TWENTY- FIVE YEAR TRENDS OF AUTHORSHIP AND SAMPLING IN ISBS PROCEEDINGS

This study documented the trends in authorship and sampling in ISBS Proceedings over the last 25 years. Original research articles of the 1984, 1989, 1994, 1999, 2004, and 2009 proceedings were reviewed for data on authors, sample sizes, sample-author ratio, and rates of single authorship and hyperauthorship (6 or more). Narrative reviews, modeling papers, and technical notes, were excluded from analysis. The mean number of authors per paper significantly increased (71%), along with increased rates of hyperauthorship, and a decline in rates of single authorship (92%) since 1984. Sample sizes varied widely across papers and did not appear to change over time. Increased collaboration in sports biomechanics has not increased sample sizes of original research published in ISBS Proceedings
