A couple years ago, at L10, my dd 'lost' her dismount. Couldn't get herself to do a double back, then couldn't even get herself to do a simple fly-away...yep....had a Jaeger and Pak...and a L4 dismount off bars
. She worked with the coach and got it back, but it took a while.
Also, I find it no surprise that this is coming up this time of year....I noticed a pattern of over 10 years in this, that the first month of school is often a stressful time in the gym...I remember my daughter commenting once 'I'm swinging bars and math formulas are going through my head." I think there is an adjustment period with perhaps a bit of brain overload trying to adjust to school and gym in the fall AND add to that the pressure at many gyms to finalize levels as registrations for meets are starting.
I will tell you, dd had no long term negative effects from struggling with her dismount that season...didn't keep her out of college or anything
. It did teach her some great life lessons though which I hope she will be using when she feels like she has 'lost' her Calculus skills
