Physical fitness comprises two related concepts: general fitness (a state of health and
well-being), and specific fitness (a task-oriented definition based on the ability
to perform specific aspects of sports or occupations). Physical fitness is generally
achieved through correct nutrition,exercise, hygiene and rest.
Specific or task-oriented fitness is a person's ability to perform in a specific
activity with a reasonable efficiency: for example, sports or military service. Specific
training prepares athletes to perform well in their sports.
100 m sprint: in a sprint the athlete must be trained to work anaerobically throughout
the race, an example of how to do this would be interval training.
Marathon: in this case the athlete must be trained to work aerobically and their
endurance must be built-up to a maximum.
Many fire fighters and police officers undergo regular fitness testing to determine
if they are capable of the physically demanding tasks required of the job.
