Higher light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) are linked to better heart rate variability (HRV), regardless of neighborhood greenness. Green environments may encourage physical activity, benefiting cardiac health.
Area of Science:
- Environmental Health
- Cardiovascular Physiology
- Public Health
Background:
- Physical activity (PA) and environmental factors like greenness are crucial for cardiovascular health.
- Heart rate variability (HRV) is a key indicator of cardiac autonomic function and overall health.
Purpose of the Study:
- To investigate the associations between physical activity (PA), residential greenness, and resting heart rate variability (HRV).
- To explore how environmental greenness influences physical activity levels across different intensities.
Main Methods:
- A population-based study of 5433 individuals using accelerometer data for PA and Normalized Difference Vegetation Index (NDVI) for residential greenness.
- Generalized Additive Modeling (GAM) was employed to analyze the relationships between PA, greenness, and resting HRV.
Main Results:
- Higher light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) showed positive linear associations with HRV.
- Men in greener areas reported higher PA across all intensity levels compared to those in non-green areas.
- Women in greener areas showed higher LPA and total PA but lower MPA, MVPA, and VPA.
Conclusions:
- Increased LPA and MVPA are independently associated with enhanced HRV, irrespective of residential greenness.
- Residential greenness positively correlates with PA, particularly for men and LPA in women, suggesting a role in promoting physical activity.
- Findings support considering urban green spaces in city planning to enhance public PA and cardiovascular health.

Pathophysiology of Cardiac Performance
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
