First snowmobile front flip landed and winter sport trauma (video)

Heath Frisby lands the first snowmobile front flip in competition:



This is what happens when the things don't go as planned: Colten Moore flies 120 feet into the air and then hits the snow hard in Snowmobile Freestyle Finals... (video below). He not only survived but went on to win Winter X Games Gold later.



Not all extreme winter sport champions are so lucky though, and some of them have barely escaped death, with life-altering injuries: Kevin Pearce reflects on Sarah Burke's death (USA Today).

Hockey-puck-on-a-rod test checks for concussion after head trauma

From NPR:

The hockey-puck-on-a-rod test was invented by a Michigan high school student.

It works like this: Tester suspends the device while injured athlete sits with forearm on table, fingers loosely circling the stick. Without warning, tester drops stick. Athlete grabs stick as fast as possible. Place where athlete grabs gives an instant readout of reaction time.

It all happens in milliseconds - too fast to measure with a stopwatch. Athletes with concussions had reaction times that were 15% slower.

Comments:

Nicholas Genes - Neat idea. I like how it's free of stopwatches and all the variability they introduce. But it seems that athletes would need to have a baseline measurement pre-trauma to really compare (maybe they can do it when they're signing waivers at the start of the season...)
