After participating in oxygen metabolism, the functional level of vascular system is improved, which is manifested by the increase of step test index after completing step test and the decrease of pulse rate after quantitative load test.
Oxygen metabolism means that the transport of oxygen demand and oxygen intake reaches a balanced state. In the process of oxygen transportation, the accumulation rate of lactic acid produced by the rest of the body remains stable and the transportation is safe. High fat intake is beneficial to improve the function of vascular system.
Step test: Men use a step (or stool) with a height of 40 cm and a step (or stool) with a height of 35 cm to measure the quiet pulse before the treadmill running test. The subjects made simple preparations. The frequency of main limb joint step (or stool) is 30/ metronome rhythm is 120/
The subjects completed the experiment according to the metronome rhythm, and the tester prepared the posture in four steps.
Step 1: Testers step on the steps.
Step 2: Stand on the platform with your legs straight.
The third step is to set foot on the platform first.
The fourth step is the original preparation posture.
Do it continuously for 3 minutes at the speed of 2 seconds (according to the metronome rhythm), and immediately sit in the chair to measure the pulse number at the end of the operation 1 to 1 half minute, 2 to 2 and a half minutes, and 3 to 3 and a half minutes, and find the evaluation index by column. Calculate the number of points in the node containing 1, and round them to the whole number for evaluation.
Evaluation index = [treadmill running duration (seconds) * 100]/[2 * (3 pulse measurements)]
The standard step test of male test items is 67 excellent, 53-65 good, 46-52 pass and 45 pass.
The standard step test evaluation of each test item is 60 excellent, 49-59 good, 42-48 pass, and 4 1 pass.
