Purpose: To assess the effect of preoperative and surgical factors on return to play (RTP) rates and career longevity of professional rugby athletes after primary anterior cruciate ligament (ACL) reconstruction (ACL-R).
Methods: A retrospective review of a consecutive cohort of professional rugby players undergoing primary ACL-R by the senior author between 2005 and 2019 was undertaken. Athletes were included if they were under contract with a professional rugby team at the time of injury and had a minimum of 2-year follow-up. Univariate and multivariate analyses were performed to determine significant predictors of RTP rate, time and career longevity.
Results: One hundred and eighteen rugby players with 125 ACL-Rs were identified. Return to professional rugby was achieved in 115/125 (92%) of cases at an average of 9.6 months and those athletes participated at the professional level for 5.9 ± 3.4 years after ACL-R. Younger age (p = 0.006) and ACL-R with a concomitant lateral extra-articular tenodesis (LET) (p = 0.013) were predictors of a longer career. A Cox proportional hazards model that controlled for age revealed that athletes who underwent ACL-R with an LET had increased career longevity compared to those with an ACL-R without LET (hazard ratio = 2.74, p = 0.021). No factors were significantly associated with RTP rate or RTP time.
Conclusion: In professional rugby players undergoing primary ACL-R, those having ACL-R with a concomitant LET and younger age predicted increased career longevity. Rugby players who underwent LET at the time of ACL-R had an 18% greater chance of still playing professionally at 5 years compared to those who underwent ACL-R alone.
Level Of Evidence: Level III.

Optimising Instrumented Mouthguard Data Analysis: Video Synchronisation Using a Cross-correlation Approach.

Purpose: Head acceleration events (HAEs) are a growing concern in contact sports, prompting two rugby governing bodies to mandate instrumented mouthguards (iMGs). This has resulted in an influx of data imposing financial and time constraints. This study presents two computational methods that leverage a dataset of video-coded match events: cross-correlation synchronisation aligns iMG data to a video recording, by providing playback timestamps for each HAE, enabling analysts to locate them in video footage; and post-synchronisation event matching identifies the coded match event (e.

Background: Head-on-head impacts are a risk factor for concussion, which is a concern for sports. Computer vision frameworks may provide an automated process to identify head-on-head impacts, although this has not been applied or evaluated in rugby.
Methods: This study developed and evaluated a novel computer vision framework to automatically classify head-on-head and non-head-on-head impacts.

Objectives: To evaluate if the tackler correctly adhering, or not, to four different instructions of legal front-on one-on-one torso tackles altered the tackler and/or ball carrier peak inertial head kinematics.
Design: Controlled laboratory study.
Methods: Fifteen rugby-code players measured with three-dimensional optoelectronic motion capture performed two tackle instructions from the Australian National Rugby League coaching manual on under (Dominant National Rugby League) and over (Smother National Rugby League) the ball tackles, and two novel variants of these (under, Dominant, Torso Stick; over, Smother, Pop, Lock).
Hydrogen gas inhalation prior to high-intensity training reduces attenuation of nitric oxide bioavailability in male rugby players.
PeerJ
December 2024
School of Sports and Health, Nanjing Sport Institute, Nanjing, China.
Background: Inhalation of hydrogen gas (H) as an antioxidant supplement may alleviate exercise-induced oxidative damage and protect post-exercise hydrogen peroxide signaling, which may help mediate beneficial exercise adaptation. The aims of this study were to determine the effects of H inhalation on plasma nitric oxide (NO) level and its synthesis precursor in professional athletes.
Methods: A randomized, placebo-controlled, double-blind, crossover trial was conducted with professional male rugby players for 3 weeks.
