Physical fitness, in general terms, is a person’s ability to meet the physical stresses and demands of a variety of physical activities efficiently and effectively. Physical fitness provides a personwith the capacity to perform work safely in activities of daily living, including activities required for work at home and in the workplace, for leisure-time pursuits, and for sports. The physical stresses and demands of daily living range, for example, from sitting, eating, standing, showering, and walking to the extreme physical demands of shovelling after a major snowstorm, marathon running, participating in a triathlon, and firefighting. Each of these activities requires varying degrees of cardiorespiratory endur ance (CRE), muscular strength, muscular endurance, and flexibility to perform it well. Fortunately, the physical demands of showering or walking are not great, making it quite easy for most of us to engage in these physical activities. For a small percentage of the population these activities pose difficulty. Many people are faced withdemanding tasks, such as lifting/carrying heavy objects, building, and snow shovelling, which can over-stress the body if it does not have an adequate level of physical fitness. Adequate preparation for these periodic tasks is essential to help minimize the risks of heart attack, stroke, and back injury. On the other end of the physical activity continuum are the occupations and activities that fall outside the realm of possibility for most of us. These activities require physical fitness levels and skills that are beyond our contempl ation or aspiration. They are performed by people who have been genetically gifted and have worked and trained for years to perform at the extreme levels required for these physical activities.
