What Is Behind Changes in Resting Heart Rate and Heart Rate Variability? A Large-Scale Analysis of Longitudinal Measurements Acquired in Free-Living

Excited to share our latest paper on heart rate and heart rate variability (HRV):

• 9 million morning measurements taken with HRV4Training over a period of 5 years 
  
• Population-level analysis: relationship between resting physiology (heart rate, HRV) and age, sex, BMI, and physical activity
  
• Acute stress responses analysis: relationship between resting physiology (heart rate, HRV) and training, alcohol, menstrual cycle, and sickness

This one has been in the making for a long time, and brings it all together: developing an accurate and affordable method to measure resting physiology, analyzing data at a scale that goes far beyond what we can do in the lab, and as a result, new, valuable insights
