Do human movement scientists obey the basic tenets of scientific inquiry?

The nature of scientific inquiry into human movement has received scant consideration. However, an Editorial in Medicine and Science in Sports and Exercise (Raven & Squires, 1989) posed the question,"What is Science?" and asked whether the scientific research reports offered for inclusion in the journal actually obeyed Karl Popper's (1972a) basic tenets of scientific inquiry. This essay analyzes selected examples of research activity in notational analysis (including match analysis), sport psychology, and exercise physiology and argues that there is a prima facie case for suggesting that not all human movement scientists follow Popper's criteria of scientific method.
