Mechanisms of environmental stress on human physiology

人类探索我们的星球，从海洋深处到各种条件下的极端高度。研究这些环境与人体生理之间的相互作用是我研究计划的长期重点。当人类探索这些环境时，他们很少休息。从定义上讲，在高海拔地区徒步旅行的人是在锻炼，就像登山者、潜水员、游泳者和户外运动员一样。对运动的反应是复杂的，涉及到身体的所有系统，但为了方便起见，研究通常只在休息状态下进行。因此，我的研究目标是探索环境与人类的互动，特别关注运动。

Humans explore our planet from depths of the oceans to extreme heights under a variety of conditions. Studying the interaction between these environments and the physiology of the human body is the long-term focus of my research program. When humans are exploring these environments, they are seldom at rest. Trekkers at altitude are exercising by definition, as are climbers, divers, swimmers, and outdoor athletes. The response to exercise is complex, involving all the systems of the body, but so often research is only conducted in the resting state as a matter of convenience. My research goals are thus to explore the environment-human interaction, with a special focus on exercise. The first research theme is to study the difference between two methods of simulating altitude: a) lowering the pressure in the environment, and b) lowering the percentage of oxygen in the environment. and the interaction between diving and exercise. Typically scientists think of the two methods almost interchangeably, although there may be important differences between these two techniques and how they affect the human body. The second theme focuses on the long-held belief and recommendation that it is unsafe to exercise after diving. This recommendation has been traditionally taught to all divers, yet it is not based on science. Some recent studies have indicated that exercise may not be dangerous after diving, but much more research needs to be done in this area. Thus, the short-term objectives of this research program are threefold: To investigate the mechanism of the differences between two types of simulated altitude. To assess how the differences between two types of simulated altitude are affected by exercise To investigate how exercise after diving affects heart, lung and blood vessel function
