Abstract

The volunteers for this study were eight male college students, aged 18-23 years. Each subject performed the simple reaction time trials under the various levels of exercise. Physiological measures of exercise-induced activation were chosen among the heart and lung functions. The theoretical relationship between activation and performance is represented by an inverted U-curve. The optimal performance of heart rate (HR) seemed to be demonstrated at the point of HR of 100 bpm; that of respiratory rate (RR), below the point of RR of 30breaths/min; that of V_E, below the point of V_E of 30 1/min; that of Vo_2, below the point of Vo_2 of 1.2 1/min; and that of energy expenditure, below the point of calory of 8 Cal/min. HR as an indicant of exercise-induced activation forms an inverted U in the relationship between activation and performance. The implications of these findings are discussed.
