Why is a crouch start used in sprinting?

Answer 1

Newtons 3rd law of action/reaction says that their is an equal and opposite reaction for every action. When starting from a standing start you have less force pushing you off so there is a smaler reaction. But when starting from the starting blocks your down low with bent legs so you can push yourself off resulting in a greater reaction.

Answer 2

Hi. I am twelve and love to run. Crouch starts are used in running because they always give the best results (If you do them properly.) If you stuff up your start in a race, the race can be easily lost. There is a slight difference between block starts and crouch stars, even though they are basically modified versions of eachother. A block start is used by a confident runner who know how to start properly and has trained using blocks. A crouch start nowdays is often used by teenagers who know what they're doing but can use blocks just yet.







Hi I am sixteen just done this in P.E, Newtons 3rd law of action/reaction says that their is an equal and opposite reaction for every action.
