Heart Rate Control
Note: This workout requires the user to wear a 5 KHz Polar
®
or compatible heart rate transmitter
belt. The Heart Rate Control workout (HRC) cannot be selected on the control console unless it
detects a heart rate signal. The HRC workout will not work with the cardio touch contact heart
rate system.
After selecting the HRC workout, the treadmill will prompt you for workout time, weight, age, and target
heart rate. Your age is required to estimate the proper range of heart rates. The target heart rate is
calculated by the formula: 208 - (0.7 x Age). You will then have the option of adjusting the suggested
target heart rate selected either up or down. Select a target heart rate which will allow you to exercise
comfortably and safely while at the same time allowing you to reach your training goals. If you are unsure
of what to select as your target, consult your physician or a physical training professional, After starting
the HRC workout, the treadmill will attempt raise your heart rate to your target within 3 to 5 minutes.
The treadmill will emphasize using elevation of the treadmill deck first to achieve higher workloads and
thus higher heart rates; this is done to maximize the use of a walking gait, which is safer and more
comfortable for many users. As a result, many users will spend nearly the entire workout at elevation
up to 12% grade. After reaching your target, the treadmill will attempt to keep you there within 5 beats
per min. As you tire, the treadmill will compensate by reducing elevation, speed or both. A two-minute
cool-down is built in at the end of the workout.
Method of HRC workout:
User selects heart rate target in the initial start of workout or accepts the suggested target of the formula:
208 - (0.7 x Age). This target heart rate is extremely important for more reasons than just the
establishment of the target itself. It also makes an assumption of the general fitness level and controls
several aspects of how quickly the elevation and speed will be adjusted. As an example, the starting
speed for a selected target of 120 bpm (beats per minute) will be 2 mph. The starting speed for a selected
target of 140 bpm will be 3.5 mph. In between those selected targets the starting speed will be proportional
to the difference between 2 to 3.5. The workout will also be modified depending on what the selected
target is at the start of the workout. This means someone with a higher selected target will get faster
changes in speed and grade than someone with a lower target. This has the effect of getting the more
fit user to their selected target faster without overshooting the target for someone with a lower fitness
level. After the starting speed is attained by the treadmill, it will then increase the elevation every 15
seconds up to 12% grade or until the computer senses that the user is getting close to approaching
their target heart rate. Since the control is somewhat predictive in nature, it will leave ample room for
the user's heart rate to catch up to the increasing load. If the target heart rate is not attained at the load
level of the start speed at 12% grade, then the treadmill will start increasing speed every 15 seconds
up to 4 mph or until the computer senses that the user is getting close to approaching their target heart
rate. If the user is still not at the target, the treadmill will increase speed to 5 mph and drop the elevation
down to 8% grade. This is done because the speeds between 4 and 5 are difficult for the user because
it is too slow to jog and too fast for many to walk. The drop in elevation compensates somewhat for the
larger increase in speed. The system will then increase the speed of the belt every 15 seconds up to
the maximum speed of the treadmill or until the computer senses that the user is getting close to
approaching their target heart rate. At any time if the users heart rate exceeds the target, the load will
