Hypertrophy

What distance do you run?

Speed endurance the key to *all* 11/12second sprinters?

I’ve heard that the two types of hypertrophy are myofibrillar hypertrophy and sarcoplasmic hypertrophy. I think myofibrillar hypertrophy provides greater strength and less size, while sarcoplasmic hypertrophy causes an increase in mitochondria and strength endurance (I think). I have three questions about hypertrophy.

Is there a point after which myofibrillar hypertrophy cannot occur without sarcoplasmic hypertrophy since there aren’t enough mitochondria present to support more strength?

If I sprint and am not a powerlifter looking to build massive amounts of strength, is the answer to the above question even relevant to me?

Is the point of sarcoplasmic hypertrophy to build speed endurance? Is this why John Smith always said that at the end of the race you have to depend on your strength from the weight room?
