中长跑负荷难度的确定、计算和运用

从中长跑训练中的负荷量、负荷难度和负荷密度给运动员施加的困难程度入手，结合训练实践，对负荷难度的确定、计算和运用进行了说明，从而得出了比较科学的理论依据，对运动负荷搭配形式给出了相应的系数，量化了训练负荷，确定了量难度、强度难度和密度难度的计算方法，明确训练负荷的特点，寻找训练的动态作用点，增加新刺激的含量，提高训练的积累效果和运动水平，为教师提供训练的技术理论和方法。

The Definition ,Calculation and Application of the Degree of Difficulty of the Load in Middle-distance and Long-distance Race

According to the difficulties exerted on the players from the quantity,degree of difficulty and density of load in the middle-distance and long-distance race,the authors obtained the scientific theoretical basis by explaining the definition,calculation and application of the degree of difficulty of the load. The authors also gave the relevent coefficient of the load form for players,measured the training load,decided on the calculation method of the difficulties of the quantity,intensity and density,clarified the characteristic of training load,looked for the movement coherent point for training,added the content of strong incentive,raised the accumulate effect and the standard of sport so as to provide the instructor with technical theory and method.
