Heart Rate Program - Spirit CT900 Owner's Manual

CHESTER TREADMILL TEST
This test has two modes: CTT Performance and CTT Prediction (of Aerobic Capacity).
CTT PERFORMANCE
CTT Performance is a 12-minute graded, treadmill walk test with a fixed speed of 6.2km/hr designed to
assess whether or not the subject can achieve the minimum recommended standard for aerobic
capacity, namely 42mlsO2/kg/min.
Procedures:
1. Check there are no medical contraindications to performing exhaustive exercise
2. Subject walks at 6.2km/hr at 0% for 2 mins
3. Every 2 mins increase gradient by 3%
4. Test is completed after 12 mins
5. Test should be stopped if subject is showing overt signs of distress and exhaustion or RPE=18+
CTT Prediction
CTT Prediction is a submaximal test designed to predict aerobic capacity
1. Same walk protocol as CTT Performance but wearing HR monitor
2. Test is stopped when the subject reaches 80%HRMax or RPE=14
3. A VO2 score is given at the end of the test

HEART RATE PROGRAM

Heart Rate Control (HRC) uses your treadmill's incline system to control your heart rate via information
from pulse grips or wireless chest strap. Increases and decreases in elevation affect heart rate much
more efficiently than changes in speed alone. The HRC program automatically changes elevation
gradually to achieve the programmed target heart rate.
Selecting a Heart Rate Control Program:
You have the option, during the setup mode, to choose either the Weight Control (HR 1) program or
the Cardiovascular (HR 2) program. The Weight Control program will attempt to maintain your heart
rate at 60% of your Maximum Heart Rate. The Cardiovascular program will attempt to maintain your
heart rate at 85% of your Maximum Heart Rate. Your Maximum Heart Rate is based upon a formula
that subtracts your age from a constant of 220.Your HR setting is automatically calculated during the
setup mode when you enter your age.
Heart Rate Control Programming:
1. Press HR button to enter heart rate program.
2. Now the window will show PRESS ENTER TO MODIFY OR START TO BEGIN WORKOUT. You
can either press the Enter button for settings or press the Start button to execute the program.
3. When the Enter button is pressed, the Message Window shows PRESS 1 OR 2 TO SELECT
THEN PRESS ENTER.
At the same time, the dot matrix window is showing "1" and you can press numeric keypad 1 or 2
and then the Enter button.
4. Now Message Window is showing ADJUST TIME THEN PRESS ENTER with Time Window
blinking. Use Up/Down keys or numeric keys to adjust. After setting time, press the Enter button
again.
5. Now Message Window is showing ADJUST AGE THEN PRESS ENTER with Incline Window
blinking. Use Up/Down/ Fast/Slow keys or numeric keys to adjust. Adjusting age will change THR
value (as the THR formula described previously). After age is set, press the Enter button again.
