: 說吃禁藥能增加打者2%的XXX(因為有點久了,忘記那XXX是什麼能力...)
: 然後經過計算,那2%就能造就單季選手多轟個10幾20發的HR

Roger Tobin的估計

There is considerable variation among the models, but the salient point is
that a 4% increase in ball speed, which can reasonably be expected from steroid
use, can increase home run production by anywhere from 50 to 100%.


吃藥對幹泡能力的提升可能比大多球迷想像的還要多

不過也別忘了，不是只有打者吃藥，投手也會吃
(被Bonds幹破紀錄轟的那位就是吃藥還被抓)

By the same mechanical analysis, a 10% increase in muscle mass should increase
the speed of a thrown ball by about 5%, or 4–5 mph for a pitcher with a
90 mph fastball. Although there is far more to pitching than speed, (just as
there is far more to hitting than bat speed) there is a significant correlation
between average fastball speed and earned run average (ERA), with an increase
of 4–5 mph translating to a reduction in ERA of about 0.5 runs/game.
