i am wondering what happened to "CATAPULT" sports.
they are an Australian based tracking company that has most of the globe covered already in sports data management. this last spring they were in bed with the flyers/sabres and i was salivating waiting for the IPO to release.
This data will prove the most useful to the geeks...their system monitors heart rate, breathing, adrenaline spikes, muscle fatigue as well as impacts, speed, shots taken/received and puck tracking. (basically proving Franzen gets excited once a week for 2 mins.)
this will end up being helpful with coach decisions on line changes with real time energy levels on his bench.
this could also improve the +/- system by serving "real" results in being a part of the play, or innocent bystander.
its cutting edge...and adds new pressure to players to be accountable for something else, but i do believe it can be superficially helpful.
if you dedicate your life to being a high paid athlete...you accept the demand, and live accordingly.
