CONTACT HEART RATE
CONTACT HEART RATE
The
StairMaster~
Momentum features a digitized contact heart rate monitoring
system. Through the use of stainless steel sensors built into the upper handles
and sophisticated software, heart rate can be checked at any time during a
workout. The heart rate is displayed on the console.
The contact heart rate system is very accurate (within 3% of the
medical standard). but its ability to detect a heart rate signal is influenced by
several factors. Movement of the muscles of the upper body produces an
electrical signal (muscle artifact) that will interfere with the detection of the
heart rate signal by the sensors. Movement of the hands while they are in
contact with the sensors also produces interference. Calluses and hand lotion act
as an insulating layer to reduce the signal strength. Also. the EKG signal gener-
ated by some individuals is not strong enough to be detected by the sensors.
Typically. these individuals account for 5 - 7% of the population. These individu-
als should opt for the
Polar~
chest strap method of heart rate monitoring. Most
people (between 93 - 95%) will not have a problem with the system provided
interference from movement is minimal.
Using Contact Heart Rate
Contact heart rate input signals are acquired only during contact
between your hands and the stainless steel sensors on the handrails. To use the
contact heart rate feature. place your hands around the handles so that your
hands touch both the top and the bottom of the sensors. After the initial contact
heart rate signal is detected. the console will enter a validation phase requiring a
good heart beat signal within 10 to 15 seconds, or unti I the system acquires a
valid signal. During the validation phase the console will not recognize telemetry
heart rate signals. The console will display a beating double heart icon that has
the inner heart colored in while searching for a valid signal. If. during exercise,
the heart rate displayed is erratic. it may be helpful to remove your hands from
the handles. wipe them and place them back on the handles. In all programs. the
heart rate is shown automatically in the display window the first time the
sensors are touched.
