摘要: 目的: 在整体整合生理学医学理论的指导下,通过分析正常人运动期间心肺代谢等多系统功能整体整合的连续动态变化,探讨正常环境运动状态下呼吸反应模式的调控机理。方法: 选正常志愿者5名,在美国洛杉矶加州大学Harbor-UCLA医学中心分别进行动脉置管,在常温室内空气状态下完成症状限制性最大极限心肺运动试验(CPET)。在运动过程中,连续测定肺通气指标及每分钟动脉取样的血气分析指标的变化,对CPET期间呼吸气体交换和血气指标的动态变化进行统计分析。结果: 在CPET期间,随着运动功率逐步递增,分钟摄氧量(每呼吸摄氧量×呼吸频率=每搏摄氧量×心率)和分钟通气量(潮气量×呼吸频率)均呈现近于线性渐进性递增(与静息状态比较,P<0.05~0.001);在运动超过无氧阈和呼吸代偿点后,分钟通气量的上升反应更加显著。结论: 人体在运动过程中,为了克服自行车功率计的阻力而发生代谢率改变,呼吸随代谢改变而变化,高强度运动时酸性代谢产物堆积更加加剧呼吸反应。

Abstract: Objective: Under the guidance of the holistic integrative physiology medicine, we reanalyzed the data during symptom-limited maximum cardiopulmonary exercise testing (CPET) in order to investigate control and regulatory mechanism of breathing. Methods: This study investigated 5 normal volunteers who accepted artery catheter, performed CPET room air. Continuous measured pulmonary ventilation parameters and per minute arterial blood gas (ABG) analysis sample parameters during exercise. All CPET and ABGdata changes were standard analyzed and calculated. Results: With gradually increasing power, minute oxygen uptake(every breath oxygen uptake × respiratory rate = O2 paulse × heart rate) and minute ventilation (tidal volume × respiratory rate) showed nearly linear progressive increase during the CPET(compared with the rest stage, P<0.05 ~ 0.001); Minute ventilation increased even more significant after the anaerobic threshold (AT) and respiratory compensation point. PaO2 was increased at recovery 2 minutes (P<0.05); PaCO2 was decreased after anaerobic threshold 2 minutes (P<0.05); [H+]a was increased from AT (P<0.05), and rapidly raised at last 2 minutes, remained high at recovery. Lactate was increased rapidly from AT (compared with resting,P<0.05);bicarbonate decreased rapidly from AT ( compared with resting,P<0.05) and it's changed direction was contrary to lactic acid. Conclusion: In order to overcome the resistance of the power during exercise, metabolic rate othe body increased, respiratory change depend upon the change metabolism, and the accumulation of acidic products exacerbated respiratory reactions at high intensity exercise.
