to me training is when you do another activity to help with the one you want to pursue. Like if I was a runner I might train by swimming, plyometrics, gym and stuff. I know that it can be classed as training to actually go running, but you don't really need to learn as much with running, you just need to get fitter and stuff.
Personally I would see it closer to "practising", I would rather call it that as that's pretty much what you do, you go out and practice gaps or sidehops and stuff, it sounds weird in my head saying "I'm going out to train my gaps".
If I was to train for a comp I would go running, go to the gym, stuff like that, then I would go out and practice the actual techniques.........sounds way better in my head like that.
