I have no idea how a 50G car crash compares to a 50G rugby tackle in terms of risk of injury.
To give an idea, if an 85kg rugby player was running along at a fast 15 km/h and was subjected to 50g of decelerative force, it would take 0.0085 seconds for them to come to a complete stop, faster than their body could register*, and it would be like lying under a mass ≈4200kg.
*I fact checked, apparently our eye-brain connection can process information in intervals as fast as 0.013ms, so possibly faster than the player could perceive.

Sure, but in that example can I assume that 25G would be coming to a stop in 0.017 seconds?
I think most of us here would struggle to notice the difference between those 2 time periods even though 1 is twice the other.
And are human reaction times and perception times the same? I don't have any facts to prove it, but I struggle to believe that.

Still, I'd say it's a pretty meaningful figure.
I'm not quite sure on the point of that article being brought up. I have no idea how a 50G car crash compares to a 50G rugby tackle in terms of risk of injury. On a tangential note though, it'd be interesting to see how the acceleration differs between their head (where the measurements were taken in the above article) and the body. I imagine the head gets the more extreme measurements (obviously I can see the reasoning for focussing acceleration on the head when it comes to sports like rugby & American football).
