Abstract

This study investigated whether neuro-exergaming with an interactive physical and cognitive exercise system (iPACES), might alleviate symptoms in college students with symptoms of Attention Deficit Hyperactivity Disorder (sxADHD). It was hypothesized that challenges with attention and executive function, often experienced by those with sxADHD, would improve after an acute bout of pedal-n-play exercise. College students (n = 33; 18 with sxADHD) participated in a 20 min single bout of exercise, pedaling along a virtual pathway (tour), while steering the tablet. Mental exercise included a working memory (focus) task to steer toward assigned locations along the path. An exploratory experimental condition was also embedded in the basic pre/post design, wherein half of the students were randomly assigned collectibles (coins) in the pathway. Cognition was assessed (e.g., paper and digital Stroop, Trails, Digit Span) before and after the acute bout of exercise. Paired t-tests revealed significant improvements in executive function on both paper and electronic Stroop tasks for those with sxADHD, while significant change was also seen on Trails and Digit Span for normative students. Surprisingly, those with sxADHD, assigned to the experimental “multi-tasking” collectible (coin) challenge, performed significantly better on tests of executive functioning than normative peers, who improved more without coins. It is hypothesized that the collectible challenge provided additional mental stimulation or reward needed to increase attentional focus for those with sxADHD, leading to improved performance, post-exercise. While the findings of this study are preliminary, additional research can further explore possible designs for combined, interactive mental and physical exercise challenges, as well as further possible synergistic or differential neural activation, in order to maximize outcomes from the same amount of time exercising. Additionally, future research could examine longer-term use of neuro-exergaming, through a clinical trial, as an alternative to, or in conjunction with, medication for sxADHD treatment and symptom relief.
