Exercise, even a small amount, can help alleviate symptoms of attention-deficit hyperactivity disorder (ADHD) in adults, say researchers. ADHD symptoms can lead to depression, low energy and motivation, poor performance at work or school and also increased traffic accidents. A single bout of exercise has psychological benefits for adults with these elevated ADHD symptoms, which lead to anxiety, the findings showed. “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 at the University of Georgia, USA.
“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,” O’Connor said. The study tested 32 young men with elevated ADHD symptoms who cycled at a moderate intensity for 20 minutes in 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. As a result, researchers found that it was only after the exercise when the participants felt motivated to do the task. They also felt less confused and fatigued and instead felt more energetic. The study was published in the journal Medicine and Science in Sports and Exercise. 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.
