运动训练中,选择适宜的运动强度提高训练效果和运动成绩,是当前训练负荷发展的总趋势。为分析乳酸与短跑能力的关系和乳酸与短跑运动代谢特点及乳酸在选材中的应用,运用文献资料法分析短跑运动中的乳酸变化,结果发现短跑运动后的血乳酸浓度与运动强度、运动量、训练水平、糖原含量以及缺氧等因素有着密切的关系。高水平运动员的最大血乳酸值高。利用血乳酸指标能够反应不同运动方式及不同运动强度下能量供应情况和机体耐受情况,反映运动训练的水平,可广泛应用于短跑运动训练的监控和选材中。可考虑将45-60米段落跑的成绩和血乳酸值共同评价运动员的速度水平,成绩好且血乳酸值低的运动员应作为重点对象加以考察;将80米的成绩与其血乳酸值结合起来,共同评价运动员的速度耐力水平。 相似文献

血乳酸是糖元成血糖的无氧代谢的最终产物。因此是评定人体在运动过程中无氧代谢情况、运动强度、疲劳状况的重要生理指标。目前国内外在冰球训练和比赛中越来越重视测定运动过程中血乳酸值。为了了解我国运动员甲级冰球队在训练中采用不同的训练强度,不同的负荷时间和不同的间歇时间时,血乳酸和心率的变化规律,我们于1989年冬对我国34名甲级冰球队的运动员在训练中的血乳酸情况进行了研究。 相似文献

血乳酸测定在摔跤训练中的初步应用 总被引：2，自引：0，他引：2
目前,国内外已广泛运用血乳酸这一生理指标评定运动员机能状况,训练强度及预测运动成绩,但运用血乳酸来评定摔跤训练的强度报道甚少。为帮助运动员合理安排运动量及选择恰当的训练手段有效地发展运动员有氧代谢及无氧代谢能力,我们于2000年12月至2001年11月测定了西藏自治区男子摔跤队运动员九运会比赛及训练课中乳酸值的变化。 相似文献

A comparison of physiological responses to rowing on friction-loaded and air-braked ergometers 总被引：2，自引：0，他引：2
The physiological responses of 10 trained rowers to a progressive incremental rowing protocol to exhaustion were investigated on Gjessing, Rowperfect fixed-mechanism and Rowperfect free-mechanism rowing ergometers. Heart rate, oxygen uptake (VO2), ventilation (VE) and blood lactate were determined at matched power values for each ergometer. The mean power and heart rate at the lactate anaerobic threshold were determined by graphical interpolation of data for each ergometer. Analysis of variance and linear regression showed differing responses at matched power and an approximate 40-50 W difference in power at the lactate anaerobic threshold when comparing the friction-loaded Gjessing with the air-braked Rowperfect fixed and Rowperfect free ergometers (P<0.01). No significant differences were noted when comparing the air-braked Rowperfect fixed and Rowperfect free ergometers. However, comparisons of VO2, VE and blood lactate at given heart rates and of heart rate at the lactate anaerobic threshold showed no significant differences between ergometers. Our results indicate similar physiological profiles for all ergometers tested when compared at equivalent heart rates, but differences when compared at matched power. A direct comparison of the data from Gjessing (friction-loaded) with Rowperfect fixed and Rowperfect free (air-braked) ergometers would therefore require a correction factor for inter-ergometer variation in displayed power data. 相似文献

运动对心肌组织能量代谢的影响 总被引：6，自引：0，他引：6
综合分析了安静状态时、运动状态下心肌组织能量代谢的特点及长期运动训练对心肌能量代谢的影响作用。安静状态下 ,心肌组织以有氧代谢供能为主 ,尤其是以血液游离脂肪酸的有氧氧化供能为主。运动时 ,随运动强度的增加 ,心肌组织内源性、外源性能源物质的消耗均增加 ,心肌不但吸收乳酸 ,而且自身也产生乳酸。长期运动训练可以使心肌组织的糖酵解代谢能力、有氧代谢能力均得到提高。 相似文献

Software for calculating blood lactate endurance markers 总被引：2，自引：2，他引：0
Newell J Higgins D Madden N Cruickshank J Einbeck J McMillan K McDonald R 《Journal of sports sciences》2007,25(12):1403-1409
Blood lactate markers are used as summary measures of the underlying model of an athlete's blood lactate response to increasing work rate. Exercise physiologists use these endurance markers, typically corresponding to a work rate in the region of high curvature in the lactate curve, to predict and compare endurance ability. A short theoretical background of the commonly used markers is given and algorithms provided for their calculation. To date, no free software exists that allows the sports scientist to calculate these markers. In this paper, software is introduced for precisely this purpose that will calculate a variety of lactate markers for an individual athlete, an athlete at different instants (e.g. across a season), and simultaneously for a squad. 相似文献

Plasma testosterone and cortisol responses to prolonged sculling in male competitive rowers. 总被引：5，自引：0，他引：5
In this study, we examined anabolic and catabolic hormone responses to a single endurance rowing training session in 12 male competitive single scull rowers. A work intensity eliciting a blood lactate concentration of 4 mmol(-1) was determined on a rowing ergometer during an endurance rowing training session lasting about 2 h (7891+/-761 s; distance covered 22.6+/-2.5 km; heart rate 136+/-7 beats x min(-1); intensity 77.4+/-3.8% of anaerobic threshold; mean +/- s). Venous blood samples were obtained before and after on-water rowing. Cortisol, testosterone and sex hormone binding globulin were measured and free testosterone and the free testosterone: cortisol ratio calculated. Blood lactate concentration did not change significantly during training (from 1.7+/-0.4 to 1.9+/-0.4 mmol x l(-1)); however, body mass was reduced (from 82.0+/-10.8 to 80.6+/-11.2 kg) and was related to the distance covered (r = -0.75). The concentrations of cortisol and testosterone did not change significantly during rowing or in the first 2 h of recovery. Free testosterone was reduced in the first 2 h of recovery, but no significant changes were observed in the free testosterone: cortisol ratio. Immediately after rowing, the concentrations of cortisol (r = 0.49) and free testosterone (r = -0.58) were related to the distance covered. Our findings indicate that a prolonged low-intensity training session results in a similar anabolic and catabolic hormone stimulus for trained rowers. 相似文献

耐力运动对自由基、血清超氧化物歧化酶活性影响的研究 总被引：23，自引：0，他引：23
为探讨耐力运动对自由基、超氧化物歧化酶活性的影响,对32名运动员进行了安静、小运动量训练、大运动量训练负荷下血中丙二醛(MDA)、超氧化物歧化酶(T-SOD、Mn-SOD、CnZn-SOD)、血乳酸测定.发现小运动量训练后SOD、MDA值与安静状态下相比无显著性差异,而大运动量训练后SOD、MAD与安静值相比有显著性差异(P＜0.01),提示耐力运动与短时大极量运动一样可导致体内MDA含量升高,SOD活性升高. 相似文献
