Abstract
This study investigated a possible relationship between exercise intensity and mood alteration that commonly is associated with physical activity. 91 college students completed the Profile of Mood States before and after 20 min. of jogging at three intensities: 55%, 75%, and 79% of age-adjusted maximum heart rate on different occasions. Exercisers also completed a demographic inventory, a Lie Scale, and the State-Trait Anxiety Inventory. Contrary to our expectations, the interaction between exercise intensity and pre-post mood benefits was not significant. Supporting the manipulation of exercise intensity, the univariate interaction between exercise intensity and pre-post exercise scores on Fatigue was significant. Joggers reported short-term mood benefits on the combined subscales of the Profile of Mood States, and each subscale contributed to the benefits. Thus, regardless of the low- or moderate-intensity, participants reported that they “felt better” after exercising.
