Exams: how to use exercise to boost your revision

It’s revision season. If you’re a student preparing for upcoming exams, you might be tempted to put aside sport or other physical activity for a while in order to dedicate more time to learning.

But exercise is extremely important for academic success. Make time to be active. It may well help you revise better.

Doing some physical activity improves our ability to think and process information. My research with colleagues has shown this to be true for both primary school and secondary school pupils.

In fact, when we consider the different types of cognition, such as perception, memory and attention, the domain where physical activity has the greatest benefit is executive function. This is our ability to carry out complex, higher-level thinking. It’s the domain that is linked to academic performance.

Research has found that the beneficial effects of physical activity on cognition last for around 45 minutes. This means it is important to have regular activity breaks to maximise the boost exercise gives to revision.

You could try scheduling your revision in hour-long blocks: 45 minutes of work followed by 10-15 minutes of physical activity. This could be walking, running, body weight exercises such as squats, or even some stretching.

Perhaps most importantly, though, find an activity that you like. You’ll then be more likely to incorporate it into your revision routine. So this could be a ten-minute walk after an hour of revision, a quick five-minute break for some squats or press-ups every half hour – or a morning swim or lunchtime run.

If you can, try to go outside for these breaks. My colleagues and I have recently carried out research showing that outdoor physical activity is more beneficial than indoor physical activity for cognition.

This was true for attention, memory and executive function, which we assessed using a battery of computerised tests. So, get up, take a break, get outside, get active and boost your revision.

You can also use the boost that exercise gives you on exam days. Perhaps take a pre-exam walk – it might help calm any nerves, too.

There are many possible reasons why physical activity can boost your revision. For example, it can increase blood flow to the brain and cause the release of chemicals called neurotransmitters – the tiny signalling molecules which help our brains work more effectively.

It’s vital that schools keep in mind how important physical activity is during exam season, too. One challenge here is that, in many schools, the sports hall also becomes the exam hall. This is understandable given space requirements.

Rather than limiting opportunities for PE, though, it could seen as an opportunity to take school physical activity outside, and for teachers to find innovative ways to help their students get the extra cognition boost that comes from being outdoors.

It’s key that schools, parents and students themselves don’t stop prioritising keeping active, even when there’s so much revision to cram in. Of course, there is always a balance to be found, but physical activity boosts our cognition, revision and learning. Why would we not want to make the most of this?

I often use the term “unleashing the power of physical activity”. I encourage you to do just this during revision and exam season. Whether you (or your child, your class, or any young people you know) are revising for GCSEs, A levels, university exams or any other tests, the same applies – stay smart, and stay active.
