Sports and body motion

Ive recently been looking into the effect that using body motion along side Slow Shutter has. I find this really interesting, i like the ghostly effect which can be achieved through this method and how the camera seems to pick up movement , they almost seem to allow the viewer especially in cases such as photographing dancers and sport to see the course of the movements taken giving the viewer an almost visual story into the past and present of that photograph.
I've also been asked to take some photographs for the university newspaper for sports week, would love to somehow incorporate this into my work.
