IntroductionVery preterm birth and attention-deficit hyperactivity disorder (ADHD) are associated with impairments in response inhibition that often persist beyond childhood. Athletes skilled in martial arts show a neurocognitive profile that is associated with an improved inhibition processing stream, suggesting that engagement in this kind of sport has the potential to reduce impairments in this cognitive function. We investigated the behavioral and neurocognitive effects of judo training on response inhibition in children born very preterm and children with ADHD by a combined analysis of two randomized controlled trials.MethodsIn both the CHIPMANC (n = 65) and JETPAC (n = 63) studies, participants were randomly allocated to a waitlist or a 12-wk judo training program in a 1:1 ratio. At pretest and posttest, participants completed a Go/NoGo task, the Movement Assessment Battery for Children-2 and a physical work capacity test on a bicycle ergometer. During the cognitive task, event-related potentials (N2, P3a, P3b) were recorded via electroencephalography.ResultsThe effects of the judo training were moderated by the study group. In contrast to children with ADHD (JETPAC), judo training reduced the commission error rate on the Go/NoGo task and increased the P3a amplitude in children born very preterm (CHIPMANC). No treatment effects were found for N2, P3b and physical fitness outcomes.ConclusionsThe neurodevelopmental condition influences the cognitive benefits of judo training. Whereas judo may be ineffective in children with ADHD, children born very preterm can expect improved response inhibition due to a more effective engagement of focal attention to resolve the task-related response conflict.
