Unlocking the Impact: A Systematic Review and Meta-Analysis of Biomechanical Insights into Rugby Head Impacts Using...

Area of Science:

• Sports Medicine
• Biomechanics
• Wearable Technology

Background:

• Understanding head impacts in rugby is crucial for injury prevention and player safety.
• Contact sports like rugby pose significant risks for head injuries.
• Biomechanics of head impacts require detailed analysis for effective safety strategies.

Purpose of the Study:

• To systematically review and meta-analyze data on head impacts in rugby using wearable sensors.
• To focus on peak linear acceleration, peak rotational acceleration, and impact location.
• To consolidate existing knowledge for improved player safety and injury management.

Main Methods:

• Systematic search of multiple electronic databases conducted in March 2024.
• Inclusion of prospective cohort studies assessing head impacts with wearable technology in rugby athletes.
• Random-effects meta-analysis model used to combine comparable data from 13 studies.

Main Results:

• Analysis of 13 studies involving 895 participants and 44,036 head impacts.
• Significant heterogeneity observed in peak linear and rotational acceleration.
• Side impacts (44%) were most prevalent, followed by frontal (29%) and back impacts (19%).
• Concussive events showed a pooled peak linear acceleration of 63.01 g; rugby league exhibited higher acceleration than rugby union.

Conclusions:

• Wearable sensors provide valuable data on head impact magnitude and location in rugby.
• Findings emphasize the importance of sensor technology for player safety and injury management.
• Methodological inconsistencies and study heterogeneity necessitate cautious interpretation and further research to standardize protocols.
