目的：探讨最大耗氧量（.VO2 max ）与安静时心脏、肺功能的相关性，以及不同.VO2 max水平受试者的心脏和肺功能差异。方法：对66名女大学生（年龄：20±2岁，BMI ：20．88±1．32）志愿者进行.VO2 max（K4b2）、心输出量（NICOM ）和肺功能（VRI）测试。完成测试的受试者根据.VO2 max （ml／kg／min ）等级评价标准分为正常和偏低组。数据分析包括.VO2 max与心输出量和肺功能的 person相关分析和分组后的独立样本 t检验。结果：1）.VO2 max（ml／kg／min）与VE（P＜0．01）和呼吸商显著相关（＜0．05），与肺呼吸振动强度显著相关（P＜0．05），与心输出量无显著性相关（P＞0．05）。2）.VO2 max偏低和正常两组间的身高、体重和BMI均没有显著性差异（P＞0．05）。3）偏低组的通气量显著低于正常组，而呼吸商显著高于正常组（ P＜0．01）。4）2组间的心输出量各指标、肺呼吸振动强度和 QLD均无显著性差异（P＞0．05）。5）.VO2 max偏低组受试者的MET 、QLD和 EVP存在一定的不足。结论：1）研究显示.V O2 max受通气量影响较大，与肺的呼吸强度存在正相关，但与安静时心输出量不相关。2）相比.VO2 max偏低组，正常组的呼吸深度（运动中）显著要高，氧气参与代谢供能的比例和效率可能要好。3）不同.VO2 max水平受试者安静时的心脏功能没有差异，提示.V O2 max偏低组受试者并没有输在“起跑线”上。4）从整体的肺呼吸功能看，.V O2 max偏低组比正常组要差，而这种不足似乎又影响了其在运动中气体参与交换的水平和潜力。

Objective :This paper explores the correlation between .VO2 max and function of rest‐ing heart and lung ,and compare the difference in participants of different .VO2 max level be‐tween .VO2 max and function of heart and lung .Method :Testing 66 female college students’ (age :20 ± 6 ,BMI :20 .88 ± 1 .32 ) .VO2 max ,Cardiac output ,and lung function .Dividing the participants into two groups (normal or less than normal) based on the testing results .Con‐ducting Independent‐Samples T Test on each groups .Results :1) There is a significant correla‐tion between .VO2max(ml/kg/min) with VE (P< 0 .01) ,and the respiration quotient (P<0 .05) and the lungs breathing vibration intensity(P< 0 .05) .There is no significant correla‐tion between .VO2max(ml/kg/min) and the cardiac output ;2)There is no significant differ‐ence between the participants’height ,weight and BMI respectively (P> 0 .05);3)The ventila‐tion volume of the“below‐average” group is significantly lower than the“normal” group while the respiration quotient of the former group is larger than the latter one’ s ( P< 0 .01 );4)There is no significant difference between the two groups’ indexes of Cardiac output ,the lungs breathing vibration intensity and QLD(P> 0 .05);5)The MET ,QLD and EVP of the participants in the“below‐average” group ,to some extent ,fluctuate with small range and lack amplitude .Conclusions :1) .VO2 max is greatly influenced by the ventilation volume and is posi‐tively correlated with the lungs breathing vibration intensity .However ,it is uncorrelated with the cardiac output in a static situation ;2) The depth of respiration of the “normal” group (in sports) is significantly higher than the“below‐average” group ,which is possibly due to a bet‐ter oxygen utilization in metabolism and energy supply ;3) Participants with different .VO2 max levels show no significant difference of heart function in a static situation ,suggesting that par‐ticipants of the“below‐average” group didn't lose on the "starting line" ;4) Participants of the“below‐average” group lacks advantage in terms of the overall Aerobic capacity ,which + also seems to affect their cardiopulmonary function when doing sports .
