壘球新規則對打擊成績之影響－以2000年雪梨奧運、2004年雅典奧運為例

本研究的目的是在探討2001年國際壘球總會修訂之規則對於壘球競賽打擊成績之影響。引用競技運動最高層級之奧運會壘球競賽為例，比較2004年雅典奧運參賽隊伍在新規則規範下，與2000年雪梨奧運會使用舊規則時，其攻擊能力與臨場表現之差異性。結果發現，打者在安打數比率增加17.96%、打擊率增加19.02%、打點增加16.13%、犧牲打亦增加了26.53%，可是在全壘打、盜壘數及四壞球保送等方面之表現卻顯著減少。證實規則之修訂，增加全壘打牆的距離造成打擊者擊出全壘打之困難度大幅提昇；投手板距離的增加，減少三振出局比例，投手在比賽的主導能力亦相對降低。

The purpose of this study was to investigate the effect of the renewed regulations by International Softball Federation on hits performance. The subjects were the softball matches in Sydney and Athens Olympic Games, the most competitive level. The important conclusions were (1) the increased rates were 17.96% in hits, 19.02% in hits average, 16.13% in RBI, and 26.53% in SH. (2) the frequencies in homerun, steal and four-ball, however, were decreased. It proved that the renewed regulations- the lengthened distance of homerun wall, made homerun more difficult than before with the lessened 48.15%. The extended distance from the pitcher to the home base decreased 27.92% in stroke-out rate; the pitcher's predominating will be diminished comparatively.
