Marion Jones insisted she has done everything to clear her name after being caught up in the United States drugs scandal.
Jones jumped 6.77m in Gateshead
Jones was second in the long jump at Gateshead and reiterated her innocence before making a quick exit.
She said: "I've done everything possible to clear my name.
"I've taken a lie detector test but if people want to continue this, I will have to cope with it, and keep working to make the US team."
Jones has been linked with the Balco drugs investigation and her partner - world 100 metres record-holder Tim Montgomery - is set to reply to the United States Anti-doping Agency on Monday about serious allegations.
She added: "I've said my piece now. This is something I have to deal with but I'll get through it.
"Off the track it has been distracting, but not so much as you might think when I competing."
In Gateshead, the double Olympic sprint champion finished 10 centimetres behind Russian Tatyana Lebedeva, whose winning jump was 6.87 metres.
"Overall I am pretty happy with my performance," said Jones.
"Of course every time I compete I want to win. My fifth jump was over the
board but it was very far."
The 28-year-old added: "This will be my final competition before the US trials.
"The trials are almost as competitive as the Olympic Games and I am confident I will be okay and make the team."
