Description

20-meter switchback tester and testing facilities including the same

technical field

The utility model relates to a 20-meter turn-back running tester and a 20-meter turn-back run test facility, which are particularly suitable for the field of national fitness.

Background technique

Aerobic endurance is a standard for assessing body circulation and respiratory system function. Good aerobic endurance can reduce the degree of hypoxia during people's activities, improve the utilization rate of oxygen during exercise, and accelerate fatigue recovery. Having good aerobic working ability can effectively prevent the occurrence of various acute and chronic diseases and reduce the risk of illness. Aerobic endurance reflects the individual's cardiopulmonary function, muscle type, blood carrying and transporting oxygen ability and tissue absorbing and utilizing oxygen ability. It can comprehensively and objectively reflect the individual's physical condition. The current simple evaluation methods include: 800-meter run, step test and 20-meter switchback run.

The 800-meter run is generally completed in about 3-4 minutes, and it is mainly powered by anaerobic glycolysis, which cannot evaluate students' aerobic endurance well. During the step test, the subject may not exercise under the same load due to subjective factors (such as: slow frequency, inappropriate movements), which directly reduces the scientific validity of the test results and leads to deviations in the evaluation results. The 20-meter turn-back run stimulates the central nervous system with different rhythms, so that the subjects can try their best to complete the test task of the 20-meter turn-back run with increasing load, and more accurate evaluation results can be obtained. Previous experiments have also confirmed that the 20-meter switchback run is a good means to indirectly evaluate the level of aerobic endurance.

Most of the existing 20-meter switchback test equipment is self-assembled by the testers, which lacks professionalism and integration. During the implementation process, more manual recording is used to obtain test data. At the same time, the test is easily affected by the environment, and the operation is relatively complicated. The results Not intuitive enough.

Detailed ways

Referring to Fig. 1, a kind of 20 meters switchback running tester, comprises processor and the display module 1 that is connected with described processor, input module 2, memory and sound player 5.

The memory is pre-stored with standard formulas, operating programs, test music, prompt sounds, etc., and the standard formulas are divided into male and female formulas.

Preferably, the 20-meter turn-back running tester also includes a sensing device 3 for sensing the number of laps and time of the tester, the sensing device 3 is connected to the processor, and the sensing device 3 can be a proximity sensor or the count button. When the sensing device 3 is a proximity sensor, the proximity sensor will automatically send a signal to the processor every time the tester passes the sensing position of the proximity sensor during the test, and the processor will record and store the relevant information in the memory. In the case where the induction device 3 is a counting button, during the test, the tester presses the counting button every time the tester passes through the 20-meter turn-back running tester once, and the counting button will send a signal to the processor. A signal is recorded by the processor and the relevant information is stored in the memory.

Preferably, the tester also includes a housing 6, and the display module 1, the input module 2, the sound playing device 5 and the sensing device 3 are installed in the housing 6, wherein the display terminal, the input terminal of the display module The input terminal of the module, the sound player of the sound playing device and the sensing end of the sensing device are exposed outside the housing, and the processor and memory are arranged in the housing 6 . Portable for testers.

Referring to Fig. 2, a kind of 20-meter turn-back running test facility comprises runway 7 and 20-meter turn-back run tester 8, it is characterized in that described 20-meter turn-back run tester 8 is arranged on described runway 7, on described runway 7 A marker 9 is set at a position 20 meters away from the 20-meter turn-back running tester, and the 20-meter turn-back run tester includes a processor and a display module connected to the processor, an input module, a memory and a sound playback device. It is convenient for testers to run back and forth between the 20-meter turn-back running tester and the marker.
