After 2000 AD, the diameter of the table tennis increased from 38 mm to 40 mm. There have been a great number of studies related to the training and instruction adjusted according to the increase in sphere. This study aimed to investigate what instruction concepts the previous studies had provided, then what facets these concepts presented, and whether these concepts were practicable for the coaches in the training of the table tennis. In order to understand the above questions deeply, this study first explored the previous studies on the increase of the sphere. In addition, it analyzed the contents of these studies based on the knowledge tree. Finally, the study synthesized these concepts of training and instruction to provide some conclusions and suggestions as follows. First, when physics and kinematics parameter were applied extensively after the increase of the sphere, these concepts described and inferred on the basis of quantitative analysis was mostly Intuition Inferences, which was not correct enough to convey the exactness of the concepts of training and instruction in these studies. Second, the previous studies showed superficial aspects in Metaphysics, narrow aspects in the Methodology, and insufficient scopes in Logic. It deserved a second thought on whether these concepts should be applied to the training practice. Third, the concepts revealed in the previous studies mainly recommended to enforce muscular strength, explosive force training, and persistence ability, and to strengthen an overall capability of playing table tennis. Forth, this study suggested adopting more experimental, verification, and investigation methods to explore the concepts of training and instruction. Verifying whether the theoretical concepts provided by the scholars were practicable by training the players in practice was the best way. Moreover, the table tennis coaches from all levels of schools should constantly keep discussing over this issue in order to set up a universal concepts of training and instruction according to the increase of the sphere. Hence, it is expected that the skills and standard of the table tennis will be promoted.
