Description
HRV4Training is also the first app that goes beyond simple measurements and provides insights on 1) acute or day to day HRV changes in response to training 2) long term multi-parameter trends to look at the big picture 3) correlations between physiological measurements and annotations 4) training load analysis, fitness, fatigue, readiness to perform and injury risk. All data is processed inside the app in order to provide you with actionable interpretations that can help optimizing your training plan and performance.
Main features:
– HRV-based advice helps you to adapt your trainings based on objective measures of recovery
– Advanced insights on both short term acute responses to training and long term multi-parameter trends to better understand the big picture
– Training load analysis: pick the metric most representative of your trainings (e.g. TSS, Suffer Score, training distance or your own custom metric) and analyze fitness & fatigue, determined as chronic and acute training loads, as well as readiness to perform and injury risk.
– In app Correlations analysis between HR/HRV and annotated Tags
– TAGS: lets you tag your sleep, mental energy, muscle fatigue, stress and all other parameters that can help you understand what is influencing your physical condition and physiological stress
– Works with Bluetooth SMART heart rate monitors (a Polar H7 is recommended) or simply your phone's Camera
– Configurable test (single or orthostatic, choose test duration between 1, 3 or 5 minutes)
– Configurable paced breathing to improve test reliability (choose between 6, 8 and 10 breaths per minute)
– Extracts and stores the following features while lying down and/or standing: heart rate, mean of beat-to-beat intervals (AVNN), standard deviation of beat-to-beat intervals (SDNN), square root of the mean squared difference of successive R-Rs (rMSSD), number of pairs of successive R-Rs that differ by more than 50 ms (pNN50), low frequency power (LF, 0.04-0.15 Hz), high frequency power (HF, 0.15-0.40 Hz)
– Shows the PPG signal view to ensure signal quality during the test if the camera is used instead of a bluetooth SMART sensor
– Lets you annotate your training days and training intensity to provide more accurate analytics on how your trainings impact your physical condition
– HRV4T Recovery Points to provide a single, straightforward metric to analyze your physical condition
– Population summaries and people like you comparisons to put your data into perspective
– Analysis of compliance and consistency
– Trends to look at the bigger picture
– Custom analysis on the relation between trainings and HRV
– Integrates with the Health app (writes heart rate)
– Data export via email or Dropbox
– RR-intervals correction
– Integrates with TrainingPeaks, SportTracks, Genetrainer (push data) and Strava (retrieve your trainings)

HRV4Training requires an iPhone 5 or later if you are using the camera version, since iPads do not allow to properly fire up the flash, which is needed for PPG acquisition.
HRV4Training requires to register an account with your email address, so that your data can be backed up safely and retrieved in case anything happens (app issue, changing phone, etc.).
