Can not racing make you rusty?

Hey sprinters. 2009 has been a year of injuries for me. This year is starting out well. I raced last weekend and was quite disappointed…in the 400M. Is it possible to add some time to your 400M time simply b/c you have not raced for over a year?

Yes especially for the 400. What I mean is that for a long race like that, it’s easy to get out of shape real quick.
