How does sport affect the brain? Every time the heart speeds up during exercise, the brain starts functioning differently, with increased performance. Physical activity stimulates neurogenesis by triggering the growth of new neurons. So every step, kick against the ball or tug on the bike causes a cascade of biochemical reactions that feed brain cells and increase their interaction. These are proven scientific facts.
For years, scientists have studied how sport helps cognitive development and the results are impressive. Sport not only improves physical fitness but also helps develop qualities such as memory, concentration and learning ability. Regular exercise can therefore literally ‘pump up’ the intellect.
Physical activity and the brain: how and what is affected by sport
Physical exercise has a much more powerful effect on the brain than you might think. When the body gets moving, the brain responds by producing a number of beneficial chemicals, such as endorphins and neurotrophins. These substances are not only responsible for a good mood, but also greatly improve cognitive function.
How does sport affect the brain? During exercise, blood actively supplies the brain with oxygen, which in turn improves attention and concentration. Studies show that regular exercise increases the volume of the hippocampus, the part of the brain responsible for learning and memory.
For example, scientists at the University of Illinois found that 30 minutes of cardiovascular exercise leads to a 10-15% increase in activity in the hippocampus. This effect is due to improved blood circulation and increased oxygen supply to brain cells, which stimulates neurogenesis and strengthens connections between neurons. Physical activity therefore has a significant effect on improving long-term memory, the ability to absorb new information and improves overall learning ability.
How sport affects the brain: improving memory and learning ability
Sport is not just about muscles, but also about improving memory. Scientific evidence confirms that exercise strengthens connections between neurons, which has a positive effect on remembering information. Regular exercise improves brain activity and starts to work together: it increases neuroplasticity, data processing speed and the ability to multitask.
An example is yoga. Meditative exercises stimulate the brain’s prefrontal cortex, improving memory and attention. In addition, research from Harvard Medical School has shown that people who exercise regularly improve their memory by 20% on average. This is due to better blood flow and increased activity of the hippocampus.
Physical exercise, such as running or swimming, helps to absorb new information faster and more efficiently. Scholars and students who participate in sports do better in exams because their brains are used to working under conditions of increased activity and stress.
Sports that develop the brain
Not all sports are equally good for the brain. Some have particularly powerful effects on cognitive function:
- Running: stimulates the production of neurotrophins, which promote the growth of new cells and help the brain cope better with stress. Running also improves blood circulation and increases levels of endorphins and serotonin, which are responsible for good mood and optimal cognitive performance. Studies show that regular running increases grey matter volume, which is directly linked to better memory and faster decision-making.
- Yoga: improves concentration and reduces anxiety levels by activating the parasympathetic nervous system. The breathing exercises used in yoga help oxygenate the brain and reduce cortisol (stress hormone) levels. This improves the functioning of the prefrontal cortex, which is responsible for planning, decision-making and controlling emotions. Yoga also improves flexibility and balance, strengthening neural connections related to movement coordination.
- Team sports: develop not only physical skills, but also social skills and quick decision-making through interaction with other players. Basketball, football or volleyball stimulate brain activity because you have to make instant decisions and anticipate the team’s actions. Team sports also increase levels of oxytocin, a hormone that promotes trust and interaction with others, which has a positive effect on the development of social skills and cognitive flexibility.
These sports affect whole-brain development as they involve physical activity, mental tasks and social interactions.
Scientific research: how sport affects the brain
Science has long confirmed that sport has beneficial effects on the brain. One of the most famous studies was conducted in Finland, where 2,000 people aged between 40 and 65 participated in a study on the effects of exercise on cognitive function. The results showed that those who were physically active at least three times a week had 30% better memory and attention scores compared to those with sedentary lifestyles.
As another example, a study at Stanford University found that people who regularly engaged in aerobic exercise had 5 per cent more grey matter in the brain over a six-month period. The evidence confirms that exercise has a direct impact on cognitive health.
The athletic path to intelligence
How does sport affect the brain? They work faster, more flexibly and efficiently. All these benefits open a new avenue for personal development and self-improvement. If you start exercising today, you are guaranteed not only good health, but also a clear mind for years to come. Everyone has the chance to strengthen their brain: just start moving and working on yourself.
