Since Karlha Magliocco was six years old she has been practicing sports, beginning with swimming and then soccer. At age of 12, Karlha decided to practice boxing, influenced by her mother, who is referee in Venezuela.
Her discipline led her to become the first Venezuelan female boxer to qualify to the Pan American Games. Then she made history by winning the bronze medal in Guadalajara, Mexico, 2011.
Magliocco is also the first Venezuelan female boxer who has participated in the Olympics. The International Boxing Association (AIBA) announced her qualification just after the world tournaments in China, where Karlha was placed as the second best American. In London 2012, she reached the quarterfinals.
