In the past, goal-setting research in the exercise performance domain
has been plagued with methodological problems, resulting in inconclusi
ve support for the theory. This study attempts to overcome these probl
ems and provide support for goal setting, as has been found in cogniti
vely based tasks. Consistent with the predictions of the theory, the r
esults show that specific, difficult goals lead to greater performance
improvements than ''do your best'' goals or no goals. Further, partic
ipants with higher goal commitment and more self-report personal goals
had the highest rates of improvement. Neither variations in the imple
mentation of specific, difficult goals nor self-handicapping explained
much variance in exercise performance. Results are discussed in relat
ion to the general efficacy of goal theory in the exercise performance
domain.
