The whole multi-year training process of athletes usually includes basic training stage, special improvement stage, best competition stage and high level maintenance stage.

Each stage has different training objectives and tasks, and then there are different requirements for training content and exercise load arrangement. Obviously, the best competitive stage is the most important core stage in the whole training process for sports training activities with the goal of creating excellent sports results.

Embedding the self-connection mode throughout the multi-year training process.

In the whole multi-year training process, there are obvious differences in training characteristics between two adjacent intervals, and in the process of realizing the transformation, it also shows flexible gradual characteristics. Because of the different competition demand, duration and organizational characteristics of multi-year training stages in each interval, the system development relationship between adjacent training stages is also different.

Therefore, the ways and forms of overlapping between stages are different. Therefore, there are four training processes that are separated by many years. Through the close connection of each link interval, it becomes a relatively balanced, patchwork and systematic whole, thus forming a nested link mode with overlapping pairs.
