Type 1 “Slow Twitch” Muscle Fibers vs Type 2 “Fast Twitch” Muscle Fibers MCAT Biology & Biochemistry

I have a question that has never been asked and has never been discussed anywhere. It's about fast twitch fibres.
There is very contradictory information about it.
Apparently they are useful for strength and explosive strength against a high resistance, but then you ask about quickness against a low resistance and the answer is - "fast twitch fibres"
Now look at certain ultra quick boxers, they arent the strongest or have the biggest punch, and then look at slower stronger boxers - which ones are more likely to have high numbers of fast twitch fibres? the stronger ones or the quicker ones?
What really causes the quickness in the quickest boxers? if they apparently have more fast twitch fibres then why arent they the strongest as well?
something is off or just ignored around this topic and this question never gets answered

Does it mean type 2 do not use oxygen? Or they use oxygen less in the process?

thank you so much

Why hypertrophy occur only in type two x fibres?
Why its cell size increases

Thank you for helping me understand my MCAT question 🙏🏾

well explained.

Thank you it was so helpful 👍
