Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to bioelectrical impedance analysis (BIA).
The present invention relates to a weight scale having a function of analyzing body fat by using a method and a function of measuring a posture balance of a body with a load sensor.

[0002]

2. Description of the Related Art The bioelectrical impedance method is based on the principle that an electric current flows through a muscle containing water, and a weak alternating current is applied to the human body to measure the electrical resistance or electrical conductivity of the human body to determine the height and weight. This is a method of measuring and calculating the body water content and body fat content from it. A conventional scale for analyzing body fat using the bioelectrical impedance method is shown in FIG.
As shown in (a) and FIG. 8 (b), a support base 5 for supporting the entire equipment, a load sensor 4 installed on the support base 5,
The load sensor 4 and the stepping plate 3 are installed on the load sensor 4. Two electrodes 1 and 2 with which the backs of both feet contact each other are installed on the step 3, and the subject can measure the weight and impedance by riding on the step 3.

Posture balance in physical activity is the ability to control movement by receiving muscular strength, bioinverse information and neurological sensory information. This posture balance is an ability that is essential for people to maintain a stable posture, exert their maximum ability during sports activities, and prevent injuries when sending daily routines. Is the basic information for determining incorrect posture, abnormal nervous system, imbalance in physical development, etc. Such a physical posture balance test is utilized in the field of sports medicine and rejuvenation medicine in the field of sports medicine and rejuvenation medicine for the examination and rejuvenation training of injured athletes and patients. The conventional device for measuring the posture balance employs a method in which the load sensors 4 are normally installed on the lower sides of both feet as shown in FIG. 9 and the load applied to both feet for a certain period of time is measured.

The above-mentioned body fat measurement and posture balance test are both highly basic and practical in terms of clinical aspects. In addition, the two tests are closely related to each other, and the body composition of each part is closely related to the posture balance. Therefore, it is more clinically useful to perform both tests at the same time so that the results can be cross-referenced. However, it is cumbersome and time-consuming to separately carry out the above-mentioned tests by separately using a conventional scale having a function of measuring body fat and a conventional device for measuring posture balance. Therefore, the inventor of the present patent application has both a function of measuring body fat using the bioelectrical impedance method and a function of measuring body posture balance as one method for solving such a drawback. We have developed a weight scale.
