从刘翔的成功解析新时期田径运动训练的"三从一大"原则

通过对刘翔训练与比赛的研究,揭示了新时期田径运动训练“三从一大”原则的深刻内涵,即在认识本项目特性的前提下,训练以“从难、从严”为保障,以“从实战出发”为核心,以“科学的负荷量”为关键。同时,注重运动训练过程中科学技术的运用。

大强度运动对机体免疫功能的影响

大强度运动可降低机体的免疫功能,可能与运动时的应激反应、运动时红细胞免疫力降低、运动性贫血、自由基生成增多、线粒体变性以及运动时的营养消耗有关。     

慢性低氧及跑台训练对大鼠骨骼肌肌球蛋白重链(MHC)亚型基因表达的影响

为研究慢性低氧及跑台训练对大鼠骨骼肌肌球蛋白重链(MHC)亚型基因表达的影响,对揭示肌肉收缩蛋白性能的变化机制具有特定的意义.取健康SD雄性大鼠28只,随机分成4组进行试验,采用半定量反转录聚合酶链式反应(RT-PCR)法,测定骨骼肌MHC Ⅰ、Ⅱa、Ⅱx、Ⅱb四种亚型的mRNA基因表达.结果表明:与常氧对照组(C)相比,HC及NT组MHC各亚型mRNA表达量总体呈上升趋势(P＜0.05),仅仅低氧训练组(HT)MHC-Ⅱa亚型mRNA表达量明显下降(P＜0.05);另一方面,MHC各亚型mRNA所占百分比分析显示,慢性低氧能导致MHC亚型mRNA表达出现"由慢到快"变化趋势.另外,慢Ⅰ型百分比并未受慢性低氧及训练的影响.

Training and development of Canadian wheelchair basketball players

Considering the growth in research, examining the development of mainstream sport athletes over the past two decades, studies examining development of athletes with disabilities have been surprisingly limited. While similarities in developmental trajectories between the two cohorts may exist regarding factors such as the value of practice, which tend to be universal regardless of context, disability-related issues (e.g. whether the disability was congenital or acquired) may influence the course of development, affecting variables such as starting age, training and developmental milestones. Fifty-two male and female athletes training with the Wheelchair Basketball Canada National Academy provided detailed training histories. Athletes illustrated similar developmental patterns (e.g. milestones, training adjustments) as they progressed through their sporting career. However, athletes with congenital disabilities started participation in wheelchair basketball and unorganised practice at significantly younger ages (t₄₉?=??4.35, p?<?.001, d =?1.32; t₄₉?=??3.49, p?<?.001, d =?1.03, respectively). While athletes with congenital disabilities continued to reach a majority of the sporting milestones at younger ages, athletes with acquired disabilities were able to reach late career milestones (e.g. national debuts) at similar ages. Athletes’ disability severity did not influence their progress through the developmental milestones and time devoted to training throughout their sporting career. Future work may consider examining developmental trajectories and training histories of athletes in various parasports to extend our understanding of their development and skill acquisition.
