摘要:

文题释义:

心肺耐力:又称有氧运动能力,通常是指机体的循环系统与呼吸系统维持身体进行长时间的肌肉活动时,对营养与氧气的供应能力,以及排出代谢废物的能力,即个人的心脏与肺,将空气中的氧气携入体内,并将氧气输送到相应的组织和细胞使其加以使用的能力。它被认为是人体气体和血液交换的能动枢纽,可准确反映人体心血管和呼吸系统的整体功能状况。
CO2耐受力:有氧代谢运动过程中,人体内环境对CO2的累积耐受能力;基于波尔效应理论,当人体在运动过程中具备较高的CO2耐受力时,外周肌肉组织在特定的内环境下对氧气的摄取得到进一步优化,心肺耐力也继而得到改善。

背景:最大摄氧量作为评估心肺耐力的“金标准”,根据其概念的逻辑关系,除心肺功能外,外周组织(肌肉)对氧气的利用能力应作为心肺耐力水平的关键和决定因素。心肺功能水平是人体运动过程中氧气供应的重要保证因素,但或并不能作为氧气利用的“关键因素”。
目的:通过评估有氧代谢过程中人体CO2耐受力,探究其与心肺耐力的关联。
方法:在北京5所高校筛选92名健康在校大学生,经受试者知情同意,进行心肺运动试验采集CO2耐受及心肺耐力评估指标,并进行关联分析。试验经国家体育总局体育科学研究所伦理委员会批准。

结果与结论:①人体CO2耐受力指标与最大摄氧量相对值和绝对值存在显著正相关(P < 0.01),与身高、体质量和体质量指数存在显著正相关(P < 0.01);②通过CO2耐受指标构建的多元线性回归模型可准确解释及预测最大摄氧量的变化(校正R2分别为0.847,0.668,P < 0.01),模型验证评价提示预测值与实测值相比差异均无显著性意义(P > 0.05);③有氧代谢过程中人体CO2耐受指标与最大摄氧量之间存在高度相关,有氧代谢过程中高CO2耐受力预示着更强的心肺耐力水平,且通过数理模型发现有氧代谢过程中CO2耐受指标可在较大程度上对最大摄氧量的变化提供解释与预测。

Abstract: BACKGROUND: Maximum oxygen uptake is the “Gold standard” for evaluating cardiorespiratory endurance. According to the logical relationship of its concept, the ability of peripheral tissues (muscles) to utilize oxygen in addition to cardiorespiratory function should be the essential determinant of cardiorespiratory endurance level.  The level of cardiopulmonary function is an important guarantee factor for oxygen supply during human exercise, but it may not be used as an “essential factor” for oxygen utilization. 
OBJECTIVE: To explore the relationship between carbon dioxide tolerance and cardiorespiratory endurance during aerobic metabolism by assessing human carbon dioxide tolerance. 
METHODS: A total of 92 healthy college students were recruited from 5 colleges and universities in Beijing.  A cardiopulmonary exercise test was performed with informed consent from the subjects to collect carbon dioxide tolerance and cardiopulmonary endurance evaluation indicators for correlation analysis. The trial was approved by the Ethics Committee of the Institute of Sports Science of the General Administration of Sport of China. 
RESULTS AND CONCLUSION: There was a significant positive correlation between the index of carbon dioxide tolerance and the relative and absolute values of maximum oxygen uptake (P < 0.01), and a significant positive correlation with height, body mass, and body mass index (P  < 0.01). The multiple linear regression model constructed by the carbon dioxide tolerance index could accurately explain and predict the changes in maximum oxygen uptake (Adjusted R2=0.847, 0.668, P < 0.01). The model validation evaluation indicated no significant difference between the predicted value and the measured value (P > 0.05). To conclude, there is a high correlation between the carbon dioxide tolerance index and the maximum oxygen uptake in the process of aerobic metabolism.  High carbon dioxide tolerance during aerobic metabolism indicates a stronger level of cardiorespiratory endurance. Moreover, in the mathematical model, the carbon dioxide tolerance index during aerobic metablism can explain and predict changes in maximum oxygen uptake to a greater extent.

Key words: carbon dioxide tolerance, cardiorespiratory endurance, cardiopulmonary exercise testing, maximal oxygen uptake, arterial partial pressure of carbon dioxide
