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 respect to a genotype or to ...
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 " [s ...
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations, and daily activities. Physical fitness is generally achieved through proper nutrition, [1] moderate-vigorous physical exercise, [2] and sufficient rest along with a formal recovery plan. [3]
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 ...
Biological rhythms are the natural cycle of change in our body’s chemicals or functions. It’s like an internal master “clock” that coordinates the other clocks in your body. The “clock ...
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 ...
A series of images that represent research (left) and practice (right) in the field of academic kinesiology. Kinesiology (from Ancient Greek κίνησις (kínēsis) 'movement', and -λογία -logía 'study of') is the scientific study of human body movement. Kinesiology addresses physiological, anatomical, biomechanical, pathological ...
v. t. e. 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.
