In age group swimming meets, swimmers over the age of 18 compete in the senior or 'A' events.

Junior swimmers who are 16 to 17-years-old compete in the 'B' events while 14 to 15-year-olds participate in the 'C' category.

Dhinidhi, from Bengaluru, had become the youngest female swimmer to win seven gold medals in the National Games last year. She had also competed at the Asian Games.
