Energy drinks and HRV

A short summary of Dr Mike T. Nelson’s paper on the impact of a Monster energy drink on heart rate, heart rate variability (HRV) and ride time to exhaustion.

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)...

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...

Heart Rate Variability Monitoring in Team Sports

by Chris Black & Ben Stirling Ben Stirling and Chris Black both work in professional rugby league and have a particular interest in monitoring and physical performance, both in terms of injury prevention and strength and conditioning. Monitoring in Team Sports As...

HRV as a predictor of training performance

About me In my role as a Sport Scientist working for a Premier League football Club we are always seeking new ways to quantify and measure the condition of our players, particularly how well recovered they are and how ready they are to train.  After some extensive...

HRV, Tapering and Race Day Performance

I was looking over the HRV data of a very good age group runner the other day and noticed a couple of things that I want to share. We used the export function on the Edit screen to send 6 months worth of data to my laptop, where I employed the spreadsheet program to...

ithlete Gains Scientific Credibility

Since this is the first in the ‘Simon’s HRV blog’ series, I’d like to give an introduction. I’ve been thinking about doing an HRV blog for some time, partly because I spent over a year researching the topic whilst designing the ithlete...
