What are those two wide red stripes on the lower back of one of the Chinese female Olympic divers?
The red stripes on the back of the Chinese female divers might be a symbol of their flag though these details are not specified online. You can contact the Chinese Olympic team management to get more information on the symbolism of these stripes.
I've been wondering the same thing. A few others have it too
I wondered that too, I saw green stripes on the abdomen of another girl
It's tape. A lot of athletes have them like, divers, gymnaist, tennis players, ect... You usually don't notice it because its mostly skin clolored. I believe it's to help not pull a muscle.
