通过对中国男子篮球联赛(CBA)运动员在比赛中的跑动及负荷情况研究揭示篮球运动员比赛中跑动负荷的特点和规律,为篮球项目科学地制定训练计划,实施科学化训练提供依据。研究采用文献资料、录像分析、观察、统计等研究方法,采用德国SIMIscout技战术分析软件,系统量化了篮球运动员在比赛条件下的跑动能力、不同位置篮球运动员跑动区域位置点分布情况、不同位置篮球运动员在不同跑动速度下的跑动距离特征等。结论表明:篮球比赛是以无氧和有氧混合供能为主,但主要是中低等强度的有氧供能为主占75%左右,高强度及冲刺跑所占比例较少不到10%。从无氧高强度跑动距离阶段来看,也是中锋占比例最少,其次是前锋和后卫,说明篮球比赛的前锋和后卫队员的无氧跑动能力要好于中锋。从运动员比赛活动范围看,前锋运动员活动范围较大,基本是在整个前场范围内跑动;中锋运动员在攻防两端跑动范围基本上都在3分区以内、3 s区弧顶和篮下范围内;后卫运动员的跑动范围也比较大,进攻时主要是接近3分线以外范围内活动。 相似文献

探究足球比赛中控球率不同时,对球员体能和技术表现的需要及影响,对球队制定训练计划有着积极的参考意义。数据的获得是借助多台
高速摄像机、计算机追踪系统。研究表明：在不同控球率的比赛中,体能类指标中的跑动总距离和高强度跑距离没有明显区别;高控球率球队有球
高强度跑动要高于低控球率31%,而低控球率球队无球高强度跑动距离则要超出高控球率22%;高控球率队球员传球次数比低控球率队多44%,这
种优势同样体现在成功传球次数、接球次数、触球次数、射门、运球和攻入对方最后1/3防守区域次数等;中后卫在低控球率时的高强度有球跑动距
离要少于高控球率33%,而边后卫、前锋和中场队员在低控球率时,高强度无球跑动要多于高控球率同位置的队员,有球高强度跑则要低于高控球
率同样位置的球员。技术指标数据统计结果表明,在采用高控球率打法时,场上所有位置球员传球和接球的总次数要明显高于低控球率的打法。
结果表明：控球率对球队的整体跑动没有明显的影响,但对高强度跑动数据和一些技术因素的运动表现有较明显的影响;球队控球率不同时,特定
位置球员的跑动和技术指标会产生明显的变化。 相似文献

男子曲棍球运动员比赛跑动能力研究 总被引：1，自引：0，他引：1
运用SIMI°Scout技、战术分析系统对63名参加第11届全运会曲棍球比赛的男子曲棍球运动员的比赛跑动能力进行分析,在不划分位置情况下,曲棍球运动员上半场多数速度段跑动距离和跑动总距离高于下半场多数速度段跑动距离,表明下半场由于体能下降导致多数速度段的跑动距离有所下降。经过t检验发现,曲棍球的第1速度段跑动距离上、下半场有显著性差异,说明曲棍球第1速度段的跑动距离在下半场下降更明显。在划分运动员位置情况下,量化了曲棍球前锋运动员、前卫运动员和后卫运动员不同时间段的不同速度段的跑动距离。通过对比发现,曲棍球比赛中,运动员跑动距离存在显著的位置特征,前锋运动员和前卫运动员无氧高强度和无氧有氧混合中等强度跑动和跑动总距离要高于后卫运动员。前锋运动员、前卫运动员和后卫运动员上半场多数速度段的跑动距离和跑动总距离高于下半场多数速度段的跑动距离,通过t检验没有发现更进一步的差异性。 相似文献

Match performance of high-standard soccer players with special reference to development of fatigue 总被引：16，自引：2，他引：14
The aim of this study was to assess physical fitness, match performance and development of fatigue during competitive matches at two high standards of professional soccer. Computerized time-motion analyses were performed 2-7 times during the competitive season on 18 top-class and 24 moderate professional soccer players. In addition, the players performed the Yo-Yo intermittent recovery test. The top-class players performed 28 and 58% more (P < 0.05) high-intensity running and sprinting, respectively, than the moderate players (2.43 +/- 0.14 vs 1.90 +/- 0.12 km and 0.65 +/- 0.06 vs 0.41 +/- 0.03 km, respectively). The top-class players were better (11%; P < 0.05) on the Yo-Yo intermittent recovery test than the moderate players (2.26 +/- 0.08 vs 2.04 +/- 0.06 km, respectively). The amount of high-intensity running, independent of competitive standard and playing position, was lower (35-45%; P < 0.05) in the last than in the first 15 min of the game. After the 5-min period during which the amount of high-intensity running peaked, performance was reduced (P < 0.05) by 12% in the following 5 min compared with the game average. Substitute players (n = 13) covered 25% more (P < 0.05) ground during the final 15 min of high-intensity running than the other players. The coefficient of variation in high-intensity running was 9.2% between successive matches, whereas it was 24.8% between different stages of the season. Total distance covered and the distance covered in high-intensity running were higher (P < 0.05) for midfield players, full-backs and attackers than for defenders. Attackers and full-backs covered a greater (P < 0.05) distance in sprinting than midfield players and defenders. The midfield players and full-backs covered a greater (P < 0.05) distance than attackers and defenders in the Yo-Yo intermittent recovery test (2.23 +/- 0.10 and 2.21 +/- 0.04 vs 1.99 +/- 0.11 and 1.91 +/- 0.12 km, respectively). The results show that: (1) top-class soccer players performed more high-intensity running during a game and were better at the Yo-Yo test than moderate professional players; (2) fatigue occurred towards the end of matches as well as temporarily during the game, independently of competitive standard and of team position; (3) defenders covered a shorter distance in high-intensity running than players in other playing positions; (4) defenders and attackers had a poorer Yo-Yo intermittent recovery test performance than midfielders and full-backs; and (5) large seasonal changes were observed in physical performance during matches. 相似文献

Heart rates were monitored and time-motion analysis performed for 10 players (mean age 25.6 years, s = 2.5; body mass 73.8 kg, s = 5.7 kg; height 1.75 m, s = 0.06) during four competitive futsal matches. Mean heart rate during the match was 90% (s = 2) of maximum heart rate. Heart rate records were classified based on the percentage of time spent in three zones (>85%, 85-65%, and <65% maximum heart rate); players spent 83%, 16%, and 0.3% in these three zones, respectively. During the second period, there was a significant reduction (P < 0.01) in the percentage of time spent at an intensity above 85% of maximum heart rate (first vs. second period: 86% vs. 79%). Players' movements were classified as standing, walking, jogging, medium-intensity running, high-intensity running, and sprinting (maximal speed running). Time-motion analysis indicated that the mean distance covered per minute of play was 117.3 m (s = 11.6), of which 28.5% (s = 2.2) was covered while performing medium-intensity running, 13.7% (s = 2) during high-intensity running, and 8.9% (s=3.4) while sprinting. From the results, we conclude that futsal is a multiple-sprints sport in which there are more high-intensity phases than in soccer and other intermittent sports. 相似文献

The use of GPS to evaluate activity profiles of elite women hockey players during match-play 总被引：1，自引：1，他引：0
The aim of the study was to assess the match-play activity patterns of elite women field-hockey players using a global positioning system (SPI Elite, GPSports, Fyshwick, Australia). The activity of 25 players was analysed for 13 international matches, totalling 158 player-match analyses. Overall mean playing time was 48 ± 4 min but this varied according to playing position (defenders: 56 ± 11 min; midfielders: 50 ± 10 min; forwards: 38 ± 7 min; P < 0.001, d = 0.57-1.92). In total, 55.5 ± 6.3% of match time was spent performing low-intensity exercise (standing: 5.8 ± 2.7%; walking: 49.7 ± 5.6%). Moderate-intensity exercise accounted for 38.1 ± 5.0% (jogging: 25.8 ± 3.5%; running: 12.3 ± 2.9%) of player match-time, with the remainder made up of high-intensity exercise (fast running: 4.9 ± 1.4%; sprinting: 1.5 ± 0.6%). Forwards spent more time performing moderate- (41.4%) and high-intensity (7.7%) exercise than defenders and midfield players (P < 0.001). This is the first study to use a global positioning system to assess the activity characteristics of elite female hockey players and demonstrate that these characteristics differ according to playing position. These differences are probably attributable to the ways in which substitution of players occurs. 相似文献

AbstractThe aims of this study were to: (1) quantify match running performance in 5-min periods to determine if players fatigue or modulate high-intensity running according to a pacing strategy, and (2) examine factors impacting high-intensity running such as score line, match importance and the introduction of substitutes. All players were analysed using a computerised tracking system. Maintaining ‘high’ levels of activity in the first half resulted in a 12% reduction (P < 0.01) in the second half for high-intensity running (effect size [ES]: 0.8), while no changes were observed in ‘moderate’ and ‘low’ groups (ES: 0.0–0.2). The ‘high’ group covered less (P < 0.01) high-intensity running in the initial 10-min of the second versus first half (ES: 0.6–0.7), but this was not observed in ‘moderate’ and ‘low’ groups (ES: 0.2–0.4). After the most intense periods, players demonstrated an 8% drop in high-intensity running (P < 0.05) compared to the match average (ES: 0.2) and this persisted for 5-min before recovering. Players covered similar high-intensity running distances in matches with differing score lines but position-specific trends indicated central defenders covered 17% less (P < 0.01) and attackers 15% more high-intensity running during matches that were heavily won versus lost (ES: 0.9). High-intensity running distances were comparable in matches of differing importance, but between-half trends indicated that only declines (P < 0.01) occurred in the second half of critical matches (ES: 0.2). Substitutes covered 15% more (P < 0.01) high-intensity running versus the same time period when completing a full match (ES: 0.5). The data demonstrate that high-intensity running in the second half is impacted by the activity of the first half and is reduced for 5-min after intense periods. High-intensity running is also influenced by score line and substitutions but not match importance. More research is warranted to establish if fluctuations in match running performance are primarily a consequence of fatigue, pacing or tactical and situational influences. 相似文献

This study investigated the effects of successive matches on match-running in elite under-23 soccer players during an international tournament. Match-running data was collected using a semi-automated multi-camera tracking system during an international under-23 tournament from all participating outfield players. Players who played 100% of all group stage matches were included (3 matches separated by 72 h, n = 44). Differences in match-running performance between matches were identified using a generalised linear mixed model. There were no clear effects for total, walking, jogging, running, high-speed running and sprinting distance between matches 1 and 3 (effect size (ES); ?0.32 to 0.05). Positional analysis found that sprint distance was largely maintained from matches 1 to 3 across all positions. Attackers had a moderate decrease in total, jogging and running distance between matches 1 and 3 (ES; ?0.72 to ?0.66). Classifying players as increasers or decreasers in match-running revealed that match-running changes are susceptible to individual differences. Sprint performance appears to be maintained over successive matches regardless of playing position. However, reductions in other match-running categories vary between positions. Changes in match-running over successive matches affect individuals differently; thus, players should be monitored on an individual basis. 相似文献

Physiological demands of top-class soccer refereeing in relation to physical capacity: effect of intense intermittent exercise training. 总被引：1，自引：1，他引：0
To examine the activity profile and physiological demands of top-class soccer refereeing, we performed computerized time-motion analyses and measured the heart rate and blood lactate concentration of 27 referees during 43 competitive matches in the two top Danish leagues. To relate match performance to physical capacity and training, several physiological tests were performed before and after intermittent exercise training. Total distance covered was 10.07+/-0.13 km (mean +/- s(x)), of which 1.67+/-0.08 km was high-intensity running. High-intensity running and backwards running decreased (P < 0.05) in the second half. Mean heart rate was 162+/-2 beats min(-1) (85+/-1% of maximal heart rate) and the mean blood lactate concentration was 4.9+/-0.3 (range 1.7-14.0) mmol x l(-1). The amount of high-intensity running during a match was related to the Yo-Yo intermittent recovery test (r2 = 0.57; P<0.05) and the 12 min run (r2 = 0.21; P<0.05). After intermittent training (n = 8), distance covered during high-intensity running was greater (2.06+/-0.13 vs 1.69+/-0.08 km; P< 0.05) and mean heart rate was lower (159+/-1 vs 164+/-2 beats x min(-1); P< 0.05) than before training. The results of the present study demonstrate that: (1) top-class soccer referees have significant aerobic energy expenditure throughout a game and episodes of considerable anaerobic energy turnover; (2) the ability to perform high-intensity running is reduced towards the end of matches; (3) the Yo-Yo intermittent recovery test can be used to evaluate referees' match performance; and (4) intense intermittent exercise training improves referees' performance capacity during a game. 相似文献

To relate match performance to physical capacity and training, several physiological tests were performed before and after intermittent exercise training. Total distance covered was 10.07 - 0.13 km (mean - s x ), of which 1.67 - 0.08 km was high-intensity running. High-intensity running and backwards running decreased (P ? 0.05) in the second half. Mean heart rate was 162 - 2 beats· min -1 (85 - 1% of maximal heart rate) and the mean blood lactate concentration was 4.9 - 0.3 (range 1.7-14.0) mmol·l -1 .
