Heart exercise protect your brain too &lt; Truth &gt;

Evidence suggests that regular aerobic exercise can reduce the development of certain cancers is strong. This time is even stronger evidence suggesting regular aerobic exercise can have a profound impact on cardiovascular health. With regular aerobic exercise, the efficiency of the heart, which produce many beneficial effects for the body increases. Improving the efficiency of the heart can also lead to a reduced risk of developing heart disease.

Improve the efficiency of heart: heart exercise

The efficiency of the heart and cardiovascular health can be determined by several different methods. One method is to measure the resting heart rate of a person. Lower after a training period of aerobic exercise resting heart rate indicates greater heart exercise efficiency of the heart. heart exercise The stroke volume (amount of blood ejected by the heart with each beat) increases, which basically means that the heart muscle is not pumping the number of times to get enough blood to the body. With the practice of aerobic exercise, heart exercise the heart muscle is strengthened and not have to work as hard as he did before the aerobic exercise practice.

For example, rest, untrained individual may have a rate of 70 beats per minute (pm) and a stroke volume of 71 ml / heartbeat. heart exercise Which corresponds to a cardiac output of 5000 ml / minute. On the other hand, a person with the same aerobic training heart rate will have a resting heart rate of 50 beats per minute and a stroke volume of 100 ml / beat. heart exercise [1] The trained person is able to get enough blood to your body with fewer beats the untrained individual. It just shows an adaptation of the body through the practice of regular aerobic exercise.

Other adaptations that accompany the practice of regular aerobic exercise include increased blood volume, heart exercise increased blood flow to the muscles, heart exercise and increase in size and mitochondrial density. This increase in mitochondrial density is important for the use of fat as fuel during submarginal aerobic exercise. When a molecule of fat must be vented for use as a fuel is decomposed into a fatty acid and a glycerol molecule. heart exercise The fatty acid is carried by the blood to the mitochondria where it is processed for use as fuel. With an increase in the number of mitochondria in muscle cells, the body may be treated using more fuel and fatty acids. This retains the potential energy stored as carbohydrates for other uses. [2] In other words, the body can use fat more efficiently during aerobic exercise and carbohydrate save precious fuel heart exercise.
