Biofeedback is among the various self-regulation techniques that mental performance consultants can utilize in their practice with athletes. Biofeedback produces psychophysiological assessments in real time to enhance awareness of thoughts and emotions. Quantitatively, research shows that biofeedback can facilitate self-regulation, allowing an athlete to gain control over psychophysiological responses that could be detrimental to performance. With technology becoming a widespread tool in monitoring psychophysiological states, an exploration of consultants’ use of biofeedback, their perceptions of effectiveness, and limitations of their use was warranted to qualitatively evaluate efficiency of the tool. A qualitative descriptive approach was taken through semistructured interviews with 10 mental performance consultants. Inductive reasoning uncovered three themes: positive implications, practical limitations, and equipment options. With biofeedback, athletes have the ability to develop a deeper level of self-awareness and thereby facilitate the use of self-regulation strategies intended for optimal performance states and outcomes.
