Can a 30-Minute Workout Boost Focus in People with ADHD? New Research Suggests So
A new study from Taiwan offers encouraging news for individuals with ADHD: just 30 minutes of aerobic exercise might be all it takes to enhance cognitive abilities. The research, led by neuroscientist Hsiao-I Kuo at National Taiwan University, sheds light on how activities like brisk walking, jogging, swimming, dancing, or cycling can positively impact the brain.
Previous research has shown that aerobic exercise tends to increase excitability in the cortex of individuals without ADHD, similar to the effects of stimulant medications like methylphenidate. However, people with ADHD generally have lower levels of intracortical inhibition – the brain’s ability to regulate and suppress neuronal activity – compared to the general population.
This new study looked into whether aerobic exercise could help normalize this inhibition in individuals with ADHD, potentially leading to improved focus.
The Study:
The researchers involved 26 unmedicated individuals with ADHD and 26 non-ADHD counterparts in a study that explored the effects of exercise on cognitive function. Participants completed two exercise sessions on stationary bikes, each lasting 30 minutes, interspersed with two control sessions.
During the exercise sessions, participants watched a nature documentary to minimize distraction.
Cognitive and Neurological Assessments:
Researchers conducted cognitive assessments before and after both exercise and control sessions. These assessments focused on inhibitory control and motor learning. They also used transcranial magnetic stimulation (TMS) to measure short-interval intracortical inhibition (SICI) and facilitation (ICF) – techniques that gauge the interaction strength between the motor cortex and muscles.
The Results:
The study found that individuals with ADHD experienced enhanced SICI after aerobic exercise, leading to improved performance in both inhibitory control and motor learning tasks.
While non-ADHD participants also showed improvements in motor learning after exercise, their SICI levels decreased. The exercise did not significantly affect their inhibitory control.
What This Means for ADHD Management:
“A single session of aerobic exercise temporarily boosts cortical inhibition in adults with ADHD, primarily through the GABAergic system,” the researchers noted. “This may enhance inhibitory control and motor learning in ADHD patients.”
While the findings are promising, they do not establish a causal link or determine the long-term impact of aerobic exercise on cognitive functions in ADHD. Further research is needed to explore these effects in more detail.
However, the study suggests that short, 30-minute aerobic exercise sessions could offer cognitive benefits for some individuals with ADHD in the short term. This could be a valuable addition to existing ADHD management strategies.
