不同训练手段对机体无氧代谢能力的影响 总被引：1，自引：0，他引：1
采用实验法，测试了不同训练手段下的血乳酸值。结果发现．45—60m段落跑后血乳酸急剧升高，形成血乳酸激增的“转折”阶段；30-45m段落是发展磷酸原系统供能能力的最适跑距；60-80m主要发展速度耐力。实验组经过10周不同段落的训练后．其非乳酸能和乳酸能供能能力、100m跑成绩、PAP、AAP发生了不同的反应，并于训练前和对照组相比均有显著提高。同时表明，10s超极量强度无氧训练法并不能明显提高磷酸原系统的供能能力。 相似文献

乳酸阈训练对蹼泳运动员有氧耐力的影响 总被引：1，自引：0，他引：1
应用个体乳酸阈对18名青少年蹼泳运动员的有氧耐力训练进行了8周实验研究，纵向观察有氧训练、无氧训练、有氧无氧混合训练三种方式对运动员有氧耐力生理指标的影响。结果表明，三种不同方式在个体乳酸阈强度训练下对运动员的心肺功能指标均具良好的生理效应，但从有氧耐力所获训练效果显示，有氧无氧混合训练方式最优。 相似文献

不同专项训练对男子短距离自行车运动员无氧能力的影响 总被引：2，自引：2，他引：0
分析两个阶段不同侧重的专项训练前后男子短距离自行车运动员无氧功和专项成绩的变化,探讨不同专项训练对无氧能力的影响,为合理安排训练计划、评价训练效果提供依据。在冬训期间,对运动员的15s、30s无氧功和场地专项成绩测试结果显示,专项力量训练提高了运动员的磷酸原供能能力,但8周训练时间过长,造成了专项频率水平的降低,影响了成绩。专项频率训练虽然使无氧能力小幅下降,但对运动员骑行频率的改善从整体上提高了短距离运动员的专项成绩。在训练计划的制定中,应合理安排各种专项训练手段的比例。 相似文献

心率、血乳酸在赛艇科学化训练中的应用探讨 总被引：4，自引：0，他引：4
对赛艇训练中常用的训练手段进行血乳酸、心率的监测,发现在常用的训练手段中,心率、血乳酸浓度和运动负荷的强度大多有较好的对应关系.在训练实践中,心率可作为控制赛艇训练强度的有意义的参数.4mmol/L无氧阈功率训练不能达到乳酸状浓度的最高稳定态训练,无氧阈功率训练对提高运动员的有氧耐力能力的效果欠佳. 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

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

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

对训练周期理论和板块训练理论进行了比较后发现，两种理论的冲竞占、主要集中在高水平运动员是否适应新的参赛机制和高水平运动员专项能力提高的生物适应性以及训练理论模型适用的训练范围上；而对两种理论的辨析与思考，得出了训练理论与训练实践脱节的原因是训练理论模型的非真理性和训练理论模型的经验化。 相似文献
