在现代体育运动的训练、比赛和恢复期,运动员的饮食营养问题越来越受到教练员的重视。但不同项目运动员对饮食中各种营养素的需求又有明显差异。本文从运动员对糖、脂肪、蛋白质、水、无机盐以及维生素的不同需求和补充,来讨论耐力性项群陆上项目运动员训练和比赛中的合理营养问题,以促进教练员、医务人员合理调配运动员的膳食结构,保证运动员的营养需求,辅助运动员发挥更大运动能力。 相似文献

青少年三级跳远运动员是我国三级跳远项目发展的基石,但是在＂三从一大＂训练思想的指导下,青少年三级跳远运动员训练时的负荷往往超过了青少年自身所能承受的最大生理负荷,对三级跳远项目的特点和青少年身体机能进行分析,根据实际训练经验,对青少年三级跳远时容易受伤的部位、受伤类型、受伤时机进行研究,并为青少年三级跳远训练提出合理的伤病预防对策和康复手段,从而保障运动员训练的正常进行。 相似文献

目的：通过对比分析多个年龄阶段青少年运动员骨龄与生活年龄的差异以及不同年龄阶段青少年运动员骨龄与生活年龄的差值,探讨青少年运动员的生长发育情况。方法：采用CHN法测定16个项目共2170名青少年运动员的骨龄情况。将男运动员分为6-17岁共12个年龄阶段,女运动员分为6-16岁共11个年龄阶段,比较相应指标间的差异。结果：各年龄阶段男、女受试运动员的骨龄均高于生活年龄;男运动员15岁阶段骨龄相比生活年龄的增加幅度最大,而女运动员最大的增加幅度出现在11岁与12岁年龄阶段。结论：江西省青少年运动员实际生长发育水平高于以生活年龄为标准所体现的发育水平,提示教练员应根据运动员的骨龄来安排训练与营养方案;江西省女青少年运动员骨龄与生活年龄最大差值出现的时间可能早于男青少年运动员。 相似文献

青少年时期是人体生长发育的重要时期,是体育训练的重要阶段,对于运动员来讲,这一时期的营养非常重要.丰富充足的营养会为青少年运动员的正常生长发育提供保障,为创造良好成绩打下坚实基础.全面的营养搭配,对青少年时期的运动训练将起到积极的促进作用,反之,将会使青少年运动员的生理机能和运动能力大幅度下降,极易出现疲劳,影响训练效果.随着现代科学的发展,体育工作者对营养膳食逐渐重视起来,科学的营养补充对于运动员不仅起到维持健康的一般作用,对于提高运动成绩上同样也是一种重要手段和途径. 相似文献

运动员提高身体素质的基础是力量素质,具备良好的力量素质是任何竞技运动项目的运动员获得优异的运动成绩的前提。力量素质是青少年篮球运动员身体素质的基础,注重提高篮球专项力量素质,能够延长篮球运动员的运动寿命和提高篮球运动员的运动水平。因此,要从青少年时期抓起。进行科学、系统、全面的力量素质训练和专项训练,才能培养出更多优秀的篮球后备运动员。所以,篮球教练员对青少年篮球运动员的专项力量训练应高度重视,科学地进行力量训练。本文通过文献资料法,对青少年篮球运动员的专项力量素质训练方法进行了研究。 相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F. 相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language. 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献
