    First time since a while with a new Suunto Smart sensor (after some monthes of use of Coros OHR arm band).

    During my first 10min warmup at constant endurance pace, I had two sharp rises of HR, for sure not realistic. Does anybody else has already had this ?

      Dieses Problem hatte ich heute zum ersten Mal. Plötzlich geht die HF um 20 Schläge nach oben.

      Mein SSB ist gerade 3 Monate alt. Schlimm.

        I owned Suunto Smart sensor in the past (5-10 years ago). While the sensor itself worked fine, the straps seemed to be very unreliable and I had to replace them every 3-6 months in order to get good quality HR data. Once a strap was getting older it increasingly produced a lot of noise such as spikes with unrealistically high HR, and the quality of HRV was very poor, which I could clearly see in Elite HRV app. Cleaning didn’t help much. Once I even ended up in emergency care because I was scared with the poor data coming out of Suunto HR sensor and thought it was real.

        I wonder if the quality of Suunto straps has improved recently? I like my Polar H10 but it may sometimes be uncomfortable in the middle of chest under the sensor and may cause a skin irritation on a longer run.

          @sky-runner hab meinen Suunto Gurt zum Glück grad per Amazon Chat zurück geben können.
          Also das hat mich echt sehr enttäuscht.
          Ich überlege ob ich mir nun einen Gurt eines anderen Herstellers kaufe.

            I have no longterm quality experience with a Suunto belt, which undeniably seem to be chafe-free, but I fixed the Polar (and previously Garmin) chafing with a sleeve made from old bicycle inner tubing. Even after a couple of hours running it then left only a slight reddening of the skin at the bottom edge:

              If the spikes only are short ones at the beginning of an exercise, like in the graph you quoted, then they most likely are from static electricity built up in a dry tech material shirt. Those spikes disappear when the shirt get drenched by sweat.

                Bei mir steigt der Puls oft um ziemlich genau 20 Schläge an nach ca 20 min im Training.

                Unterbreche ich die Aktivität und starte sie danach neu, läuft es erst prima um dann nach ca 20 min wieder einen Sprung um ca 20 Schläge nach oben zu machen. Dort hält sich dann der angezeigte Puls auch bis zum Schluss.

                Im direkten Vergleich mit meinem Corosband und von meinem Gefühl her liegt der Fehler am Suunto Band. Denn dieses zeigt mir dann bei schnelleren Läufen Werte jenseits meiner maxHF.

                Ich habe jetzt aber rausgefunden dass das Problem höchstwahrscheinlich im Gurt liegt. Denn wenn ich den Sensor auf einen anderen Gurt stecke, kommt dieser Fehler nicht.

                Schade Suunto. Den schicke ich zurück und nutze erstmal meinen sehr alten H10 wieder.

                    @sky-runner the belt for the Suunto smart sensor had been updated a few years ago and the new contact material seems to be more reliable than the old one. You can tell them apart by the color of the rounded patch around the sensor contacts (black is old, grey is new). If you’ve never used the new one, it may be worth to give it a try.

                      @halajos Ich habe den vor 3 Monaten erst gekauft. Das war das Schwarze.

                            @IceRim Thank you.

                            I used my Suunto Sensor yesterday. For the last 12 months I was using a Garmin HRM Pro. The Data I got from my Suunto Belt was horrible. Most of the time I had no Heartrate on the Watch, so I hoped it would sync afterwards, but what I got looked like this….
                            ![Bild Text](46b657fd-ec49-46e8-b00c-a3286a9836b4-image.png

                            The Workout at the end seems ok, but way to high. The running intervals at the beginning showed no heartrate at all.
