點解我游自由式50米,通常只係得25米係有氣同力,之彼果25就冇,同埋左手1冇咩力推水

通常一般用開右手的人都會有左手冇力既情況,
試下由基本開始再練習,
可以試下拿著浮板練習,可以慢慢改善.
至於冇力既問題可能係你太過用力,
可以試下放輕點來游.

that mean you need to practise your 耐力 for swimming!
I am a swimmer and when i am small, i can't have 氣力 in the whole 50 m, but now,as i practise a lot more than before, i can do it.. and i can swim 400m too!

ADd oil!!!:)

好正常..
明顯你係冇肌耐力..所以25m之後就冇哂力~
建議就返多d肌肉訓練~

仲有小小意見..
50m最好就踢腳有咁快得咁快~
咁你手就會負擔小d~
