AW: HF zu hoch bei Polar wegen Trikotflattern
Wie siehts denn mit der Materialbeschaffenheit der Langarmtrikots aus? Softshell, Teflon beschichtet, irgendwas muss doch anders sein.
Da ANT bei 2,4Ghz arbeitet, erscheint mir immer noch das "Flattern" eines Trikot als unwahrscheinlich. Da der Brustgurt nur ein broadcast macht, ohne acknowledge vom
Edge, gibts leider keine direkte Fehlerkorrektur, also kein handshaking zwischen Gurt und
Edge.
Bliebe als einfachste Fehlerquelle der Gurt, der nicht richtig funktioniert oder vielleicht auch eine zu schwache Batterie hat. Ein defekter Sensor im Gurt (der nur aktiv wird, wenn angelegt) würde zB die Batterie leer zu schnell leer saugen, oder aber den Pulsschlag nicht immer erkennen und damit ständig zwischen an und aus pendeln.
Super wäre, wenn man mal ein funktionierendes Pärchen mit dem Defekten zusammen bringen könnte, um mal über Kreuz die Komponenten auszuprobieren.
Hat mir keine Ruhe gelassen und ich hab mal in US Foren gesucht, gefunden und zusammengefasst (wer kein Englisch kann babbelfish benutzen).
Ich hoffe die Infos aus dem Thread helfen weiter:
It's probably static electricity caused by your various layers of clothing rubbing together and creating false input signals to the heart rate monitor. This is an issue that generally becomes worse in the winter, when you wear more layers and when the air is dryer.
Symptoms are that it shows up more at the beginning of a ride or run, when you don't have as much perspiration in your clothing, and it shows up at higher speeds (which is why it's more of an issue when cycling).
Things you can try to minimize the problem are:
1. Make sure your strap electrodes are clean - rinse them with clear water after a ride and blot dry.
2. Moisten the strap electrode area with a bit of water or ECG contact gel before you run.
3. Lightly dampen your first-layer jersey before you put it on.
4. Rub your jersey with a Bounce (or other brand) anti-static sheet before you put it on.
5. Experiment with different clothing layers. Synthetics generally cause more HRM interference than natural fibers. Note that we're not saying you can't ride with synthetic jerseys ... different solutions work for different people, and it helps if you know when you might expect bogus heart rate readings.

This is exactly what it was. I went ahead and did an experiment this morning on the ride to work. I did not wear my synthetic top and wore a cotton T-Shirt. I wet the cotton T-Shirt and the
Garmin heart rate monitor and started the ride. The unusual spikes and high bpm were gone. I will use your suggestions for my synthetic tops and hope that this resolves the issue. Many thanks for the help....

"Buh-Bump" heartrate monitor electrode cream. Accept no substitutes.
Been using it for years. Everyone I've suggested it to has loved it if they tried it!

Simply wetting the side of the strap away from my skin when using a soft strap, or slightly wetting the front of my shirt around the strap when using a hard strap, has made these issues go away completely. No need for the hassle of gels.
My wife tried using various gels on the inside of her strap to improve the skin contact and that never had any impact. It's generally the contact with the shirt, not the skin.

This is exactly what I have found also. I tried the gells and they never solved the problem. I can actually predict which rides it will happen on based on relative humidity and the clothing choices I make.
!) Probleme. Trotz ausführlichster Wässerung habe ich laut Polar nach 15 Minuten keinen Puls mehr. Manchmal hilft es den Gurt hin- und herzuschieben, dann geht es wieder - für fünf Minuten, wenn es gut läuft. Bei eineinhalb Stunden ist das ganz schön viel Gefummel!
