В аджилити (собачьих соревнованиях) действительно используют лесенку типа стремянки.

Почему только собачьи??

Во многих видах спорта проводятся тренировки на маневренность с использованием лесенки.

Agility Ladder
In various fields of sports competition, the body is constantly asked to perform movements from unfamiliar joint angles. The main objective for agility ladder programs is to promote a wide range of different foot and movement patterns. These skilled movements become second nature and the body is able to respond quickly to various angles that are required in sporting events.
We can improve our agility by practicing the movements in training and an agility ladder is an essential tool in a complete agility program. The standard ladder is 10 yards long with 18 inch squares but you can construct your own ladder using sticks or tape.
When beginning an agility ladder program start with 2 to 4 drills and once you master these then introduce new drills.
