Jumping type anaerobic athletic ability tester

Abstract

A jumping type anaerobic athletic ability tester comprises a steel frame, a supporting rod welded to the inner side of the steel frame in an erected mode and a substrate shell arranged on the surfaceof the supporting rod in a sleeving mode. A substrate is fixedly connected to the interior of the substrate shell through screws, a main control CPU is embedded in the middle of the substrate, and a gyroscope, a stay wire encoder, a voltage conversion interface, Bluetooth and a communication interface are sequentially arranged in the area, located on the periphery of the main control CPU, of the upper surface of the substrate. The technical key points are as follows: compared with the existing continuous jump test system, the accuracy is high, the jump height can be accurately measured, and the jump process is divided into two stages of work doing for measurement; the jump height can be measured in a segmented manner and the lower limb work can be calculated separately, so that the error problem of the final lower limb anaerobic movement evaluation result (such as the average power, the maximum power, the minimum power, the total work, the maximum power per kilogram of weight, the minimum power per kilogram of weight and the power failure index) is solved and reduced.

Description

technical field [0001] The invention belongs to the technical field, in particular to a jumping type anaerobic exercise capacity tester. Background technique [0002] In the past, the continuous jumping test system measured the flight time of the tester. According to the free fall formula h=1 / 2gt2, after directly measuring the flight time, the jump height was indirectly calculated. Then the tester will perform various movements in the air when the tester is in the air. The heights measured in the two states of keeping the lower limbs always straight or bent are completely different, so there will be a high error, and the strength of the lower limbs cannot be accurately tested. There will be a certain gap between the work done and the real level of the tester. [0003] At the same time, the power bicycle (WinGate Netherlands) is currently used in the continuous jump test of the tester. This bicycle is a cycle force measuring instrument. Although it can accurately measure and...

Problems solved by technology

Then the tester will perform various movements in the air when the tester is in the air. The heights measured in the two states of keeping the lower limbs always straight or bent are completely different, so there will be a high error, and the strength of the lower limbs cannot be accurately tested. There will be a certain gap between the work done and the real level of the tester

[0003] At the same time, the power bicycle (WinGate Netherlands) is currently used in the continuous jump test of the tester. This bicycle is a cycle force measuring instrument. Although it can accurately measure and evaluate the anaerobic exercise capacity of the lower limbs, it cannot directly and accurately measure the jumping of the lower limbs. The advantages and disadvantages of sexual power; at the same time, the power bicycle (WinGate Netherlands) needs to be connected to the computer, and the data needs to be extracted from the computer. The degree of intelligence is average, and the extraction of data takes a lot of time
