Abstract

A microprocessor based exercise treadmill control system is disclosed which includes various features to enhance user operation. These features include programs operative to: permit a set of user controls to cause the treadmill to initially operate at predetermined speeds; permit the user to design custom workouts; permit the user to switch between workout programs while the treadmill is in operation; and perform an automatic cooldown program where the duration of the cooldown is a function of the duration of the workout or the user'"'"'s heart rate. The features also include a stop program responsive to a detector for automatically stopping the treadmill when a user is no longer on the treadmill and a frame tag module attached to the treadmill frame having a non-volatile memory for storing treadmill configuration, and operational and maintenance data. Another included feature is the ability to display the amount of time a user spends in a heart rate zone.

Claims

1. An exercise aerobic exercise apparatus, comprising:

a mechanism for permitting a user to exercise aerobically;

a heart rate monitor for measuring the user'"'"'s heart rate;

a control system operatively connected to said mechanism and said heart rate monitor;

a control panel secured to said mechanism and operatively connected to said control system wherein said control panel includes at least one display and a set of user controls for controlling said mechanism, to permit a user to operate said mechanism for a workout; and

a time in zone program operatively connected to said control system for generating in said display at periodic intervals during said workout an indication as to how much time the user'"'"'s heart rate is in a predetermined zone.

2. The exercise apparatus of claim 1 wherein said user controls accept a target heart rate from the user and said time in zone program computes said zone from said target heart rate.

3. The exercise apparatus of claim 1 wherein said time in zone program additionally generates in said display an indication that the user is entering said zone.

4. The exercise apparatus of claim 1 wherein said time in zone program additionally generates in said display an indication that the user is leaving said zone.

5. The exercise apparatus of claim 1 wherein said control system contains a set of workout programs and said time in zone program computes said zone from said workout programs.

6. The apparatus of claim 1 wherein said control system additionally computes and displays on said display at the conclusion of said workout the percentage of time the user'"'"'s heart rate was in said predetermined zone during said workout.

7. The apparatus of claim 5 wherein said workout program is a fat burn program and said predetermined zone is approximately between 60 percent and 72 percent of a calculated maximal heart rate for the user.

8. The apparatus of claim 5 wherein said workout program is a cardio workout program and said predetermined zone is approximately between 72 percent and 84 percent of a calculated maximal heart rate for the user.

9. The apparatus of claim 7 wherein said calculated maximal heart rate is approximately equal to 220 minus the age of the user.

10. The apparatus of claim 1 wherein said predetermined zone is approximately 10 heart beats below and 10 heart beats above a target heart rate entered by the user in said control panel.
