Evolutionary biology. Fitness (often denoted or ω in population genetics models) is a quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype. Fitness can be defined either with ...
Herbert Spencer coined the phrase "survival of the fittest". " Survival of the fittest " [1] is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success. In Darwinian terms, the phrase is best understood as ...
In evolutionary biology, fitness landscapes or adaptive landscapes (types of evolutionary landscapes) are used to visualize the relationship between genotypes and reproductive success. It is assumed that every genotype has a well-defined replication rate (often referred to as fitness). This fitness is the "height" of the landscape.
The bottom line. Metabolic age is more of a fitness term than a medical one. It’s a way to compare your basal metabolic rate (BMR) to other people your age. It can offer a general idea of your ...
Muscular hypertrophy can be achieved through weightlifting at the gym. But you need to continuously break down and challenge muscles in order to see growth. A protein-rich diet is also important ...
Your metabolism uses calories and oxygen to make and release energy in a form the cells in all your organs and tissues can use. Your metabolism affects how much of that energy your body uses up ...
In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964: An individual's own child, who carries one half of the individual's genes, is defined as one offspring equivalent. A sibling's child, who will carry one-quarter of the individual's genes, is 1/2 offspring equivalent.
Flexibility: the ability to move muscles and joints through a full range of motion. Body composition: your body’s ratio of fat mass to fat-free mass like muscle and bone. Summary. The five ...
