Abstract
BackgroundRugby league is a popular collision sport among Australian adolescent and young adult men. Concussion is one of the more common injuries in rugby league. Few studies have examined concussion in youth rugby league. To examine medically diagnosed concussions from a single season within two elite-level pathway rugby league competitions by evaluating game play risk factors and conducting a video review of potential concussion signs. MethodsAll players involved in the Queensland Rugby League's (QRL) under 18 years and under 20 years age group competitions during the 2019 season were included in this study. Data included all head injury assessments (HIAs) identified in real-time through the QRL injury surveillance system for these two QRL age group competitions. The purpose of this study was to (i) report the rates of HIAs and medically diagnosed concussions; (ii) examine video signs of potential concussion; (iii) review game play risk factors related to HIAs and concussions; and (iv) determine the number of days until a concussed player returned to match play and the number of subsequent games missed by concussed players. ResultsThere were 86 HIAs and 30 medically diagnosed concussions from the two competitions. The concussion incidence was 2.93 per 1000 player match hours in the under 18-year age group and 5.75 per 1000 player match hours in the under 20-year age group. Slow to stand was the most commonly observed video sign (78.6%; 22/28 concussions). Most concussed players (91%, 21/23) missed at least one subsequent game (M = 1.4, SD = 1.7, range = 0–7 games), with the average days to return-to-play being 15.7 (SD = 7.0, range = 7–41 days). ConclusionsIn elite-level pathway rugby league, the incidences of HIAs and medically diagnosed concussions were higher in the under 20 age group than the under 18 age group. Both age groups had lower incidences of HIAs and concussions than professional adult rugby league players. Return-to-play following concussion was similar across the two age groups and differed considerably compared to the elite level, with a longer time before return to play for the younger elite level development pathway players.
