*** Definition of cardiorespiratory fitness

Cardiorespiratory fitness has been defined by the Sports Medicine Manual as one of the most important things that make up physiological fitness, which is closely related to the supply of oxygen to the respiratory and circulatory systems of the body when a person performs prolonged and continuous physical exertion.

Scientists have confirmed that respiratory fitness depends on a set of unchangeable factors, no matter what happens, such as age and gender, in addition to genetic factors and genes, although some consider it one of the most important factors and indicators that determine the extent of physical activity, and it is an effective factor in determining The relationship between health and physical activity.

Accordingly, physical health experts confirmed that the indicators of obesity in the abdominal or waist area and cardiorespiratory fitness indirectly indicate the existence of several links between abdominal obesity and physical activity.

Measuring cardiorespiratory fitness is very important and necessary because it provides an important way to diagnose a range of health problems that the body may suffer from. It also helps to measure the amount of effort that an individual can do, in addition to measuring the intensity and strength of exercise that can It is performed by the individual, because the body needs a large amount of oxygen when performing exercise, in addition to a certain level of carbon dioxide and lactic acid (metabolic waste products resulting from exercise), and the body continues to deplete oxygen until it reaches a certain amount of effort that will stop Therefore, we find that the higher the level of cardiorespiratory fitness is regular and better for the individual, the longer the duration of exercise is also.

Among the most important activities that develop cardiorespiratory fitness are walking, swimming, cycling in addition to running.
