I have often wondered what controls my responses during a competition. There are many stimuli that affect my body such as anxiety, chills, stress during diet and weighing, tiredness, the need to rest before the competition, and thoughts about my performance. The nervous system controls all my thoughts, feelings, and movements at all times. How? Scientists have shown that the nervous system receives messages about sensations of touch, hearing, and vision directed through the spinal cord and nerves. The brain integrates the signal and conducts a response to the organs of the human body.
