Abstract

An exercise technique having therapeutic effects. In this technique the heart rate of the individual being treated is continuously monitored and the prevailing rate is displayed as he undergoes a conditioning session constituted by successive stress-relaxation cycles forming a wave pattern. In the course of each cycle, the individual is required to raise his level of exertion, as indicated by his perceived heart rate, to a peak representing maximum stress, following which he is required to decrease his exertion until he reaches a lower relaxation limit at which a recovery response takes place. The upper and lower limits are determined by the individual'"'"'s existing capacity for exercise, and as the individual'"'"'s condition improves in the course of subsequent conditioning sessions, the limits are raised to effect further improvement.

Claims

1. An exercise technique having therapeutic effects on an individual operating an exercise machine which subjects him to stress and causes his heart rate to vary as a function of his exertion, said technique comprising:

(a) monitoring the heart rate of the individual operating the exercise machine and displaying on a visual indicator the resultant heart rate which depends on the degree of exertion;

(b) causing the individual to vary his exertion to undergo a stress-relaxation cycle in which first he increases his exertion, as indicated by the displayed heart rate, until he reaches a predetermined stress level, followed by reduction in exertion to a predetermined relaxation level as then indicated by the displayed heart rate, thereby completing the cycle;

(c) causing the individual to then repeat said stress-relaxation cycle to produce a series of such cycles during a predetermined period representing a conditioning session to provide a heart rate wave pattern indicative of the individual'"'"'s performance during this session; and

(d) recording the heart rate wave pattern to provide a record thereof.

2. A technique as set forth in claim 1, the step of monitoring the heart rate comprises, the individual wearing said heart rate monitor whose output is transmitted to a display panel on the indicator to provide a reading of heart rate that can be seen by the individual.

3. A technique as set forth in claim 1, wherein said machine is a rowing machine.

4. A technique as set forth in claim 1, wherein as the individual'"'"'s condition changes, as indicated by the recorded heart rate wave pattern, resetting subsequent conditioning session stress levels to higher values.

5. A technique as set forth in claim 1, the step of causing the individual to vary his exertion to undergo a stress-relaxation cycle comprises, setting the stress level to take into account an individual'"'"'s age and physical condition.

6. A technique as set forth in claim 1, the step in which the heart rate wave patterns are produced in successive sessions comprises digitizing and storing in a digital computer to make a diagnosis of the individual'"'"'s condition as a result of these sessions.

7. A technique as set forth in claim 6, comprising the step of storing in said computer heart rate wave patterns characteristic of chronic diseases and comparing them with the heart rate pattern of the exercising individual.
