Resonant Breathing Biofeedback Training for Stress Reduction Among Manufacturing Operators

Abstract The aim of this study was to examine the effect of resonant breathing biofeedback training for reducing stress among manufacturing operators. Resonant breathing biofeedback works by teaching people to recognize their involuntary heart rate variability and to control patterns of this physiological response. Thirty-six female operators from an electronic manufacturing factory were randomly assigned as the experimental group (n = 19) and the control group (n = 17). The participants of the intervention received 5 weekly sessions of biofeedback training. Physiological stress profiles and self-perceived depression, anxiety, and stress scale (DASS) were assessed at pre- and post-intervention. Results indicated that depression, anxiety, and stress significantly decreased after the training in the experimental group; they were supported by a significant increase in physiological measures. Overall, these results support the potential application of resonant biofeedback training to reduce negative emotional symptoms among industrial workers.The aim of this study was to examine the effect of resonant breathing biofeedback training for reducing stress among manufacturing operators.

Effect of biofeedback training on operator's cognitive performance

BACKGROUND Predominantly cognitive tasks assigned to the shop floor can lead to decreased cognitive functions problems, thereby increasing occupational accident risks. A potential approach to prevent such circumstances is by improving operators cognitive performance. OBJECTIVE This study aimed to examine whether heart rate variability (HRV) biofeedback training could improve cognitive performance among electronic manufacturings operators. PARTICIPANTS Subjects consisted of 36 female operators who were randomly assigned as the experimental (n=19), and control group (n=17). METHOD The experimental participants received five session of weekly HRV biofeedback training of 30-50 minutes each. Physiological stress profiles and cognitive performance were assessed at pre and post-intervention. RESULTS Significant group x time effects were observed for attention and memory (p< 0.01) but not present for cognitive flexibility. Significant higher total spectrum HRV and low frequency (LF) power also occurred during biofeedback sessions, in addition to slower respiration rate. Physiological stress profile showed that the biofeedback participants were able to increase their LF activity at baseline, stressor, and recovery periods from pre to post. CONCLUSION This study demonstrates potential application of HRV biofeedback for operators performance enhancement, associated with increases in HRV.

The effectiveness of biofeedback training among university students

University students need some support program to improve the academic performance. Biofeedback training is one of the effectiveness programs to help students handling the problem regarding of their study process. In this research, the biofeedback training to manage study anxiety in order to increase academic performance among students is proposed. The research was selected for 12 participants. They are divided into two equal groups, the experiment and the control groups. The training runs on six sessions with the experiment groups received full training and no training of the control groups. The result shows that the experiment groups perform better in reducing anxiety levels as well as increase academic performance than that the control groups. Based on these results, biofeedback training can be concluded as an effective program to improve academic performance among university students. Therefore, the participants should be practiced the techniques to get the intensive level in mastering regarding of managing study anxiety and improving academic performance.
