Re: 請問投手的表現 有年齡的split嗎

[waitla (おなら体操～!オォーッ！)]

※ 引述《chrislux ()》之銘言：
: 個人的印象是，投手的黃金時期大概在三十歲左右    (28~35?)
: 有任何數據可以對年齡做比較嗎？
: 現在大聯盟老怪物似乎一個比一個強，感受不到年齡的影響
: 請教大家了

   依照 Bill James 對棒球員生涯顛峰年紀所做的研究，一般的生涯顛峰
   會發生在27歲。

   引用BBTN所附的解說...

   Age-twenty-seven peak：
     In Studying baseball players' peak age, Bill James found that for
     players with significantly long career, the most common peak age
     was twenty-seven. More Broadly, the peak age range for players with
     long careers has been pegged at twenty-five to twenty-eight and
     twenty-five to twenty-nine by various reserchers. Improved medical
     care, nutrition, and exercise regimens have helped the current
     generation of players — including future Hall-of-Famers Roger
     Clemens and Randy Johnson — perform at peak levels well into their
     thirties and early forties, leading to speculation that peak age
     may be older than it once was. To date, though, no study has conclusively
     refuted James's findings, suggesting that the Rocket and the Big Unit
     remain outliers.
