Though I am not an authority to guide someone on this aspect, yet I would like to speak out my experience on such matters.
As per SRM keeping of hair is mandatory as also covering your head when you enter a Gurdwara or when you are ( not a religious edict but a social practice/custom) in the presence of your husband's (if you are married) Male relatives who happen to be elder to your husband.
I personally do not deem it fit, girls/women, tying Turbans. A dupatta is good enough. For sports the girls can tie a scarf.
First, the SRM deems it fit for a woman to tie turban, if she chooses.

t. For a Sikh, there is no restriction or requirement as to dress except that he must wear Kachhehra (A drawer type garment fastened by a fitted string round the waist, very often worn as an underwear.) and turban. A Sikh woman may or may not tie turban.
Second point (usually overlooked). The SRM spells out the minimum that a Sikh should do. One can always choose to do more.
