Conservation of angular momentum in sport

Conservation of angular momentum in sport.

I was hoping for some examples of sports such as diving where conservation of angular momentum is important and how it applies to the sport etc.

Feel free to go in depth, I am looking some good examples of it's importance.

cheers!

Gymnastics, Diving: The degree of tuck in a flip/spin regulates the spin rate. A tighter tuck = faster rotations than with a looser one.

Figure skating; one of the best examples is spin rate as the arms are drawn in. Synchronized swimming for the same reason. I'm not exactly sure if shotput, dicus and hammer-throw count in this, but you'll note that the participants get a good spin going before letting go. It's not exactly conservation of angular momentum, but at least a translation of it into linear motion. Pool, if you want to consider that without conservation, you couldn't keep spin on the cue ball. Same for baseball, golf and tennis; trick pitches/drives/serves wouldn't work if the ball quit spinning.
That's all that come to mind right now, but as you can see, it's an extensive subject.
