Abstract
The purpose of this study was to clarify the heart rate variability (HRV) transition after a single yoga program. Participants were 22 females who were healthy university students and had never practiced yoga before. They practiced yoga while recording their HRV. Heart rate (HR), high frequency (HF; 0.15-0.4 Hz) as parasympathetic and low frequency (LF; 0.04-0.15 Hz) components were extracted, and then the LF/HF ratio as sympathetic and normalized units of HF HFnu = HF/(LF + HF) as parasympathetic modulation in autonomic activity were calculated. HR and HRV indices after yoga were divided into four 5-minute periods (after 5, 10, 15, and 20 minutes) and compared before yoga. HR and LF/HF at all periods after yoga were significantly lower than before yoga (P < .01, all). HF after yoga was not significantly changed, but HFnu after 5, 10, and 15 minutes was significantly higher than before yoga (P < .01, <.01, and =.02, respectively). The short-term effects of yoga on HRV implied a decrease in sympathetic modulation and a relative increase in parasympathetic modulation. Therefore, yoga may be used as a fast-acting alternative therapy to significantly improve sympathetic activity.
期刊介绍:
Holistic Nursing Practice (HNP), The Science of Health and Healing, is a peer-reviewed bimonthly journal that explores holistic models of nursing practice. Content emphasizes complementary traditional and holistic nursing and healthcare practices. Articles include theory-based interventions and their outcomes, including: innovations in holistic nursing practice; research related to holistic nursing practice, health care, and policy; and values and ethical-legal issues related to holistic nursing practices. The holistic approach is a worldview that emphasizes the potential for health and healing in human systems rather than on disease process and deficit.
