Abstract

The purpose of this study was to examine the psychophysiological factors that determine the exercise intensity (%Vo2max) of comfortable self-paced running. Seventeen male students ran on a treadmill for 15 minutes at a comfortable self-established pace and the relationship between psychophysiological variables and %Vo2max was investigated. Physiological factors, such as the heart rate, running speed and the Rating of Perceived Exertion (RPE) during exercise, were measured, and the %Vo2max and anaerobic threshold (AT) of the subjects were estimated based on the respiratory gas obtained during exercise. In addition, the blood lactate and plasma catecholamines, which indicated the response of blood biochemistry to exercise, were measured both before and after exercise. Psychological variables, such as personality, a type A behavior pattern, mood state and stress symptoms were also measured during the experiment. The %Vo2max during exercise indicated a moderate exercise intensity level, 60.7±9.60%. According to Pearson's correlation coefficients, the %Vo2max was significantly related to AT, the heart rate and running speed during exercise as well as the blood lactate and plasma catecholamine after exercise. Psychological variables such as a type A behavior pattern and personality trait, i.e. a lack of Agressiveness (Ag). General Activity (G), Rhathymia (R), or Ascendence (A), were positively correlated with the %Vo2max. Using the %Vo2max as a criterion for AT, personality trait and a type A behavlor pattern, the results of a multiple regression analysis indicated that a significant BETA of AT (BETA=.486, p <.05) and a type A behavior pattern (BETA=.460, p <.05) could be recognized. The data thus suggested that those with a high AT and a type A behavior pattern can therefore be expected to run at a higher intensity of comfortable self-paced running. The findings of this study therefore suggest that the exercise intensity of comfortable self-pace running depend on psychophysiological factors, AT and the presence or absence of a type A behavior pattern.
