I've been wearing my fitbit charge2 for a bit over a year, of course with small pauses for charging etc. The heart rate is measured with a 1Hz frequency and a resolution of 1.
Now fitbit determines what it thinks of as a resting heart rate and some approximation of my vo2 max.
My question is: By any means of calculus, what else can we learn from this data? Are there any measures of interest that I can extract from these values? Is there any software out there to do this? I am not afraid of doing the matlab/python code myself or sharing my data.
