Background and problem: on the table tennis training, few people pay much attention on the differentials of individual capacity. We may attribute the failure in competition because of the lack of enough training. Thus, our athletes may receive more training by increasing large amounts of training time and intensity and eventually may cause sport injuries. Even later, their sporting careers are damaged. The purpose of this article is to provide sport coaches a new concept of the scientific training method and selection. The method is to adjust the diagnostic mode by applying the German athletic training. With some basic testing results and specific detection of biological parameters and data analysis, we can understand the individual optimal threshold condition and his capacity, and we can adjust our program and training intensity by giving appropriate doses and prescriptions.
