SPM: It stands for
“
Steps Per Minute
＂
, and represents the number of steps the runner takes in a minute.
The
SPM
is a useful index that helps you maintain the running rhythm right for you.
SPM Function (P. 14)
By sensing with the built-in sensor the acceleration generated in the runner
’
s body during running, this watch
measures the number of steps taken, and converts it into the SPM data (the number of steps taken in 1 minute).
It also enables you to control the exercise intensity during running. Using the SPM data and the data measured
with the 1/100 sec. chronograph function in combination, you can run at different paces, either faster or slower
than usual, as desired. During the chronograph measurement, the watch displays, besides the current time, the
SPM, lap time, split time, and other running data, which is stored in memory as
log data*
after the measurement is
over. The number of steps data is accumulated on a monthly basis, and up to 12 months of such data is stored in
memory.
* Log data:
The data measured in each run is stored in a set in memory, and can be re-
called run by run. For details, see P. 17.
To find the exercise intensity right for you
By focusing on the relationship among the
“
SPM
＂
,
“
speed
＂
, and
“
physical load perceived
＂
during run-
ning, you can find the exercise intensity optimum for
you, and it will make your running training far more ef-
fective.
To control your running pace easily
during a race
Knowing the SPM while you are running a race
will prevent you from overpacing yourself in the
first half and slowing down abruptly in the latter.
To run the uphill road more skillfully
Run the uphill road rhythmically by adjusting your
stride so that the SPM obtained on the level road
can be maintained. You can run up the slope ef-
ficiently with less effort.
To check the change in your running
pace in real time
To minimize the change in your running pace, it
is necessary to know the change and adjust the
pace immediately. By checking the SPM dis-
played in real time on your watch, you can know
when to struggle, and when to slow down.
To check the progress of your running
with your own eyes
If the SPM decreases when you run the same
distance at the same pace, this means you have
acquired a dynamic running form with longer
strides. You can check the progress of your run-
ning by checking the SPM displayed on the
watch.
