So I've been trying to find sources that discuss the actual science behind this, but of course that's very hard to find. I've been skeptical about the effects steroids has on hitting power in baseball. Maybe it affects people in other sports, but with hitting power in baseball I am skeptical. For one, I heard that steroids affects the upper body more, but hitting power in baseball comes from the lower body. People I've spoken to have retorted that it improves hand/eye coordination so hitters will be able to react faster on a pitch and drive it out. However, there are a lot of hitters in baseball with good hand/eye coordination, but can't hit for power because they don't have the lower body strength to do so. Anyways, I was wondering if anyone could give me some scientific answers on this subject. Do steroids affect hitting power in baseball?
