通过对32名运动员采用体外反搏治疗,观察对比做体外反搏前后的外周阻力、血管顺应性、血液粘度三项指标的变化情况。反搏后外周阻力减少24.6％、血管顺应性增加15.7％、血液粘度下降11.90％。这三项指标的变化,提示体外反搏能加速血液在血管流动,促进氧气与二氧化碳、营养物质及代谢产物的交换,使新陈代谢旺盛,增强人体内脏器官的生理功能。 相似文献

体外反搏(ECP)是一种无创伤性的机械辅助循环装置。近十多年来,在临床用于治疗心、脑、肾、耳、眼以及四肢缺血性疾病均有明显的疗效。LCP技术用于消除运动性疲劳、加速体能恢复,已逐渐被运动医学同仁所重视。本次对9名运动员在大负荷训练期与调整期应用ECP技术进行体外反搏前后观察,结果提示,运动员反搏后提高心功能,改善微循环状态,改善与提高心脏对机体各重要脏器的供血能力,具有良好的血流动力学效应,从而达到了消除运动员由于大负练荷训练引起的全身,尤其是下肢肌肉僵硬、酸痛、无力等不良反应,并达到增强运动员体力,双下肢轻松有劝,促进训练任务完成与提高成绩的效果。ECP技术可做为当前高水平竞技体育训练中一种较理想的消除疲劳、增强体力的措施之一。 相似文献

在竞技体育中，随着竞争激烈程度的提高，消除运动训练所引起的疲劳，迅速恢复体能之重要性已日益显露出来。鉴于游泳、田径均属于体能类运动项目，运动员心血管系统及肌肉系统的疲劳易于产生。我们对本省这两个项目的１２名准备参加“七运会”的运动员进行了有关方面的医务监督，以求尽早对运动员的疲劳程度作出诊断并加以消除。医务监督方法选择心电图，心血管功能以及肌肉硬度测试。对心血管系统及肌肉系统的机能进行评定。以体外反搏消除运动性疲劳。结果表明，体外反搏后运动员的心血管功能有明显改善。运动训练后升高的肌肉硬度明显下降。运动员周身感觉轻松，疲劳感减少或消失。且凡经体外反搏肌肉适时得到放松者，完成技术动作时肌肉感觉良好。无一人肌肉损伤。该阶段运动成绩大多数较为理想。为此，我们认为以心电图，心血管功能及肌肉硬度测试作为对体能类项目运动员的主要医务监督方法，并通过体外反搏来消除运动员运动性疲劳是切实可行的。 相似文献

目的:通过观察世居高原中长跑运动员在高原—亚高原交替训练后各项指标及机能的变化情况,探讨不同海拔的交替训练对耐力性运动项目运动员有氧运动能力的影响.方法:甘孜州体校世居高原的中长跑运动队队员共28名,将运动员随机分为两个组:实验组和对照组,每组14人.实验组采用高原—亚高原交替训练方法,在海拔高度变化的条件下进行训练.对照组采用传统的高住高练模式进行训练.训练结束后进行12min跑测试,并记录在规定12min内跑出的距离,然后对运动后即刻的心率、最大摄氧量、血氧饱和度、血乳酸以及血液指标(红细胞RBC、血红蛋白HB)进行检测.结果:(1)高原—亚高原交替训练后,运动员RBC数目增加,HGB显著增加,高原训练4周后相比,RBC增加更加明显,但HGB数量低于亚高原训练后;(2)交替到亚高原训练2周后12min跑成绩提高了12.2%,连续高原训练4周后成绩降低了2.6%,P<0.05;(3)高原—亚高原交替训练后心率变化不明显,但高原训练4周后心率有所增加,运动后即刻血乳酸水平显著降低,且低于连续高原训练4周后血乳酸值,P<0.05.最大摄氧量和氧饱和度显著提高,P<0.01,与高原训练4周后相比,高原—亚高原训练后最大摄氧量和氧饱和度升高更加明显.结论:(1)高原—亚高原交替训练后,运动员专项有氧运动能力得到提高,而连续高原训练后运动员专项运动成绩反而降低,可能是长时间低氧环境下运动突破了机体对低氧的耐受极限所致.(2)高原—亚高原交替训练能够给予机体一定的缺氧刺激,又能避免高原训练中的不利因素,能够保证有一定的训练强度,从而提高中长跑运动员的专项有氧运动能力.建议:高原—亚高原交替训练能够有效提高中长跑运动员的有氧运动能力,平原地区的运动员到高原进行训练时很难在缺氧环境下保持一定的运动强度,可以让运动员先在高原居住一段时间,等到机体出现高原习服时,对低氧有一定的耐受后再进行小负荷训练,然后再到亚高原进行大负荷训练,从而提高高原训练的成功率. 相似文献

Abstract It is argued that previous studies of active flexibility have not achieved experimental control. An experiment then is described which achieved experimental control by using daily flexibility training over a 7-day period. Forty-two female subjects were randomly assigned to one of six treatment groups or a control group. The six treatment groups received proprioceptive neuromuscular facilitation training for six consecutive days with isometric contraction periods of 0 sec, 3 sec, or 6 sec. Three of the treatment groups followed an active regime (concentric contraction of the agonists) and three a passive regime. All subjects were pretested for active flexibility on Day 1. They were also posttested after training on Day 6, and without training on Day 7. A two factor multivariate analysis of covariance with trend analysis on the period of isometric contraction factor indicated a significant positive linear trend for this factor, approximate F(2, 28) = 7.90, p < .002, together with a significant interaction between this linear trend and the active-passive regime factor, approximate F(2, 28) = 3.81, p < .034. Follow-up tests revealed that this interaction was due to larger gains in active flexibility being associated with longer periods of isometric contraction in the active groups, but not in the passive groups. 相似文献

长期游泳运动对大鼠血浆、胸主动脉内皮素-1的影响 总被引：4，自引：0，他引：4
目的：探讨不同游泳运动对大鼠血浆及血管ET-1的影响。方法：2月龄雄性SD大鼠随机分为对照组(CV)、运动1h组(6次／周)(E1Y)、运动2h组(6次／周)(E2Y)、运动1h组(3次／周)(E3Y)，共进行了14周的无负重游泳。测定了血浆和胸主动脉ET-1的含量；血清SOD、MDA和T-AOC；定期测定大鼠体重。结果：(1)运动各组大鼠体重均低于对照组。(2)运动后血浆ET-1浓度均有升高的趋势，但只有E2Y的差异具有非常显著性；运动后胸主动脉ET-1的变化没有显著性。(3)血浆和血管ET-1与血清SOD/MDA、T-AOC之间并没有相关关系。结论：运动减轻体重，可以降低心血管疾病的危险因素；运动后，血浆ET-1适度升高，可能有助于加强心肌收缩力；未发现ET-1的分泌与机体氧化应激水平之间存在明显的因果关系。 相似文献

The aim of this study was to evaluate the effectiveness of an intervention programme in the physical education setting designed to change attitudes and emotions triggered by potentially risky motor tasks. The individual zones of optimal functioning (IZOF) model was used as a theoretical framework for the study. Italian male and female high school students (N = 84) took part in a 12 lesson intervention and in test?–?retest sessions. The assessment was conducted using the Motor Activity Anxiety Test to measure the students' approach-avoidance attitudes in the face of physical education tasks purported to engender strong emotional reactions. An idiosyncratic emotional profile was also implemented using a list of pleasant/unpleasant emotional adjectives. Two experimental groups were involved in the learning and performing of several potentially risky, highly emotion-arousing tasks, while two control groups were engaged in low-risk team sports. According to the hypothesis of the study, the programme was effective in decreasing the students' avoidance tendencies towards thrilling tasks and in increasing optimal?–?pleasant emotions. Our findings also demonstrated the feasibility and utility of applying the IZOF model to the context of physical education. 相似文献

Abstract This study was undertaken to evaluate the effectiveness of a supplementary physical education program in improving selected motor skills and behavior adjustment of primary school children who were poor in motor skills and deficient in behavior adjustment. Tests were administered to members of two experimental groups (instruction and non-instruction) and two control groups (deviant and normal) at various times during a one-year period. Improvement in motor performance demonstrated by each of the two experimental groups was significantly greater than such improvement made by each of the control groups. The level of motor performance attained by each of the experimental groups did not significantly differ from the level of motor performance exhibited by normal primary school children. Changes in behavior adjustment among the participants were not statistically significant. 相似文献

The purpose of this study was to analyse the effect of regular exercise on spleen and peritoneal exudate reactive oxygen species (ROS) and lymphocyte proliferation by splenocytes. Twenty-four female BALB/c mice were randomly divided into trained (n = 12) and untrained (n = 12) groups. These two groups were further divided into mice that were studied at rest (trained/rest, n = 5; untrained/rest, n = 6) and immediately after a 2 h acute bout of exercise (trained/exercise, n = 6; untrained/exercise, n = 6). The animals were bred in the animal facility of the Yonsei University College of Medicine, where they were housed in a temperature- (22 - 24 degrees Celsius) and humidity- (50 - 60%) controlled environment, with a 12 h photoperiod, and provided with food and water ad libitum. The trained mice underwent 10 weeks of endurance swimming training (5 days per week) in water at 26 - 29 degrees Celsius for 60 min. Changes in body mass, proliferative activity and the production of reactive oxygen species from spleen lymphocytes and peritoneal exudate cells were determined. The splenic lymphocytes of the trained mice had much greater proliferative activity than those of the untrained mice (P < 0.05). Trained mice had lower ROS production in splenic lymphocytes and peritoneal exudate cells than untrained mice. In both groups, there was substantial inhibition of proliferative activity stimulated with medium, concanavalin A and lipopolysaccharide following the acute bout of exercise. This may have been caused by excessive ROS production following the acute exercise session. 相似文献

4周低氧运动对骨骼肌mTOR/p70~(S6K)通路的时程影响 总被引：1，自引：0，他引：1
目的:研究4周低氧运动中mTOR/p70S6K通路的时程变化特征,以探讨低氧训练中的蛋白合成代谢情况.方法:以12周龄雄性SD大鼠为研究对象,分为常氧安静对照组(NS组)、常氧耐力运动组(NE组)、低氧安静对照组(HS组)和低氧耐力运动组(HE组).采用动物跑台训练,低氧刺激为常压低氧(氧浓度13.6%,相当于3 500 m海拔).检测大鼠趾长伸肌的总蛋白含量及mTOR、p70S6K和p70S6K(Thr389)磷酸化表达.结果:在第3天时,低氧因素对mTOR(P<0.05)和p70S6K (P<0.05)有显著抑制效应.在第7天时,运动显著促进mTOR(P<0.01),而低氧显著抑制mTOR( P<0.01)和p70S6K (P<0.01).在第14天时,低氧显著抑制mTOR(P<0. 01)和p70S6K( Thr389)磷酸化(P<0.01),而运动显著促进p70S6K (P<0.01).在第28天时,低氧显著抑制mTOR(P<0.05)和p70S6K( Thr389)磷酸化(P<0.01),而运动显著地促进了mTOR(P<0.01)和p70S6K(P<0.05).结论:耐力运动促进mTOR/p70S6K通路的表达,进而促进肌肉蛋白合成;单纯低氧暴露可通过抑制mTOR/p70S6K表达,而抑制肌肉蛋白合成;低氧耐力运动可削弱低氧对mTOR/p70S6K表达的抑制作用.低氧运动对mTOR及p70S6K的影响有时程变化,且有时程差异. 相似文献

Abstract The degree of contribution to performance of the vertical jump by leg components plantar flexors, knee extensors, and hip extensors was determined experimentally and tested by analysis of covariance. One control and four experimental groups from 100 college men at Brigham Young University were randomly assigned to varying muscle strengthening programs for 8 weeks. Initial and final vertical jump tests and strength measures were administered. Gains in the vertical jump significant beyond the .05 level were registered by experimental groups which strengthened knee and/or hip extensors. Control and plantar flexor strengthening groups did not register significant jump gains. Each experimental group registered significant isotonic strength gains in the programed muscle groups. 相似文献
