fitness

The ability to undertake sustained physical exertion without undue breathlessness. Fitness is associated with a sense of physical and mental well being. The achievement of fitness is possible only by making regular demands on the body to perform physical tasks. As fitness improves the bulk and strength of the voluntary muscles and the force and pumping efficiency of the heart muscle increase. The respiratory muscles perform more effectively. The subject is able to perform more work within the limits of the rate at which oxygen is supplied by the lungs and circulation (aerobic exercise). Recovery from fatigue is more rapid, a higher degree of muscle tension can be attained, the muscles are able to utilize glucose and fatty acids in the presence of less insulin, and the liver is better able to maintain the supply of glucose to the blood, and hence to the muscles, during strenuous exercise. The energy-producing elements in the muscle cells (the mitochondria) increase in size and number.

fitness

the ability of an organism to transfer its genes to the next generation. Organisms favoured by SELECTION (natural or artificial) have a high fitness, while those subjected to adverse selection pressure have a low fitness. Thus, under conditions of insecticide treatment, resistant members of an insect population will have a high fitness and produce more offspring as compared to susceptible individuals that have a low fitness.
