About

HRV Team

Features
Read full description

HRV Team is an extremely powerful and highly specialized tool that helps an instructor improve team performance under pressure. Unlike most heart rate variability apps, HRV Team does not use a number, or metric, to represent heart rate variability. Instead HRV Team displays the beat-by-beat heart rate in way that is easy for instructors to use to guide training. Instructors can follow the moment-by-moment stress response of each team member and give them immediate feedback. By recording the heart rate of each member superimposed on the camera view of the iPad, team members can review their performance afterward and receive detailed feedback on their use of techniques to improve performance and resilience. HRV Team has the following capabilities: ⁃ displays the heart rate from each student in a training session simultaneously (7-10 student recommended maximum in a session) ⁃ display settings can be changed to vary heart rate and time scale and to zoom in on one student if desired ⁃ offers the option of recording audio and video simultaneously with heart rate ⁃ can display heart rate tracings superimposed over the camera view ⁃ saves the heart rate data for later review ⁃ saves any recordings made for later review ⁃ heart rate data can be emailed as a csv file for further analysis ⁃ video recordings can be exported to Photos NOTE: HRV Team has been tested with the following heart rate monitors: Zephyr HxM Smart, Polar H7, FirstBeat. Other monitors may not function with the app. You will need to purchase a heart rate monitor separately. HRV Team is meant to be used by instructors familiar with stress, resilience and heart-rate changes under stress, such as those taught by Ibernetics or by the International Performance Resilience and Efficiency Program, www.proresilience.org. HRV Team can also be used by those who are familiar with teaching HRV biofeedback. HRV Team developed by Ibernetics, LLC iOS programming by Owen L Brown at www.back-40.com
