Defition Of Men's Fitness


What Fitness really means?

1. The state or condition of being fit, suitability or in appropriate level.
2. Good health or physical condition, especially as the result of exercise and proper nutrition.
3. Biology The extent to which an organism is adapted to or able to produce offspring in a particular environment.

Other than that, these also the definitions of fitness :


* the condition of being suitable; "they had to prove their fitness for the position"
* good physical condition; being in shape or in condition
* seaworthiness: fitness to traverse the seas..wow, can i reaaly swim that much?
* the quality of being qualified

* Fitness (often denoted in population genetics models) is a central concept in evolutionary theory. It describes the capability of an individual of certain genotype to reproduce, and usually is equal to the proportion of the individual's genes in all the genes of the next generation. 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.

* In optimisation techniques an objective measure is how good the solutions it finds are. Eg a way of building a bridge across the M4 will cost 400,000. In genetic algorithms and genetic programming, by analogy with natural selection this is called fitness. Fitness is used to guide the search by deciding which individuals will be used as future points to look for better solutions.

* The relative ability of an individual (or population) to survive and reproduce in a given environment. The 'fit' of an organism to its environment.

* The reproductive success of individuals of a particular genotype relative to the most fit genotype.

* The genetic contribution of an individual to the next generation.

* The output of each experimental setup, ie the property you are using for optimizing the parameters.

The expected contribution of an allele, genotype, or phenotype to future generations. The fitness of genes and organisms is always relative to the other genes and organisms that are present in the same population. Usually it is measured as the average number of offspring produced by individuals with a certain genotype, relative to the number produced by other genotypes.

* the degree to which an organism is fitted, or adapted, to its environment and other organisms. Higher fitness means superior ability to survive and reproduce.

* An individual's contribution, relative to other individuals, to the breeding population in the next generation. Measures of an individual's reproductive success such as its survival, fertility, and age at reproduction, are typically used as indicators of fitness. The fitness of a group of individuals (eg, a population) may be defined as the group's ability to maintain itself in its environment. It is therefore a composite measure of individual reproductive success.

* The average reproductive output of a class of genetic variants in a gene pool.

* The ability to survive to reproductive age and produce viable offspring. Fitness also describes the frequency distribution of reproductive success for a population of sexually mature adults.

* A measure of an object's ability to reproduce viable offspring.

* A measure of relative reproductive success. The only natural trait selected by natural selection.

* The competition within a community of species, which determines the survival of individuals. Those that survive can reproduce and pass on their genes to the next generation.

* (1) The ability of an individual and its corresponding phenotype and genotype to contribute offspring to the next generation. (2) The number of offspring an individual produces, not just its ability to be selected.

* the measure of a species ability to survive and reproduce

* An organism’s probability of survival and reproduction. Fitness is generally measured in terms of the different genotypes for a given locus.

* The success of an entity in reproducing; hence, the average contribution of an allele or genotype to the next generation or to succeeding generations. Relative fitness is the average contribution of an allele or genotype compared with that of another allele or genotype.

* In evolutionary theory, an individual's reproductive success to a certain higher level..

* A quantitative measure of a DMT’s success relative to the goals of the simulation. One fundamental goal of the simulation was survival of the DMT, with the possibility of additional primary or secondary goals.

* The relative competitive ability of a given genotype conferred by morphological, physiological or behavioural characters, expressed and usually quantified as the average number of surviving progeny of one genotype compared with the average number of surviving progeny of competing genotypes.

* "The relative adaptiveness of an individual organism, measured ultimately by reproductive success."

Phew!

See myfrined, there's so many definition adbout fitness. You need to understand this first to enabl eyourself train more to build muscles and body strength, especailly swmmers.
