The technology of biofeedback has great promise for sport psychology and specifically for psychological skills training. Psychological skills learned through biofeedback training can be applied in practice and competition and can lead to improved athletic performance. This chapter includes a brief literature review of biofeedback and biofeedback training and describes the current state of biofeedback research in sport and its implications for athletic performance enhancement. Further, biofeedback training models such as the Wingate Five-Step Approach and the Learning-Modification-Application (LMA) Approach, based on the periodization principle, are presented. Finally, future directions and conclusions for the integration of biofeedback training as part of athletic preparation are presented.
