Question 1

Explain the relationship between exercise and cardiovascular Energy. Explain the structure and pathway of blood through the heart.

Through exercise, the cardiovascular system performs 3 functions:

1) Adapt the blood flow to the muscles. 2) Eliminate waste products. 3) Collaborate in the process of thermoregulation (Ackerknecht, 1971).

The response is regulated by different mechanisms. One of the most important is NERVOUS, which is an increase in sympathetic nerve activity and decreased parasympathetic activity; mediated by two controls: a) Central nerve impulses are descendants of the cerebral cortex to the vasomotor center in the medulla (Fábrega, 1997). This control is started simultaneously with the motor command acting muscles, is called "anticipatory response". b) Reflection, which occurs after the start of muscle contraction and are impulses that originate in muscle and joint receptors (Farmer, 2000).

The use of dietary supplements to support and improve Energy may be desirable; however, long-term use of some supplements can be harmful when they are consumed in high amounts. Further, some supplements may potentially interact with foods and other drugs regardless of their sources—natural or chemical.
