Yes. Here is a news article related to a 15 year old that died in 2004 doing gymnastics. http://www.farragutpress.com/articles/2004/02/381.html I know of another girl Julissa Gomez who broke her neck while competing in Japan in 1988. In 1991 she never regained consciousness after she went into a coma. She went into a coma a few days later and died in 1991 without ever regaining consciousness. In 1994,Christy Henrich died due to multiple organ failures caused by her eating disorders. She was 4-foot-11 and weighed 47 pounds.
