Abstract

System for effective training heart rate zone determination, the system comprising:—a training module adapted to determine target training heart rate zone based on at least one stored parameter;—at least one sensor for measuring core temperature of a user'"'"'s body during training;—at least one sensor for measuring a user'"'"'s heart rate during training;—a compensation module, which is arranged for compensating the target training heart rate zone based on said core temperature;—an indicating module adapted to compare the users heart rate to an effective training heart rate zone based on information from the compensation module and to inform the user when the heart rate exceeds or drops under the effective training heart rate zone. The invention further relates to use of such a system.

Claims

1. A system for determining an effective training heart rate zone, the system comprising:

a training module adapted to determine a target training heart rate (TTHR) zone based on a maximum heart rate of a user, the maximum heart rate being determined based on at least one parameter stored in the training module;

at least one sensor for measuring a core temperature (T_c) of the user during training;

at least one sensor for measuring a heart rate of the user during training;

a compensation module, which is arranged for compensating the target training heart rate (TTHR) zone based on an increase in a measurement of the core temperature (Tc), from the at least one sensor for measuring the core temperature, with respect to an average body temperature (Tb) at rest to determine an effective training heart rate (ETHR) zone, wherein the ETHR zone is composed of the TTHR zone having upper and lower range values increased by a temperature compensation value (C) for a current value of the core temperature exceeding the average body temperature, wherein;

C=P×

(Tc−

Tb) and wherein P is a personal compensation value representing an amount of extra heartbeats per minute of a user at rest per degree unit temperature difference between the current value of the core temperature and the average body temperature; and

an indicating module adapted to compare the heart rate of the user to the effective training heart rate zone based on information from the compensation module and to inform the user when the heart rate exceeds or drops under a range specified by the effective training heart rate zone.

2. System according to claim 1, wherein the compensation module is adapted to store at least the personal compensation value and the average body temperature at rest.

3. System according to claim 1, wherein the personal compensation value has a value between 0-40.

4. System according to claim 1, wherein the personal compensation value is determined individually per user.

5. System according to claim 4, wherein the personal compensation value is determined with a test.

6. System according to claim 1, wherein a maximum heart rate is determined by a physical test.

7. System according to claim 1, wherein the target training heart rate zone is based on at least one of the following parameters:

maximum heart rate value, resting heart rate value, physical condition, gender, age, weight, and training activity.

8. System according to claim 1, wherein the system comprises a display that is adapted to display the effective training heart rate zone and a real-time heart rate.

9. System according to claim 1, wherein the indication module is adapted to provide the user with a signal when the heart rate exceeds or drops under the effective training heart rate zone.

10. System according to claim 9, wherein the signal is at least one of the following:

visual signal, audible signal, and tactile signal.

11. System according to claim 1, wherein the training module, the compensation module and the indication module are part of an electronic device.

12. System according to claim 11, wherein the sensors are connectable to the electronic device via a wireless connection.

13. System according to claim 11, wherein the electronic device is one of the following:

a watch, a mobile phone, a music device, or training equipment; and

wherein the sensors are either connectable to, or part of the electronic device.

14. System according to claim 13 wherein the training equipment is one of the following:

a fitness device or a bicycle ergometer.

15. A method of effectively training a user'"'"'s body wherein the training includes using the system of claim 1 for effective training heart zone determination.

16. System according to claim 1, wherein the personal compensation value has a value between 10-30.

17. System according to claim 1, wherein a maximum heart rate is determined by a known function.

18. System according to claim 17 wherein the known function is:

Maximum Heart Rate=220−

Age (beats per minute).
