Embodiment Construction

[0065] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0066] Such as Figure 1~2 As shown, the cardiac function evaluation method for athletes' accurate material selection provided by the present invention comprises the following steps:

[0067] 1) Test of stroke per stroke and cardiac output per minute at rest

[0068] Measure the stroke volume SV of the athletes under test at rest 1 and heart rate HR 1 , according to the formula: cardiac output per minute CO = stroke output per stroke SV × heart rate HR, calculate the cardiac output per minute CO at rest 1 .

[0069] The measurement methods of cardiac output have transitioned from invasive measurement of FICK, indicator dilution method, temperature dilution method (TD) to today's non-invasive measurement of bioimpedance method, Doppler ultrasound method (DECO), among which DECO is relatively simple and easy to operate. , and a lar...

Abstract

The invention discloses a cardiac function evaluation method for athletes' accurate selection of materials, which comprises the following steps: 1) testing the stroke output volume SV of the athletes under test when they are at rest 1 and heart rate HR 1 , according to CO=SV×HR, calculate the resting cardiac output per minute CO 1 2) The tested athlete carries out the quantitative load cardiovascular function exercise experiment set, and the average anaerobic work PP is measured; 3) The tested athlete is tested immediately after completing the exercise in step 2), and the daily PP immediately after the exercise is measured. Gaussian output SV 2 and heart rate HR 2 , to calculate the CO per minute immediately after exercise 2 ; 4) Calculate the heart index CI at rest according to the heart index CI=per minute cardiac output CO / body surface area BSA 1 and CI 2 ; 5) Calculating the Cardiac Reserve Index CRI: CRI=K*PP / (CI 2 ‑CI 1 ), the CRI value is positively correlated with the cardiac reserve capacity, and based on this, a more accurate quantitative evaluation of the cardiac function level of the tested athletes can be made.

Description

technical field [0001] The invention relates to the field of athlete selection, in particular to a cardiac function evaluation method for accurate selection of athletes. Background technique [0002] The quality of the cardiovascular system directly affects the athlete's ability to bear exercise load. Accurate evaluation of the cardiovascular system function is the most basic requirement for identifying excellent athletes in the selection of athletes. At present, there are many indexes for evaluating the cardiovascular function of athletes, and the most commonly used indexes of cardiac function evaluation mainly include step index, simple cardiac function index of 30 squats, etc. These indicators have the advantages of simple operation and convenient calculation, and have made contributions to the evaluation of athletes' cardiac function in a certain period of time. [0003] Cardiac reserve is one of the most important and sensitive indicators to reflect the heart function ...
