Move it, move it: how physical activity at school helps the mind (as well as the body)

Encouraging physical activity in the playground, in classrooms and before and after school can help.

Federal Sports Minister Bridget McKenzie recently unveiled plans to convince state education and sports ministers to ensure sport and physical education is compulsory in schools.

The physical benefits of getting kids moving have been well recognised to help prevent chronic disease and develop movement habits across their lifespan

Yet one of McKenzie’s key points, to push for mandatory physical education, was based on improving school results.

This statement is an important and positive shift in the education sector. Until recently, bodies and minds were often considered separate entities when it came to education.

Physical education has been perceived as only dealing with the “movement of the body” or the “non-thinking thing”. So historically, it has been pushed to the periphery. For example, physical education is yet to be an endorsed focus for the national senior secondary curriculum.

Yet over the past two decades, growing research has strongly recognised the inter-connections between body and mind.

How can movement help a student’s brain?

Brain processing takes up about 20% of our total metabolism through cognitive activities like memory, attention and concentration.

This cognition needs a strong flow of fuel (glucose, oxygen) and hormones to activate and enhance the brain’s capacity to perform, learn and get rid of waste.

So any prolonged sitting and inactivity can lead to negative cognitive consequences. For instance, inactivity in childhood has been linked to reduced working memory, attention and learning.

A student’s brain does not keep itself healthy independently. It is the connection with a healthy, moving body that can help improve brain performance.

Physical activity is also important in developing students’ brain structures (cells/neurons) and functioning at an early age.

The human brain is not fully developed until the third decade of life, so getting kids moving can be a powerful academic strategy.

What does the research tell us?

More studies are linking physical activity and improved cognitive function. One of the most globally recognised found primary school students’ level of cognitive function increased from just 20 minutes of walking. Students did better in an academic test and had improved attention.

Since this study, there have been many other US studies that have established links between physical activity and students’ academic performance, including from the north east (with more than 1800 students) and Texas (2.5 million students).

Several large scale reviews have also identified links between physical activity and students’ academic performance, for example, grades and test scores.

In Australia, a study of 757 primary school students across 29 primary schools found fitter children had higher NAPLAN scores. Students with specialist physical education teachers also had higher numeracy and literacy scores.

There is also evidence of improved cognitive performance (attention, memory, concentration), self-esteem, mental health (reduced depression, anxiety, stress), enjoyment and lesson engagement from school students’ participation in physical activity.
