Description

Step test system for test of physical fitness

The present invention relates to a step test system used when performing an individual health fitness evaluation in a place such as a school or a group exercise facility, and more specifically, to adjust the height of the scaffold for various kinds of step tests, The present invention relates to a step test system for evaluating the fitness and the end point, and receiving the heart rate data from the heart rate monitor in real time and automatically performing the fitness assessment.

In general, a cardiopulmonary fitness test is performed to evaluate an individual's health fitness or to exercise according to an individual's health condition. Cardiopulmonary fitness is a measure of the heart's ability to send blood with abundant oxygen to the muscles.Healthy humans can send large amounts of blood to their muscles each time they contract, and they have high levels of cardiopulmonary fitness. Can be. In order to measure the cardiopulmonary ability of the heart, the oxygen intake should be measured directly, which requires a lot of time for the technical complexity, the cost and the measurement. Therefore, methods for estimating the maximum oxygen uptake through heart rates measured from standardized submaximal tests have been developed, and step testing is the most widely used standardized maximal exercise.

The most common types of step tests are the Harvard step test, the Queens College test, and the Tecumseh step test. The Harvard step test shows that a man with a height of 50cm and a woman with a height of 40cm is placed in front of an obstacle, and the manager starts or puts one right or left foot on the obstacle. Put your feet back on the floor. If you have four, put your last feet on the floor. Repeat this operation for 5 minutes at a speed of about 30 times for about 1 minute. After the exercise, the average heart rate is measured between 1 minute and 1 minute and 30 seconds, between 2 minutes and 2 minutes and 30 seconds, and between 3 minutes and 3 minutes and 30 seconds, to obtain a physical efficiency index (PEI) as shown in Equation 1 below.

The aptitude level is determined by comparing the result value of Equation 1 with Table 1 below.

Aptitude level man Woman Very good 96 or more over 90 Great 82-95 80-95 usually 68-81 68-79 Weakness 54-67 55-67 Very weak 54 or less 55 or less

The Queen's University Step Test takes four steps, the same as the Harvard Step Test, in front of an obstacle about 43.18 cm in height for men and 40.64 cm in height. Calculate the maximum oxygen intake (V02max) by calculating the average heart rate for 10 seconds between 5 and 15 seconds during recovery.

     The Tecumsche step test repeats four steps for three minutes at a speed of 24 times per minute in front of an obstacle with a height of 20.3 cm, and measures the heart rate for 30 seconds in a standing posture after the end of the exercise. To determine the level of physical fitness.

The physical fitness index, the maximum oxygen intake, and the physical fitness level measured by the above three methods are used to evaluate the individual's health fitness and calculate the exercise load intensity accordingly.

However, in order to perform the step test, the heights of the obstacles are different depending on the gender such as the male and female, and the type of the step test, and the number of steps per minute is different. There are no obstacles, and the number of steps performed per minute is not accurately measured by the fact that one manager uses a clock or a metronome to signal as a whistle or a command. In addition, the heart rate is also measured by counting the heart rate per minute by looking at the watch by evolving the wrist or neck area is not accurate heart rate calculation. In addition, there is a possibility of error and error by manually evaluating health fitness by looking at the heart rate calculated by the individual and the above equation and table.

Therefore, the present invention has been proposed to solve the problems of the prior art as described above, the object of the present invention is to automatically adjust the height of the footrest when the user selects only gender and step test type, press the start switch As a result, guide sounds such as preparation, one, two, three, four, and the end of the test are output according to the step speed of the automatically selected step test, so that accurate health fitness evaluation can be made.

Another object of the present invention is to measure the heart rate from a certain time after the end of the exercise load test as described above, if the end of the exercise load test step test device is a wireless heart rate monitor or the user wearing the test end signal The heart rate monitor is signaled to the heart rate monitor connected to the step test device by wire, and the measured heart rate data is compared with the formulas and table values for the evaluation of the health fitness in the control unit of the step test device to make an accurate health fitness evaluation. These data are transmitted to a laptop, computer or PDA at a short distance by using a wireless communication method to be stored, analyzed and managed for each user.
