She is a Samoan lady by the name of Savanah Sanitoa.
Her speciality is the shot put (hence her build) but she failed to qualify for the championships in that event and instead took the opportunity of a wild card to represent her country in the 100 metres..
She failed to qualify from her heat, finishing in 14.23 seconds. But remarkably she was not the slowest competitor in the event. That dubious honour went to Tioiti Katatu of Kiribati, who clocked 14.38 seconds.
