Motion is an inherent property of our body and inactivity is the mother of many diseases. Motion determines our posture and different bodily functions. During the evolution process the direct link had been established between the motion functions and proper working of our internal organs. Physical activity stimulates and increases heart rate which pumps more oxygen to the brain; it enhances functions of each organ and system.
According to the studies over the last century physical activity of a human has been reduced 100 times compared with the previous centuries. It is natural as these days mental work is more and more preferred and is a more demanding type of job than physical work. It has terrible effects on our physical health. Inadequate physical activity can cause neural and reflex action dysfunctions which results in dysfunction of cardiovascular activity. This process can lead to the development of different diseases like atherosclerosis which is known as the disease of the 21st century.
Physical inactivity increases the risk of heart and cardiovascular diseases. People who lead less active style of life are under the risk of premature death due to the ischemic heart diseases two times more than those who are physically active. Inadequate physical activity is closely related with strokes, diabetes, colon cancer, breast cancer, osteoporosis and an early death. In order to keep fit and healthy our body needs a certain amount of physical activity.
It is worthwhile to mention that physical activity should be permanent. Slowly developing diseases can lead to weakening our physical abilities to that extent that we will be unable to restore our usual physical rhythm even after making great efforts.
Physically inactive life leads to reduced heart activity which causes weakening of heart muscle, blood pumping ability and decreased blood volume distribution. Blood-vessel tone is worsened, blood pressure – reduced and it is then when body tissues experience the lack of oxygen and gradually the pathological processes start to develop and different diseases emerge. All these lead to heart stroke, hypertonia, the major disease of our age – obesity, etc. It is a well-known fact that people engaged in mental work are two or three times more likely to have myocardial infarction than those who work physically or lead an active life.
Physical exercises or fitness training done on regular basis can slow down and stop the progress of some pathological diseases.
It should be taken into consideration that one should start with adequate amount of physical training and that physical training should be increased gradually and moderately and not all of a sudden. We should keep it in mind in the beginning of our physical training as the sudden excessive physical activity after a long hypodynamic period (or period of low physical activity) can lead us to serious health damage.
