Fitness is an essential part of life. Having the ability to move around and sit up without any pain is considered to be one of the most basic requirements of being alive. Fitness is necessary not only for our bodies but also for our mental health. In fact, the concept of fitness has been around for centuries. Ancient societies believed that physical activity was necessary for happiness, health, and emotional well-being.
Fitness has many scientific names, some of which are strength training, resistance training, power training, and aerobics training. The scientific study of fitness has many important areas of focus. Physical fitness, more specifically, the capacity to perform various tasks and parts of sports, is a measure of general health and well being and, more importantly, the capacity to perform different kinds of activities. Physical fitness is usually achieved through proper nutrition, regular moderate-to vigorous physical activity, adequate rest, and adequate sleep.
An ecological fitness scale is used to determine the individual’s overall health by considering the influence of natural forces on the organism. These forces can be climate, food availability/use, current health status, life style, geographic location and so on. Ecological fitness is the sum of all the components of fitness that compose the organism. A high ecological fitness level indicates good health, while a low ecological fitness level indicates a poor health condition. Therefore, in order to maintain or improve the health condition of an individual, it is important to consider all the possible influences on the organism and take necessary measures to maintain the necessary levels of fitness. An optimum level of fitness can be maintained by the combination of healthy living, adequate exercise and a nutritious diet.
Fitness is a desirable trait in most people, because it directly affects your quality of life. In order to have good health, you need to have a good body structure as well as a healthy mind. Proper nutrition ensures that you become physically fit. An ideal weight and the amount of physical activity are crucial for the maintenance of a healthy body system. Therefore, fitness has both psychological and physiological elements. A well-balanced fitness program ensures the mental as well as the physical well-being of an individual.
The two theories of Fitness define the nature of fitness and the contribution made by fitness in the existence and survival of a species. Fitness is known to be a product of natural selection, which means that certain organisms survive by virtue of their ability to adapt to changes in their environment. A person who is fit has more chances of surviving and passing on his genes to his offspring. Fitness therefore is an inherited trait, which means that a healthy body system is passed on from parents to children. A good example of fitness is stamina, which is defined as the capacity to work for a prolonged period of time in a particular body part, such as the heart or the lung.
Fitness, on the other hand, is defined as the ability to function at optimum levels despite unfavorable circumstances, including physical stress, disability, illness, and anemia. Therefore, even if one has a poor genetic make up, he can still have a good health, if he is able to engage in some form of physical activity regularly. One must remember though that the concept of fitness may not be applicable everywhere. It could be different depending on what is meant by fitness. For instance, a person who wants to build up his athletic strength could be said to be pursuing fitness, rather than physical activity.
