The Relationship of Body Composition and Aerobic Exercise Capacity

Determining multifactorial phenomenon, the physical heritage also depends on hereditary and environmental conditions, in particular economic and social. To this body it is very responsive and therefore physical development can be regarded as an accurate indicator of health. Today, the food supply occurs frequently too extensive consequences such overload the body with fat and overweight installation. Also in the modern world it is confused with the new aesthetic conceptions, new trends in fashion, with frequent exposure to stress and bad habits (smoking, alcohol, drugs). In this context it may occur body homeostasis disorders or abnormal weight decrease or counterclockwise, bulimia and body fat overload. Regulation of body weight requires permanent control of the main constituents of body lean mass and fat mass, which is dependent evolution of nutrition and physical activity. Keeping an optimum composition is one means of improving and maintaining health. The aerobic capacity is an important component of physical fitness because it reflects the overall capacity of the respiratory and cardiovascular systems to cope with a prolonged and vigorous exercise. In terms of health, the high level of cardiorespiratory fitness is associated with decreased risk for certain diseases such as hypertension, coronary heart disease, obesity, diabetes, certain malignancies etc. Fight against nutritional disorders can’t be achieved only under physiological adaptation mechanisms of the body. Adaptation theory is based on physiological reasoning. Thus, we believe that differences between individuals arise from mutations or adaptations to particular climatic or geographic conditions that influenced survival at a time.
