M aximal aerobic power describes the functional capacity of the cardiorespiratory system and is defined as the maximum rate at which oxygen can be used during a specified period, usually during intense exercise. It is a function both of cardiorespiratory performance and the maximum ability to remove and use oxygen from the blood. The higher themeasured cardiorespiratory fitness level, the more oxygen has been transported to and used by exercising muscles, resulting in a higher level of exercise intensity that is able to be achieved. Because regular physical activity is required to maintain cardiovascular health and improve athletic performance, its measurement continues to be a focus in the health and clinical setting. Because of its underlying value as a health indicator across a variety of clinical populations, maximal aerobic power often is used as a primary or secondary end point in many research trials (10). This article will discuss the measurement of maximal aerobic power and the use of this measurement in various clinical settings, particularly as it relates to cardiovascular disease.

WHAT IS SELF-EFFICACY? T he construct of self-efficacy was introduced in 1977 by Albert Bandura, Ph.D., a psychologist at Stanford University. Self-efficacy refers to confidence in one’s abilities to successfully perform a particular behavior. For example, if you are sure that you can walk 1 mile without any difficulty, then your self-efficacy for that particular behavior is high. On the other hand, if you are quite certain that you would become exhausted and need to stop after only a few feet, then your selfefficacy for walking the mile is low (Table 1). Thus, your level of self-efficacy can have a substantial impact on your behavior.

M ost people enjoy a good trip to the mountains every once in a while: clean air, beautiful views, and fun outdoor activities. In fact, more than 34 million people travel to altitude every year. Unfortunately, there also are downsides when traveling to altitude, especially to higher elevations. Whereas everyone experiences some degree of impairment in exercise performance, many people also experience symptoms of altitude-related illnesses. The good news is that there are certain things that can be done before and during a stay at altitude that can minimize the negative effects of the high altitude, reduce the decrement in exercise performance, and make the mountain feel more like a molehill. For the purpose of this article, exercise will be defined as activities or events with a high component of sustained aerobic activity. Moderate altitude will be considered as greater than 5,280 ft (1,609 m), and high altitude will be defined as elevations above 8,500 ft or (2,600 m). Numerous vacation destinations in the United States and around the world fall into categories of moderate to high altitude (Table 1), which can place individuals at risk for discomfort and can cause reductions in exercise performance. Although the effects are greater at higher elevations, some individuals can experience mild symptoms of mountain sickness as low as Denver, CO (5,280 ft).
