The function of the central nervous system, especially the cerebral cortex, declines with the increase of age, which is characterized by slow response to external stimuli, weakened memory, easy fatigue of nerve cells, slow recovery after fatigue, and weakened regulation function of the brain to various organs and system activities. Disco dance has a good stress effect on brain cells because of its diversified movements and strong sense of music rhythm, and also has a good influence on regulating the excitement and inhibition of cerebral cortex and improving the regulation of various systems. Therefore, the old people who often participate in disco dance training are energetic, quick-witted and alert.
From the above analysis, it can be seen that the advantages outweigh the disadvantages for the elderly to dance disco step by step, according to their physical strength and health level, and to have a comprehensive physical examination regularly, strengthen self-medical supervision and adjust the appropriate amount of activities.
