Am i slow because I am underweight?

Question

I ran the 100 m dash at 17 seconds and I'm 14. I am 5'7'' and weigh at around 147 pounds with a waist at around 31-33 inches. Am i slow because I am underweight? Though at football practice I was beating the running backs and linemen by like 5-10 yards on the "gassers". though I didn't get to run against the receivers. Well I ate alot the previous day so I had a lot of enrergy. What should I do to become more fit/fast/strong? (I also play as an offensive and defensive lineman.)

My best mile time was either 5:32 but sure I had a mile time at 5:49.

Answer 1

ur not underweight at all.. in fact ur a little overweight with a 33 inch waist.. im 5'10 210 and i got a 34 inch wasit..... so u should lose some fat and gain some muscle

Answer 2

dont think so. i think maybe your stamana or wat evr (cant spell good 13 years old lol) isnt that good when was the last time u ran?

Answer 3

YOU ARE NOT A SPRINTER. YOU ARE NOT UNDERWEIGHT. With a Mile of 5:32 or 5:49 THAT is really good.

STick with your position you have now.
