I'm an adult with AD(H)D doing gymnastics and I've never had meds (very much don't want them for personal reasons). I'm doing well withouth them, though I also don't train as many hours. I generally try to do do 1.5hrs of gymnastics followed by 1.5hrs of strength training twice a week. and some evenings 1 hr stretching if I can find the space (it's relaxing but we lack room for it).
I wonder a bit more specifically what issues you notice with your daughter. You mention she spends time chasing bugs and readjusting her leotard. When does she do this (during explanation, when she should be doing skills, ...). Is it causing trouble? What kind of trouble. Is she understanding explanations?
I find that taking little moments in between reps isn't per se a bad thing. It prevents overexertion from too many reps in a row causing bad form. It gives the mind a moment to process things. If it's causing problems, you can always look at what specific problems it causes and why. Some stuff I've done (not just with gymnastics but in general)
- sometimes my mind "lags" for a moment as somebody explains sth to me. I just ask them "could you wait a moment? Ok thanks, my mind needed a moment to catch up". Or I ask them to repeat it later. People don't normally mind, especially
- If I need to remember what I need to do, I write it down or have it written down. Recently I helped out at a comp group, and they had long instructions of what they had to do. I'd never be able to remember all that, but there was a list of instructions we read to them. If I'd been a gymnast there, I'd have been checking that list every now and then to know what to do.
This one isn't so much for me but it may be good for your daughter: if she gets distracted before finishing her task, let her keep track of the task and reward herself when finishing. Needs to do 10 casts? Let her count them and check it off as completed when she's done it.
These are just some examples. I think in general when there's an issue with her ADHD, you could try to approach it together with her by looking at 3 things:
1. what's happening? (e.g. I forget to finish my drills because I get distracted)
2. what's the consequence? (e.g. I don't finish my exercise
3. what can we REALISTICALLY do about this? (e.g.: write down what I've done so I don't lose track.)(NOT stuff like: just focus better) realistic means it's something she feels she can achieve. not something other people think she should be able to do.
She may live with some of these challenges for a long time, so she will need to figure out how to deal with them eventually. So long as she's safe, hobbies are a great place to do this I think. Just make sure she gets to lead a bit in this because it's her hobby and it should be fun for her. (And she'll be more motivated if it comes from her). If medication is an option for her then that's great too, I'm just trying to add more ideas for her toolbox in life.
If we train at home she spends half the time chasing bugs, re-adjusting her leotard, stopping for a snack or disappearing to the toilet.
As for this, it did make me wonder why you train at home too and if she's maybe not just having ADHD but feeling a bit pressured or getting a bit burned out. It could be partly avoiding behaviour.
