Applying force to sports
Link | by snypershot on 2010-12-20 12:30:20
Yesterday I was playing Football (not soccer :( ) and was tackled hard, I don't recall the hit that cause me to bleed (probably because I got hit a lot yesterday), but I was hit hard enough that I was bleeding out of my mouth, my question is about how much force do you think was behind that tackle that cause me to bleed?

if you need information like what angle I was hit at and the speed, sorry I won't be able to provide that information.

The best way to measure this would be to have the same person perform the same tackle maneuver on a dummy rigged with a device called an impact force gauge.
This device can be placed where your nose would have been for the simulated tackle, and it will read out a maximum instantaneous force.

It takes surprisingly little force to rupture blood vessels in sensitive areas such as the nose.
I wasn't able to find any data on the minimum force required for this, but you could perform an experiment to measure it.
Simply smack yourself on the nose with the impact force gauge with gradually increasing force.
Once you feel a trickle of blood, check the readout to see the result.
Of course, previous impacts may have weakened the nose, so, for best results, each impact should be on the nose of a new, uninjured test subject.

Have a good science!

thanks for the advice, reminds me of Deadliest Warrior where they try all of those impacts and what not.

you gave me something to wonder about though, how sensitive are the blood vessels in the mouth?

Yeah, I too am wondering about the sensitivity of the teeth inside the mouth. For, I believe they hurt.
