目的：探讨专科学校学生“四人制”比赛各时段心率变化的特点。方法：将36名专科学校男学生分为实验组和对照组，实验组学生进行“四人制”的大运动量篮球比赛，对照组学生进行“五人制”全场大运动量篮球比赛。比赛每星期举行一次，分别进行五次。结果：两组学生的晨脉、准备活动后及运动后120min的心率无明显差异，而在赛后1min、5min、30min、60min，对照组心率均明显高于实验组；实验组心率在运动后即刻和运动后5min均为中等强度运动心率水平。而对照组在此时心率达到大强度心率水平。结论：“四人制”篮球赛的运动强度属于中等运动强度，更适合专科生锻炼。 相似文献

通过对青年女子柔道运动员赛前不同训练手段血乳酸及心率的测试,评价不同训练手段的运动强度,为教练员科学安排训练提供依据.以广州队青年女子柔道运动员为研究对象,测试教学比赛课运动员每轮比赛后的血乳酸和心率、测试实战训练课和专项力量训练课的心率,并与其它学者的有关测试结果进行比较分析.研究结果显示:(1)青年女子柔道运动员教学比赛后的血乳酸为(8.01±2.11)mmol/L;(2)教学比赛准备活动与第一轮教学比赛的平均心率和最高心率分别是(121±11)次/min、(146±13)次/min和(160±7)次/min、(183±10):次/min.实战的准备活动和实战第一轮的平均心率和最高心率分别是(146±14)次/min、(168±11)次/min和(158±9)次/min、(171±11)次/min;专项力量训练的平均心率和最高心率为(159±10)次/min、(171±10)次/min.结果说明,教学比赛时,在对手安排和比赛气氛的营造上,要使之更接近正式比赛;要适当提高准备活动的负荷强度,达到准备活动的目的;应适当安排高强度、高质量的训练课,以满足正式比赛时对大运动强度的需求;影响心率的因素较多,为对运动强度进行准确判断,最好对血乳酸和心率同时测试. 相似文献

研究目的：长期以来,对我国篮球运动员科学化训练中生化指标监控的重要性认识不够和监控不足是制约和影响我国篮球发展的主要因素之一,本文采用文献资料法、实验法、数理统计法等科学的研究方法将华北科技学院男篮代表对的十五名运动员对为研究对象,主要进行一下研究：（1）分析其在一次比赛前后心率（HR）和肺活量（VC）的变化及其特点;（2）分析比赛前后血乳酸、Hb、血尿素及血清肌酸激酶的变化及其原因;（3）判定比赛中的运动强度和供能特点;（4）分析比赛后指标变化对运动员的影响。血红蛋白研究方法：（1）在比赛当天早晨测心率、肺活量和血压,在比赛后即刻测心率、肺活量和血压;（2）在比赛当天清晨空腹,赛后即刻,分别测其Hb（Hb）,血尿素氮（BUN）、血清肌酸激酶（CK）和血乳酸。结果表明：（1）赛后运动员的心率明显增高,肺活量却有所下降;（2）运动后BUN、血清CK值明显升高,Hb的值下降。结论：（1）心率、肺活量生理指能反映篮球运动员的机能状况,可以客观地监控有氧训练水平、运动量和强度;（2）利用血红蛋白（Hb）、尿素氮（BUN）、肌酸激酶（CK）和血乳酸（LA）4个指标能准确反映篮球运动员的有氧耐力水平、比赛强度、运动量以及机体的恢复能力;（3）通过科学的检测手段,监控运动训练中的运动负荷,强度,及运动员的是否适应,对避免过度训练和有效的提高运动员的竞技水平有非常大的意义。 相似文献

为了解第八届全国少数民族健身操的运动强度,在比赛前一天的热身赛中,抽取11个参赛队的运动员共51人作为研究对象。通过测试运动员安静、运动后即刻、运动后4、5、6分钟的脉搏来评定运动员的身体机能,运动强度和运动后的恢复情况。研究结果显示：成年人安静心率63.7±6.8次/分钟,运动后即刻心率达到164.8±24.97次/分钟,强度达到中高强度,运动后6分钟心率为75.5±20.8次/分钟,基本恢复安静,心率比安静时高,可能与当时运动现场的环境有关。少年对主要是指山东队,其运动员的安静心率为68.2±3.6次/分钟,运动后即刻心率达到120±29.4次/分钟,强度属于中低强度,运动后6分钟心率为70.5±4.7次/分钟,心率基本恢复正常。 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

The referee has responsibility for control of players' behaviour during competitive football and implementing the rules of the game. To do this, the referee and the two assistant referees are obliged to keep up with play. Referees cover 10,000 m on average during a game, mean heart rate is about 160 - 165 beats . min(-1) and oxygen uptake is close to 80% of maximum (VO(2max). Assistant referees cover approximately 7500 m, mean heart rate is about 140 beats . min(-1) and the corresponding oxygen uptake is 65% VO(2max). Both groups display evidence of fatigue towards the end of the game, a phenomenon that has not been thoroughly examined for nutritional interventions. The estimated energy expenditure of referees during a game exceeds 5600 kJ. Both referees and assistant referees execute unorthodox patterns of movement during match-play that increase energy expenditure over normal locomotion. As high standards of fitness and decision making are expected of professional referees, there are nutritional consequences associated with the training regimes they adopt. The effects of nutritional interventions on cognitive performance during the later stages of a game are in need of further investigation. 相似文献

The aim of this study was to examine the physical and perceptual-cognitive demands imposed on UEFA top-class referees and assistant referees during the final round of the Euro 2000 Championship. To investigate the physical workload, the heart rates during matches were monitored by short-range radio telemetry and translated to different workloads expressed as a percentage of maximal heart rate. For measurement of the perceptual-cognitive workload, video-recordings of games were used to obtain the average number of observable decisions taken by a referee. On average, referees and assistant referees performed the matches at 85±5% and 77±7% of their maximal heart rate, respectively. Over the 31 games, the mean number of observable decisions was 137 (range 104–162), 64% of which were based on communication with the assistant referees and/or the fourth official. To optimize the physical preparation of top-class match officials, the results of this study support the application of intensive and intermittent training sessions, which should place priority on high-intensity aerobic stimuli. In addition, video training is discussed as an additional method for improving match officials' decision making. 相似文献
