Abstract

The invention relates to a device to assist in the practice of a physical activity session by an person. The device has an electronic means for determining the real-time physical effort to be provided by said person during said session, implementing a control law having, as an output, a parameter that corresponds to the physical effort to be provided (EPF) and, as an input, data collected while the force is being applied, essentially comprising: the measurement of the heart rate (FC) of said person; the measurement of the respiratory rate (FR) of said person; and one or more indices (EVA) of strenuousness of the effort as perceived by said person, to be specified by said person during the effort, and in which said control law depends essentially on respective programmed thresholds which should not be exceeded, essentially comprising: the maximum heart rate (FC_M), the maximum respiratory rate (FR_M), and the maximum value or values associated with said index or indices of strenuousness.

Claims

1. Device (1) for assisting in the practice of a physical activity session by a subject, having electronic means for determining the intensity of the physical exertion, in real time, to be provided by said subject during said session, implementing a control law having, as an output, a parameter corresponding to said physical exertion to be provided (EPF), and, as input signals, data collected during the exertion, essentially consisting of:

the measurement of said heart rate (FC) of said subject,

the measurement of said respiratory rate (FR) of said subject,

one or a plurality of indices (EVA_x) of strenuousness of the exertion perceived by said subject, to be specified by said subject during the exertion,

and wherein the control law is also dependent on programmed thresholds, not to be exceeded, essentially consisting of;

the maximum heart rate FC_M,

the maximum respiratory rate FR_M,

the maximum value(s) EVA_xM associated with said index/indices of strenuousness of the exertion.

2. Device according to claim 1, having means for inputting the values of the index/indices of strenuousness of the exertion comprising a touch screen or a microphone.

3. Device according to claim 1, having means for learning, during a prior session or during a first phase of the physical activity session, coefficients of the control law linking the parameter corresponding to the intensity of the physical exertion to be provided, the heart rate measured, the respiratory rate measured, and the index/indices of perceived strenuousness of the exertion0

4. Device according to claim 1, wherein the control law is a robust control regulation law.

5. Device according to claim 1, wherein said device has means (2, 3) for periodically transmitting physical activity instructions to maintain the physical exertion, increase the physical exertion or, on the contrary, decrease the physical exertion of the subject in correlation with the physical exertion to be provided by said subject, determined by said assistance device at the time preceding said physical activity instruction, and the actual exertion provided by said subject at the time preceding said physical activity instruction.

6. Device according to claim 1, having means (51;

52) for recording said programmed session data and the data collected during said session with a summary in a file.

7. Device according to claim 1 any of claims 1 to 6, having means for displaying (6), in real time, said data collected during the exertion and said programmed data.

8. Physical activity apparatus (10;

20) equipped with an assistance device according to claim 1.

9. Apparatus according to claim 8, having means (41;

42) for periodically adjusting the load of the physical activity apparatus (10;

20) in order to maintain the physical exertion, increase the physical exertion or, on the contrary, decrease the physical exertion of the subject in correlation with said physical exertion to be provided by said subject, determined by said assistance device at the time preceding the adjustment, and the actual exertion provided by said subject at the time preceding said adjustment.

10. Apparatus according to claim 9, wherein said means (41;

42) for periodically adjusting the load of said apparatus comprise a controlled brake (11) or a variable-assist motor (21).

11. Apparatus according to claim 8, wherein the actual exertion provided is given by the measurement on the apparatus used for physical exercise of a resistance or assistance torque, work or power.

12. Apparatus according to claim 8, wherein said apparatus is selected from the following list:

exercise bike (10), elliptical trainer, electric bike (20), treadmill, stepper, rowing machine, weight training bench.

13. Device according to claim 2, having means for learning, during a prior session or during a first phase of the physical activity session, coefficients of the control law linking the parameter corresponding to the intensity of the physical exertion to be provided, the heart rate measured, the respiratory rate measured, and the index/indices of perceived strenuousness of the exertion0

14. Device according to claim 2, wherein the control law is a robust control regulation law.

15. Device according to claim 2, wherein said device has means (2, 3) for periodically transmitting physical activity instructions to maintain the physical exertion, increase the physical exertion or, on the contrary, decrease the physical exertion of the subject in correlation with the physical exertion to be provided by said subject, determined by said assistance device at the time preceding said physical activity instruction, and the actual exertion provided by said subject at the time preceding said physical activity instruction.

16. Device according to claim 2, having means (51;

52) for recording said programmed session data and the data collected during said session with a summary in a file.

17. Device according to claim 2 any of claims 1 to 6, having means for displaying (6), in real time, said data collected during the exertion and said programmed data.
