Abstract: From the perspective of methodological significance, the author tried to explain the significance and value of existence of scientific problems in sports training theories, how to find scientific problems, and how to solve these scien-tific problems. Scientific problems determine targets for training theory study, trigger the constant development of training theories, and bring benefits to training practice; scientific problems in sports training theories are mainly scientific prob-lems about the patterns of such 4 external relations as competitive ability structure, training load structure, training method structure and training process structure, as well as scientific problems about the patterns of such 4 internal relations as competitive ability biological adaptation, training load allocation, competitive ability component coordination and training complexity; for realizing breakthroughs, research methods should be changed from qualitative to mixed, from unitary to crossing, research objects should be changed from macroscopic to microscopic, from description to explanation, research paradigms should be changed from simple to complex, from cause and effect to correlation, and research paths should be changed from construction to deconstruction, from retention to innovation.
Key words: competition and training；sports training theory；scientific problem
