5. TARGET HEART RATE ZONE
The target heart rate zone is a range between the lower
and upper heart rate limits expressed as percentages
of the maximum heart rate (%HR
max
) or as beats
per minute (bpm). HR
max
is the highest number of
heartbeats per minute during maximum physical
exertion.
Where you have set the age of your student on the
wrist unit, the limits are calculated using the following
formulas:
220 - the age of the student = HR
max
.65 x HR
max
= lower limit
.85 x HR
max
= upper limit
For general activities, the zone between 65% and
85% of HR
max
has a positive effect without being too
strenuous on the heart and aerobic fi tness of children.
The limits can be changed using UpLink Tool software
or manually in the Settings menu.
You can also set the target heart rate zone as 130-170
bpm, which is an average zone for all children based
on the estimated maximum heart rate of 200 bpm. In
this case you do not have to change the limits for each
student even if their ages vary. The limits can be set
by using UpLink Tool software or manually.
