Abstract

A distributive method of physical rehabilitation and conditioning using an ergometer on which exercise protocols or workouts are performed by a subject is described. The intensity and duration of the workouts are defined as the independent variables and physiological and psychological variables are measured and treated as dependent variables. The exercise protocol is stored on a portable medium and the exercise program further defines a series of successive exercise sessions conducted over time in which the same exercise protocol is repeatedly performed by the subject; and, during the performance of which protocol, physiological and psychological variables are measured. The relative changes in one or more of the dependent variables which occur over the course of the series of sessions of the exercise training program measure progress and provide the basis for modification of the exercise protocol for the next exercise training program for that subject.

Claims

1. A method of automating a process for conditioning or rehabilitating a subject utilizing an aerobic exercise training protocol based on an aerobic threshold method of exercise training performed on a polyarticular aerobic exercise device, comprising the steps of:

(a) creating a first polyarticular aerobic exercise protocol and storing said first protocol on a transportable memory device, said first protocol using a target exercise intensity (workrate) as the controlling variable, wherein the intensity and duration are related to at least one parameter selected from maximum aerobic capacity (VO₂ max) and anaerobic threshold (AT) of the subject;

(b) creating a first monitoring protocol and storing said first monitoring protocol on said memory device, said first monitoring protocol being dedicated to operate during performance of said first aerobic exercise protocol and further defining monitoring and sampling intervals for obtaining real-time data from the subject indicative of non-controlling physiological variables selected from oxygen consumption (VO₂), carbon dioxide production (VCO₂), ventilation (VE), heart rate (HR) and blood pressure (BP) and optionally psychological variables selected from the rate of perceived exertion (RPE) and compliance with the exercise protocol during each such repetitive execution of the exercise protocol;

(c) transferring the transportable memory device to an aerobic exercise device, said device being automated for operation by the transportable memory device, said device including means for measuring actual power delivered by the subject and controlling the level of subject input power required to achieve said target intensity in an automated manner;

(d) wherein the subject reproduces the exercise protocol using said aerobic exercise device through at least a first program, a program comprising repetitive execution of said first aerobic exercise protocol in a series of successive sessions;

(e) obtaining real-time data of one or more of said non-controlling physiological variables according to said first monitoring protocol during each repetitive execution of said first aerobic exercise protocol;

(f) optionally monitoring non-controlling psychological variables during execution of said first aerobic exercise protocol according to said first monitoring protocol;

(g) wherein said real-time data obtained in accordance with said monitoring protocol remains independent from the operation of said exercise device;

(h) causing selected real-time data obtained to be stored in said memory device according to said first monitoring protocol; and

(i) using changes in one or more measured non-controlling physiological and psychological variables observed over the course of said several sessions of said first program based on data stored in said memory device to evaluate progressive effectiveness of the protocol.

2. The method of claim 1 wherein the aerobic exercise device includes associated computer driven subject interface means including graphical display means and wherein the method further comprises the step of providing real-time visual interface with the subject including graphical display data feedback related to the exercise and/or monitoring protocol.

3. The method of claim 2 further comprising the step of optionally modifying the first exercise protocol to create additional sequential exercise protocols based on changes in one or more of the monitored non-controlling physiological and psychological variables over said first or another previous program.

4. The method of claim 1 further comprising the step of modifying the first or another previous monitoring protocol.

5. The method of claim 1 wherein the memory device is a transportable, remotely usable recording medium, includes means for receiving, storing and retrieving data and can be used both with a remote independent aerobic exercise device to be operated by the subject to perform the repeated protocols of the program and thereafter by an evaluator to evaluate the progress of the subject.

6. The method of claim 5 wherein the aerobic exercise device includes computer driven subject interface means including graphical display means and wherein the method further comprises the step of providing real-time visual interface with the subject including graphical display data feedback related to the exercise and/or monitoring protocol.

7. The method of claim 2 further comprising the step of monitoring compliance with the exercise protocol by monitoring the actual intensity delivered by the subject in real-time and comparing it to said target intensity at a like time in the exercise protocol.

8. The method of claim 2 including the step of displaying data of one or more of the non-controlling physiological or psychological variables to the subject on a real-time basis.

9. The method of claim 7 including the step of providing human readable output indicative of compliance with the exercise protocol by displaying in real-time a comparison of the intensity delivered by the subject in relation to the target intensity at a like time in the protocol.

10. The method of claim 2 wherein the subject interface means includes provision for real-time interaction with the subject and wherein the method includes the further step of real-time interrogation of the subject.

11. The method of claim 10 wherein the step of real-time interrogation further include, requesting subjective information of the subject.

12. The method of claim 11 including interrogation of the subject related to the subject'"'"'s rate of perceived exertion (RPE).

13. The method of claim 1 wherein said target exercise intensity value is logically related to AT and VO₂ max.

14. A computer graphic method of developing and modifying a polyarticular aerobic exercise training protocol using an anaerobic subject threshold method of exercise training and for developing and modifying a monitoring protocol for conditioning or rehabilitating a subject using dedicated software that runs on a personal computer, the protocol to be performed on a mechanized, programmable computer-controlled polyarticular aerobic exercise device, said device including means for measuring intensity of exercise by directly measuring the actual power delivered by the subject and means for controlling the level of subject input power required to achieve a target workrate in an automated manner, comprising the steps of:

(a) providing a graphic display in the form of a protocol grid of an exercise workrate v. time plot;

(b) displaying the value of a training window defined by upper and lower workrates in which maximum aerobic capacity (VO₂ max) is the upper window limit and anaerobic threshold (AT) is the lower window limit as indicia on the graphic display to act as guidelines for programming the exercise intensity of the exercise training protocol;

(c) using the graphical display to create and edit a proposed exercise training protocol of any desired complexity based on aerobic exercise duration and intensity as the controlling variable, and including a monitoring protocol having predetermined sampling intervals for recording non-controlling physiological variables selected from the group consisting of oxygen consumption (VO₂), carbon dioxide production (VCO₂), ventilation (VE), heart rate (HR) and blood pressure (BP), optionally non-controlling psychological variables selected from the group consisting of rate of perceived exertion (RPE) and compliance with the exercise protocol; and

(d) transferring to and storing a programmed aerobic exercise and monitoring protocol together with subject user instructions on a transportable, machine readable recording medium capable of interfacing with an output means and receiving and storing additional data.
