A competitive diver experiences a dry mouth and accelerated pulse prior to takeoff due to heightened activity within the:
Show answer Hide answer
Answer: A. adrenaline
Explanation
Adrenaline triggers fight-or-flight symptoms like dry mouth and rapid heartbeat during high-stress activities. Competitive diving induces acute stress, prompting the adrenal glands to release adrenaline into the bloodstream. Heightened adrenaline circulation prepares the human body for immediate physical action under pressure. Adrenaline, also known as epinephrine, is a crucial hormone released during acute psychological or physical stress. The sympathetic nervous system stimulates the adrenal medulla to secrete hormones during perceived emergencies. Physiological arousal includes accelerated pulse, dilated pupils, and temporary inhibition of salivary secretions.
Athletes often experience these intense physiological arousal symptoms immediately before high-stakes competitions. Understanding stress physiology helps sports psychologists design effective anxiety management techniques for competitors. Chronic elevation of stress hormones can negatively impact long-term cardiovascular health in humans. Option B refers to a broad chemical class of neurotransmitters rather than the specific stress hormone. Option C names cortisone which is a corticosteroid involved in slower, prolonged stress responses. Option D names endorphins which act as natural pain relievers rather than fight-or-flight arousal agents.
