1. test purpose
Test students' height, cooperate with weight test, evaluate students' body symmetry, and evaluate students' growth and development level and nutritional status.
2. Field equipment
Height measuring instrument. Before use, check 0: 00, and use a steel ruler to measure whether the height from the plane of the datum plate to the red scribe line in front of the column is 10.0 cm, and the error shall not be greater than 0. 1 cm. At the same time, check whether the column is vertical, whether the joint is tight, whether there is shaking, whether the parts are loose, etc. And correct it in time.
3. Detection method
Subjects stand barefoot on the altimeter floor (upper limbs naturally droop, heels together, toes separated by 60 degrees). The heel, sacrum and two scapular regions are in contact with the column, and the trunk is naturally straight, the head is straight, and the upper edge of tragus and the lower edge of orbit are horizontal (Figure 3- 1). The tester stands on the right side of the subject, gently slides the horizontal pressure plate along the column and gently presses it on the top of the subject's head. When the tester reads, his eyes should be at the same height as the horizontal plane of the platen, and the recorder will repeat and record. In centimeters, accurate to one decimal place. The test error shall not exceed 0.5 cm.
4. Preventive measures
(1) The altimeter should be laid flat against the wall, and the scale of the column should face the light source.
(2) Strictly master the measurement posture requirements of "three-point alignment with column" and "two-point levelness". When the tester reads, his eyes must be at the same height as the pressure plate. When his eyes are higher than the platen, he should squat down, and when he is lower than the platen, he should raise his eyes.
(3) When the horizontal pressure plate is in contact with the head, the tightness should be moderate, those with fluffy hair should be pressed tightly, the braids and knots on the top of the head should be loosened, and the hair accessories should be removed.
(4) After reading, immediately push the horizontal clip to a safe height to prevent damage.
(5) Before measuring the height, the subjects should avoid strenuous physical activity and physical labor.
Second, weight.
1. test purpose
Test students' weight, cooperate with height test, evaluate students' body symmetry, and evaluate students' growth and development level and nutritional status.
2. Field equipment
Lever scale or electronic scale. Check its accuracy and sensitivity before use. The required precision error is not more than 0.65438 0%, that is, the error per 100 kg is less than 0.65438 0 kg. Inspection method: Weigh 10 kg, 20 kg and 30 kg standby standard weights (or replace them with equal-weight calibration weights) respectively, and check whether the error between index reading and standard weights is within the allowable range. The test method of sensitivity is: put a weight of 100g and observe the change of scale. If the ruler is raised by 3mm or the cursor is moved away by 0. 1kg, and the ruler remains horizontal, the requirements will be met.
3. Detection method
When testing, the lever scale should be placed on a flat ground, and the 0 o'clock should be adjusted to the level of the scale. The subjects were barefoot and the male subjects were wearing shorts. Female subjects wear shorts and short-sleeved shirts and stand in the center of the scale (Figure 3-2). The tester places appropriate weights and moves the cursor until the balance is balanced. The reading is in kilograms, accurate to one decimal place. The recorder will record the reading after repeating it. The test error shall not exceed 0. 1 kg.
4. Preventive measures
(1) Subjects shall not engage in strenuous physical activity or physical labor before weighing.
(2) The subject stands in the center of the scale, and the upper and lower lever scales should be moved lightly.
(3) Every time the lever scale is used, it must be calibrated. Testers should check the weight before each reading to avoid mistakes.

3. Detection method
Boys in junior high school, senior high school and university use 40 cm high steps (or stools), while girls in junior high school, senior high school and university and boys and girls in grade 5 and 6 of primary school use 35 cm high steps (or stools) to exercise on the treadmill. Before the test, the pulse at rest was measured, and then the subjects did mild preparatory activities, mainly moving the joints of lower limbs. The frequency of going up and down the steps (or stools) is 30 times/minute, so the rhythm of the metronome is 120 times/minute (moving up and down four times each time). Subjects completed the experiment according to the rhythm of metronome.
The testee starts from the preparation posture, (1) the testee puts one foot on the steps; (2) The legs of the treadmill stand upright on the platform; (3) First set foot on the platform and descend to the ground; (4) Return to the preparation posture. Do it continuously for 3 minutes at a speed of 2 seconds (according to the rhythm of the metronome) (Figure 3-3). Keep still and rest after exercise, and measure the pulse number from 1 minute to 1 minute and a half, from 2 minutes to 2 minutes and a half, and from 3 minutes to 3 minutes and a half after exercise. The evaluation index is obtained by the following formula. If the calculation result contains decimals, the 1 digit after the decimal point shall be rounded to round off the score.
Evaluation index = duration of up-and-down movement on the treadmill (seconds) × 100/2× (sum of three pulse measurements)
4. Preventive measures
(1) Students with heart disease cannot take the exam.
(2) According to the rhythm of 2 seconds, next time. When the subjects can't keep up with the rhythm, they should be reminded in time. If they can't keep up with the rhythm three times in a row, they should stop the test to avoid injury accidents.
(3) When going up and down the steps, keep your knees and hips straight.
(4) Candidates are not allowed to take their own pulse.
(5) If the subject can't complete the load exercise for 3 minutes, it shall be calculated according to the actual duration of the steps and the steps, and the calculation formula is the same as above.
Fourth, vital capacity.
1. test purpose

Put the spirometer main unit on a stable desktop, and check whether the power cord and interface are firm. Press the work key, and "0" will be displayed on the LCD screen, indicating that the machine has entered the working state. It is best to preheat for 5 minutes before testing.
First, tell the subjects not to be nervous and try to blow with moderate speed and strength. Let the subjects stand in front of the instrument and hold the blowing nozzle, and stand in front of the spirometer and try to blow 1 2 times. First, check whether the instrument reacts, and try whether there is air leakage in the mouth or nose, adjust the mouth and mouth and use the nose clip (or pinch the nose yourself); Learn to breathe deeply (avoid shrugging your shoulders and lifting your breath, but breathe slowly like you smell fancy). After taking a deep breath once or twice than usual, the subjects should take a deep breath, hold their breath, and slowly exhale into the mouth until they can no longer breathe, so as to prevent inhaling from the mouth at this time, and should not inhale twice during the test. After blowing, the last number displayed on the LCD screen is the milliliter value of vital capacity. Each subject measured three times, with an interval of 15 seconds, and recorded three times, and the maximum value was taken as the test result. In milliliters, no decimals are reserved.
4. Preventive measures
(1) The smoothness and dryness of the measuring part of the electronic spirometer are the key to the accuracy of the instrument, and the duct of the blowing cylinder must be above to avoid saliva or debris blocking the airway.
