Can i become a faster sprinter? Like what should i do to increase my sprinting speed and decrease the 40 yard?

I wanna be running back for football in 10th grade and i lift weights but im not black so im gonna have to work extra hard XD. To increase my speed should i sprint for like 30 minutes a day and also should working my legs out with extremely heavy weights increase my acceleration and speed. Like squats dead lifts and lunges?Can i become a faster sprinter? Like what should i do to increase my sprinting speed and decrease the 40 yard?
1. Being racist isn't cool dude.

2. To become faster, you have to build your fast twitch muscles. Yes, you have to do 4-6 reps at your max for the 100-200 meters. For the 400 meters, you have to do 6-8 reps at your max. In addition to your weights, do sprint repeats. You could get a simple training program for this just simply typing, for example, "100 meter training" on google. Something should pop up. Some examples of repeats include 4 X 60s, 6 X 50s, 4 X 100s at "flying" pace (max pace). Also, don't put on extra bulk by eating 4000 calories, even if you peaked and want to become stronger. Bulk is murder. Good Luck!
