训练负荷量参数的变化问题是中跑项目运动训练多年化过程中所要解决的主要问题之一。按Hirsch的观点,在制定中跑项目多年训练计划和不断提高运动员工作能力时,应考虑运动员身体素质的发展和技术提高的问题,并为此而正确制定出训练负荷的量与强度方面的要求。许多作者就不同年龄与训练水平的中跑动运员的训练情况提出了相应的看法。但至今还未研究过不同等级中跑运动员训练和比赛负荷量的因子结构问题。同时还未解决好在训练 The change of training load parameters is one of the main problems to be solved in the process of multi-year training of mid-distance running. Hirsch’s point of view, in the development of multi-year training program for mid-range programs and continuously improve the working ability of athletes, we should consider the development of athletes’ physical fitness and technical problems, and to that end, correctly set the amount of training load and strength requirements . Many authors put forward corresponding views on the training of mid-size runners of different ages and training levels. However, to date, no study has been conducted on the factor structure of training and race load for different levels of mid-range runners. At the same time has not been solved in training
