Wrestling seems like exactly the wrong thing to cite here, since it's generally not done in openweight, and if you're wrestling in traditional weight classes then what's described here is hugely beneficial - you can drop a weight class but not lose strength.

> you can drop a weight class but not lose strength.

Exactly. This aligns to strategic weight cutting. Once you go up and then go back down, you feel stronger than you were for about as long as you continue regular training.

Also your opponent would have an advantage of you being lighter, which affects the results

[sfn42]

Normally in weight classed sports, people cut and dehydrate etc so that they are just inside the weight class they want to be in.

In other words, if they didn't cut they wouldn't be meeting that opponent at all because they would be in a different weight class.

Except both you and your opponent would be using tricks to be lighter (e.g. not drinking at least 1 day before the weighing)
