Logan Dooley and Alaina Williams are two of the world champion gymnasts competing in the 2010 Visa Championships.

In addition, the two trampoline gymnasts representing the USA in the 2010 Youth Olympic Games are expected to compete prior to traveling to Singapore: Hunter Brewster and Savannah Vinsant, both of Lafayette, La. The USA is also sending gymnasts in rhythmic and men's gymnastics.

All of the returning 2009 junior champions are now competing on the senior level: trampoline – Dakota Earnest of Plains, Tex., and Jeffery Gluckstein of Atlantic Highlands, N.J. (Gluckstein was also part of the synchro title team); tumbling – Kiara Nowlin of Oxnard, Calif., and Aaron Cook of Detroit; and double mini-trampoline – Alexander Renkert of Indianapolis, and Nowlin.

The entire trampoline/tumbling field, which represents 21 states, is listed below, alphabetically by state. The competitors for men's and rhythmic gymnastics were announced earlier, and the women's field will be released shortly.
