By re-contemplating the formation and functions of training theories, the author drew the following conclusions: some training theories are right while the others are wrong, and not all training theories can be used for guiding practice; the precondition for a training theory to guide practice is that the theory must be right, and only scientific training theories can guide training practice; in training practice, the accuracy, contempo-rary nature and scientific nature of a training theory are the intrinsic factors that restrict the training theory to exert its functions, while the cultural and theoretical capacities, retrospecting awareness and capability, sports intelligence, theory applying and practice exercising capability as well as creative thinking of coaches and athletes are the sub-jective factors that restrict the training theory to exert its functions; in the mean time, the separation between train-ing theories and training practice will also hinder the exertion of the function of theories guiding practice, and the best way to realize the unification of training theories and training practice is behavior study.
