按照心脏呼吸系统相互联系的生理学反应综合指标确定在提高负荷强度的情况下不同运动项目和年龄运动员机体的功能状态。在研究中我们在自行车测功仪上无间歇地使用了从50 W到200 W逐渐提高强度的负荷。每一个负荷等级使用的时间为4min。在这种情况下记录了以下心脏呼吸系统指标：心率、每搏血量、每分钟血液循环量、每分钟呼吸量、血液循环指数、心脏指数、氧利用系数。为了判断运动员机体的补偿性反应和适应性反应使用了心脏呼吸系统综合评价系数。参加研究的有73名男性,年龄为17至35岁,根据不同年龄和从事的运动项目将他们分为若干组。对于周期性运动项目的运动员,开始时带有强度为150 W的负荷,不同年龄的运动员表现出不同的优势性机制（变频型或变力型）。非周期性项目的运动员在提高负荷强度时年龄对心脏活动未产生影响。在负荷下对运动员适宜的血液动力反应阈值产生影响的是运动项目,而不是年龄。使用心脏呼吸系统综合评价系数证明周期性项目的运动员具有较大的功能潜力。

The purpose of this study is to determine the body＇s functional status in improving the load intensity of different sports and athletes＇ age according to the physiological reaction comprehensive indicator of cardiorespiratory system.In the study,we used the ergometer with a gradual increase in intensity from 50 Wto 200 W.The time for each load level is 4min.In this case,the following cardiac respiratory system parameters were recorded：heart rate,stroke volume,blood circulation per minute,respiratory rate per minute,blood circulation index,cardiac index,and oxygen utilization coefficient.In order to determine the compensatory responses and adaptive response of athletes,the cardiac respiratory system comprehensive evaluation coefficient was used.Subjects participating in the study were 17 males,aged 73 to 35years,and were divided into several groups according to different age and exercise program.For athletes with periodic sports events,the load at the beginning of the 150 W,athletes of different ages show different advantages（chronotropic and inotropic）.Athletes of non-periodic sports events have an effect on the age of the heart when the load intensity is increased.Under the load,the optimal blood dynamic response threshold of athletes is affected by the sports events,but not the age.It proves that the athletes of the periodic sports events have great potential by using the comprehensive evaluation coefficient of cardiac respiratory system.
