目的:探讨皮划艇项目高原训练强度监控的方法.方法:以9名国家皮划艇队划艇组运动员为研究对象,在到达高原第5天,利用递增强度划船测试分析不同浓度乳酸对应的船速和心率,并与上高原前3天的结果进行对比分析,同时测试高原训练期间的血红蛋白、血尿素和肌酸激酶.结果:两次递增强度划船测试表明,在相同乳酸浓度的情况下,高原训练的船速低于平原,但随着训练强度的增加,高原和平原之间的这种船速差异逐渐减小;而在相同乳酸浓度的情况下,乳酸浓度低于6mmol/L时,高原训练的心率低于平原,在乳酸浓度等于6mmol/L时,二者心率相同,乳酸浓度高于6mmol/L时,高原心率高于平原;高原训练可以提高血红蛋白水平,血尿素和肌酸激酶在高原训练期间随着训练负荷的变化而出现变化,但未出现明显的异常值.结论:利用递增强度划船测试可以确定高原训练的合理强度,不宜利用平原的船速或心率来控制高原训练强度,以此方法来确定高原训练强度,可以维持运动员良好的机能状态,并能够发挥高原低氧的促红细胞生成作用. 相似文献

我国甲A足球运动员平原及高原训练时血清睾酮、红细胞有形成分和心血管机能反应特点 总被引：8，自引：4，他引：4

与平原相比我国足球运动员高原训练血清睾酮无明显变化,血液有形成份中RBC、HB和RBC平均体积及RBC体积分布宽度显著性增加。中等强度运动时高原心率反应大于平原,而大强度运动时则低于平原心率反应,同时12min跑成绩也劣于平原。说明RBC、HB的增加是单纯高原轻度缺氧所致,限制高原大强度运动能力的因素仍然是心血管机能。 相似文献

通过对任秀娟高原训练模式的分析与研究得出：高原训练有一个降低训练负荷的环境；与平原训练相比，高原训练中的训练强度略有下降，在野外的训练要多于在田径场的训练；为了确定与某一地区的地理环境相适应，经常性高原训练的地点以相对固定为好。 相似文献

运用文献资料、调查等研究方法对我国优秀女子中长跑运动员陈萍高原训练计划进行了研究。通过对陈萍高原前、中、后训练的运动强度、运动量和训练方法的研究,探讨了陈萍高原前、中、后训练方法、计划安排的特点。研究表明：陈萍高原训练的特点是上高原前强度小,训练量大,主要采用持续跑的训练方法;上高原后训练量略有减少,经过两周的适应期后训练强度增加,并以混合氧训练为主,主要采用间歇跑、重复跑等训练方法;下高原后的前一周以一般耐力训练为主,采用持续跑的训练手段,赛前的专项训练以无氧为主,运动量减少,在训练手段方面,主要采用间歇跑、重复跑为主,兼有氧耐力为辅的训练。 相似文献

通过对甘肃自行车队参加6、7、8、9四届全运会的总结,认为赛前高原训练能有效提高运动成绩.高原训练的关键是掌握好海拔高度,训练时间、强度、营养补充、下山至参赛时间.高原训练的运动量和强度应接近或略低于平原,随着运动员对高原环境的适应,训练量强度和密度应逐步上升. 相似文献

高原训练是我国长跑、马拉松项目冲出亚洲、走向世界的有效途径。如何更加充分地利用高原自然环境，进一步发挥高原训练效果，提高高原训练的成功率，还需要不断探索。一个完整的高原训练过程包括平原大运动量训练阶段、高原大强度训练阶段和赛前平原大强度训练阶段3个部分，应妥善处理三者之间的负荷关系。 相似文献

Strength training with isometric contractions produces large but highly angle-specific adaptations. To contrast the contractile mode of isometric versus dynamic training, but diminish the strong angle specificity effect, we compared the strength gains produced by isometric training at four joint angles with conventional dynamic training. Thirty-three recreationally active healthy males aged 18 - 30 years completed 9 weeks of strength training of the quadriceps muscle group three times per week. An intra-individual design was adopted: one leg performed purely isometric training at each of four joint angles (isometrically trained leg); the other leg performed conventional dynamic training, lifting and lowering (dynamically trained leg). Both legs trained at similar relative loads for the same duration. The quadriceps strength of each leg was measured isometrically (at four angles) and isokinetically (at three velocities) pre and post training. After 9 weeks of training, the increase in isokinetic strength was similar in both legs (pooled data from three velocities: dynamically trained leg, 10.7%; isometrically trained leg, 10.5%). Isometric strength increases were significantly greater for the isometrically trained leg (pooled data from four angles: dynamically trained leg, 13.1%; isometrically trained leg, 18.0%). This may have been due to the greater absolute torque involved with isometric training or a residual angle specificity effect despite the isometric training being divided over four angles. 相似文献

Literature concerning the theoretical role of spinal reflex circuits and their sensorimotor signals in proprioceptive neuromuscular facilitation (PNF) muscle stretching techniques was examined. Reviewed data do not support the assertion commonly made in PNF literature that contraction of a stretched muscle prior to further stretch, or contraction of opposing muscles during muscle stretch, produces relaxation of the stretched muscle. Further, following contraction of a stretched muscle, inhibition of the stretch reflex response lasts only 1 s. Studies examined suggested that decreases in the response amplitude of the Hoffmann and muscle stretch reflexes following a contraction of a stretched muscle are not due to the activation of Golgi tendon organs, as commonly purported, but instead may be due to presynaptic inhibition of the muscle spindle sensory signal. The current view on the complex manner by which the spinal cord processes proprioceptive signals was discussed. The ability of acute PNF stretching procedures to often produce a joint range of motion greater than that observed with static stretching must be explained by mechanisms other than the spinal processing of proprioceptive information. Studies reviewed indicate that changes in the ability to tolerate stretch and/or the vis‐coelastic properties of the stretched muscle, induced by PNF procedures, are possible mechanisms. 相似文献

Introductory textbooks commonly state that Golgi tendon organs (GTOs) are responsible for a reflex response that inhibits a muscle producing dangerously high tension (autogenic inhibition). Review of the relevant data from animal studies demonstrates that there is wide variability in the magnitude of, and even the presence of, GTO autogenic effects among locomotor hindlimb muscles, and that data on GTO effects under conditions of voluntary maximal muscle activation are lacking. A single available study on GTO function in humans, during a moderate contraction, surprisingly shows a reduction in autogenic inhibition during muscle‐force production. Further, it is not possible to find experimental evidence supporting the idea that strength training may produce a decrease in GTO mediated autogenic inhibition, allowing greater muscle activation levels and hence greater force production. 相似文献
