Description

Human body rotation measuring instrument

The present invention relates to an assay article, and more particularly to a human body rotation measuring instrument for measuring the softness of rotation of a body.

Softness, like muscle strength and muscular endurance, is an important item of physical fitness. Soft exercise can relieve menstrual pain, general neuromuscular tension and lower back pain. Excellent softness is one of the main factors for athletes' performance and avoiding sports injuries.

Referring to FIG. 1 , a body rotation measuring instrument 1 for measuring the softness of the body rotation is taken as an example, and mainly includes a pair of standing frames 11 , a rail seat 12 mounted on the opposite frame 11 and marked with a scale, and sliding on the rail seat A slider 13 of 12. Before the measurement, a reference line L located at the center of the pair of stands 11 must be drawn on the ground for the alignment of the toes of the feet. The measurement steps of the body rotation measuring instrument 1 are as follows:

Step 1: Do an appropriate amount of warm-up exercise before the test.

Step 2: The athlete's feet stand straight and are slightly separated, and the toes touch the ground reference line L.

Step 3: Rotate the torso, straighten the arm (always maintain in the horizontal plane) and touch the slider 13 backwards, then slowly slide the slider 13 from one end of the rail seat 12 to the other end as far as possible, and stay in the last position. Two seconds. It is worth mentioning that when the slider 13 is touched, it must be performed by means of a fist, and the feet cannot be moved.

Step 4: Record the sliding distance of the slider 13 and compare it with a control. Table, the percent rating of softness is obtained. The greater the percentage level, the higher the softness.

It is worth mentioning that the above reference table can refer to the theory and practice of physical fitness and whole body health (original: Werner WK Hoeger, Sharon A. Hoeger), Chapter 8 Muscle Softness, Table 8.2 Table 8.2 Whole Body Rotation The percentage level of the test results.

However, the drawing of the reference line L and the determination of the sliding distance are all achieved by manual visual observation. It is not only easy to have errors, but also after the measurement, it is necessary to check the table to obtain the percentage of softness, and it is impossible to obtain immediately. Knowing the results, there are inconveniences in use, and lack of compliance with the needs of use.

When the human body is twisted, the feet are easily displaced by the rotation of the body. Therefore, the measurement data may be inaccurate, and the percentage of the softness obtained may be inaccurate.

Accordingly, it is an object of the present invention to provide a human body rotation measuring instrument which can improve the convenience and utility of measurement.

Thus, the human body whole body rotation measuring instrument of the present invention comprises a calibration unit, a measuring unit, and an electronic control unit. The calibration unit has a bottom plate for standing on the feet, and at least one reference surface formed on a top surface of the bottom plate and flush with the toes of the feet along an X-axis direction parallel to a top surface of the bottom plate, formed on the bottom plate a top spacer and a middle spacer extending parallel to a top surface of the bottom plate and perpendicular to the X-axis, and a second sliding plate spanning the middle partition and sliding along the X-axis direction to the bottom plate The intermediate partition and the sliding plate respectively sandwich an inner side and an outer side of the two legs. The measuring unit has a mounting on the bottom plate a rail seat extending upward and along a Y-axis direction, and a slider sliding to the rail seat in a direction of twisting of the body. The electronic control unit has a measuring device for measuring the sliding distance of the slider, a central control module for receiving the aforementioned measurement result and calculating a percentage of the body rotation softness degree, and is electrically connected to the central control module and used for A carrier that displays relevant information.

The effect of the invention is that the electronic design can be utilized, and the result is known immediately after the measurement, thereby improving the convenience and practicability in the measurement.
