Coherence

Description

Monitor heart rate during breathing at a preset respiratory period.</p><p>IMPORTANT NOTICE:</p><p></p><p>!!! THIS APP IS FOR EDUCATIONAL PURPOSES ONLY !!!</p><p>!!! THERE IS NO WARRANTY AND NO MEDICAL RELIANCE ON ANY DATA !!!</p><p>!!! CONSULT A DOCTOR OR A HEALTHCARE PROVIDER FOR MEDICAL ADVICE !!!</p><p></p><p>Breathing deep regular and slow will influence the heart rate known as "Respiratory Sinus Arrhythmia" (RSA) . During inhalation, the chest cavity expands and the thoracic pressure lowers thus fills the lungs with air, but also leads to a temporary lowering of arterial blood pressure. Through a mechanism called baroreflex the autonomic nervous system will respond with an increasing of the heart rate in order to keep homeostasis. During exhalation phase, the same mechanism will lead to a decreasing of the heart rate.</p>

Nouveautés

Version 1.6.0:</p><p> - Introduced RSA Scores: 0-6 bpm = Little, 6-12 bpm = Fair, 12-18 bpm = Good, 18-24 bpm = Excellent, 24+ bpm = Superior</p><p> - Respiratory period will be displayed in red with a +/- sign to signal that you should increase/decrease the period time</p><p> - The heart rate curve is normalized, so that the amplitude is always equal to the blue respiratory sinus wave, ragardless of your RSA.</p>

Great App! Developer responds to feature request and fix bugs quickly. I like the new feature with vibration so that I don't have to look at my watch while breathing. Especially I like that the strength of vibration can be set. Like this you can practice the breathing without everyone hearing the vibration signals...Maybe it would also make sense to add setting to turn off the display after some time if vibration is used for guidance. On Amoled devices it would be nice to see inverted colors (black background). I also like the new feature that allows change length of breath in/out phase. Many graphs available to analyze the data! Would it also be possible to measure how HRV changes? (rMSSD)?

Thanks for the even better review ;) The display turn off makes sense indeed on amoled. I use a memory in pixel display (fr245) therefore it was not relevant. - I first started with a "dark mode" but again on my mip display it was difficult to see details. But i already got this on my todo list. - HRV is actually not within my focus. There is a standard "stress" diagram produced by garmin that comes automatically with the breathwork activity. To calculate the RMSSD is not a big deal, but why are you interrested in this value?

This app has potential! I think it would be great to add customized breath in/out time length. I personally used 4,5 sec in and 6,5 sec out (my resonant frequency ) The sinus curve was a bit confusing for me but with 3rd trial I got use to it. I am looking forward to analyze the data in graphs. So far i haven’t seen any graph. (Maybe because my longest session was only 5 minutes?)

Thanks for your review. I will consider a customization of diffent inhalation/exhalation times. I understood "coherent breathing" as a balanced breathing method that does not prefer inhalation or exhalation with the goal to balance the autonomous nervous system (Sympathetic Nervous System and Parasympathetic Nervous System). Also the evaluation of "coherence" of heartrate to breathing in phase and waveform will be difficult. But I will consider. Moreover I noticed, that the extra graphics will currently not be shown in the app. Try the webpage https://connect.garmin.com/ to review your activity
