Brain and Body in Sport and Exercise: Biofeedback Applications in Performance Enhancement by Boris Blumenstain,Michael BAR-ELI,Gershon,Tenenbam
I’ve read it. Fairly easy to read book with some interesting ideas in it. I think for biofeedback though you really need to try it for yourself to understand what you are doing. “Getting started in Neurofeedback” is also good. If you want to know about it for sports performance go see Sue Wilson from York University and do a course with her.
