draw-and-pass performance of professional rugby league players. Moreover, we determined the relationship between dual-task draw-and-pass proficiency measured in isolation and draw-and-pass performances as they occurred in actual competitive matches. In Study 1, 12 rugby league players performed 2-on-1 and 3-on-2 attacking drills under single (primary skill) and dual-task (primary skill performed in conjunction with secondary-task) conditions. Reductions in draw-and-pass performance occurred when task complexity was increased from the 2-on-1 to the 3-on-2 situation. In Study 2, 58 rugby league players undertook the dual-task draw-and-pass assessment. Players then competed in National Rugby League matches with video footage coded for the number of tries scored and the activities that led to the try. A total of 303 tries were scored with 150 (49.5%) tries scored from a draw-and-pass situation. Significant associations were detected between 2-on-1 dual-task draw-and-pass performance in the isolated test condition and draw-and-pass performances in competition. These studies provide evidence of (i) the greater attentional demands of the skill of drawing-and-passing in elite team sport athletes when more players are involved and (ii) the practical utility of off-field dual-task testing in supplying information predictive of skills performance in competition. 相似文献

Abstract Junior high school boys (N=181) took part in this study. There were 91 athletes and 90 nonathletes who took five psychological function tests2 and eight sport skill tests to determine (a) whether differences existed in selected psychological functions and selected sport skills between junior high school boy athletes and nonathletes, (b) the degree of relationship between psychological functions and sport skills, (c) the implementation of a six-multiple variation equation in predicting probable individual sport skill scores, and (d) the degree of relationship between a long and short form psychological functions test and a long and short form sport skills test. The Stoelting visual reaction timer apparatus was used to test for simple reaction time. The Howard-Dolman apparatus was used to test for depth perception. The McClure perimeter was used to test for peripheral vision left eye, right eye, and total angle. The sport skill tests used were soccer combination skills and volley; basketball dribble shoot and volley; volleyball volley and serve; and baseball volley and repeat throws. Significant differences existed on all psychological function tests and sport skill tests between athletes and nonathletes, in favor of athletes. The psychological function tests were independent of each other except for peripheral vision total angle with right eye and left eye. There was a low to moderate relationship between the psychological functions and the sport skills. The six-variable multiple R regression equation had a 70 percent predictive accuracy on individual scores for each sport skill test. The short form psychological functions test and the short form sport skills test could replace their respective long forms. The short form psychological functions test could moderately predict sport skill performance in the sport skill areas selected. 相似文献

2003年世界女排大奖赛7个单项技术统计资料表明,尽管中国女排在本次大奖赛中有比较出色的发挥,取得了复赛以来的五连胜,并在与老对手俄罗斯队的决赛中,以3∶0完胜对手,首次获得世界女排大奖赛的冠军,但笔者在对本次大奖赛单项技术统计资料进行综合比较分析中发现,中国女排在扣球、拦网、防守等技术方面与世界强队仍然存在一定的差距,并提出了今后努力的方向。 相似文献

中外女排比赛中接拦回球数量仍然较多,占扣球总数的14%左右,比赛中80%左右的拦回球落在3m线前区域。中国女排接拦回球的效果好于日本女排、塞尔维亚女排和多米尼加女排,但与巴西女排、美国女排相比差距较大,同俄罗斯女排、意大利女排接拦回球的效果相差不大。接拦回球失误的主要原因有接拦回球队员反应跟不上造成无防守动作形成失误,其次是接拦回球队员防守意识不强未及时进入防守位置形成失误。中国女排应加强接拦回球跟进保护意识培养,努力提高各种倒地和单手垫球技术,从而提高接拦回球能力。 相似文献
