Biofeedback Use In Sport, Kendra Nelson Ferguson

Electronic Thesis and Dissertation Repository

The general purpose of this dissertation was to examine the effects of biofeedback training on sport performance. This dissertation was divided into three studies. Study 1 qualitatively explored athletes’ perspectives of biofeedback post-intervention. Five varsity athletes were provided with a five-session biofeedback intervention training respiration rate, heart rate variability, and skin conductance. Following the intervention, an interview was conducted. Athletes perceived biofeedback to enhance self-regulation skills both in sport and academics, contributing to perceptions of superior performance.

To further examine perspectives of biofeedback training, Study 2 qualitatively explored mental performance consultants’ use of biofeedback and their perceptions of the tool. …

The Effectiveness Of Neurofeedback And Heart Rate Variability Biofeedback For Individuals With Long-Term Post-Concussive Symptoms, Marquise Bonn

Electronic Thesis and Dissertation Repository

Case studies have shown that low resolution electromagnetic tomography (LoRETA) neurofeedback is effective for many psychological disorders, but it’s effectiveness for individuals experiencing persistent post-concussive symptoms (PPCS) is uncertain. Individuals with PPCS (n = 7) received an eight-week LoRETA neurofeedback and heart rate variability biofeedback intervention. Change in symptoms, driving simulation performance, electroencephalographic z-score deviations, and heart rate variability were compared to PPCS (n = 9) and healthy (n = 8) control groups. Statistical analyses revealed that the intervention significantly reduced electroencephalographic z-score deviations (p < 0.005) compared to PPCS controls. Additionally, headache, nausea, and dizziness symptoms were reduced in the intervention group (p = 0.003) and the PPCS controls (p = 0.001) compared to healthy …
