biomechanics of basketball

[cc]

I am a middle school student doing a science fair project on the science
of 
basketball.  For example, how do you become an expert free throw shot
using
scientific principles, or how can you learn to jump higher using
biomechanics,etc.?
Any ideas? I have been searching gophers for information but I haven't
been able
to find anything.  Peter K. (vkoelsc at uoft02.utoledo.edu)
