ADHD and Exercise Science: Natural Dopamine and BDNF
Neurotropic effects of physical activity on the brain and its role in alleviating ADHD symptoms.
What Changes in the Brain?
Physical exercise is not just a sports activity for the ADHD brain; it is a neurochemical intervention. During and immediately after exercise, the following changes are observed in the brain:
1. Neurotransmitter Increase: Exercise naturally increases dopamine and norepinephrine levels, which are the targets of ADHD medications, thereby sharpening attention.
2. BDNF Release: Often called "brain fertilizer," the BDNF protein protects neuron health and allows new learning pathways to open.
3. Inhibition Control: Research (PubMed) shows that even a single session of intense exercise provides immediate improvement in impulse control (the ability to press the brakes).

ADHD-Friendly Exercise Types
All movement is beneficial, but the ADHD brain benefits more from certain types:
Complex Sports: Sports that require instant decision-making and balance, like tennis, basketball, or martial arts, also activate the "cerebellum" region of the brain, more strongly stimulating attention networks.
Aerobic Activity: Brisk walking or cycling that raises the heart rate clears the "foggy" air in the brain and provides mental clarity.
The Nature Effect (Green Time): Studies show that activities done in nature alleviate ADHD symptoms 30% more compared to those done in urban settings.

Creating a Sustainable Routine
For ADHD individuals, starting a routine is easy, but maintaining it is difficult. In light of scientific data, the following strategies are recommended:
Timing: If you struggle to focus in the morning, doing a 20-minute exercise before starting work is the best way to start your "mental engine."
Fun Factor: Don't forget your brain's need for dopamine. Choose activities that excite you or contain a game element rather than a sport you find boring.
Small Steps: Doing 10 minutes of jumping or walking every day is more valuable for consistency than a 1-hour intense workout.
