Apnea Walk

While practicing Apnea, you move around – usually you’re walking. By doing so, you increase your CO2 concentration in blood far more than by lying and relaxing. The advantage of this exercise is that you can do it actually anywhere, while shopping, walking around, working…

You can do the training with full lungs. You breathe with the full breathing. You can also do the training with only partially filled lung, then you breathe accordingly less air. You can also actively exhale. Make sure you have enough time to breathe, as CO2 accumulates in the blood.


You can save the training in the logbook. When saving, you can specify the following data:

  • Experience
    Use a star scale to indicate how easy or difficult the training was for you. 1 star means very difficult, 5 very easy.
  • Contractions
    You can specify the number of diaphragm contractions during exercise. Depending on what you want to evaluate, you can either give the total number in all rounds or the maximum number per round.
  • Pulse
    Optionally, you can specify your pulse as long as there is no interface to aheart rate monitor. Depending on what you want to evaluate, you give the minimum or maximum.
  • Lung Volume
    Since the specification of the (partial) filled lung can not be depicted in absolute numbers such as “50% filled”, you can use the slider to specify your “perceived” lung volume. Left means empty, maximum filled to the right.
  • Comment
    Free text input, which is displayed in the logbook entry.

  • In the app you can make the following settings:

    • Lap Settings
      1. Use Personal Best
        When you use your Personal Best to calculate your settings, the following values are assumed:

        Apnea Time: PB / 4
        Pause Time: PB / 4

        When you have not yet saved a Personal Best, 120 seconds are assumed. This results in the following settings:

        Apnea Time: 30 seconds
        Pause Time: 30 seconds
      2. Apnea
        Maximum time in seconds to hold breath. The time remains constant for each lap.
        No comma values are valid.
      3. Breath
        Time in seconds to breath. The time remains constant for each lap.
        No comma values are valid.
    • Feedback
      1. Haptic Feedback
        When your device supports vibration, this is used for feedback.
      2. Minute Announcement
        You decide how time is announced. Minute-accurate announcement means that the full minutes are announced. Otherwise, every 15 seconds are announced.
      3. Music Playlist
        During the training the music playlist is played in a loop.
      4. Camera Recording
        Once you have given the app permission, the training can be recorded with the camera and the microphone.
                        Playback occurs immediately after the training.
