Basic pole vaulting rules:
Pole vaulting is a track and field event in which a person uses a long, flexible pole (which today is usually made either of fiberglass or carbon fiber) as an aid to leap over a bar. During the approach the pole vaulter sprints down the runway in such a way as to achieve maximum speed and correct position to initiate takeoff at the end of the approach. The swing and row simply consists of the vaulter swinging his trail leg forward and rowing the pole, bringing his top arm down to the hips, while trying to keep the trail leg straight to store more potential energy into the pole, the rowing motion also keeps the pole bent for a longer period of time for the vaulter to get into optimum position.

Running with a large pole towards a stationary object with the intention of somehow flinging your body over another pole held high above the ground is not in my repertoire. But somehow these amazing athletes are able to accomplish this feat. It takes a lot of muscle, being able to run fast enough to get even a little bit off the ground, definitely their abs and probably their arms.
Ladder Running
From what I can gather, the racers line up and wait for the gunshot. Then they run full-speed towards a wall, launch the ladder up to the first ledge, and climb as fast as they can. They then proceed to sit on the ledge, throw the ladder up to the next ledge and repeat the process.
They basically use the same strength because although in ladder running they throw up a ladder instead of their bodies, they still have to do it three times. Plus they also have to climb up it as quick as they can. The two sports seem to even out. We should commend them for their speed and strength.
