OK. Hey, Sam, tell us a little about your study. Yeah, so this study, I wanted to investigate the relationship between angular momentum of the body and both be in baseball pitching. Essentially, we wanted to answer the question of how exactly are the momentum time series looking like as well as what does it actually matter to both be because it's not something that's really been done before, especially when looking at our relationship to the actual performance output. Now really in the past, people looked at angular velocity of different body parts compared to both speed. So you're looking at. Regular momentum instead, yeah, which is a different way. And what did you find. So what we found was, as this is a first analysis, we are we are indeed taking like the peak values. So we looked at the angular momentum for each of the limbs of the body and then torso, and we did a linear mixed model to find any relationships with both speed. And what we did find is that not only are we found a lot of associations between angular momentum by the left for axes, which is something I'll talk about later about we found a little associations between the torso, the pigeon and the whole body. Angular momentum about leftward and both speed and this is again not something that's been previously quite emphasized yet, but now there's some sort of connections that we can build further research questions on into the future. Again, you're talking about getting the police speed, the angular momentum of different body parts of the pelvis, upper trunk, upper trunk, arms all the way onto it up the chain, correct. Thanks.
