After read lot of articles about what sprinters doesn´t need to enhance your performance ( or what they need to get in trouble ),
i came here to ask some pearls ( myth ) that we read in somewhere.
Those i can remember;
the list goes on, but who really cares about ?!
Why should a sprinter avoid low speed? I’d say tempo is low speed …
I’m thinking he meant distance running at very low speeds over a long period of time
Avoid having 3 or more girlfriends at one time. 
He is right,
i mean long running or continuous running at very low speed ( like jogging over 20 minutes ).
Jogging, perhaps. But there are quite a few top sprinters who do long runs for 20-30min … not all like them, but they still do them.
Past week,
i saw one long distance runner doing some drills as warm-up,
well, i was over 100m distance, but he looked very fast to me.
BTW, where did you get this information ?
I know a few top sprinters 
and a few former top sprinters.
from the initail list i would not rule out any of them.all canbe used in moderation and with proper coaching such canbe used very successfully
That´s the point here,
maybe i should change the topic title to:
Get IN & OUT,
because, all the “prohibited” is usefull in some part of the sprint career.
But i guess the volume of these works get low as you increase in your career, even more, when you get the speed.
Well, when I think about my level of “speed” doing tempo over 300-400 meter at 70-75% means I’m actually running the same speed like top 10k or even marathon runners. So, yes they look fast to me, too 
(10k in 30 min is approx. 25 rounds at 72secs)
