Catecholamine is an important neurotransmitter containing catechol and amine-type substances. It plays an important role in cardiovascular activity and neuroendocrine regulation. Exercise, as a stressor, may increase the secretion of catecholamine, which may reflect the excitement of the sympathetic nervous system and indicate the stimulation intensity of exercise stress on athlete's psychology. Based on literature study, the article introduces the structure and physiological/biochemical functions of catecholamine and the latest development of study on exercise and catecholamine. It discusses the affection mechanism of exercise on catecholamine and suggests that catecholamine be used as a characteristic index for exercise-induced anxiety. |
