“…An effective measure of these RSA is the RMSSD [55]. In general, breathing changes according to posture change, and the increased breathing frequency induces a rise in HF belonging to the breathing frequency range [56,57]. Increased breathing stimulates baroreceptor reflexes present in the carotid arteries to produce RSA.…”

Objectives: In this study, we explain the role of respiratory support by proposing aHRSR, a sound stimulation to prevent imbalance of ANS due to dynamic movement. The function and role of aHRSR was analyzed through the time and frequency domain of HRV using PPG data of 22 participants (DUIRB-202109-12). Method: Changes in the ANS were confirmed using SDNN and LF, which represent total ANS activity, and the correlation between the stimulation effect of aHRSR and respiration was analyzed using RMSSD and HF, which included parasympathetic nervous system and respiratory frequency. Results : As an effect of aHRSR on dynamic movement, the recovery time of RR interval was advanced by about 15 seconds, SDNN increased from 44.16 to 47.85 ms, and RMSSD increased from 23.73 to 31.89 ms, increasing the stability of the ANS and reducing instability. Also, by reducing the change rate of LF from -13.83 to -8.83 % and the rate of change of HF from 10.59% to 3.27%, the effect of homeostasis of the ANS according to aHRSR is also shown. In other words, aHRSR decreased HF including respiratory energy and increased RMSSD generated during stimulation of the parasympathetic nervous system. Conclusions : These results suggest that aHRSR can stimulate the parasympathetic nervous system with minimal changes in breathing by assisting breathing that occurs during dynamic movement.

“…For this reason, the importance of breathing in the interaction between the respiratory and cardiovascular systems is increasing. The interaction of these systems occurs in the physical stress caused by various movements, and homeostasis is maintained through the ANS and neural networks [ 19 – 21 ]. One of these reactions, respiratory sinus arrhythmia (RSA), is a physiological phenomenon that represents a change in heart rate that occurs simultaneously with breathing and reflects the interaction between the respiratory and cardiovascular systems [ 22 – 24 ].…”

The thoracic nerves form a complex neural network that coordinates involuntary muscles such as breathing and the heart. Breathing has various patterns to maintain homeostasis in the human body. This study analyzes changes in the cardiovascular system and breathing patterns induced by stress caused by various mechanical movements performed in daily life and ultimately, the goal is to propose effective breathing patterns and breathing control methods to maintain cardiovascular homeostasis. The participants’ age was 26.97 ± 3.93 years, height was 170.24 ± 8.61 cm, and weight was 65.69 ± 13.55 Kg, and there were 62 men and 38 women. Breathing and electrocardiogram were obtained using HiCard+, a biometric monitoring device. The measured electrocardiogram was analyzed for heartbeat interval, which indicates changes in the cardiovascular system, and standard deviation of normal to normal interval (SDNN) and root mean square of the successive differences (rMSSD), which indicate the activity of the autonomic and parasympathetic nervous systems. For respiration, time changes were analyzed as patterns by calculating inspiration and exhalation times. As a result of this study, rapid changes in blood pressure increased SDNN and rMSSD from 0.053 ± 0.06 and 0.056 ± 0.087 to 0.109 ± 0.114 and 0.125 ± 0.170 s, and induced an increase in spontaneous inspiratory time from 1.46 to 1.51 s (p < 0.05). Ultimately, we hope that the results of this study will be used as a breathing control training technique to prevent and manage rapid cardiovascular changes.
