At the start of this year, I decided to make a New Year’s resolution to run more. It’s a popular choice, as many people aim to exercise more when the new year begins. In fact, 44% of Americans set this goal, and 12% of them even download a new app to help them get started. My personal goal was to train for a race across the Sydney Harbour Bridge.
We all know that regular exercise is great for our bodies, but did you know it’s also fantastic for our brains? A study explored this by dividing people into two groups. One group attended an aerobic exercise class every week for a year, while the other group participated in a stretching class. The aerobic group, who walked briskly for forty minutes each week, showed better results in memory tasks. These tasks involved remembering the locations of small dots on a computer screen. The improvement in their memory was linked to changes in their brain structures due to exercise. After a year, their hippocampus, the part of the brain responsible for memory and learning, grew by an average of 2%. On the other hand, the stretching group saw a decrease in hippocampal size by 1.42%.
It’s not surprising because our brains can start to deteriorate as early as age 30. Studies show a strong connection between physical activity and brain function in children. For example, 9- and 10-year-olds who did well on fitness tests had larger hippocampal volumes and performed better on memory tasks.
Exercise doesn’t just strengthen your muscles; it also strengthens your brain cells. Scientists believe this is partly due to a protein in the brain called BDNF, which stands for brain-derived neurotrophic factor. Activities like running boost the production of BDNF, which helps grow dendrites (the branches of neuron cell bodies) and strengthens synapses (the connections that allow neurons to communicate).
BDNF enhances the connectivity between neurons and brain structures like the hippocampus, which is vital for memory. From an evolutionary perspective, if you’re out running or walking to find food or shelter, increased BDNF in your brain helps you remember important information.
So, when you go jogging, you’re not just exercising your body; you’re also giving your memory a workout! This might change how you think about your New Year’s resolutions, your morning run, or even how you think in general.
Keep a journal for a week where you document your daily exercise routine and any memory-related tasks you perform, such as studying for a test or remembering a list. Reflect on any changes you notice in your memory or concentration. This will help you understand the connection between physical activity and memory improvement.
Create a 3D model of the brain, focusing on the hippocampus. Use clay or other craft materials to build your model. Label the parts and explain how exercise affects the hippocampus and memory. This hands-on activity will reinforce your understanding of brain anatomy and the impact of exercise.
Research more about the protein BDNF and its role in brain health. Prepare a short presentation to share with your class, including how exercise influences BDNF levels and why this is important for memory. This will enhance your research and public speaking skills while deepening your knowledge of the topic.
Design a simple experiment to test memory before and after a short exercise session. Use a memory game or a list of words to memorize. Conduct the experiment with classmates and analyze the results to see if exercise had an impact. This activity will help you apply scientific methods and understand the effects of exercise on memory.
Organize a class challenge where you combine physical activities like running or jumping jacks with memory tasks. For example, after a short run, try to recall a sequence of numbers or words. This fun and interactive activity will demonstrate the immediate effects of exercise on memory and cognitive function.

This year, I made a New Year’s resolution to do more running, like many others who are likely to make similar resolutions. In fact, 44% of Americans tend to resolve to exercise more, with 12% of those starting fresh on New Year’s Day downloading a new app. I decided to train for a race across the Sydney Harbour Bridge.
Of course, regular exercise is beneficial for your body, but the health benefits extend beyond that. Physical exercise is also good for your brain. One study divided participants into two groups: one that attended an aerobic exercise class every week for a year, and another that participated in a stretching class. Those in the exercise group, who engaged in forty minutes of aerobic walking weekly, showed improvements on spatial memory tasks, where they had to remember the locations of small dots flashed on a computer screen. This improvement was directly linked to increases in certain brain structures due to exercise. After one year, their hippocampus, the brain’s memory and learning center, increased in size by an average of 2%. In contrast, those in the stretching group experienced a decrease in hippocampal size by 1.42%.
It’s not surprising, as brain deterioration can begin as early as age 30. Data suggest a significant positive relationship between physical activity and cognitive functioning in children. In one study, 9- and 10-year-olds who performed better on fitness tests had larger hippocampus volumes and better performance on memory tasks.
In addition to strengthening muscle cells, exercise also strengthens brain cells. Researchers believe some benefits stem from a protein in the brain called BDNF, which stands for brain-derived neurotrophic factor. Exercise, such as running, stimulates the production of BDNF, which promotes the growth of dendrites (the branches of neuron cell bodies) and strengthens synapses (the structures that allow neurons to communicate).
BDNF increases connectivity between neurons and brain structures like the hippocampus, which is crucial for memory. From an evolutionary standpoint, if you’re out on a run or aerobic walk searching for food or shelter, an increase in BDNF in your brain will enhance your ability to remember what you find.
So, jogging can actually jog your memory! Exercising your brain cells might change the way you think about your New Year’s resolutions or your morning run, or it might just change the way you think in general.

Exercise – Physical activity that is planned, structured, and repetitive for the purpose of conditioning the body. – Regular exercise can improve your overall health and reduce the risk of developing certain diseases.
Memory – The ability to store, retain, and recall information and experiences in the brain. – Studying regularly can help improve your memory and make it easier to recall information during exams.
Brain – The organ in the head that controls thought, memory, emotion, touch, motor skills, vision, breathing, and every process that regulates our body. – The brain is constantly processing information from the world around us, even when we’re asleep.
BDNF – Brain-Derived Neurotrophic Factor, a protein that supports the growth, development, and maintenance of neurons in the brain. – Exercise has been shown to increase levels of BDNF, which can enhance learning and memory.
Hippocampus – A region of the brain that is associated with memory formation and spatial navigation. – The hippocampus plays a crucial role in converting short-term memories into long-term ones.
Neurons – Specialized cells in the nervous system that transmit information through electrical and chemical signals. – Neurons communicate with each other to process information and control bodily functions.
Activity – Any movement that requires energy expenditure, often used to describe physical actions that promote health. – Engaging in physical activity like walking or cycling can help maintain a healthy weight.
Fitness – The condition of being physically fit and healthy, often achieved through regular exercise and proper nutrition. – Maintaining good fitness levels can improve your mood and boost your energy.
Stretching – Exercises designed to improve flexibility and prevent injury by lengthening muscles and tendons. – Stretching before and after workouts can help prevent muscle soreness and improve performance.
Resolution – A firm decision to do or not to do something, often related to personal goals or changes in behavior. – Many people make a resolution to exercise more regularly at the start of the new year.
