目的 :探讨模拟不同船舱环境对血浆血管紧张素Ⅱ (AngⅡ )及抗渡海运动病能力的影响 ,为我军特殊环境的预适应体能训练提供依据。方法 :以解放军体育学院学员二旅 80名新学员为对象 ,随机分成两组 ,一组接受良好船舱环境 ,另一组经历高温高湿、低氧、异味等恶劣船舱环境 ,采用Graybile运动病评价体系分析受试者渡海运动病情况 ,放免法测定血浆AngⅡ。结果 :与良好船舱环境相比 ,经历恶劣船舱环境后受试者渡海运动病发病率明显增高 ,发病程度明显加重 ;血浆AngⅡ浓度显著下降 (P <0 0 1)。结论 :恶劣船舱环境可削弱人体的抗渡海运动病能力 ,血管活性物质平衡失调可能是原因之一。
Objective: To investigate the effects of simulating different cabin environments on plasma angiotensin Ⅱ (Ang Ⅱ) and anti-sea-crossing motion sickness, and to provide basis for pre-adapted physical training of our army’s special environment. Methods: A total of 80 new trainees from the Second Brigade of People’s Liberation Army Physical Education College were enrolled in this study. They were randomly divided into two groups. One group received good cabin environment and the other group experienced harsh cabin environment with high temperature and humidity, hypoxia and odor. Graybile motion sickness evaluation System analysis of the subjects cross-sea motion sickness, radioimmunoassay plasma Ang Ⅱ. Results: Compared with the good cabin environment, the prevalence of cross-sea movement was significantly increased and the severity of the disease was significantly increased. The plasma AngⅡ concentration was significantly decreased (P <0.01). Conclusion: The harsh cabin environment can weaken the body’s ability to resist sea-crossing motion and the imbalance of vasoactive substances may be one of the reasons.
