Abstract
Cardiopulmonary interval training between a user high target heart rate and a user low target heart rate is obtained with an exercise apparatus by increasing the load of the exercise apparatus at a first predetermined rate until either the maximum machine load is obtained or the high target heart rate. When this event occurs, the load can then be maintained at a fixed level for a predetermined time. Thereafter, the load is decreased until the low target heart rate is obtained, or the user-set exercise duration expired. The heart rate of the user is monitored during the exercise. In the event that measurement of a valid heart signal is lost at any time, any increase or decrease of the load of the exercise apparatus is terminated until a valid heart rate signal is reacquired. In the case when an exercise apparatus is a treadmill, the load can be varied by increasing or decreasing both the speed adjustment and the elevation adjustment of the treadmill. In the preferred embodiment, the speed is first adjusted until a user-set maximum speed is obtained and thereafter the elevation is adjusted in order to obtain the load variations toward or from the high and low target heart rates. The exercise may be repeated between the low and high target heart rates to provide cardiopulmonary interval training.
