there is spruntly, in a sprunt manner; smartly; vigorously; youthfully — used by Ben Jonson in 1616 and not much since then.

googling 'sprunty' seems to mostly turn up a lot of silly nicknames..

edit: google[books] does turn up this one enticing cite:
When it come bedtime, I shore wished I hadn't been so sprunty, for the blood stain was right beside my bed and I had to step over it to get in the bed at all.
