Liesette Bruinsma, who narrowly finished fourth in that final, has protested against the course of the competition.According to the visually impaired Frisian, she was hindered during her race by the Chinese swimmer, Li Guizhi, who tapped second. The Chinese came with her arm three times over the intermediate swimming line, which caused Bruinsma to change direction in her orbit and in turn ended up with her arm in the swimming line again, is the explanation of the protest.National coach of the swimming team Sander Nijhuis: “The regulations allow to protest in the event of significant hindrance. That was clearly visible in this case. We were ultimately in the right. We now have to wait and see when the final will be swum over.”
