São Paulo. This was a
South American record. She finished tenth at the
2008 Summer Olympics with a vault of 4.50 m, however, unable to scale the heights that she had in June. During the competition, the organisers lost one of Murer's poles, causing her to underperform as she spent over 10 minutes trying to get the pole back. She improved her outdoor record to 4.82 m in June 2009 at the
Troféu Brasil Caixa de Atletismo meet. She made the jump en route to winning her fifth Brazilian championships in the event, breaking the area record for the eleventh time and placing joint sixth in the all-time lists. She competed at the
2009 World Championships in Athletics in
Berlin but she failed to match her early season form, finishing with a best clearance of 4.55 m. She improved to 4.60 m at the
2009 IAAF World Athletics Final, winning the
silver medal. where she won the gold medal At the
2010 IAAF World Indoor Championships, Murer took advantage of
Yelena Isinbayeva's failure at 4.75 m and continued at 4.80 m, clearing first time and winning her first global championships. Murer improved her indoor mark to 4.83 m at the Grand Prix in
Birmingham,
United Kingdom. She further improved her outdoor record in June to 4.85 m at the
2010 Ibero-American Championships in
San Fernando, Spain. This mark placed her as the fourth greatest pole vaulter on the all-time lists. She then attempted to vault over 4.93 m, but failed three times. She was dominant on the
2010 IAAF Diamond League circuit, winning three out of the six Diamond League race events. Her vault of 4.81 m to win at the
Weltklasse Zurich meeting made her the inaugural Diamond League winner of the women's pole vault. She was selected to represent the Americas team at the
2010 IAAF Continental Cup, and although she won the
bronze medal, her mark of 4.50 m was far from her year's best. She retained her national title at the Troféu Brasil de Atletismo, vaulting 4.70 m to bring a close to her season. In 2011, Murer became the first Brazilian to win the
IAAF World Championship, vaulting 4.85 m at the
2011 World Championships in Athletics in Daegu. Despite high expectations for the
2012 Summer Olympics, Murer did not qualify for the finals. She failed on the first two attempts for 4.55 m, and gave up on the last, complaining about unfavorable wind conditions. In 2014, Murer won the second
Diamond League circuit, winning four out of the seven diamond race events. Up until 2015, Murer's post-Olympics performances were underwhelming. Then, she earned a silver medal at both the
2015 Pan American Games and the
2015 World Championships, surpassed only by the Cuban
Yarisley Silva. In the latter, Murer reached again her personal best of 4.85 m. On 3 July 2016, she vaulted 4.87 m at the
Troféu Brasil de Atletismo in
São Bernardo do Campo, the Brazilian athletics trials to

Herculis Diamond League meet, Murer reported pain in her neck. Despite treating it, by the time of the
London Grand Prix, Murer was feeling a lack of strength in her arms. Tests revealed a cervical
spinal disc herniation, leading Murer to go through extensive physical therapy to ensure she would perform normally during the
2016 Summer Olympics at home. Still, by the time of the Games, Murer failed in her first attempts at clearing 4.55 m. She later attributed the failure on not being fully recovered from the hernia. ==Achievements==
