| Summary: | 碩士 === 國立體育大學 === 競技與教練科學研究所 === 105 === The American College of Sports Medicine recommends that healthy adults engage in at least 30 minutes of moderate-intensity aerobic exercise per day. However, given modern busy lifestyles, exercise is often performed less frequently, thus continuous exercise practice will become more difficult. Although ACSM’s latest guidelines for exercise prescriptions suggests that exercise may be performed in a single continuous bout, or accumulated in short bouts performed over the course of the day, much less is known about the efficacy of accumulated exercise on cognitive functions. Therefore, the purpose of this study was to determine the effects of continuous and accumulated exercise on cognitive functions by measuring event-related potential (ERP). Thirty-five healthy college-aged adults were recruited. All participants were subjected to three treatments using a within-subjects design, including exercise treatments for continuous and accumulated exercise, and a control treatment. A Stroop test was assessed after each treatment was completed. In the exercise treatments, participants were asked to perform on a stationary cycle ergometer at 65% HRR. The results revealed that those who engaged in continuous and accumulated exercise had significantly shorter reaction times on the Stroop test, as compared with those who experienced the control treatment. Additionally, increased P3 amplitude was observed only in those who performed the continuous exercise. These findings suggested that a general improvement on the Stroop test performance was found following continuous and accumulated exercise. Specifically, the beneficial effects of that exercise on both basic information processing and inhibition were found, regardless of the exercise treatments. Notably, continuous exercise may be associated with more positive effects, providing the foundation for establishing exercise prescriptions regarding cognitive functions for the young adult population.
