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.

简短的生物反馈干预对情绪、唤醒、心理工作量、运动时间和生物反馈设备偏好的功效

多年来,表演者一直在使用生物反馈 (BF) 培训。以前的文献强调了多周干预协议的有效性,但缺乏使用便携式设备的简短干预和执行者对这些设备的偏好的证据。因此,我们调查了简短的 BF 干预对脑力负荷、情绪、唤醒和运动时间以及 BF 设备偏好的影响。参与者 (N = 40) 被随机分配到两个心率变异性 (HRV) BF 干预之一或一个对照组。尽管短暂的干预对情绪、运动时间或脑力负荷没有显着影响,但它确实对感知唤醒产生了显着的积极影响。总体而言,12 位参与者 (48%) 更喜欢 EmWave™ 桌面设备,8 位 (32%) 参与者更喜欢 Inner Balance™ 设备,五位 (20%) 更喜欢 EmWave2™ 便携式设备。结果支持简短 HRV BF 方案的有效性有限,尽管应继续探索剂量反应有效性。
