HRV response to stress predicts degree of sleep disturbance
Research summary of an intelligent study trying to understand the relationship between daytime heart rate variability (HRV), HRV response to periods of worry and sleep disturbance.
Research Summary: Sleep quality is related to HRV before bed
Researchers at the University of Salzburg, Austria and the University of California wanted to test the idea that if daytime heart rate variability (HRV) is strongly linked to physical and mental health, would HRV also be a predictor of healthy sleep?
Can HRV be used as a more accurate, individualized measure of training load?
This is an interesting study that suggest that HRV has the potential to deliver a sport independent comparable training load number, a goal long sought after by sports scientists and coaches.

Recent research sheds light on a vagus nerve ‘hack’ which reduces arthritic inflammation. This new evidence further backs up that an increase in your HRV through exercise can reduce inflammation.
We need your data!
Since we introduced subjective scales for sleep, fatigue, soreness, stress, mood & diet in ithlete v3.0 at the beginning of the year, we have been intrigued with the idea of seeing how these factors relate to changes in our daily HRV. We included a facility in the...How accurate are consumer pulse sensors?
Not very – according to a review recently undertaken by CNET. Senior Editor Sharon Profis collaborated with Cardiologist Dr Jon Zaroff to compare some popular health tracker devices to medical ECG equipment at rest and during treadmill exercise at quite high...Energy drinks and HRV

HRV after exercise: implications for training prescription
Introduction Researchers Jamie Stanley & Jonathan Peake from the University of Queensland, with the guidance of heart rate variability (HRV) sports research supremo Martin Buchheit have put together an important review article with over 120 references. The paper...Validating the new ithlete Finger Sensor
Although ECG signals have been the gold standard for heart rate variability (HRV) due to the sharp, easily identified peak of the R wave, there has been a desire amongst researchers and practitioners to find a more convenient alternative. The pulse sensor, of the...Breathing and heart rate variability: The Research
The impact of breathing on different HRV measurements: implications for monitoring athletes Who, what & why? It has long been known that breathing affects heart rate variability (HRV). Many studies have tracked HRV in athletes – some have used free (spontaneous)...Training adaptation & HRV in elite endurance athletes: Opening the door to effective monitoring
Simon Wegerif looks at the latest HRV research review, Training adaptation & HRV in elite endurance athletes: Opening the door to effective monitoring.
Measurement of HRV
Early measurement of HRV Although irregular heart rhythms and their potential for predicting health outcomes had been noticed by Chinese medics all the way back to 400 AD, it really took the Nobel prize winning invention of the Electro Cardio Graph (ECG or EKG) by...Do fish oil supplements improve heart rate variability?
Simon Wegerif, Creator of ithlete takes a look at the latest research in to the benefits on taking fish oil supplements and how this improves heart rate variability.
