I need to fish up an old article that I read back during the time of the Mitchell Report, but actually quite a few baseball players were using banned substances.... but, they weren't using them to get ripped or enhance strength, they were using them to assist in recovery from the knocks and bruises of a long MLB season.
This article was written by a relief pitcher... in it, he describes how after every outing where he pitched live game outs, the next day his arm would be really sore, stiff, and tight. The relief pitchers called it the "pitching hangover". Starting pitchers didn't have to worry about it so much because they had three or four days rest before they were scheduled to pitch again, but amongst relief pitchers, it was a common annoyance... after pitching, it took them hours of stretching and warming up the next day in order to get the muscles loose and ready to be ready for a potential game appearance. This pitcher claimed that he was introduced to some substance, I forget which one, that he would take in the evenings after he would pitch. He claimed that the first time he tried it, when he woke up the next morning, he was SHOCKED that his arm felt completely normal! No soreness or stiffness, no "hangover"... which of course made his life a lot easier because he didn't need the hours of stretching and treatment in order to get back into game shape for that day's action.
This pitcher, and of course this is just hearsay, implied that it was only a really select handful of players who were juicing in the manner that Bonds was, in an attempt to get huge and bulk up the muscle. But, there were a much larger number of players who were doing low level stuff to ease the muscle pains, stiffness, and soreness... and improve their recovery after periods of exertion. From what I remember, he painted this in the context of a baseball player's life... unlike other sports, baseball players play almost every day, with usually only one day off every week and a half or so. Add to this the constant travel, time constraints on how much maintaning exercise they could get in, etc... and these substances just made their lives a lot more bearable and less painful.
He also went on to say that PEDs weren't the only "lifestyle enhancing" stuff they were doing... he said there are low level amphetamines that are commonly used by players to overcome jet lag, lack of sleep the previous night, etc. Actually, this particular claim might not have been from the pitcher's piece, it may have been from the Mitchell Report itself... I can't remember right now.
It was really an interesting piece, it painted a very interesting context on the demands of being a baseball player.
And, in my recollection of some of the more candid passages from the Mitchell Report, the first thing that came to MY mind was that such stuff definetly can't be just limited to baseball. I firmly believe that there are PEDs of one sort or another being used in ALL professional sports.
Including golf... and most certainly soccer.
