目的：根据最大耗氧量(MaxO2)和最大肌肉自主收缩量(MVC)对运动项目进行分类，采集不同类型运动员的桡动脉脉搏波，分析其脉搏波波形及参数。方法：使用ADInstrument公司的PowerLab数据采集系统及配套软件LabChart采集304名受试者脉搏波，对所测脉搏波进行调整，使波形周期和幅度分布在0～100的范围内，分析最大值相对时间Tm，重搏波谷横纵坐标X、Y，脉搏波波形面积波形参数K值以及脉搏波年龄指数(SDPTG age index)。结果：随着MaxO2升高，MVC-1组与MVC-2组的脉搏波降支曲线逐渐下移，最大值点先右移后左移，重搏波谷点向左下方移动，K和SDPTG逐渐减小；而MVC-3组的降支曲线逐渐上移，最大值点逐渐右移，重搏波谷点向左上方移动，K和SDPTG逐渐增大。随着MVC升高，MaxO2-1组的降支曲线逐渐下移，最大值点逐渐左移，重搏波谷点向左下方移动，K和SDPTG逐渐减小；MaxO2-2组的降支曲线逐渐上移，最大值点逐渐左移，重搏波谷点向左上方移动，K和SDPTG逐渐增大；而MaxO2-3组的降支曲线先下降后抬高，最大值点先左移后右移，重搏波谷点向左侧移动，K和SDPTG先减小后增大。结论：各项运动在MaxO2相同的情况下，MVC各组的脉搏波参数变化趋势有所不同；而在MVC相同的情况下，MaxO2各组的脉搏波参数变化趋势均有不同。脉搏波参数变化可反映人体心血管功能，A类、F类和I类运动的运动员心血管功能相对较好。

Objective:Classify the sports events by the maximal oxygen uptake (MaxO2) and the maximal muscular voluntary contraction (MVC). Collect the radial pulse wave of different sports events and discuss the pulse waveform and characteristic parameters. Methods: Radial pulse waveform on 304 subjects was collected, by using PowerLab and its bundled software LabChart 7, developed by ADInstrument. Normalize each radial pulse waveform and let the waveform cycle and amplitude distribute in the range of 0-100. Analyze the relative time of the maximum point Tm, the abscissa X and ordinate Y of dichotic notch, the pulse waveform area K and the pulse wave age index SDPTG. Results: With increasing MaxO2, the pulse wave descending curve of MVC-1 and MVC-2 group gradually moves down, the maximum point first moves to the right and then left, the dichotic notch point moves to the lower-left corner, K and SDPTG gradually decreasing;And the pulse wave descending curve of MVC-3 group gradually moves up, the maximum point gradually moves to the right, the dichotic notch point moves to the top-left corner, K and SDPTG gradually increasing. With increasing MVC, the pulse wave descending curve of MaxO2-1 group gradually moves down, the maximum point gradually moves to the left, the dichotic notch point moves to the lower-left corner, K and SDPTG gradually decreasing; The pulse wave descending curve of MaxO2-2 group gradually moves up, the maximum point gradually moves to the left, the dichotic notch point moves to the top-left corner, K and SDPTG gradually increasing; And the pulse wave descending curve of MaxO2-3 group first moves down then up, the maximum point first moves to the left and then right, the dicrotic notch point moves to left, K and SDPTG first decreasing then increasing. Conclusion:The pulse wave changing trend of MVC groups are different while the sports have the same MaxO2. And the pulse wave changing trend of MaxO2 groups are as well as different while the sports have the same MVC. Pulse waveform parameters can reflect the cardiovascular function, and the cardiovascular function of athletes in Types A, F and I is relatively well.
