Re: [討論] 跑鞋在長距離過程中衰退?

[ULTIMA1002 (晚點再說)]

RUNREPEAT 12/3 正好發了這篇文章介紹了各種中底材質跟特性,
下面某段有做實驗,結果是建議跑鞋中底在長距離使用後需要休息48hr以恢復中底的壓縮

節錄:
You may have heard from a friend that it's essential to let your shoes
recover. Well, it's just like that.

In this chart created by the American-based company Dow to showcase the
advantages of its EVA + OBC compound, various foams undergo static
compression at room temperature for 22 hours. Afterward, they’re set for
recovery during 24 hours. If a foam manages to return to its original shape
entirely, it will have a compression set of 0%—which doesn’t happen at all.

The results are truly astounding. Surprisingly, regular EVA foam outperforms
EVA + OBC in the 30-minute test, although it falls short in both variants
over 24 hours. However, when compared to a TPU foam—like Boost or PWRRUN—
the difference is absolutely astonishing.

To err on the side of caution, establish a rotation of 2 or 3 pairs of shoes
and wait at least 48 hours before using the same model again. And as happens
with you, the longer and faster you run, the more rest your shoes will need
to recover. By doing so, you'll not only enjoy better leg protection and
bounciness, but you'll also extend the lifespan of the shoe by allowing it to
fully recover between workouts.

推 isohera: 離題了，題目是跑多少會衰竭
→ isohera: 你回答，跑完要換鞋讓鞋休息
推 tudnste: 哪有離題，就是跑完會壓縮才要你換鞋，只是正確的數值沒
→ tudnste: 人測。但可以確定的是跑完中厎確定會被壓縮不會恢復
推 Acoustics: 我印象推文這篇有更相關
推 Acoustics: https://reurl.cc/blL5NE
→ Acoustics: 好幾個月前我推的文 仔細內容忘記了== 我每天看一篇論
→ Acoustics: 文保持語感(我都用法文說話比較多)
→ Acoustics: 大大這篇也有相關啊
推 Acoustics: 推
→ Acoustics: 很新呢
推 Acoustics: 文章裡面的metaspeed突然覺得好好看
推 bowenwin: 這篇很好啊，跑多久衰退什麼的根本不重要，比賽鞋跟長距
→ bowenwin: 離訓練鞋，一場比賽提供足夠的避震是絕對夠的
→ bowenwin: 會覺得不夠是自己肌力的問題或選錯鞋
推 ksjr: 可是換個方式想 選一雙衰退慢一點的鞋可以讓弱弱的腳腳稱更
→ ksjr: 久阿 推文a大那篇用的是eva泡棉 而這篇剛好有比較各種不同泡
→ ksjr: 綿的比較，雖然沒有完整的報告可以看不曉得測試方式是什麼
推 jj840917: 推~
→ ksjr: 說完就找到了有兩篇 https://reurl.cc/Wv5L89
→ ksjr: https://reurl.cc/Ryp19x  一個dow在推銷自家產品的概念
推 jj840917: 所以鞋子在跑步過程中衰退是真有其事 至少這篇文章的結
→ jj840917: 論是支持這個論點的! 算是長了知識
→ jj840917: 也好奇實驗測試的結果有沒有數據XD
推 ksjr: a大貼的那篇有阿 這是圖 https://reurl.cc/1Gd4MV
推 wjack: 長知識！
推 uei1201: 第一個推文的真的很重要，前一篇開頭推文這是肌力弱，商
→ uei1201: 人的陰謀，後面沒人敢說鞋子會越跑越硬，一開口就承認這
→ uei1201: 是自己肌力弱XD
推 locka: 感謝分享~長知識~ 但樓上大大這樣說大可不必吧講的好像我在
→ locka: 帶風向@@ 我不過是個分享個人感覺的鄉民，大家願意討論跟找
→ locka: 資料打我臉我都很歡迎的^^"
→ locka: 是說我沒有否認衰退這件事啊，我用另一種講法(多久感受到疲
→ locka: 勞)詮釋，也說各家鞋的確有差。
→ locka: (對應推文大大提供的圖來解釋好了)我的論點從來都不是否認
→ locka: 衰弱的存在，而比較像是，我們能不能在10-20公里內感受到那
→ locka: 6%(32%->26%)的能量吸收耗損，有的人能、有的人不能，如此
→ locka: 而已。不過還是感謝這篇的分享，看來鞋子跟人一樣都是需要
→ locka: 休息的哈哈哈
推 KobeFuck: 單純推locka大的客觀
推 HardRealTime: locka，我覺得他不是在說你。
→ locka: 我是上一篇第一個推文的，所以才出來解釋一下~不過沒事啦，
→ locka: 大家都是理性討論的^^
推 isohera: 當你懷疑鞋子的當下，你就找到跑不好的出口了
推 isohera: 彈性物質會被壓縮形變，但不至於全馬里程內不堪使用。
推 Acoustics: 給iso跟lock大推
→ Acoustics: 是的 不然能幹嘛== 換鞋
→ scotthsiung: EVA本來就有這些問題,TPU--->PEBAX變得壓縮Y比較好
