I almost mentioned Nolan Ryan, but I figured that true baseball fans would get my point when I mentioned “power pitchers over 40”.
There is a book out on the physics of baseball - I don’t have it but I read it in the book store while my wife shopped one day. According to the book, the reason why pitchers lose speed as they age has little to do with muscles. Much of the speed of a fastball is because of the snap of the arm, which comes from flexibility of ligaments. As we age, ligaments get less flexible, hence less snap. I don’t see how roids affects this.....else they’d recruit pitchers at weightlifting competitions. I think it’s quite possible that Clemens juiced, but adding muscle shouldn’t add MPH. His exercise regimen may have more affect on ligament flexibility than the steroids - seems to me that some others who kept their speed into old age (Ryan & Steve Carlton come to mind) were also workout fanatics. Haven’t heard if Randy Johnson works out, other than horizontally......
