when you accelerate from the line, do you...

when you accelerate out at the start, are you supposed to keep springing along faster and faster and let the speed come to you from the ground?

or are you supposed to push forward on the track aggressively?

because i’m afraid that if i try it the first way i’ll get way too far behind, but when i push through aggressively i can stay in the front, even though it seems to mess up my leg technique for the rest of the race, but i can still finish top 2
