Abstract

A fitness device (22, 37, 41) is provided with a display type readout which can be viewed by a user, and a user'"'"'s heart rate is determined to lie within a range so that the user could be required to work the equipment within that range. That range may vary with age of the user, and the "mode" of training which is itself determined by the user'"'"'s general fitness. The device (22, 37, 41) comprises a movement resistance device (25), a digital encoder (28) attached to the device which provides digital pulses, and a microprocessor (30) which is programmed to readout (14) an output as a "distance" which is proportional to the number of pulses over the time taken to travel a "distance" which is preset into the machine.

Claims

1. A fitness quantification device for an exercise machine having a stationary frame, an actuator movably coupled to said frame, and a resistance member coupled to said frame and said resistance member to provide resistance to movement of said actuator with respect to said frame, the fitness quantification device comprising:

a) a digital encoder coupled to said actuator and generating an output of electrical pulses corresponding to relative movement between said actuator and said frame;

b) a heart rate monitor worn by a user of the exercise machine during an exercise session, the monitor generating an output of electrical impulses corresponding to a current heart rate of the user, the monitor including a transmitter for transmitting impulses to a remote receiver; and

c) a programmable microprocessor including input means coupled to said digital encoder for receiving electrical pulses generated by the encoder and coupled to said heart rate monitor receiver for receiving impulses generated by the heart rate monitor;

d) a selectively actuated timer coupled to said microprocessor; and

e) a user interface means coupled to said microprocessor for input of data by the user and including a visual display for displaying a current value of said timer and a current value of an exercise parameter, said microprocessor being programmed;

i) to determine a minimum heart rate limit and a maximum heart rate limit for the user based on data input by the user; and

ii) to actuate said timer during intervals of said session wherein said input means receives impulses from the heart rate monitor receiver corresponding to a user current heart rate within the minimum and maximum heart rate limits and to disable said timer during intervals when said input means receives impulses from the heart rate monitor receiver corresponding to a user current heart rate outside the minimum and maximum heart rate limits, the current value of the timer thereby providing a measure of elapsed time during which the user'"'"'s heart rate is between the minimum and maximum heart rate limits; and

iii) to count a number of electrical pulses generated by the digital encoder during the session and to determine the current value of the exercise parameter, the current value of the exercise parameter being a function of a count of the electrical pulses generated by the digital encoder.

2. The fitness quantification device set forth in claim 1 wherein said impulses from said heart rate monitor transmitter are transmitted to said heart rate monitor receiver via rf signals.

3. The fitness quantification device set forth in claim 1 further including alarm circuitry for generating an identifiable signal if said current heart rate is above the maximum heart rate limit.

8. A fitness quantification device according to claim 1 wherein said device comprises a power supply means, a digital encoder switch and a heart monitor switch, and means for sequentially closing said switches to energize said monitor receiver and digital encoder to in turn enable said micro-processor to update said current value of the timer and said current value of the exercise parameter.

9. A method of quantifying the fitness of a user of an exercise machine, the steps of the method comprising:

a) providing a microprocessor to determine minimum and maximum heart rate limits based on physical characteristics of the user input to said microprocessor including the age and a relating measure of fitness of the user;
