In general, conditioning is consider to be activities specific to performance of the sport. That could be sprints, agility, etc. Aspects of the athletic skills invovled. In some ways power drills are also conditioning drills. The separation of the two is not as clear as it is with power resistance training and resistance training in general. Power training can be a form of conditioning training, say having two football linemen oppose each other in an all out attempt for one to get past the other and the other not to allow it. Strength/resistance training is separated by the use of equipment to apply a load in a set movement pattern. Squats for instance would not be consider truly conditioning as control is important to the safety of the movement. Doing a squat with a light load and then performing a sport specific movement on the end/beginning would be more of a conditioning exercise.
I hope that clears it up a little for you. I had a hard work out last night and am a little fuzzy headed today (recovery days are majorly important as I tend to play too hard for my own good sometimes).
