Yes, as do all speed-strength sports; however, remember that the barbell must travel fast enough to be caught in the bottom position. A large amount of “speed” is needed, more so than strength is needed. Yes, strength and speed are connected, yet it is the opposite of what most think. A fast man can make himself a strong man, but no strong man will make himself a fast man. I usually do not like to simplify things, but speed training is generally more stress inducing than strength training. Thus why you can lift “heavy” 3-4x a week, yet cannot sprint that many times a week at a maximal level. Recovery is more important when speed is a considered factor. Thus, in my opinion, the reasoning that recovery is needed more than drugs that have a favorable effect on enchancing absolute strength.
