Cognitive functions, also known as intellectual functions, encompass thinking, understanding, memory, language, computation, and judgment, and are performed in the cerebrum. The prefrontal cortex (PFC), located in the frontal lobe of the cerebral cortex, handles these functions. Studies have shown that exercise improves cognitive function through mechanisms such as enhanced cerebral blood flow, structural changes in the brain, and promotion of neurogenesis.
However, 81% of children globally do not engage in enough physical activity, leading to high levels of sedentary behavior and insufficient exercise. This lack of physical activity raises concerns about its negative impact on children's healthy brain development and cognitive function. A recent study published on July 6, 2024, in Volume 14 of Scientific Reports , by doctoral student Takashi Naito from the Graduate School of Sport Sciences, Waseda University, along with Professors Kaori Ishii and Koichiro Oka from the Faculty of Sport Sciences, Waseda University, offers insights into potential solutions.
The study investigated the effects of short-duration and light-intensity exercise on increasing cerebral blood flow in children. "Our goal is to develop a light-intensity exercise program that is accessible to everyone, aiming to enhance brain function and reduce children's sedentary behavior. We hope to promote and implement this program in schools through collaborative efforts," says Naito.
