In the elaboration of the mathematical model of the human individual, there is always the temptation to make a model as thorough as possible, which reflects a maximum number of characteristics of the object studied and ensures correspondence with the body down to the smallest details (so-called "powerful" model). , the practice of modeling shows that the most valuable results are due not to the "strong" models, but to the "weak" models, that is to say the models with a high degree of particularization, which model only the specific and most suitable qualities of the organism, which describe only the most important parts of the object, process, phenomenon studied. For the future use of computers, an adequate intellectual training is already needed, based on the mathematical interpretation of the demands of the coaches, the formalization of the pedagogical experiences, the application of new mathematical models in sport.
