Motor Coordination Problems (Developmental CoordinationDisorder-DCD) deal with a relatively recent problem that affects around 5-8% of the child population. It affects children who do not present any apparent cognitive deficit, but who show a deficient motor development for their age, with limitations of coordination and difficulties for the accomplishment of daily activities. DCD often coexists with other diseases. Therefore, this PhD presents a systematic review of the most relevant scientific literature analyzing the comorbidity of these difficulties with the Attention Deficit Disorder and Hyperactivity (ADHD). In addition, an empirical phase has been carried out in which the motor competence and psychosocial profile of a sample of students with ADHD have been evaluated and compared to their peers with typical development (TD) in the school context, particularly in Physical Education classes. Also, the experiences of the effects of a three-month Physical Education intervention on the levels of motor competence of a group of students with ADHD, compared with their peers with TD, on their psychological characteristics have been confirmed. and social implications in the style of participation and social interaction, the achievement motivation for learning and healthy active behaviors towards the practice of physical activity. Likewise, the perceptions of the Physical Education teachers on the levels of motor competence of their students with ADHD were compared with their peers with TD, as well as the effects that the aforementioned educational intervention that they had. The results have highlighted the differences present in certain psychological characteristics, among students with ADHD and their peers with TD. Moreover, the Physical Education intervention had XII positive effects on the motor competence of the two groups evaluated and on some of their psychological aspect.The importance of an early intervention in children diagnosed as DCD + ADHD is evident when analyzing the motor and attentional difficulties that hinder the normal development of their daily life (school, sport, relationships), which can be the cause of collateral problems.
