目的：考虑比赛中断因素影响的情况下，探讨我国职业足球运动员比赛结束时段跑动能力是否下降。方法：基于STATS Pro R计算机视频跟踪系统采集的275名职业足球运动员3 438组比赛跑动数据，围绕足球比赛间歇性特征，同时考虑中断时间动态特征和比分差距大小对跑动表现的影响。运用数据级数推断分别界定我国职业足球运动员半场结束时段和比赛结束时段的跑动能力是否下降。研究发现：(1)相较比赛开始阶段，比赛结束时段的中断时间呈现清晰的增加，比分均衡比赛结束时段的中断时间增加更为明显；(2)我国职业足球运动员比赛结束时段总跑动距离呈现清晰的下降(ES=0.31~0.56)，但该下降以中、低速跑动距离为主，所有位置运动员冲刺跑动距离均只出现微小无意义变化(ES=0.14~0.08)；(3)上半场中、低速跑动距离下降程度大于下半场，高强度跑动距离的下降程度小于下半场；(4)比赛结束时段跑动表现变化的位置特征表现为，中后场运动员高强度跑动距离未发生有意义变化，前场运动员高速跑动距离则呈现清晰的减少(ES=0.25~0.37)。结果表明：考虑比赛中断因素影响后，我国职业足球运动员比赛结束时段高强度跑动距离总体未呈现下降趋势；中后场运动员高速跑动距离和冲刺跑动距离均只出现了微小无意义变化，而前场运动员的高速跑动距离则呈现清晰的减少。 相似文献

五体球是一项集足球和篮球玩法于一体的新型球类运动,因其较高的场地利用率和观赏性而具备广阔的推广前景,目前广东省已成功举办 4.届大学生五体球联赛。采取心率监测系统和GPS全球定位系统对5 1.名大学生运动员在第三届大学生五体球联赛中 7.场比赛的心率数据与跑动相关数据进行监测,用以量化评估五体球比赛运动负荷特征,并采用数据级数推断法对比了不同阶段比赛负荷的差异性。结果显示:(1)运动员比赛平均心率为(164.5±13.4)次/分钟,约占最大心率的82.5%±6.9%,在比赛时间内运动员每分钟跑动(67.6±14.0) m,其中低强度跑动(速度＜1 2.km/h)距离约占93.1%,高强度跑动(速度≥1 5.km/h)距离仅占2.1%,最大跑动速度为(18.4±3.8) km/h ;(2)五体球联赛省赛阶段的平均心率占最大心率百分比、跑动总距离、加速度负荷、中低强度加速和减速次数、中高强度变向次数、身体冲撞次数和爆发性活动次数皆清晰高于市赛,而最大跑动速度和冲刺跑距离占比则清晰低于市赛(ES为0.95~1.12,可能性75%~95%)。研究结果说明大学生五体球比赛的总体比赛负荷要低于足球和篮球,加速、急停和变向等灵敏性素质是区分五体球比赛水平的显著性指标 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

YO-YO间歇测试与足球运动员比赛跑动能力关联研究 总被引：1，自引：0，他引：1
目的:检验YO-YO测试与足球比赛跑动分析系统的信度与效度,探索YO-YO测试结果与比赛跑动能力的关系。方法:对24名国家男子足球队运动员进行YO-YO测试,对他们在16场国际比赛中的跑动能力进行研究,获取了每名运动员的YO-YO测试结果与比赛中的各种跑动参数。结果:YO-YO测试具有较高的重测信度(r=0.98)和较低的变异系数(8.7%),运动员的测试成绩由于位置不同表现出一定的差异性。SIMI跑动分析系统具有较好的稳定性,观察者内部与观察者之间的变异系数均小于3%,运动员比赛中的跑动能力也由于位置不同表现出一定的差异,且下半场跑动能力下降。YO-YO测试成绩与比赛跑动总距离、有氧高强度跑、无氧高强度跑、冲刺跑频数表现出较高的相关性(r=0.79,P<0.01;r=0.85,P<0.05;r=0.70,P<0.05;r=0.78,P<0.01),而与冲刺跑距离不存在显著相关(r=0.30,P>0.05)。结论:YO-YO测试与比赛跑动分析系统均具有较好的测试信度与效度;YO-YO测试能够反映与比赛密切相关的运动员体能,二者存在高度相关,可作为监测运动员体能变化的一项重要指标。 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

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

The onset of exercise facilitates an improvement in psychomotor performance until the second ventilatory threshold, after which performance is reduced. This inverted-U relationship appears valid for incremental and steady-state exercise, however, not for intermittent exercise. This study examined changes in psychomotor performance of team sport officials during a laboratory-based match simulation. Twelve elite Australian football (n = 5) and rugby league (n = 7) officials (32.5 ± 5.5 years; 180.0 ± 6.8 cm; 78.8 ± 7.6 kg) completed the match simulation on a non-motorised treadmill. Physiological measures were routinely taken, while psychomotor performance was assessed using the Eriksen flanker task (multiple-choice response time). Significant reductions (P < 0.05) were observed in distance covered and high-speed running during the second half when compared to the first. No significant differences (P > 0.05) in psychomotor performance at different time points were observed. Response time was significantly improved when running above 65% of maximal sprinting speed (P < 0.01). This data questions the application of the inverted-U hypothesis for intermittent exercise and suggests that the short high-intensity efforts may not result in the same physiological events that limit psychomotor performance during sustained high-intensity exercise. More so, the high-intensity efforts during the match protocol appeared to promote psychomotor performance during the intermittent exercise. 相似文献

The aim of this study was to compare match analysis (using video recordings) and the physiological load (heart rate measured every 5 s, blood lactate measured after the warm-up, first half and second half) of six 11-year-old soccer players during official games of eleven-a-side on a regular-sized pitch (100 x 65 m) and of seven-a-side on a smaller pitch (60 x 40 m). In both games, heart rate exceeded 170 beats x min(-1) 84% of the time, while blood lactate ranged from 1.4 to 8.1 mmol l(-1). No significant differences were recorded for the physiological parameters. For both matches, walking comprised 38% of total time, running 55%, inactivity 3% and jumping 3%. Although there were no significant differences between halves or matches, running for less than 10 s was 10% more frequent in the seven-a-side game. In the seven-a-side game, there were significantly more passes and significantly fewer tackles, suggesting that seven-a-side matches played on smaller pitches may be more suitable for pre-pubescent soccer players. 相似文献
