Every author approaches every subject differently, but, depending on what kind of life your character lives, you'll likely be doing some research about their job. If the hero or the heroine are cops, spies, doctors, or space captains--well unless you share that occupation, you probably have no idea what their days look like. Or how this job impacts their personality. And if you wan to write a nice, three dimensional character--which you better! if not, be gone! :P--you better inside their head while their holding that gun, or scalpel, or phaser. Not sure how you'd react if that green lady with four tits in the corner hit on you? Better figure it out! ;)  The rules are no different when you're writing sports romance. If you have the passion to write about the sport, you have everything you need to put together a good action scene. Add a few details to bring the reader closer to the action and you have a great action scene. Yes, I'm repeating ACTION. No matter how ...
