Acute Effects Of Different Inspiratory Resistive Loading On Heart Rate Variability In Healthy Elderly Patients

“The cardiovascular system is noticeably affected by respiration. However, whether different inspiratory resistive loading intensities can influence autonomic heart rate (HR) modulation remains unclear. The objective of this study was to investigate HR modulation at three different inspiratory resistive loading intensities in healthy elderly men.”


“Results suggest that lower inspiratory efforts produce higher heart rate variability. These findings represent important clinical applications because low respiratory muscle training intensities can produce greater parasympathetic heart rate modulation in this population. Thus, we should choose the most appropriate load for achieving the most beneficial autonomic effects, which are associated with reduced cardiovascular event and morbidity incidence.”
