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 assessment method for accurate selection of athletes. The method includes the following steps: 1) testing a per stroke volume SV1 and a heart rate HR1 of a tested athlete at rest, and calculating cardiac output per minute CO1 at rest according to CO being SV*HR; 2) performing a quantitative load cardiovascular exercise test on the athlete, and measuring an average anaerobic power PP; 3) immediately testing the athlete after completing the exercise in step 2), measuring a per stroke volume SV2 and a heart rate HR2 immediately after exercise, and calculating the calculating cardiac output per minute CO2 immediately after exercise; 4) calculating a cardiac index CI1 at rest and a post-exercise immediate cardiac index CI2 according to the cardiac index CI being cardiac output per minute CO / body surface area BSA; and 5) calculating a cardiac reserve index CRI: CRI being K*PP / (CI2-CI1), wherein the CRI value is positively correlated with the cardiacreserve capacity, and accordingly, making a more accurate quantitative assessment of the cardiac function level of the tested athletes.

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 ...
