Abstract

A heart fitness evaluation system is set up in booth form in which a participating person may have the fitness condition of his heart evaluated based on a step test protocol. Personalized data is transmitted to the system in the form of selected answers to questions proposed, and the person is classified according to such data provided for the purposes of data comparison. The person engages in supervised exercise over a timed period to accelerate heart functions. After the activity, the person'"'"'s heart is monitored to determine the recovery rate of the heart over real time. Comparison of the recovery rate is made against stored physiological data relating to heart rate recovery of classified persons, which is translated in to the fitness level of the person'"'"'s heart and displaying such results.

(b) means for instructing said person in a format of an exercise designed to increase a beat rate of said person'"'"'s heart;

(c) exercise means for engagement by said person for changing said beat rate of said heart and for monitoring a pace at which said person is performing said exercise while said person is engaged in said exercise and for maintaining said pace at which said person performs said exercise at a predetermined pace;

(d) means for monitoring said heart after said person performs said exercise for determining a recovery rate of said heart from an increased beat rate toward a slower beat rate;

(e) means for comparing said recovery rate of said person'"'"'s heart with heart beat recovery rates of persons in the same classification as said person for evaluating the fitness of said heart of said person; and

(f) said means for selecting a sex data and an age data includes means for communicating to said person at least a first question, a second question and a third question each question followed by at least two answers respectively and means, adapted to be operated by said person, for selecting one answer from said at least two answers for each question respectively, and for communicating the answers so selected for each question to said apparatus for use in classifying said person in said classification of persons.

4. Apparatus for evaluating the fitness of the heart as in claim 3 and in which said means for monitoring further includes means for processing said electric impulses into digital pulses having characteristics which correspond to characteristics which correspond to characteristics of said electric impulses and said means for processing said electric impulses includes;

(a) means for receiving said electric impulses in analog form;

(b) a first filter for filtering out relatively high frequencies in said electric impulses;

(c) a first amplifier for amplifying the filtered signal;

(d) a second filter for further filtering out relatively high frequencies in the amplified, filtered signal;

(e) means for rectifying said amplified filtered signal for providing a full wave rectified signal;

(f) an integrator circuit, a peak detector circuit, and a comparator circuit each connected for receiving said full wave rectified signal as a first input, respectively, said integrator circuit providing a first output to said peak detector as second input thereto, and a summing circuit, said summing circuit connected for receiving said first output of said integrator circuit as one input and connected for receiving a second output from said peak detector as another input, said summing circuit for providing a third output applied to said comparator circuit as a second input thereto; and

,

(g) a timer connected for receiving a fourth output from said comparator circuit, said timer for providing a timed digital signal having a frequency corresponding to the passed low frequencies of said filtered signal.

6. Apparatus for evaluating the fitness of the heart as in claim 5 and in which said exercise means further includes means for indicating to said person that said person should speed up the pace at which said person is stepping up on said step means and stepping down from said step means, if said pace is slower than said predetermined pace and for indicating to said person that said person should slow down the pace at which said person is stepping up on said step means and stepping down from said step means if said pace is faster than said predetermined pace.
