[問題] 1500M自由泳冠軍,腳幾乎沒踢水卻能贏?
如題
這是甚麼原理?
為何沒踢水的 比 拼命踢水的 游得快?
意味者:
1.踢水沒啥用?
可是在泳池游的實證是:
雙手不動的前提下
踢水有助於前進
沒踢水則留在原地
因此
應該是 踢水 > 沒踢水
所以
冠軍沒踢水是讓其他人兩隻腳? 以免贏太多讓其他人難堪
2.另有其他秘密?
有沒有內行人可以透露一下
為何奪冠的人幾乎沒啥踢水?

你意思是腳的能量轉換成手的能量?
可以這樣轉換嗎?
所以
他的手的滑動次數比其他人多、且有力? (因為廢掉腳的踢力轉換成手的划力)

可是我看 50M 自由泳所有選手不論手腳 激起的水花都比其他項目大 (亦即阻力最大)
如果依照你的理論
豈不是速度應該最慢
那他們為何用最阻力最大的方式來游 50M?
