There are two distinct parts to consider when discussing fitness. First, physical fitness refers to your ability to do everyday activities and tasks, as well as the ability to do them well. Second, mental fitness refers to your attitude toward your health, your body, and your life in general. Mental fitness, in turn, is usually defined through proper sleep, healthy eating, balanced exercise, and adequate rest. Together, physical and mental fitness to provide a complete picture of your well-being.
Muscles and fibers came in two forms: Hard and soft. Hard fibers are those that are found in bone, while soft fibers are those that are found in muscles, tendons, ligaments, and other connective tissues. Hard muscles are those that have a great deal of tension, which is one of the ways that we measure muscular power. Soft muscles are those that are not as tense and do not require as much effort to maintain. Thus, the definition of “fitness” typically includes both types of fiber.
Physical fitness has a lot to do with what is known as the Theory of Natural Selection. The Theory of Natural Selection suggests that if an organism can survive, it will reproduce. Fitness then is determined by survival, which itself is influenced by genes (sexually transmitted genetic material). Therefore, one can think of fitness as the traits that gene copies successfully and that help the organism to reproduce. The theory also states that fitness increases with age. For instance, elderly individuals can be considered “fit” since they have more mature genes and thus, have less chance of suffering from health problems.
One of the most compelling theories about fitness and its relationship to health and disease is called the Fitness Hypothesis. The Fitness Hypothesis proposes that there are three different facets to fitness: individual trait fitness, group trait fitness, and physiological fitness. Individual trait fitness refers to the amount of variation within an individual’s genetic makeup; fitness throughout the population; and fitness differences between breeds. Group trait fitness refers to differences in physical activity and ability. Lastly, physiological fitness refers to the ability to function within the body system.
Individual traits and group trait fitness are the two main components of fitness. However, one component of fitness is currently being debated. The debate concerns the definition of “sport”. For years, golf has been considered a sport. Golf, however, has many elements beyond the typical golfer’s ability to hit a ball the hundred yard dash.
Currently, there are three major crossfit athletic organizations: the United States Olympic Team, the National Crossfit Association, and the International Olympic Committee (IOC). Each organization has a working definition of what is considered to be an acceptable level of fitness. Athletes may meet these criteria, but they are usually not considered to be in the best shape possible. In contrast, the Olympic movement does have a set standard for what is considered to be the best physical condition for an athlete. The current IOC definition for an Olympic event is an athlete who can demonstrate the ability to lift weights using maximal strength to complete each set of exercises without stopping for more than five seconds.
