Top end speed is your highest possible speed. This isn't necessarily about increasing speed, rather your ability to maintain your fastest speed in an efficient way. Top end speed can often be trained through improving mechanics and even neuromuscular efficiency. Acceleration refers to the rate you increase your speed from stopped or a slow speed to your top end. Ultimately, how quickly can you go from zero to 100. And deceleration is the opposite of acceleration. Deceleration refers to your ability to slow down quickly and efficiently.
