Arousal is a physical and mental state of alertness or readiness, varying from deep sleep to intense excitement.
Arousal is a key concept in sports psychology. It refers to the level of physiological and psychological activation of a person. It is a continuum, ranging from being in a coma or deep sleep (very low arousal) to being extremely agitated or excited (very high arousal). The level of arousal significantly impacts an athlete's performance.
