Abstract

An exerciser is disclosed, of the type providing automatically controlled variations of effort levels, wherein "random" variations of effort level are included which are not predictable by the operator. The effort levels [steps] are provided in a sequence of four: the second [step] level is random; the fourth [step] level is different from the second [step value] level by half of the range; and the first and third [steps] levels are averages of the immediately preceding and immediately following [steps] levels.

Claims

1. In an exerciser apparatus, which provides variable loads to vary the energy expenditure demanded from the operator during an exercise program, the combination comprising:

means for generating a random number which is not predictable by the operator;

means for converting said random number into a corresponding value representing an energy expenditure level; and

means for developing a load resisting the operator'"'"'s energy which corresponds to said energy expenditure level.

9. The exerciser apparatus combination of any one of claims 1, 3, 4 or 5 wherein the exerciser apparatus includes a computer having memory registers, and the random-value-determining means comprises means for deriving the randomly-selected values from information stored in the computer registers.

10. The exerciser apparatus combination of any one of claims 1, 3, 4 or 5 which also comprises:

means for displaying visually to the operator the present and future energy expenditure levels over a predetermined number of time segments.

2. An exercise control method, which provides variable loads to vary the energy expenditure demanded from the operator during an exercise program, comprising:

generating a random number which is not predictable by the operator;

converting said random number into a corresponding value representing an energy expenditure level; and

developing a load resisting the operator'"'"'s energy which corresponds to said energy expenditure level.

3. In an exerciser apparatus which provides the operator with variable loads to vary the demanded energy expenditure level during an exercise program, and which has a plurality of predetermined values available for selection, the combination comprising:

means for converting each such value into a corresponding energy expenditure level;

random-value-determining means for automatically selecting from time to time random values of energy expenditure which are not predictable by the operator;

other-value-determining means for automatically selecting, and interposing between successive random values, other values of energy expenditure which have predetermined relationships to the random values; and

means for developing loads resisting operator energy which are determined by the automatically-selected energy expenditure values.

4. The exerciser apparatus combination of claim 3 wherein the other-value-determining means interposes shifted values between successive random values which are sufficiently spaced from the random values to provide an overall load-averaging tendency.

5. The exerciser apparatus combination of claim 4 wherein the other-value-determining means shifts each interposed value by approximately one-half of the available range of values.

6. The exerciser apparatus combination of either claim 4 or 5 wherein the other-value-determining means includes means for automatically selecting, and interposing between each random value and each adjacent shifted value, an averaged value derived by averaging the value of the nearest random and shifted values.

7. The exerciser apparatus combination of claim 6 wherein the exerciser apparatus includes a computer having memory registers, and the random-value-determining means comprises means for deriving the randomly-selected values from information stored in the computer registers.

8. The exerciser apparatus combination of claim 6 which also comprises:

means for displaying visually to the operator the present and future energy expenditure levels over a predetermined number of time segments.

11. An exerciser control method, which provides the operator with variable loads to vary the demanded energy expenditure level during an exercise program, and which has a plurality of predetermined values available for selection, comprising the steps of:

converting each such value into a corresponding energy expenditure level;

automatically selecting from time to time random values of energy expenditure which are not predictable by the operator;

automatically selecting, and interposing between successive random values, other values of energy expenditure which have predetermined relationships to the random values; and

developing loads resisting operator energy which are determined by the automatically-selected energy expenditure values.

12. The exerciser control method of claim 11 wherein shifted values are interposed between successive random values which are sufficiently spaced from the random values to provide an overall load-averaging tendency.

13. The exerciser control method of claim 12 wherein each interposed shifted value differs from the preceding random value by approximately one-half of the available range of values.

14. The exerciser control method of either claim 12 or 13 wherein a step is interposed between each random value step and each adjacent shifted value step which interposed step has an averaged value derived by averaging the value of the nearest random and shifted values.

15. The exerciser control method of any one of claims 2, 11, 12 or 13 including the step of deriving the randomly-selected value from information stored in computer registers.

16. The exerciser control method of any one of claims 2, 11, 12 or 13 which also includes the step of

displaying visually to the operator the present and future energy expenditure levels over a predetermined number of time segments.

17. In an exerciser apparatus, which provides variable loads to vary the energy expenditure demanded from the operator during an exercise program, the combination comprising:

means for providing a series of varied apparatus control values, the sequence of which is not readily predictable by the operator;

means for converting each such control value into a certain energy demand level; and

load-varying means for developing a series of operator energy expenditure levels, each of which corresponds to the concurrent energy demand level.

18. The exerciser apparatus combination of claim 17 wherein the load-varying means causes variations in operator energy expenditure levels primarily by varying the force exerted by the operator at a substantially constant speed.

19. An exercise control method, which provides variable loads to vary the energy expenditure demanded from the operator during an exercise program, comprising:

providing a series of varied apparatus control values, the sequence of which is not readily predictable by the operator;

converting each such control value into a certain energy demand level; and

developing a series of operator energy expenditure levels, each of which corresponds to the concurrent energy demand level.

20. The exercise control method of claim 19 wherein variations in operator energy expenditure levels are caused primarily by varying the force exerted by the operator at a substantially constant speed.
