wow. Thanks everyone for the variety of responses. Im actually very glad that Im not the only one that has heard this rule, and im glad so many coaches responded. It baffles me that some of the coaches have never even heard of this rule. So i wonder where this "old wives tale" came from?!
Our gym also utilizes those waist bands, and I have always wondered what they were for. Just dont make sense to me, but as Im just a lowly parent, asking one of the coaches at the gym would be taboo. So glad someone on here brought that up.
as it were, DD does swim the day before a meet, specially if at a hotel. Then comes dinner and then bath (to wash chlorine off if pool) and bed. Sleeps very well. Has really had no problems at meet that arent there usually lol.
I dont think I would ever let her swim an hour before meet or so. as for after meet, i would wait about 2-3 hours before letting her swim so she would not get any cramps or anything.
