The menstrual cycle is the entire reproductive cycle, I think that you mean menstruation/period. Gymnasts do the same as every other girl, just use a pad, tampon, or menstrual cup.
One menstrual cycle is the number of days from your first day of period up until your next period - you determine your average menstrual cycle length by figuring out the average of your last six cycles. You can also use mobile phone apps or web sites such as My Monthly Cycle to figure out your average menstrual cycle length for you.

Yes, why not, but chances are they'll be flushed out with your flow and so you do not get maximum benefit from them. My obgyn told me to stop using them during my menstrual cycle and resume when my cycle ends. I think there's a practical reason for it.
