Track; implications of speed

                                                           Blog number 4

 When you leave the blocks you accelerate and try to get to your maximum speed. "The success of the reaction phase is determined by the speed of reaction to the gun and the subsequent force exerted against the blocks. After leaving the blocks, the athlete enters the acceleration phase of the sprint(187, Jeffreys). Once you complete the acceleration phase, you should try to maintain your current speed you have and not try to keep accelerating.

"Athletes who have a longer acceleration phase to top speed have an advantage in this phase because they have been required to hold maximum speed for a shorter distance... In considering the 200 and 400 meter sprints, the acceleration stage is lengthened. Unlike the 100 meters, where in most case the athletes aim to accelerate maximally to achieve top speed as soon as possible (188, Jeffreys).  For shorter distances you try to make your acceleration  phase faster so you can get up to your maximum speed before the finish line. But for longer distances like the 200  meter your accelertaio phase typically ends once you turn the curve, so you have a little more time to reach maximum speed









How long do you think the acceleration phase is?

  1. Great tips Bonet! these are especially helpful for athletes who are looking to become a better sprinter. I believe the acceleration phase begins in the first 30-50 meters in a 100m sprint. This is because sprinters have a top speed they reach at end point of their acceleration which they must reach quickly. For me, i do not perform well during sprints because my body is more suitable for long distance. What events would/do you run?

  2. You are absolutely correct. The acceleration phase starts when you leave the block and ends at about 50-60 meters. I run the 100m, 200m, 4x100m and 4x200 meter dashes.
