Brief summary

The primary aim of this study is to explore the impact of a 20-minute aerobic exercise on inhibitory control, microvascular diameters, and brain function. The main questions it aims to answer are: 1. Is there a correlation among the level of physical activity, performance in inhibitory control, and the diameter of retinal microvasculature, and do retinal microcirculation parameters mediate this relationship? 2. Does short-term aerobic exercise (moderate and high intensity) improve inhibitory control and physiological markers, such as retinal diameter and frontal brain activation, compared to a sedentary control group?
