Autonomic nervous system activity in response to stress and cardiac coherence breathing exercise depending on body composition differences.
This study investigated the effects of stress and cardiac coherence breathing exercises on psychological and psychophysiological responses, and also determined whether these effects differed depending on body composition. The study participants included 33 individuals with a favourable body composit...

The study participants included 33 individuals with a favourable body composition in the fit group and 25 individuals with a less favourable body composition in the unfit group. Before the experiment, the participants completed psychological questionnaires to determine psychological differences at baseline. We recorded an electrocardiogram to analyze heart rate variability (HRV) for five minutes under three conditions: rest, an arithmetic task to induce stress, and a breathing exercise. This was followed by measurements of stress, anxiety, relaxation, and confidence using the visual analogue scale. Baseline analyses revealed that the fit group had lower depression, state and trait anxiety, and stress levels than the unfit group. The HRV indices of the standard deviation of the N-N interval (SDNN) and the root mean square of successive difference (RMSSD) decreased during the arithmetic task with increased stress and heart rate. In contrast, the breathing exercise increased SDNN, RMSSD, total power, and low-frequency power, reduced anxiety and stress, and increased relaxation and confidence. The stress condition and breathing exercise affected the groups differently. The fit group demonstrated a more significant increase in sympathetic activity during stress situations, followed by a greater increase in parasympathetic activity and recovery from stress during the breathing exercise. These findings illustrate that individuals with a more favourable body composition may have greater autonomic nervous system adaptability. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
