Exploratory Study: The Impact of Online Coordinative Exercise in a Small Latinx Youth Sample

<b>Background/Objectives:</b> The effects of online physical activity (PA) interventions on executive function (EF) and Attention-Deficit Hyperactivity Disorder (ADHD) symptoms are promising; nonetheless, their benefits for Latinx youth remain unclear. <b>Methods:</b> This study explores levels of adherence, cognitive and behavioral outcomes and acceptability of an online PA intervention, Zing Performance, among a Latinx youth sample; only a few of the participants completed their condition (<i>n</i> = 6). <b>Results</b>: There was wide variability in adherence levels at mid-treatment (<i>n</i> = 5) and high-level adherence at post-treatment (<i>n</i> = 2). A Mann-Whitney test yielded a statistically significant (<i>p</i> = 0.004) improvement in the treatment group's inattention symptoms at mid-treatment (<i>n</i> = 5), compared to the Waitlist Control; (WLC; <i>n</i> = 6). EF and hyperactivity/impulsivity were not significantly different. Further, pre-, mid- and post-participant trajectory data revealed that one participant benefited significantly from treatment, one participant demonstrated little to no response to treatment, and most of the WLC participants remained in the severity ranges throughout the 12 weeks. The parents of the two children who completed treatment reported high levels of acceptability informally and on the quantitative measure. <b>Conclusions:</b> Exploratory findings support further investigation of Zing among Latinx families with cultural consideration to study procedures. The lessons learned from this study are valuable for future research procedures and interventions with this marginalized population.
