The Value and Design Thought of Serial Research in Sports Science

Scientific research has continuity and needs accumulation bit by bit. Serial studies can consolidate the facts observed in scientific research and promote the progress of science. The value of serial studies mainly includes: Validating the replicability of research, improving the validity of the research, providing strong evidence and chain of evidence for science research. Serial studies in sports science can design from the perspective of improving the internal validity of research, through controlling of additional variables, exploring mechanism, adding moderate variables, and transforming research methods. From the perspective of enhancing the external validity of research, serial studies can be carried out by changing the manipulation methods of independent variables, transforming the measurement method of dependent variables, transforming the research situation, expanding the group of subjects and expanding the application field. Of course, the above research strategies can also be combined to advance the serial studies in an orderly manner. This article expects more and more researchers to use series of studies designs to provide strong evidence and evidence chain for the discovery and practice of sports science research.
