AUTHORSHIP AND SAMPLING PRACTICE IN SELECTED BIOMECHANICS AND SPORTS SCIENCE JOURNALS

In some biomedical sciences, changes in patterns of collaboration and authorship have complicated the assignment of credit and responsibility for research. It is unclear if this problem of "promiscuous coauthorship" or "hyperauthorship" (defined as six or more authors) is also apparent in the applied research disciplines within sport and exercise science. This study documented the authorship and sampling of patterns of original research reports in three applied biomechanics (Clinical Biomechanics, Journal of Applied Biomechanics, and Sports Biomechanics) and five similar subdisciplinary journals within sport and exercise science (International Journal of Sports Physiology and Performance, Journal of Sport Rehabilitation, Journal of Teaching Physical Education, Measurement in Physical Education and Exercise Sciences, and Motor Control). Original research reports from the 2009 volumes of these biomechanics and sport and exercise journals were reviewed. Single authorship of papers was rare (2.6%) in these journals, with the mean number of authors ranging from 2.7 to 4.5. Sample sizes and the ratio of sample to authors varied widely, and these variables tended not to be associated with number of authors. Original research reports published in these journals in 2009 tended to be published by small teams of collaborators, so currently there may be few problems with promiscuous coauthorship in these subdisciplines of sport and exercise science.
