Career
Santos represented Brazil at the 2008 Summer Olympics in Beijing. She competed at the 4x100 metres relay together with Lucimar de Moura, Thaissa Presti and Rosemar Coelho Neto. In their first round heat they placed third behind Belgium and Great Britain, but in front of Nigeria.
Their time of 43.38 seconds was the fifth time overall out of sixteen participating nations.
With this result they qualified for the final in which they sprinted to a time of 43.14 seconds and the fourth place behind Nigeria, missing out on the bronze medal with 0.10 seconds. At Daegu 2011, Rosangela went to the 4 × 100 m final, ranking eighth - with a new South American record (4292) at the preliminary.
At the 2012 Summer Olympics, Rosângela went to the semifinals of the 100m, with a mark of 11.07 s, which just was not approved as a South American record due to +2,2 wind (the maximum allowed for approval of record is +20). Still in London, the Brazilian 4 × 100 m relay women team, composed by Ana Cláudia Lemos, Franciela Krasucki, Evelyn dos Santos and Rosangela Santos broke the South American record in the qualifying of the race, with a time of 42.55, and went to the final in sixth place.
In the final, the Brazilian relay did 42.91 and finished 7th.
At the 2013 World Championships in Moscow, the team composed by Ana Cláudia Lemos, Evelyn dos Santos, Franciela Krasucki and Rosângela Santos broke the South American record in the semifinals of the women"s 4 × 100 m metres relay, with a time of 42.29 seconds. But, strangely and without official explanation, the CBAT (Brazilian Athletics Confederation) held a bizarre athlete change to the final, putting Vanda Gomes (who had never run the relay) instead of Rosangela Santos, to close the race. Santos has dual citizenship American and Brazilian.
