Physical fitness – Simple English Wikipedia, the free encyclopedia

Physical fitness is the ability to be physically active, to move and respond to the environment. People can take various tests to measure their physical performance. Such tests are necessary for some occupations, such as soldiers and firefighters.

Physical fitness has two components: general fitness (a state of health and well-being) and specific fitness (the ability to perform specific aspects of sports or occupations).

The President’s Council on Physical Fitness and Sports — a study group sponsored by the United States Government — declines to offer a simple definition of physical fitness. Instead, it developed the following chart:[1]

Physiological Health related Skill related Sports
Metabolic Body composition Agility Team sport
Morphological Cardiovascular fitness Balance Individual
Bone integrity Flexibility Coordination Lifetime
Other Endurance Power Other
Muscle strength Speed

Health related components: those factors that are related to how well the systems of your body work.

Fitness in biology is the relative ability of an organism to survive and pass on its genes to the next generation.[1]p160 It is a central idea in evolutionary theory. Fitness is usually equal to the proportion of the individual’s genes in all the genes of the next generation.

Like all terms in evolutionary biology, fitness is defined in terms of an interbreeding population, which might or might not be a whole species. If differences in individual genotypes affect fitness, then the frequencies of the genotypes will change over generations; the genotypes with higher fitness become more common. This is the process called natural selection.

An individual’s fitness is caused by its phenotype, and passed on by its genotype. The fitnesses of different individuals with the same genotype are not necessarily equal. It depends on the environment in which the individuals live, and on accidental events. However, since the
