Comfortable Self-Paced Running (CSPR) can be defined as running at a subjective
intensity where one feels the most comfortable psychologically and physiologically.
This study was conducted to examine the effects of successful trials of
acute CSPR on the amount of pre- to post-exercise changes in positive mood
state. Twenty subjects completed ten 15 min CSPR trials on a treadmill
and a control trial without CSPR. Heart rate (HR), running speed,
%VO2max and Ratings of Perceived Exertion (RPE) were measured
during each trial to evaluate exercise intensity. Before and after
each trial, subjects responded to the Mood Check List (MCL-3, consisting
of "Pleasantness," "Relaxation," and "Satisfaction" subscales; a
= .913-.957) introduced by Hashimoto and Tokunaga (1995).
ANOVA showed that: (1) there were no significant differences in HR and
%VO2max among the trials; (2) there was a significant increase
in running speed (p <.001); and (3) there was a significant decrease
in RPE (p <.001). No significant mood changes were observed in
any subscales during the control trial. On the other hand, post-CSPR
"Pleasantness" and "Satisfaction" scores increased significantly following
all the trials, and a significant within-subject effect was found for the
amount of change in "pleasantness" over the 10 trials (p <.005).
The amount of change in "Pleasantness" was largest after the first trial
and decreased until the fourth trial. Ratings of "Satisfaction,"
however, did not change significantly over the trials. These results
suggest that CSPR produces post-exercise increases in pleasantness and
these mood changes are particularly evident following the first CSPR trial.
