Additional heart rate measurements

The Philips health band measures resting heart
rate and heart rate recovery. These measurements
are not shown on the health band, but are
available in the app. Below you can find more
information.
Resting heart rate (RHR)
Resting heart rate is the rate at which your heart
beats when you are at rest. Resting heart rate
values can differ from person to person. However,
changes in resting heart rate can be an indication
of changes in your fitness level. Active people
often have a lower resting heart rate because their
heart muscle is in better condition. You need to
wear the health band for at least 24 hours before a
resting heart rate measurement can be shown.
Heart rate recovery (HRR)
Heart rate recovery is the difference in heart rate at
peak exercise and the heart rate as measured after
a one minute recovery period. The health band
measures HRR when you are exercising with your
heart rate being at least 80% of your maximum
heart rate for a minimum of ten minutes. The
measurement starts when the health band
registers change from a high-intensity activity to a
low-intensity activity. To obtain an estimate of
HRR, sit down immediately after stopping your
activity and then rest for at least 2 minutes to let
your heart rate recover. To make HRR estimates
more comparable over time, try to estimate HRR in
similar settings with respect to: time of day, type of
activity and activity duration.
Important: Do not try to estimate your HRR if you
are not very active or unaccustomed to a high
intensity activity.
