抱歉喔,我說不管不代表沒有資料
剛好前幾天就有一篇英文報導在談投球計時跟受傷的相關
https://theathletic.com/4465791/2023/05/02/mlb-pitch-clock-velocity-injury/?amp=1
MLB’s pitch clock is a success, but some still fear an injury reckoning is coming
標題稍微有些殺人,所以我們還是細看內文比較好
裏面訪問了一些球團相關人士,有擔憂的有覺得不影響的,所以目前質性意見上還有分歧,那我們就純粹來看數據的情況
首先他提到第一點,投手投球速度現在還是在上升的,且每局投球局數也更多,但相對的速球用量卻減少
那這些改動的確有人反應會導致投手受傷,但這跟投球計時的相關性又如何呢?
The rate of injuries at the minor-league level actually declined in 2022 following the adoption of the pitch timer. The total rate of pitcher injuries per day of the regular season, as documented by club medical staff, decreased from 2021 to 2022.
先行實施的小聯盟已有兩年的數據可以參考
2020 119人
2021 110人
小樣本,但還是減少了
基本上我們無法肯定投球計時與受傷有正相關,甚至用最簡單的回歸模型看還是低程度的負相關
但即使如此,還是有些人認為這樣的計時會導致受傷風險增高
“If you have a pitch clock, and it’s limiting the time they have to rest and replenish the energy source, we run into problems where they may not be prepared enough to actually compete or stay non-fatigued during the rest of the outing.”
Sonne wrote that the minor-league pitch clock should lead to more injuries based on a study he referenced on these pages, and also referenced work that found shortened periods of time between pitches increased the signs of fatigue in baseball players up to two days after throwing
疲勞跟體力的消耗更明顯,但後面也有提到這是雙向的,投手投球的時間也相當減少
然後也提到投手調配體力變難的問題,讓他們很難在想催球速的時候催球速
最後提到,即使球速下降和疲勞傷痛,跟球速和球季長度的關係還是比較直接,且運動員也正在適應此種情況
結論,投球計時器跟受傷有沒有關係,根據數據可能沒有,根據質性評論,有人擔心但都只是體感,而且基本上跟追求球速和球季長度關係比較多
所以現在喊受傷跟投球計時有關的其實就是空話比較多
