New research finds that even a small amount of exercise can help adults manage symptoms associated with attention deficit hyperactivity disorder (ADHD).
University of Georgia researchers found a single bout of exercise has psychological benefits for adults with these elevated ADHD symptoms.
Health providers have discovered that about six percent of American adults report symptoms consistent with ADHD. Common characteristics may include anxiety, depression, low energy, and suppressed motivation — factors that may lead to poor performance at work or school and also increased traffic accidents.
The study appears in the journal Medicine and Science in Sports and Exercise.
“Exercise is already known as a stress reducer and mood booster, so it really has the potential to help those suffering with ADHD symptoms,” said the study’s senior author Patrick O’Connor, professor in the University of Georgia College of Education’s kinesiology department.
“And while prescription drugs can be used to treat these symptoms, there’s an increased risk of abuse or dependence and negative side effects. Those risks don’t exist with exercise.”
The study tested 32 young men with elevated ADHD symptoms who cycled at a moderate intensity for 20 minutes on one day, and on another day sat and rested for 20 minutes as a control condition.
The participants were asked to perform a task requiring focus both before and after the different conditions, and researchers noted leg movement, mood, attention, and self-reported motivation to perform the task.
Researchers discovered that after the exercise, participants felt motivated to do the task; they also felt less confused and fatigued and instead felt more energetic.
Interestingly, leg movements and performance on the task did not change after the exercise — rather, the exercise helped the young men feel better about doing the task.
These findings are consistent with prior research that shows a single bout of exercise helps people feel more energetic, said O’Connor.
The results suggest that young men who have symptoms of ADHD can benefit psychologically from the short workouts, similar to the benefits enjoyed by typical adults who work out.
“The reduced feelings of confusion and increased motivation to perform a cognitive task suggest that other types of acute exercise also may benefit cognitive performance,” added study co-author Kathryn Fritz, a University of Georgia doctoral student who completed the study as part of her master’s thesis.
“We speculate that a different mode or duration or intensity of exercise, other than a boring cycle ride in a sterile lab, may show larger cognitive effects for those suffering from ADHD symptoms.”
