Smart Heart Beat / Pulse

About Smart Heart Beat / Pulse Android App

This app supports planning and analysis of a training session in the simplest manner.
The recognized indicator for the physical strain which is used is the heart rate (pulse). This is determined by means of a cardio chest strap, and is then communicated to the app via Bluetooth 4.0 LE. The app analyzes the pulse data and calculates the average, maximum, minimum and differential values of the current training session. In addition, the GPS distances* and GPS speed* are also calculated. After completion of the training session, the entire training process can be analyzed in detail and, based on the results, the next training session can be planned and stored as a training plan. An external analysis of the data is possible via the data export function.

That way, it is possible to establish a closed loop between planning, execution and analysis.


The app includes the following features:

Analysis
- Analysis diagram differential pulse analysis – 0 to 0.3 pulse beats per second -> steady training process
- Analysis diagram pulse over time
- Analysis diagram pulse limit exceeded

Planning
- Creation of a timer-based training plan – duration of a partial session, min. and max. heart rate
- Execution of the training plan, with storage of the following values:
Time
Pulse
Average Pulse
GPS speed
Average GPS speed
GPS distance

Alarm
- Min./max. alarm parameters for heart rate
- Vibration and audio signal for violation of the heart rate frequency limit
- Vibration and audio signal for re-entering the target heart rate frequency range

Display
- Current heart rate, average and max./min heart rate
- Times of optimum heart rate and times when heart rate limit was violated
- GPS distance*, GPS speed*, and average GPS speed*

* GPS data are subject to certain variations, depending on meteorological conditions, location and environment.
Due to this, significant deviations are possible. The best measurements showed a deviation from the actual distance and speed of 1%. Normally, deviations between 1% and 5% can be expected. If the signal is subjected to severe interferences by external sources, then the deviation may be as large as 10% or more. Athlete Grip can only partially correct these systematical and environmental deviations.
