美国游泳界越来越关注年龄组运动员离开游泳运动的人数。美国每年大约有180000青少年运动员参加游泳运动 ,大约60000人离开这项运动 ,35%的流失率与其他运动的流失率基本相同。为了更深入地研究这个问题 ,美国游泳界和美国奥林匹克委员会心理研究学会共同研究为什么一些青少年运动员仍然继续参与竞技游泳 ,而另外一些却中断了训练。许多调查研究试图了解动机对运动员继续参与和中途退出的影响。关于青少年运动员参与运动的动机包括 :乐趣、提高技术、结交朋友、改善/保持体型 (Weiss &Chaumeton,1992).回…  相似文献

目的探讨"高住低练"过程中,运动员安静时血清酶的变化规律.方法20名运动员随机分为高住低练组和低住低练组,每组10名,分别测定运动员在此过程中安静状态下血清肌酸激酶(CK)、乳酸脱氢酶(LDH)和谷丙转氨酶(ALT)的活性.结果在高住低练的初期,运动员血清CK、LDH活性明显高于对照组,而高住低练4周后,血清酶活性则明显低于对照组,并可连续到高住低练后2周.结论提示运动员在2 500m高度进行4周高住低练,机体对缺氧负荷和运动负荷的适应后,能降低由于运动引起的血清酶活性的升高,对防止肌肉组织的损伤和增加细胞膜的稳定性有一定的作用.  相似文献

目的:将复合式训练应用于中国冰壶国家队运动员的非冰期与冰期衔接阶段中,探讨其优化精英冰壶运动员扫冰能力的效果。方法:采用常规力量训练与复合式训练分别对备战北京冬奥会的冰壶国家队全体20名运动员实施8周线性周期力量训练,测试训练前、后运动员的力量素质、扫冰推拉压力、扫冰频率以及扫冰绩效值,采用协方差分析测试数据,计算训练效果的组间效应量(d)。结果:相对于常规力量训练,复合式训练更能提高国家队冰壶运动员的扫冰推出压力峰值、拉回压力均值/峰值、扫冰频率、扫冰绩效值(d=0.9~2.8),但改善扫冰推出压力均值的效果较小(d<0.2)。结论:复合式训练比常规力量训练更有利于提高我国精英冰壶运动员的最大扫冰推出压力、扫冰拉回压力以及扫冰频率,从而优化扫冰绩效值。  相似文献

The purpose of this study was to assess the effect of periodized resistance training on accelerative sprint performance. Sixteen physically active men participated in a randomized controlled study. An experimental group (n = 10) completed an 8-week periodized resistance training intervention, while a control group (n = 6) did not train. Pre- and post-training measures of 20-m straight-line sprint time, including a 10-m split, maximum strength, and explosive strength, were recorded. Flight time, stance time, stride length, and stride frequency were quantified from digitized video recordings of the first three strides of the 20-m sprint. Resistance training resulted in significant increases in maximum strength (parallel back squat: 19%) and explosive strength (6-10%). However, both groups increased 0-10 m sprint times (experimental group = 6%; control group = 3%) while 10-20m times were reduced (experimental group = 7%; control group = 4%), highlighting the mechanical differences between the distinct sprint phases. The change during the 0-10m interval was accompanied by a reduction in stride frequency during the first three strides. Strength coaches should be aware that the potential benefits of increased muscular strength during short sprints are likely to be affected by mechanical specificity and that improvements in sprinting performance may not occur immediately after a period of resistance training.  相似文献

探讨青春发育期男性青少年在生长发育过程中骨密度(bone mineral density,BMD)值与下肢跳跃能力的关系及运动训练对其影响。对10~20岁男性青少年63名,依据年龄分为10~15岁和16~20岁组;依据是否从事规律的运动训练,再分为运动员组和非运动员组。超声法测量跟骨BMD,下肢跳跃能力指标使用日产Rebound Jumping测跳仪测量。结果:男性青少年的BMD在整个青春期呈上升趋势,且10~15岁和16~20岁组BMD有显著性差异;运动组和非运动组的BMD也呈显著性差异,提示早期运动训练可以改变骨密度;男性青少年的BMD与反映下肢跳跃能力的指标具有明显相关性,且此相关度受运动训练的影响,运动训练具有正向促进作用。  相似文献

In this study, we examined the acute effects of manipulating exercise order when combining countermovement jumps and loaded parallel squats in a complex training session, and the acute effects of countermovement jumps and loaded parallel squats on sprinting performance. Eight rugby players participated in five trials, including two that involved performing loaded parallel squats followed by countermovement jumps or vice versa in a randomized cross-over design. Peak rate of force development and peak force were measured during countermovement jumps and loaded parallel squats. Peak power, jump height, and duration of amortization phase were also determined during the countermovement jumps. Peak force during squatting was significantly greater in both cross-over treatments (loaded parallel squats-countermovement jumps and countermovement jumps-loaded parallel squats) compared with the control (P 相似文献

This study compared the effects of two velocity loss thresholds during a power-oriented resistance training program on the mechanical capacities of lower-body muscles. Twenty men were counterbalanced in two groups (VL10 and VL20) based on their maximum power capacity. Both groups used the same exercises, relative intensity and repetition volume, only differing in the velocity loss threshold of each set (VL10: 10% vs. VL20: 20%). Pre- and post-training assessments included an incremental loading test and a 15-m linear sprint to assess the force- and load-velocity relationships and athletic performance variables, respectively. No significant between-group differences (P > 0.05) were observed for the force-velocity relationship parameters (ES range = 0.15–0.42), the MPV attained against different external loads (ES range = 0.02–0.18) or the 15-m sprint time (ES = 0.09). A high between-participants variability was reported for the number of repetitions completed in each training set (CV = 30.3% for VL10 and 29.4% for VL20). These results suggest that both velocity loss thresholds induce similar changes on the lower-body function. The high and variable number of repetitions completed may compromise the velocity-based approach for prescribing and monitoring the repetition volume during a power-oriented resistance training program conducted with the countermovement jump exercise.  相似文献

足球运动员耐力素质训练的新思考   总被引:3,自引:0,他引:3
