Calculating your Heart Rate Variability with SelfLoops

The SelfLoops HRV application calculates and displays the heart rate variability.

Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat (called R-R) intervals. For an intro to HRV see: http://en.wikipedia.org/wiki/Heart_rate_variability

The metrics calculated at the moment are: SDNN, RMSSD, pNN50, AVNN.

To use the application you need a Bluetooth Low Energy heart rate monitor. We have personally tested the application with the Viiiva, Wahoo BlueHR and Polar H7 heart rate monitors.
The Viiiva is available at our store: http://store.selfloops.com/viiiiva-heart-rate-monitor-and-ant-bridge/

If you record the session you will be able to export the data, saved in csv format, to Dropbox, Google Drive, by email etc, and open it using Microsoft Excel, a text editor, Apple Numbers.

By using the application you expressly agree that SelfLoops is not providing medical advice with this application. Please, consult or ask for the advice to your physician or other medical professionals for any health related questions.

Announcing lap support and data visualization improvements

We are constantly working to improve our advanced platform for performance analysis. Today we have introduced laps support and improvements on how the graphs show data.

You can now select the lap number and highlight the segment in the graph. For each lap we have calculated several metrics such as duration, elevation, average speed, power and cadence. You can visualize the lap in the map as well.

Regarding the improvements with the graphs, we have maximized the information visualized at glance. Furthermore, the zoom function allows to show every single data point of the activity, reaching the maximum level of accuracy possible.

Enjoy!

  • Training zones (where you spent the time during your workout)
  • graph with the current and historical Critical Power
  • the Force versus Cadence graph
  • The Fitness and Freshness graph (measures your form)
  • The Health status with weight, Functional Threshold Power, maximum and at rest heart rate
  • Historical Critical Power and Maximum Power Output (W/Kg)
Overall all that you need to analyze your performance and take the steps to improve.
