Finding the target heart rate zone.
To find the target heart rate zone for your students, you’ll need
to estimate their maximum heart rate (HR
max
). To do this, use the
following formula.
220 - the age of the student = (HR
max
)
For the general activities of children, a zone of 70 to 85% of HR
max
has a positive effect on their heart and aerobic fitness, without
being too strenuous.
To find the correct zone:
.70 x HR
max
= (lower limit)
.85 x HR
max
= (upper limit)
Note: If you teach children of different ages, use the average
to estimate their HR
max
, as long as their ages do not vary by
more than three or four years.
Programming the Recovery Calculation
The E600 will calculate how many beats your heart rate recovers
(drops) in a given amount of time after exertion. The rate at which
the heart can recover is a measure of one’s fitness.
1. From Time of Day display, press the upper right button two
times. Your display will read, "OPTIONS".
2. Enter this mode by pressing the red button twice and then
press the upper right button once. The top line will read,
"Recovery", with a timer in the middle and "On" or "OFF" at
the bottom.
3. Press the red button once more and the bottom row will
begin to flash.
4. Press either right side button to turn the recovery calculation
on or off. (If you choose OFF, you will not be able to set time.)
5. Lock in this choice by pressing the red button. The upper line
will now read, "RecoTime" and the minutes on the middle line
will flash.
