Comparison for Long Run
Another Comparison data ~ Long Run
I continue to compare the heart rate reading during training between the chest based sensor and the wrist based embedded sensor. Today's data is a data during long run in Garmin Training Plan for full marathon (level 1).
For detail for this training, it is 10 minutes walking and 20 minutes for a slow jogging. I did it for 3 times. Basically, the heart rate is getting high when I am jogging and getting lower when I am walking.
The result?
In a short summary, the both reading data is almost the same. However, the both sensor has a few spike during the training. There is a spike in the beginning for Forerunner 910XT with the chest band sensor. This is probably not a correct reading. I saw a similar pattern in the past training. Once it gets into stabled, I do not see such spike. One the other hand, there is no spike for the wrist based sensor reading in the beginning. So that I guess it is probably something related to the contact between the sensor and the body. Per sensor instruction, it recommends to put some moisture before wearing the sensor. I usually do not do it. Once I run a few minutes, I probably get sweatting and it would be a similar result with putting some moisture.
For the wrist based sensor, there are also spikes in the middle and the end. They are abnormally high and they are probably not a right data. Also, the reading is not very stable, the reading has a few beat moving range during the training. It is a little unstable comparing with the chest based sensor.
Anyway, the spike is very short duration and overall trend is the same. Therefore, I would think they are not big deal in normal use. I will collect more data and continue to compare the data for a while.
