Think about all the mechanics that go into an action in any sport. The anticipation needed to generate power. The arc of the movement. The weight shift. The follow through. The settle. Try and incorporate all the principles into your piece of animation.
Remember to plan your animation out before you start animating. If you cant shoot yourself, check out youtube.com or bbcmotiongallery.com. there should be an overwhelming amount of reference material for you to use.
Most of all have fun. Pick your favourite action of your favorite sport. If you havent checked out the goofy playing sports clips youtube that and there is an abundance of inspiration to be found.
Have fun animating!
