well if you want to get faster you should lift weights, take a look at the sprinters in the olympics they are all very muscular even in their upper body and arms

you can do intervals, sprint for 30 seconds, jog or walk for 30 seconds then sprint again, keep repeating this, until you sprint for longer then you jog or walk

also you can buy a parachute that you attach to your body when you sprint so you will run against the air current

also you can push a heavy cart, like a golf cart full of weights, so you can drive into it with your legs,

some people attach a rope around them while somebody heavy holds on to it from behind you while you run and pull them with you

you need to build power, so look up plyometric exercises to build up your power moves

sprinters are strong and explosive

you also need to increase your stride length and you foot speed

you need faster steps and longer strides, to gain speed

finally you can buy a weighted vest and run with it on your body, this will also build strength, when you take it off you will be much faster then you are with it on, and you can always add more weights to the vest as you get stronger, get one that you can adjust the weight of the vest very easily

do this with the intervals this will help you

good luck
