Tackle higher or lower? Simulation to evaluate how changing the tackle height would impact the number of concussions and head acceleration events in men's professional rugby league

Listen to this summary

The authors aimed to evaluate how changing tackle height in men's professional rugby league affects the incidence of concussions and head acceleration events (HAEs). Their simulation, based on data from the 2023 Super League season, revealed that lowering tackle height could reduce concussion and HAE risks for ball-carriers, while potentially increasing risks for tacklers. These findings suggest that policy changes regarding tackle height could be informed by the simulated outcomes, highlighting a protection paradox.
