Heartrate Control (E3 View Monitor Option) - CYBEX 525C Owner's Manual

9 - Heartrate Control (E3 View Monitor Option)

The Heartrate Control (HRC) workout requires a Polar® compatible heart rate transmitter belt (not
included).
The Heartrate Control (HRC) workout will attempt to bring the user to their target heartrate in 3-5
minutes, then keep them there for the duration of the body of the workout. A Cool Down is built in to
the end of the workout. HRC is run in Constant Power and thus defines watts.
The user selects a target heartrate, which defaults to 75% of max (max is 220-age). Limits should be
set to not allow a Target HR (THR) less than 60% of max or more than 94% of max.
The protocol starts in Stage II, with the entry point based on Target HR.
80 – 120 BPM = Step 6
•
121-127 BPM = Step 8
•
128-134 BPM = Step 10
•
135-up BPM = Step 12
•
A running pulse-to-pulse BPM value is continuously measured.
Every 15 seconds the user's pulse rate is sampled and a prediction function is evaluated (decision.)
This is subtracted from the target heartrate to form an error value which is scaled and added to the
current load value. There is a maximum rate of change of 15 steps per decision.
The workload equates to the speed of the workout. A chart of Step and Watts has been created. It has
four defined stages:
Stage 1 ramps the load from Step 1 to Step 5.
•
Stage 2 ramps the load from Step 6 through Step 18.
•
Stage 3 ramps the load from Step 19 through Step 39.
•
Stage 4 ramps the load from Step 40 through Step 100.
•
The user has limited control over the load in that the user's selections are not permanent. At the
next decision, a new load can be chosen by the software as described above to override any user
modifications.
If the user presses the UP
