Physical fitness: a buffer against stress

Abstract

The purpose of this study was to determine the extent to which physically fit and unfit persons differ regarding levels of stress in their lives. The six Kraus-Weber tests were employed to assess minimal muscular function and fitness among 4,628 adult males, and a 10-item Likert-type inventory was administered to measure perceived stress. Analysis of covariance was utilized with age statistically controlled, and the results indicated that the unfit subjects perceived significantly more distress in their lives than did the adequately fit subjects. It was concluded that physical fitness may fortify the body against the demands of life and provide increased strength and hardiness. Physical fitness may act as a buffer against stress.
