I highly recommend NOT getting it for your daughter if you aren't trolling. Let her just have fun and race and not worry about taking something she has no experience with leading into the biggest race of her life so far perhaps. Its no guarantee to work either or notice a difference at that age as you sometimes can improve a ton of time as your progress throughout the season.
I say no. Look at it this way: if it was your hypothetical 8 year-old daughter you were talking about, it would be a silly question - of course you (and she) wouldn't be taking competitions that seriously (hopefully). If it was your 22 year-old daughter, you'd presumably leave it up to them to decide and mind your own business. Your daughter is somewhere in the middle of "that's silly" and "it's up to them". She probably can't make a truly free decision because of wanting to do what is most likely to please over-involved parents.
Your best bet, for her sake, is to not even bring up this weird chemical performance aid that serves as a signal to her that this is serious business and she needs to perform. Let her just enjoy racing and having fun with her teammates, rather than trying to slowly turn her into a mental wreck.
I don’t get the overwhelming “no” responses. It is widely used in the sport. Other than a potential case of the sh!ts, which had never afflicted me fwiw, there are no adverse symptoms or side effects.
Is Bicarb worth her trying in the 1000m at her state qualifying meet?
Why not go full on PED's while you're at it. Consult local taco truck for assistance.
Because bicarb is legal and won't make your heart rate drop to 15 bpm and unalive you in the middle of the night.
How is taking bicarb any different from wearing super shoes or running on a Mondo track? You are a hypocrite if you think there are any differences and stupid if you think bicarb is the same as EPO.
First nutrition, sleep, and stress management have to be on point. If those "big three" are taken care of, there will likely be a few percentage points to gain from pre-workout powders, bicarb, etc.
With bicarb specifically, you will want to try it out before a key workout as if it were the race.
I vote no. She’s a kid, she should be practicing racing strategy and pushing herself, not learning to rely on bicarb (or caffeine, or whatever) for her kick. This is the time to practice good nutrition and training before throwing in expensive add-ons. If not using bicarb costs her a victory, let her practice losing gracefully.
