Improved Sympathetic Activity With Short-Term Effects of Yoga in Young Adults.

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.

Increased afternoon step count increases heart rate variability in patients with cardiovascular risk factors.

Aims And Objectives: The present study investigated whether morning or afternoon activity is more effective at increasing the high-frequency (HF) index, a parasympathetic index, in patients with cardiovascular risk factors.

Background: A decreased HF index, a heart rate variability (HRV) parameter, is a well-established marker of poor cardiovascular prognosis. Because blood pressure and sympathetic tone are higher in the morning, physical activity and exercise in the afternoon has been recommended for patients with cardiovascular diseases.

Evaluation of quality of life among patients with ischemic heart disease who practiced self-care activities at home after elective percutaneous coronary intervention.

The present study compares health-related QOL between patients who practiced self-care activities comprising exercise and diet at home for at least 6 months (SA group; n = 84) after elective PCI and those who did not (NA group; n = 54). Health-related (HR) QOL was measured using the SF-36 questionnaire. Scores for two mental and three physical parameters of the HRQOL were increased in the SA, but not in the NA group.
