basically, sprint more.
Work on power development for your legs and foot speed, as well as sprinting technique.
double-unders (for foot speed and quickness), box jumps, footwork drills, starting drills (off the blocks), overspeed training, parachute training, etc..
there are a lot of things you can do...
why do you want to improve it? for track or for fun?
