目的：比较在赛前训练阶段采用加压训练结合SIT训练与单独SIT训练对公路自行车运动员运动能力的影响。方法：将12名云南省女子公路自行车运动员随机分为两组，在训练前后分别进行身体成分测试、递增负荷测试和Wingate无氧功测试。结果：（1）两组运动员训练前后体重、肌肉量无明显变化，加压组体脂率较训练前差异呈显著性（P＜0.05），对照组骨骼肌含量较训练前有显著差异（P＜0.05）；（2）训练后加压组最大摄氧量相对值、无氧阈心率 、最大心率与每搏输出量较训练前差异非常显著（P＜0.01），最大有氧输出功率较训练前差异呈显著性（P＜0.05），对照组各指标的变化趋势与加压组相似，但增长幅度较加压组小，无氧阈心率、最大心率较训练前差异呈显著性（P＜0.05），每搏输出量较训练前差异呈非常显著性（P＜0.01），两组运动员VE均较训练前有所下降；（3）训练后加压组峰值功率、相对峰值功率、平均功率、相对平均功率较训练前差异呈显著性（P＜0.05）；对照组峰值功率与相对峰值功率较训练前差异呈显著性（P＜0.05）；平均功率与相对平均功率较训练前稍有下降。结论：（1）赛前3周加压训练结合SIT训练和单纯SIT训练均可引起机体蛋白质分解代谢和降解加速，而导致骨骼肌含量下降；（2）赛前加压训练结合SIT训练和单纯SIT训练均可有效提高公路自行车运动员的有氧运动能力，且加压训练结合SIT训练较单纯SIT训练的增长幅度更明显，训练效果更佳；（3）赛前加压训练结合SIT训练可有效提升公路自行车运动员爆发力水平和无氧耐力水平。 相似文献

为了了解我国优秀青少年冰球运动员运动能力状况。对24名优秀青少年冰球运动员身体训练期的运动能力进行监控,测定其Yo-Yo间歇恢复测试（YIRT）指标及血乳酸、心率、最大摄氧量等运动能力指标,并探讨运用YIRT监控冰球运动员身体训练的可行性。结果表明：身体训练后青少年冰球运动员YIRT成绩和最大心率具有非常显著性提高（P〈0.01）,YIRT后的血乳酸具有显著性提高（P〈0.05）,最大摄氧量无差异（P〉0.05）。表明青少年运动员的速度和耐力能力有所提高,可以推断青少年冰球运动员身体训练供能是以糖酵解系统为主,有氧氧化系统为辅,磷酸原系统参与部分动作的模式。相关性检验结果显示YIRT与血乳酸具有一定相关性。建议应进行长期、阶段性的连续监控研究。 相似文献

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·l -1 . The amount of high-intensity running during a match was related to the Yo-Yo intermittent recovery test ( r 2 = 0.57; P ? 0.05) and the 12 min run ( r 2 = 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· 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

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.

Abstract The purpose of this study was to determine the ability of individuals with a cervical spinal cord injury to achieve and sustain a cardiorespiratory training intensity during wheelchair rugby. Nine wheelchair rugby players completed a continuous peak exercise test on a SciFit Pro I arm ergometer with stage increases each minute to determine peak heart rate and power output. Approximately one week after peak exercise testing, heart rate was recorded (every 5 s) during three regularly scheduled rugby training sessions. Data were analysed to determine the number of continuous minutes that participants spent above 70% of heart rate reserve under various rugby training activities. The percent of time spent at or above 70% heart rate reserve varied across participants and conditions. Continuous pushing was the least variable training condition among participants with the sample averaging greater than 73% of time above the target heart rate. Scrimmage training was highly variable across participants with a range of 0% to 98% of time above the criterion. Results of this study indicate that wheelchair rugby training enables some participants to reach a training intensity associated with improved cardiorespiratory fitness, and that the type (or kind) of training activity dictates the extent to which individuals sustain such a threshold. 相似文献

The aim of this study was to determine the alterations in oxygen uptake kinetics following endurance training in previously trained athletes. Sixteen competitive cyclists completed 8 weeks of supervised endurance cycle training. Ventilatory threshold, maximal oxygen uptake (VO2max), oxygen uptake kinetics and simulated 40-km time-trial tests were performed three times over a 4-week period before training, and then after 4 and 8 weeks of training. The protocol for measuring oxygen uptake kinetics consisted of three square-wave increments from unloaded cycling to a power output of 78 W followed by a single increment from 78 to 156 W. No significant differences in any variables were observed over the pre-training period. The ventilatory threshold and VO2max increased, and the time for 40 km decreased (P < 0.05) with training. Shorter VO2 time constants and lower heart rates were observed during the protocol for measuring oxygen uptake kinetics (same absolute power output) post-training. These results indicate that oxygen uptake kinetics may be improved with endurance training in previously trained athletes. 相似文献

The effect of training on aerobic power characteristics of young cross-country skiers 总被引：1，自引：0，他引：1
H Rusko 《Journal of sports sciences》1987,5(3):273-286
The influences of growth, training and various training methods were investigated by analysing long-term training effects in young cross-country and biathlon skiers (n = 129). Some athletes (n = 49) were studied six times in three years and some at least once a year during a four year period (n = 48). During three summer training periods skiers emphasized either intensive training or distance training or continued to train normally. The results indicated that maximal oxygen uptake (VO2 max) and heart volume increased between 15 and 20 years of age and the most significant changes in heart volume were observed between 16 and 18 years of age. International level skiers were able to increase their VO2 max and heart volume even after 20 years of age. Anaerobic threshold (AT, ml kg-1 min-1) increased like VO2 max but when expressed as a percentage of VO2 max, the AT was similar in every age group over 16 years of age. Intensive training at the intensity of anaerobic threshold or higher was observed to be most effective in producing improvements in VO2 max. Low-intensity distance training was more effective in producing improvements in anaerobic threshold. 相似文献

采用两种不同的无氧阈测试方法(乳酸法和Conconi法)对赛艇运动员进行测试,并比较其结果的相关性。结果表明:其无氧阈血乳酸值无显著性差异,无氧阈心率存在显著性差异,心率之间的差异有可能是由最大乳酸稳定状态下的个体乳酸阈最大速度引起的,在赛艇训练中以Conconi测试的心率拐点作为无氧阈训练的评定指标更有利于运动员有氧耐力水平的提高。 相似文献
