Abstract

Background: Biofeedback (BFB) is widely used to manage stress and anxiety in competitive athletes; however, its effects on cognitive domains such as attention remain underexplored. This study aimed to evaluate the impact of a multimodal BFB intervention on autonomic function and sustained attention in female volleyball players.

Methods: Twelve national-level female volleyball players were recruited and randomly assigned to either a BFB group (n = 6; Mage: 17.83 ± 0.75 years) or a control group (CG, n = 6; Mage: 17.67 ± 0.52 years) in this randomized pilot trial. The BFB group completed 15 sessions of multimodal BFB training over five weeks, while the CG received no intervention. Autonomic parameters, including galvanic skin response (GSR) and peripheral temperature (PT), were measured before and after the intervention using a BFB device. Sustained attention was assessed using the d2 attention test.

Results: ANCOVA results revealed significant improvements in PT (p = 0.020, η² = 0.673) and error percentage on the d2 attention test (p = 0.045, η² = 0.346) for the BFB group compared to the CG. Significant changes were observed in GSR, PT, and d2 attention test parameters from pre- to post- intervention following 15 sessions of BFB training in the BFB group (p < 0.05). No significant changes were observed in the CG (p > 0.05).

Conclusion: These preliminary results suggest that a 5-week multimodal BFB (GSR and PT focused) intervention may improve autonomic functions and cognitive performance in competitive female athletes. Further research with larger samples and diverse athletic populations is warranted to support or refute these findings and assess their generalizability.

Trial registration number: The study protocol was retrospectively registered at ClinicalTrials.gov (Registration No: NCT07061834) on 01/07/2025. Ethical approval was obtained from the Clinical Research Ethics Committee of Karamanoğlu Mehmetbey University prior to study initiation (Approval No: 02-2024/26; Date: 23/01/2024).

通过皮肤电反应和外周温度生物反馈增强女性排球运动员的自主调节和注意力:一项随机试点试验。
背景:生物反馈(BFB)被广泛应用于竞技运动员的压力和焦虑管理;然而,它对注意力等认知领域的影响仍未得到充分研究。本研究旨在评估多模式BFB干预对女排运动员自主神经功能和持续注意力的影响。方法:招募12名国家级女排运动员,随机分为BFB组(n = 6,年龄:17.83±0.75岁)和对照组(CG组,n = 6,年龄:17.67±0.52岁)。BFB组在五周内完成了15次多模式BFB训练,而CG组没有接受任何干预。使用BFB装置测量干预前后的自主神经参数,包括皮肤电反应(GSR)和外周温度(PT)。使用d2注意测试评估持续注意。结果:ANCOVA结果显示,与CG相比,BFB组在PT (p = 0.020, η²= 0.673)和d2注意测试错误率(p = 0.045, η²= 0.346)上有显著改善。15次BFB训练后,BFB组GSR、PT和d2注意测试参数在干预前与干预后发生显著变化(p < 0.05)。结论:这些初步结果表明,5周的多模式BFB (GSR和PT为重点)干预可以改善竞技女运动员的自主神经功能和认知表现。有必要对更大的样本和不同的运动人群进行进一步的研究,以支持或反驳这些发现,并评估其普遍性。试验注册号:该研究方案于2025年7月1日在ClinicalTrials.gov上回顾性注册(注册号:NCT07061834)。研究开始前已获得Karamanoğlu mehmebey大学临床研究伦理委员会的伦理批准(批准号:02-2024/26;日期:23/01/2024)。
