Biofeedback (BF) training has been utilized with performers for years. Previous literature highlights the effectiveness of multi-week intervention protocols, but there is a lack of evidence for abbreviated interventions using portable devices and the performer\'s preference of these devices. Therefore, we investigated the effects of a brief BF intervention on mental workload, mood, arousal, and movement time and BF device preference. Participants (N = 40) were randomly assigned to one of two heart rate variability (HRV) BF interventions or a control group. Although the brief intervention did not have a significant effect on mood, movement time, or mental workload, it did significantly and positively impact perceived arousal. Overall, 12 participants (48%) preferred the EmWave desktop device, eight (32%) preferred the Inner Balance device, and five (20%) preferred the EmWave2 portable device. Results support limited effectiveness of a brief HRV BF protocol, although the dose-response effectiveness should continue to be explored.
