基于心音信号的柔道运动员心脏储备功能无创性检查与评估

Non Invasive Examination and Evaluation of Cardiac Reserve Function of Judo Players Based on Heart Sound Signal

为了研究男子竞技柔道运动员心脏储备功能,分析不同水平男子柔道运动员心脏储备功能的差异及特征,为科学评价男子柔道运动员竞技水平及训练效果提供评价方法。研究采用定量负荷测试方案和GXT测试方案,运用运动心力检测仪和CONTEC型心电工作站对25名不同水平男子柔道运动员进行心脏储备功能测试。研究结果表明:等级越低的运动员,心脏储备功能动员越大,高水平柔道运动员具有较大的心脏储备空间;等级越高的柔道运动员,最大心率维持的时间越长,心脏储备功能水平越强。研究中表明CRI1A、CRI2A、CRI3A、THRmax指标具有显著代表性,可作为评价评定柔道运动员心脏储备功能的灵敏指标。

In order to study the cardiac reserve function of men＇s competitive athletes Judo, difference analysis of cardiac reserve function of male athletes of different levels and characteristics of Judo, provide evaluation method for scientific evaluation Judo men＇s athletic level and training effect. In this study, the quantitative load test and the GXT test program were used to test the cardiac reserve function of 25 different levels of Male Judo Athletes by using the exercise heart rate detector and CONTEC ECG workstation. The results showed that the lower the level of the athletes, the greater the cardiac reserve function of mobilization, high level athletes Judo has greater cardiac reserve space; the higher the level of the Judo athletes, the maximum heart rate maintain longer, stronger level of cardiac reserve function. The results showed that CRI1A, CRI2A, CRI3A and THRmax were significant, and could be used as a sensitive index to evaluate the cardiac reserve function of judo athletes.
