Doing squats, deadlifts, snatches, cleans, jerks, and push presses will give you plenty of upper body work. You can augment that work once or twice a week, but working on movements that may or may not increase power while adding significant mass to the upper body will be significantly detrimental to power and force generation.
Quite honestly you could make the case like muffy that increasing aerobic capacity and power fit into the whole organism argument as well. I tend to agree with that approach. However, there needs to be some constraints, do you want to be a bodybuilder, powerlifter, a distance runner, or a sprinter. If you want to be a sprinter, you have to move away from things that are not related to pure speed, speed endurance, pure power and power endurance related.
What davan is referring to in organism strength, is the crossover between upper and lower body strength. It really has nothing to do with size it's all about neuromuscular coordination. The training that would bring about the most hypertrophy mainly taxes the PNS, but heavy low rep lifts also are very taxing on the CNS. In this way you can bring about strength improvements without overly taxing the specific muscles in training. This idea has several applications, for example before competition stopping heavy lower body lifts, but continue with upper body lifts or really hitting upper body strength hard when injury prevents running and/or lower body lifting.
