Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method and system for managing a condition using impedance of a body composition analyzer,

The present invention relates to a method and system for evaluating and managing a condition level using a measurement principle of a body composition analyzer, and more particularly, to a method and system for measuring and managing a condition level at a time of measurement by measuring an impedance between a right arm and a left arm using a body composition analyzer To a condition management method and system using an impedance of a body composition analyzer that measures a degree of change of a body water state of an upper body after an impedance value is measured and manages a condition of a user.

In general, fatigue is a very complex symptom that manifests itself physically, mentally, and socially. It is therefore difficult to effectively assess and evaluate fatigue symptoms as a single indicator because subjective symptoms of a patient must be assessed. Fatigue symptoms are more likely to be affected than a single biomarker And have been used to evaluate fatigue by developing a questionnaire that comprehensively evaluates the contents of various dimensions.

In addition, it is difficult to evaluate stress, which is closely related to the degree of fatigue. In general, stress is when the human body is in a state of tension due to harmful factors or stimuli. In particular, the complex work environment of modern information society and the potential stress factors due to high industrialization are increasing. Stress is the cause of premature aging of the brain, persistent stress causes serious degradation of hippocampal neurons, May temporarily impair cognitive mechanisms associated with concentration, or may adversely affect autonomic homeostasis, resulting in cognitive fatigue and secondary chronic diseases.

There are many body changes to the stress response in general, but the main change is the increase in pulse and blood pressure so that more blood can be sent to the muscles, the brain and the heart first, the breathing speeds up to get more oxygen, My muscles are tense because I'm ready to do it.

Conventionally, techniques for evaluating stress include a method of analyzing the degree of stress by analyzing a change in heart rate cycle after obtaining heart rate variability (HRV) using a biometric sensor, And cortisol as an indicator, and a method of measuring an muscle fatigue using electromyogram (EMG). Here, the EMG refers to a waveform diagram obtained by deriving the action potential change that occurs at the same time as the contraction of the skeletal muscle and amplified and recorded. The normal muscle fatigue is an electromyogram measured by sensing the skin surface movement (muscle activity potential) It is a method to judge in which frequency region the spectrum of the signal is distributed and the degree of spreading.

However, in the conventional stress measurement method, there is a problem that the bioelectrical electrode must be attached directly to the body and it must be measured at a predetermined time, and there is a problem that accurate analysis is difficult due to the subjective bias of the subject in the case of the questionnaire method. In addition, the conventional method of measuring muscle fatigue takes a long time to calculate the value of muscle fatigue, which makes it difficult to measure and analyze the muscle fatigue in real time.

On the other hand, the body composition analyzer uses a bioelectrical impedance analysis method to measure a human body as a kind of resistance, and a weak alternating current is flowed to a measurement part of the human body. A potential difference at this time is detected and the resistance value is calculated. A body fat percentage or the like by a predetermined algorithm together with variables such as the height, weight, age, and sex of the subject, thereby providing information on the health status and the obesity to the subject. In such a body composition analyzer, a bioelectrical impedance analysis (BIA) method has been used for a long time in order to measure a constitutional component of the human body.

The bioelectrical impedance analysis method (BIA) sends a weak alternating current into the human body to measure the body's electrical impedance to calculate biometric information such as body fat mass, muscle mass, and body water content. As described above, the body composition analyzer generally measures a body fat by dividing a human body into an upper body part, an abdomen part, a body part, and a lower body part. The electrode includes a pair of power generation poles contacting the sole of the subject and the heel of the subject, And the impedance measuring unit is constituted by an impedance measuring circuit for measuring the bioimpedance of the subject and the control unit is constituted by a microprocess for measuring and processing the bioimpedance. Such a conventional body composition analyzer is bulky and is sold at a considerably high price, and it is difficult to purchase the public, and it is mainly used in a specific company (hospital, obesity clinic center, etc.), so that there is a problem that it can not be used for stress measurement.

Therefore, there is no known technology to measure stress and manage condition using body composition analyzer.
