Abstract

Several studies have shown that repeatedly performing tasks that involve self-control could improve self-control strength. The purpose of this study was to test whether intensive physical exercise involving long-term health-related goals could enhance self-control among college students. Study 1 was conducted to investigate the effects of intensive exercise on self-control. Changes were measured using a delay discounting task(DDT), a behavioral task measuring impulsivity. College students who took the Intensive Physical Training(IPT) course(n=199) and a less intensive PE course involving a single sports activity (control, n=156) performed the computerized DDT at the beginning and end of the course. After administering the DDT, significant decreases in impulsivity were observed only in the IPT students. Study 2 was conducted to replicate the results of study 1 as well as explore whether increased self-control via exercise can be generalized to other behaviors. Students who participated in the IPT course(n=193) and the less intensive PE course(n=131) completed the DDT and general self-control behavior questionnaire at the beginning and end of the course. Results revealed that the impulsivity of only the IPT students decreased significantly, reaffirming the results of study 1. However, no generalization effects were found in other behaviors involving self-control. Clinical and research implications as well as limitations are also discussed.
