The study aimed to determine whether athletes who practice biofeedback are able to self-regulate by reaching resonance frequency and gaining physiological control quicker than if practice time integrates imagery or a rest period. Intervention effectiveness (e.g., intervention length, time spent training) was also explored. Twenty-seven university athletes were assigned to one of three groups: (a) biofeedback (i.e., continuous training), (b) biofeedback/imagery (i.e., interspersed with imagery), and (c) biofeedback/rest (i.e., interspersed with a rest period). Five biofeedback sessions training respiration rate, heart rate variability, and skin conductance were conducted. A repeated-measure analysis of variance showed a significant interaction between groups over time (p ≤ .05) for respiration rate, heart rate variability, and skin conductance, indicating that resonance frequency and physiological control was regained following imagery or a rest period. Postmanipulation check data found intervention length and training time to be sufficient. Combining imagery with biofeedback may optimize management of psychophysiological processes.

这项研究旨在确定练习生物反馈的运动员是否能够通过达到共振频率和更快地获得生理控制来进行自我调节，而练习时间是否整合了图像或休息时间。还探讨了干预效果（例如干预时间，培训时间）。27名大学运动员被分配为三组之一：（a）生物反馈（即，连续训练），（b）生物反馈/意象（即，穿插着图像）和（c）生物反馈/休息（即，在穿插着休息时间）。进行了五次生物反馈会议，分别训练呼吸频率，心率变异性和皮肤电导率。方差的重复测量分析显示随着时间的推移组之间的显著相互作用（p ≤.05）的呼吸频率，心率变异性和皮肤电导率，表明在成像或休息后恢复了共振频率和生理控制。术后检查数据发现干预时间和培训时间足够。将图像与生物反馈相结合可以优化心理生理过程的管理。
