[Prior art]
Japanese Patent Application Laid-Open No. H10-127608 discloses a method for easily evaluating a physical condition. This measures the user's load on the load measurement unit and the state of sway of the center of gravity, and calculates the area of sway of the center of gravity.

BEST MODE FOR CARRYING OUT THE INVENTION
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an example of an embodiment. FIG. 1 shows an outline of a physical condition evaluation apparatus according to the present invention. In the figure, reference numeral 1 denotes a physical condition evaluation means constituted by a computer. The means 1 includes a measuring means 2 capable of measuring the sway of the center of gravity when the user is on, an input unit 3 for inputting physiological information of the user, subjective evaluation of the user, and the like, and a physical condition evaluating means. Display means 4 for displaying the evaluation value derived by 1 to the user is connected. The physical condition evaluation means 1 is provided with an individual physical condition database containing individual physical condition data of a large number of users. The input unit 3 includes a device such as a keyboard which is input by a user or an operator, as well as a device which takes in necessary data from another database for some data, for example, physiological data.
[0009]
Further, the physical condition evaluation means 1 is connected to the supervisor terminal 5 via a network, and the personal physical database in the physical condition evaluation means 1 and the physical condition evaluation value relating to the user who is currently measuring are referenced from the supervisor terminal 5. You can do it.
[0010]
The upper-level measuring means 2 measures the center of gravity sway as described above. At the time of this measurement, in addition to the center of gravity sway area per predetermined time, the total locus length, the effective value area, the center of gravity moving speed, the center of gravity sway locus, Indices such as frequency characteristics are also output. Note that the measuring means 2 itself may only sequentially output the position of the center of gravity for the sway of the center of gravity, and the above-mentioned respective indexes may be obtained by calculation on the physical condition evaluating means 1 side based on the output of the measuring means 2.
[0011]
Then, the physical condition evaluation means 1 calculates the physical condition using the plurality of indices relating to the above-mentioned center of gravity sway. For example, the physical condition is obtained by physical condition = center of gravity sway area + total trajectory length + effective value area + center of gravity moving speed. The leverage physical condition evaluation value is displayed on the display means 4.
[0012]
At this time, the physical condition = the center of gravity sway area + total trajectory length + the effective value area + the center of gravity moving speed + biological rhythm phase + subjectivity with reference to physiological information and subjective evaluation (subjective activity in this case) obtained through the input unit 3. The physical condition may be determined based on the target activity, and the physical condition evaluation value may be displayed on the display unit 4.
[0013]
Then, the physical condition evaluation means 1 calculates the current physical condition evaluation value x obtained by the above calculation using the average value M and the standard deviation SD of the physical condition evaluation values of the individual physical condition database up to that point, and the physical condition points in the individual = 50 + 10 * (x- M) / SD
Is standardized, and the standardized value is displayed on the display unit 4. From the viewpoint of the user, it is easy to recognize whether the physical condition of today is normal or not.
[0014]
In addition, the supervisor terminal 5, based on the balance function, physiological information, and subjective evaluation of each user, points to note in work on that day, such as “prohibition of work at height”, “prohibition of work outdoors”, “rest It is preferable to make a display such as "make frequent". Further, when there are a plurality of users, it is preferable that a display capable of comparing and examining the physical condition evaluation values of these users can be provided.
[0015]
In the above example, the physical condition evaluation is performed using the center of gravity sway area, the total trajectory length, the effective value area, and the center of gravity moving speed among a plurality of indices relating to the center of gravity sway. Needless to say, the physical condition evaluation may be performed, and further, the physical condition evaluation may be performed using only any two of the above five indices. However, it is preferable to include at least the center of gravity sway area.
[0016]
【The invention's effect】
As described above, in the present invention, the center of gravity sway measuring means and a plurality of frequency characteristics such as the center of gravity sway area, the total trajectory length, the effective value area, the center of gravity moving speed, and the frequency characteristic of the center of gravity sway trajectory relating to the balance function obtained from the center of gravity sway measuring means. The physical condition evaluation means for evaluating the physical condition using two or more of the indices, and a display means for displaying the physical condition evaluation value, the physical condition evaluation using only the center of gravity sway area It is possible to perform a more accurate physical condition evaluation than in the case of performing the evaluation.
[0017]
In addition, an input means for inputting physiological information and subjective evaluation is provided, and the physical condition evaluating means further evaluates the physical condition by evaluating the physical condition by adding physiological information and subjective evaluation to a plurality of indices relating to the balance function. Can be improved.
[0018]
In addition, a physical condition database containing the history of the user's physical condition is provided, and if the physical condition evaluation means is displayed on the display means based on comparison with the previous physical condition evaluation value, the current condition for the user is provided. It becomes easier to understand what the physical condition evaluation value is like.
