PURPOSE: To examine the effects of a 4-week biofeedback intervention on coherence, psychological, and performance variables in collegiate student-athletes. METHODS: Thirteen student-athletes were randomly assigned to the intervention (one weekly biofeedback session for 4-weeks) or control group (no sessions). Data were collected at pre and post-intervention using weekly averaged coherence scores, psychological measures for depression, arousal, stress, resiliency, and performance outcome measures. RESULTS: A 3 (Time) x 4 (Week average) repeated measures ANOVA was independently conducted to examine differences between time and weekly coherence average for coherence scores. No significant differences were found for “at rest”, pre, or post-practice coherence scores. A 2 (treatment group) x 4 (Week) repeated measures ANOVAs were independently conducted to examine differences between treatment groups and week average for performance, resilience, and recovery. Significant differences were found for performance by time (p = .029). For the psychological variables, 2 (treatment group) X 2 (Time) repeated measures ANOVAs were independently conducted to examine differences between treatment group and time for CESD, AD-ACL, CSSS, and the ASSQ sleep score and no significant differences were found. CONCLUSIONS: Overall the biofeedback intervention did not improve coherence, psychological, or performance variables between the groups. While the biofeedback intervention did not show significant changes in this pilot study, there is potential for future research to address male participants and a change in timing during the season.
