Abstract: In this study it was hypothesized that elite butterfly performance is characterized by wave motions with particular frequency, amplitude, and phase characteristics. Particular emphasis was accorded the question of whether 'waves' travel along the body during the butterfly stroke. Selected body landmarks and the center of mass (CM) of eight elite males and eight elite female swimmers were quantified. Fourier analysis was conducted to determine the frequency, amplitude, and phase characteristics of the vertical …
