Physical Activity and Brain Health Research Group


Keywords: physical activity, exercise training, exercise breaks, brain health, cognitive function, memory, attention, mind wandering, academic performance, mental well-being.


Overview of Main Activities: The research group focuses on exploring the relationship between physical activity and brain health across the lifespan. The aim of the studies conducted within the group is to understand how different types and intensities of physical activity influence mental well-being and cognitive abilities/functions in children, adolescents, adults, and older individuals.

Research Background:

Scientific research has shown that regular physical activity is associated with reduced stress, anxiety, and symptoms of depression, as well as increased psychological well-being and positive emotions. In children, regular movement supports cognitive development, improving memory and attention; in young adults, it may enhance learning skills and academic success; and in older adults, physical activity helps slow cognitive decline and supports brain plasticity – the brain’s ability to adapt, learn, and maintain mental functions during aging. 

In addition to general physical activity, the research group investigates targeted interventions, such as short physical activity breaks during sedentary work or study sessions. These short active breaks can stimulate circulation, activate brain function, and improve concentration. The group analyses how various forms of movement – from daily moderate physical activity to structured exercise programs – strengthen the connection between body and brain, promoting both mental and physical well-being.
