Description
Technical field
The invention belongs to human body body composition detection technique field.
Background technology
Human body mainly is made up of Main Ingredients and Appearances such as moisture, protein, bone, muscle and fat.The various compositions of quantitative measurment are called the body composition analysis.Recent years, because obesity causes more and more people's concern to healthy harm, the body composition analysis also obtains very big development.Fat weight is called obesity with the ratio of body weight above certain numerical value, may cause numerous disease.Medically, often judge the relaxed situations of disease or monitor advancing of disease by the inspection human body composition.And the obese patient measures the composition of health when adopting physical training to reduce body weight, effect that can the rational evaluation physical training.In addition, on the basis that body composition is analyzed, can diagnose the body development situation of children and adolescents and the elderly's nutrition condition, particularly for some patients, the moisture distribution of measuring the health different piece can help diagnosis and treatment disease.Concerning the sportsman of needs control body weight, judge that correctly the sportsman is lipotrophy, or muscle to increase and cause weight increase be crucial.If misjudgment will cause reducing sportsman's sport life span.For this reason, carry out the research of body analysis of components instrument and body analysis of components method, paid attention to by people day by day.
Bioelectrical impedance analysis (BIA) is a kind of do not have wound, easy, safe measuring method, and its adopts faint alternating current by human body, measures the height and the body weight of human body simultaneously.Calculate body compositions such as fluid of inside and outside cell body and body fat content according to these measurement data.
The special measurement instrument of available technology adopting bio-electrical impedance method is to design according to general bio-electrical impedance measuring method.The experimenter grasps electrode, measures the electrical impedance of health.Also there is biped to step on battery lead plate, measures the electrical impedance of health.Input experimenter's sex, age, body weight and height are analyzed body composition then before test, and the result is presented on the screen.Result of calculation has only fat weight and fat percentage, and its advantage is simple in structure, easy operating.But its testing tool is a single-frequency, and only measures the electrical impedance of body local, and the former surveys two upper limbs, and the latter surveys two lower limb.Because test specification is had limitation, its result has certain error, and is bigger to some crowd's error; In addition, experimenter or operator need import experimenter's body weight and height by keyboard.

Of the present invention according to the custom-designed detection method of Chinese ethnic group characteristics, measurements and calculations go out the accurate data of multinomial body composition apace.
The method of the invention is compared as follows with domestic and international detection method:
Japan has produced a kind of Omron body fat measuring appliance (HBF-301), and its detection method is to measure the bio-electrical impedance of both hands with single signal frequency 50KHz, and therefore the index that obtains is single, can only provide body fat rate and lean body mass.With the method for the invention and young, middle aged, the old fat value of the used detection method test of Japanese Omron body fat measuring appliance (HBF-301), and their test result is carried out t respectively by the men and women check, find three groups of lads, Youth Women, middle-aged woman, two kinds of testing result there was no significant differences that detection method obtains; To middle aged man, old man, three groups of old woman, the testing result that two kinds of detection methods obtain has significant difference.Analyze reason, the first since the Fat Distribution of human body mostly at middle lower abdomen, the body fat amount that bimanual bioelectric impedance value calculates whole body is certainly will error bigger; It two is influences that Japanese detection method is not considered oedema, age, and is single-frequency.
Detection method by the body fat analyser (BFA-100) of Beijing Military Area Command's military medicine Research Institute only detects with single signal frequency 50KHz too, and measurement index is single, can only provide body fat rate and lean body mass.
Computing formula in the employed detection method of the Inbody of the U.S. is not suitable for Chinese, does not draw at Chinese.What especially its standard value, marking system all adopted is external data, and for example standard heights is 176cm, obviously is higher than Chinese average height, does not meet Chinese situation.
Because people's race is different, eating patterns are different, the environment difference of life causes the body composition different, so the detection method that western countries' pick-up unit is adopted should not be tested Chinese.And the method for the invention is according to the characteristic Design of Chinese visible human, and suitable asian population, and considers influences such as age, oedema and woman's menopause, in the corresponding experience computing formula these factors is taken into account, makes testing result more accurate.Simultaneously, we are according to the index that detects, according to Chinese Fat Distribution rule, the scoring of design body component distributing, estimate testee's body component distributing with the different weights of testee's body fat number percent and muscle ratios, mark is high more, and then the muscle content ratio is high more in testee's body, and it is reasonable that the body component distributing is tending towards more.
