The England international made his return to first-team action for the Gunners in recent weeks after spending more than nine months on the sidelines with a knee ligament problem.
And in a Twitter Q and A with Arsenal’s website on Thursday morning, Walcott revealed that he is now faster than ever.
“I’ve been clocked faster than I was before when I was fit, so yes the answer is,” said Walcott.
Walcott was on Thursday called up to Roy Hodgson’s England squad for the games against Slovenia and Scotland later this month.
He has so far only played 10 minutes of first-team football for the Gunners this season.
