Well, there is no one simple, easy answer. There are many different models, and throw in sports specificity. I can say this though, most models are whole body oriented, the body is one piece (as Dan John says) and is used that way in sports, so train it that way, i.e. no real reason to focus on bodyparts for sports oriented training.
Nolw most programs include several cycles of "off season" training, periodized, which consist of several microcycles, to include an adaptation phase )which sounds similar to what you're doing now), a strength buildup, and a powr buildup phase. The offseason goes for strength, strength endurance, cardiovascular training, and power. When the season approaches, a preseason routine is usually undergone, getting more into sports specificity and addressing what you will need for that sport. Sets/reps, intensities vary with microcycles, sports, etc. Dr. Tudor O. Bompa has a good book out called "Periodization Training for Sports", and I recommend you read it. Also, go to http://www.athletes.com
They have separate sections for most sports, a forum, and lots of articles and routines set up for most sports. Bodybuilding is not necessarily sports training.
