Actually they do improve your quick twitch muscle movements which is why sprinters are faster, baseball players hit the ball farther and throw it harder, and so on. They wouldn't have been so prevalent in the Olympics if they only affected pure strength. What use do swimmers have for pure strength? I'm not sure how this myth that steroids don't help baseball players first got started, but it's completely untrue. They won't help you hit a ball, but they will help you hit it farther. Just like they wouldn't help a pitcher locate a pitch, but they will help him throw it harder. I think the most likely scenario would be that if Braun is guilty he was taking something to stay healthy. Now you're just making stuff up. That is absolutely not true at all. Steroids add bulk, and tons of slow twitch muscles, and generate almost all of their additional mass in the upper body, when in baseball, the overwhelming majority of power comes from the lower body. http://steroids-and-baseball.com/medical-effects.shtml#DISTRIBUTION http://link.springer.com/article/10.1007%2FBF00626282 http://steroids-and-baseball.com/DeVany.old/DeVanyHomeRunMS.pdf
