Now, in all honesty, you might not need to fully understand exactly what flexing and extending does to your board so long as you know when to use them, but I do believe that by understanding what's happening, you'll become much better rider because you will know how the inputs, that's the things you do on top of your board, affect the outputs, the things the board actually does underneath you.
現在,老實說,只要你知道什麼時候使用它們,你可能並不需要完全理解彎曲和延伸對你的衝浪板到底有什麼影響,但我確實相信,通過了解發生了什麼,你會成為更好的騎手,因為你會知道輸入(即你在衝浪板上面做的事情)如何影響輸出(即衝浪板在你下面實際做的事情)。
