wich exercises involve these muscles?

whatching this video i was surprised about the muscles in the back of the first guy...

if you stop at 8 seconds you can notice a sort of inverted V near the center of the back of the man...i know what muscles are these and how i can activate them in weigthlifting...but in gymnastic what are the exercises or the skills wich develop this type of muscles?

Here ya' go.

Pull ups for example?

yes for the latissimus dorsi the pull up...but it's the only one? you don't see these muscles on all the gymnasts!
