Abstract

Disclosed is an apparatus for assuming the information on the amount accumulated visceral fat in a human body with a high degree of accuracy. It comprises: at least a unit for collecting pieces of information on the identification of the human body and a unit for collecting pieces of information on breathing function, thereby making the visceral fat accumulation calculating unit provide the information on the amount accumulated visceral fat based on the so collected pieces of information.

Claims

a body identifying unit;

a breathing function determining unit;

a computing unit,

wherein said body identifying unit obtains information on the identification of the human body;

said breathing function determining unit obtains information on the breathing function; and

said computing unit calculates information on the amount accumulated visceral fat on the basis of the so obtained pieces of information on the identification of the human body and the breathing function.

2. An apparatus for assuming information on the amount accumulated visceral fat of a human body according to claim 1 wherein the breathing function determining unit comprises a breathing amount determining unit which determines the breathing amount both at the time of maximum inspiration and at the time of expiration, and a vital capacity computing unit which calculates pieces of information on the breathing function on the basis of the amounts of the maximum inspiration and maximum expiration thus determined.

3. An apparatus for assuming information on the amount accumulated visceral fat of a human body according to claim 1 wherein the breathing function determining unit comprises a trunk bioimpedance variation determining unit which determines the variation between the trunk bioimpedance at the time of maximum inspiration and that at the time of maximum expiration, and a vital capacity computing unit which calculates information on the breathing function on the basis of the so determined trunk bioimpedance variation between the maximum inspiration and maximum expiration.

4. An apparatus for assuming information on the amount accumulated visceral fat of a human body according to claim 1 wherein it further comprises a body composition determining unit which obtains information on the body composition of the human body, thus permitting said computing unit to calculate information on the amount accumulated visceral fat on the basis of, among others, the so obtained pieces of information on the body composition of the human body.

5. An apparatus for assuming information on the amount accumulated visceral fat of a human body according to claim 2 wherein it further comprises a body composition determining unit which obtains information on the body composition of the human body, thus permitting said computing unit to calculate information on the amount accumulated visceral fat on the basis of, among others, the so obtained pieces of information on the body composition of the human body.

6. An apparatus for assuming information on the amount accumulated visceral fat of a human body according to claim 3 wherein it further comprises a body composition determining unit which obtains information on the body composition of the human body, thus permitting said computing unit to calculate information on the amount accumulated visceral fat on the basis of, among others, the so obtained pieces of information on the body composition of the human body.

7. An apparatus for assuming information on the amount accumulated visceral fat of a human body according to claim 4 wherein said body composition determining unit comprises a hand-to-hand bioimpedance determining unit which determines the bioimpedance appearing between both hands, and a body composition calculating unit which calculates information on the body composition of the human body on the basis of the so determined hand-to-hand impedance.

8. An apparatus for assuming information on the amount accumulated visceral fat of a human body according to claim 5 wherein said body composition determining unit comprises a hand-to-hand bioimpedance determining unit which determines the bioimpedance appearing between both hands, and a body composition calculating unit which calculates information on the body composition of the human body on the basis of the so determined hand-to-hand impedance.

9. An apparatus for assuming information on the amount accumulated visceral fat of a human body according to claim 6 wherein said body composition determining unit comprises a hand-to-hand bioimpedance determining unit which determines the bioimpedance appearing between both hands, and a body composition calculating unit which calculates information on the body composition of the human body on the basis of the so determined hand-to-hand impedance.

10.
