Adherence
Self-reported intensity of exercise (medium/high vs. none/low) was not significantly associated with any HRV indices in older adults.
You don't need to do high-intensity exercise to improve your heart health. Focus on walking at a good pace and staying active throughout the day.

In contrast, self-reported intensity of exercise (medium/high in comparison with none/low) was not significantly associated with any HRV indices (data not shown).

More from this paper
- Higher levels of habitual leisure-time physical activity and faster walking pace are prospectively associated with more favorable heart rate variability (HRV) indices, including higher SDNN and ultralow-frequency power, in older adults.Good
- Faster walking pace is associated with less erratic sinus patterns, as indicated by a higher short-term fractal scaling exponent (DFA1) and lower Poincaré ratio, in older adults.Good
