Twenty Years of Authorship, Sampling, and References in Kinesiology Research Reports

Abstract

This study documented the changes in authorship, sampling, and number of references used in studies published in the Research Quarterly for Exercise and Sport (RQES) from 1996 to 2015. Original research articles were reviewed, excluding reviews, technical notes, and commentary (n = 770). Data were analyzed in 10 biennial groups for the whole journal and by eight sub-disciplinary categories. The median number of authors per paper significantly increased from two to four authors, with a corresponding increase in reports published by six or more authors and a decline in the percentage of reports published by single authors. Sample sizes varied across sub-disciplinary areas, but did not change over time. There was an increase (28%, d = 1.0) in the mean number of references cited by reports. Original research published over the last 20 years in RQES have increasing numbers of coauthors and references, with considerable variation in sampling between the sub-disciplinary areas.
