What is 40-meter sprint?

Answer 1

i know americans do a 40 yard dash, which is about 36.576m. They use it to judge an american football players speed (because they are too fat to run 100m)

Answer 2

It's usually used to practice for 3point starts, Block starts and to measure timing over the first leg of the sprint events.

Football players commonly use it for speed timing.

So I would say 40m Sprint is for speed timing.

40 meters is equal to:

43.74453 yards

131.2336 feet

1574.803 inches
