Document Summary

Arousal is the general physiological and psychological activation of the body, varying on a continuum from deep sleep to intense excitement (sleep to game state) Also concerns intensity of the behaviour and interpretation.

Higher the curve, the greater the ability (upside down u) Physiological and mental changes occur when an athlete is aroused. When arousal is too low, these changes fail to occur or fail to reach the necessary level for top performance. Overarousal causes muscle tension leading to awkward movement patterns, limited range of motion, and poor coordination.
