I assume you mean a PL meet. I've never competed in that, so I can't say. I can tell you this, my wife is training to be a massage therapist. According to her(and I'm not saying she is an expert), if you do any massage, make sure it is a licensed massage therapist, and communicate to him/her why you are getting the massage(ie, pre-event relaxation, whatever).
Make sure you get an athletic pre-event massage(or whatever teh actual name is). What this does is loosens you up a little, and gets the blood flowing. You don't want any kind of deep massage before any kind of athletic event, since it will interfere with power production and strength levels.
