Abstract : Reguler exercise and physical activity can reduce the risk of chronic illness and death while also improving body composition and cardiorespiratory performance. Compared to conventional training approaches, higj intensity interval training is an effective and time-saving training strategy to improve fitness on young adults. On the other hand, little is known about how they affect cognitive function. As of right now, there are no recommendations for physical activities that enhance cognitive function. Thus, the purpose of this research was to ascertain how HIIT affected young adults who were sedentary in terms of cognitive function. The method of this study used an experimental method on 20 sedentary young adults. Samples were divided into two groups, the control group and the HIIT group. HIIT sessions consisted of intervals of 60 second work at 85% HRmax and 120 second interval period at 40% HRmax, three times/wk for four weeks. Cognitive function was measured using the stroop task test. The results showed that there were a significant increase in cognitive function in the HIIT group (p=0.00). There were a significant difference in cognitive function between the HIIT and the control group (p=0.00). In conclusion, HIIT over four weeks can increase cognitive function in sedentary young adults.
