I actually have a math based degree and spent quite a bit of time studying statistics.
Now I'd be lying if I said I break down the data of every study that comes out, hardly ever actually. I do whatever everyone else does and read the results. Now, I don't think it's bad advice to tell people to be skeptical at all, but I do check things out from time to time, and when the people compiling data together are people well qualified, things tend to check out. I think the problem comes from being able to tell what is a good study and what is NOT a good study, with considerations of the SOURCE!. And most of us read a summarization of a study in the press and not the actually study itself. Myself included, but when I have dived in things tend to check out when the source is good.
People are trying to get things right. Data scientists aren't dumb, and the doctors, surgeons, athletic trainers all want what's best.
I don't think there's some secret national cabal of evil doctors, athletic trainers, surgeons, sports trainers etc etc etc. that aren't interested in finding out what is leading to the cause of a rise of injuries among mlb players With a relative level of comfort, I trust those studies.
Obviously it's something. they have decades of data now from the onset of all these "sports labs" they put kids in to up performance and to be quiet frank the leading explanation makes complete 100% sense to me. As a former athlete and someone who has been entrenched in the fitness industry their whole life it makes absolute sense to me that throwing harder and pushing your body's limit during a violent un-natural movement is going to increase your risk of injury. That makes sense to me, I'd be very surprised if that was not the case.
It will be interesting to see if the pitch clock does add to that. I'd think if anything it would wear pitchers out quicker, and that might actually end up putting a little less stress on the arm. That's literally a hypothesis made while writing this, I don't know but it is interesting.
