Geisa Arcanjo

Arcanjo had significantly improved when she returned to action in 2012, setting a series of personal bests on the Brazilian circuit. She cleared eighteen metres for the first time at the 2012 Ibero-American Championships in Athletics, where she won the shot put with a personal best of 18.84 metres. After winning her first Brazilian title, she was selected for the Brazilian team for the 2012 London Olympics. Her throw of 19.02 metres in the Olympic final was enough for seventh place. She ended her season with a win at the 2012 South American Under-23 Championships in Athletics.

She began to focus on shot putting in 2010 and threw a Brazilian junior record of 17.11 m. She came fifth at the South American Games and fourth at the Ibero-American Championships. At the 2010 World Junior Championships in Athletics she won Brazil's first gold medal at the championships since 1994. However, her doping test came back positive for the banned diuretic Hydrochlorothiazide and she was later disqualified. Arcanjo said that the substance had entered her system through a green tea that she had been taking, unbeknownst to her coach. An initial judgement by the national athletics body (Confederação Brasileira de Atletismo) accepted the athlete's statement and gave her a warning rather than a ban. Brazil's sports court, Superior Tribunal de Justiça Desportiva, overturned this decision on these grounds, but upheld the warning due to the lack of enhancing impact that the substance would have on the athlete's performance. Arcanjo missed much of the 2011 season due to the length of the proceedings.

Born in São Roque, São Paulo, she started out in athletics by competing in the shot put and the discus throw. She made her debut for Brazil at the 2007 World Youth Championships in Athletics, competing in the discus. Her first international medal came in 2008, when she was the gold medallist in the shot put at the 2008 South American Youth Championships in Athletics. She also won the Brazilian youth titles in both the discus and shot. The following year she stepped up to the junior (under-19) level and had similar success, winning shot put gold and discus silver at the South American Junior Championships as well as a shot put bronze medal at the Pan American Junior Championships.
