This post is a continuation of the ongoing in the wild review of the Vector Mouthguard System. You can see the previous posts about what I have experienced to this point by clicking on the hot links. As always if you have questions please comment, email or tweet I will do my best to answer.
The system has been on site and in the hands of the kids and I for the past nine days; the good is far outweighing the bad at this point. However, there is plenty of things that I have yet to figure out or apply, rather figured out how to apply. Tomorrow is the first game action, a point in this trial that I am both scared and excited about for the Vector Mouthguards. Time for the bright lights.
I am not scared or apprehensive about the overall performance of the data that I have been seeing thus far. One thing that I can firmly state at this point is that the perceived accuracy and consistency of impacts below 50g is all that I hoped and more. As the practices have progressed and I have reviewed the hitting drills by film, the hits of the interior lineman and linebackers seem to show on almost every play where there is full effort. This would match up with my line of thinking about football (as a reminder I have my system set up to report impacts of 10g or greater), this is a collision sport. I guess at this point I wonder if I am collecting a lot of “noise” in the system because the amount of hits it is recording. I do want to see the overall number of hits collected by the kids but if the 10-20g range of linear impacts are doing nothing other than that, it makes me think. On the other side I do want to have that data in case a kid were to be injured and it was a very low threshold.
The not so awesome thing at this time is the frequency of the anomalies I have seen. The last number I remember seeing for total hits that the system had captured was nearly 2,000 (4o players for 8 days of practice, about 6/player/day) and that number seems about right to me. But, the real issue is of that nearly 2,000 data set there are 12 hits that have exceeded 80g on the monitor and none of them “looked” like an 80g hit on film, in fact some there was no contact. Granted this can happen with technology, some part of an algorithm that didn’t weed out this report. Upon review I was able to identify four of these instances: one was previously mentioned with a player yelling (I have since reboiled the mouthguard and have not seen from that sensor), one was a player whipping out his mouthguard and kicking it while it still had some spit on it, and the other two were the cause of a coach tapping – rather slapping – the mouthguard on the helmet after taking it out of a players mouth to mess with me. In regards to the last two instances the good thing is that this only happens one time because the mouthgurad deactivates when the slobber is off.
