Physical activity is not only essential for healthy growth and development, it’s also important to learning.

Research shows that physical activity - whether it’s team sports, bike riding, swimming at the beach or playground games - has positive effects on the brain and on school performance.

The positive effects of physical activity on the brain

Physical activity has a direct impact on the behaviour and development of the brain. An essay by Charles Basch of Columbia University summarised how physical activity can improve brain function:

• The flow of oxygen to the brain is increased
• The number of brain neurotransmitters is increased, which assists your ability to focus, concentrate, learn, remember and handle stress
• The number of brain-derived neurotrophins is increased, which assures the survival of neurons in areas of the brain that are responsible for learning, memory and higher thinking.

Physical activity linked to higher grades

According to the US Centre for Disease Control and Prevention (CDC), physical activity has an impact on cognitive skills such as concentration and attention, and it also enhances classroom attitudes and behaviours, all of which are important components of improved academic performance.

A study from the University of Illinois showed that children who are physically fit are more likely to perform better in school and achieve higher grades.

Children participating in the study were given electroencephalograms (EEGs) to measure brain waves and how fast the brain responds to certain stimuli. Researchers found that the brain synapses of physically fit children fired faster and stronger, and as a result those children had better language skills.

The more physically fit children were not only better at reading, they were also better at reading passages with several grammatical errors. The researchers looked at the brainwave patterns that deal with language and the ability to spot errors in grammar. The fit children had strong results with both brain wave groups, and a better understanding of nonsensical or error-filled sentences.

Another study also found positive associations between physical activity, fitness, cognitive function and academic achievement. The evidence indicated that physical activity has a relationship to parts of the brain that support complex cognitive processes during laboratory tasks. It also showed that physical activity is important for growth, development and general health.

At the Copenhagen Consensus Conference 2016, which gathered 24 researchers from eight countries and from various academic disciplines, physical activity was also found to boost brain power and academic performance, among other benefits.

The consensus statement, which was published in the British Journal of Sports Medicine, lists the reasons why physical activity is beneficial for children and adolescents aged 6-18.

Building their cognitive functioning:

• Just one session of moderate physical activity instantly boosts kids’ brain function, cognition and academic performance.
• Mastering fundamental movement skills boosts brainpower and academic performance.
• Time away from lessons in favour of physical activity doesn’t come at the cost of good grades.

Nurturing their engagement, motivation and psychological well-being:

• Physical activity boosts children’s self-esteem.
• It nurtures relationships with peers, parents and teachers.
• A caring environment that supports autonomy enhances kids’ motivation, their behaviour relating to physical activity and their general well-being.
• Regular and organised physical activity training promotes life skills (interpersonal, self-regulation) and core values like respect and social responsibility.

Supporting a culture of inclusiveness:

• Culture- and context-sensitive activities promote social inclusion.

Work hard, play harder

Being a high performer isn’t just about working hard at school. There are kids putting extraordinary effort into all kinds of fields - like school, sport, and the community.
