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.
