Brazil’s reigning world champion Silvania Costa underlined her form ahead of Rio 2016 by breaking the women's long jump T11 world record at the Caixa Loterias Athletics and Swimming Championship in São Paulo.

The 29-year-old produced a superb series of leaps at the brand new Brazilian Paralympic Training Centre

All those deemed valid were longer than the previous record of 5.21 metres set by Spain's Purificación Ortiz in 1997.

Her longest legal mark was 5.34m.

"I believe this mark shows that I'm on the right path towards Rio 2016 Paralympic Games," she said afterwards.

"I had already just missed this world record, but today the conditions were great and I could pull it off."

Costa, who jumped 5.20m at the Loterias Caixa Athletics Open Championship in Rio de Janeiro in May, is one of the leading Brazilian contenders for an athletics medal at Rio 2016.

She claimed victory at both the International Paralympic Committee Athletics World Championships and the Toronto 2015 Parapan American Games last year.

Those achievements saw her named female athlete of the year at the Brazilian Paralympic Awards.
