Attention deficit hyperactivity disorder (ADHD) is the most prevalent neurodevelopment disorder in childhood affecting 11% of school-aged children 1 and associated with wide-ranging impairments, 2 including academic underachievement, social problems, substance abuse, and negative health outcomes

Attention deficit hyperactivity disorder (ADHD) and other learning difficulties (LD) are neurocognitive disorders that can occur individually or concurrently. 1 Those who suffer from LD commonly experience dyslexia or dyscalculia. 1 , 2 ADHD has a prevalence rate of 5.3% worldwide and is the most

Physical activity experiences of 12 age-matched boys with and without attention-deficit hyperactivity disorder (ADHD) were explored by converging information from Test of Gross Motor Development-2 assessments and semistructured interviews. The knowledge-based approach and the inhibitory model of executive functions, a combined theoretical lens, enabled the description of similarities and differences in experiences that emerged during interviews. Skill assessments indicated boys with ADHD were not as proficient movers as their peers without ADHD. Thematic analysis revealed that boys with ADHD reported playing with friends, paid little attention to detail, possessed superficial knowledge about movement skills, and expressed many negative feelings about physical activity. Task-specific interventions and a wider range of mixed methods research are recommended for future research studies in ADHD.

Objective:

The purpose of the current study was to examine the association between structured physical activity, specifically physical education, and symptoms of Attention Deficit Hyperactivity Disorder (ADHD). Physical activity may be associated with lower levels of symptoms of ADHD and this rationale provided the impetus for the current study.

Methods:

A community-based, nationally representative sample of children from the Early Childhood Longitudinal Study, Kindergarten cohort (ECLS-K) was used. Structural equation modeling was used to examine the association of physical activity with symptoms of Attention Deficit Hyperactivity Disorder. Two random subsamples were drawn for the purposes of cross-validation of our model. Statistics reflecting model ft are reported.

Results:

With a standardized path coefficient value of –.23, findings from the current study indicate a significant, inverse association between physical education, as a structured form of physical activity, with the symptoms of Attention Deficit Hyperactivity Disorder in children.

Conclusions:

Using a community-based, nationally representative sample of children aged 5 to 7 years old from the United States, the results of the current study suggest that physical education, as a structured form of physical activity, may be considered as associated with lower levels of symptoms of ADHD across time.

The purpose was to investigate central and peripheral processing mechanisms through the use of electromyography (EMG) to determine differences between the performance of children with and without ADHD on a lower extremity choice response time task. Sixteen children with ADHD were tested on and off medication along with 19 children without ADHD. For premotor time, the comparison group performed significantly faster than children with ADHD. The longer latencies exhibited in central processing of children with ADHD were related to midline crossing inhibition (MCI). Medication improved the speed of processing for children with ADHD, but did not negate MCI.

The prevalence of Attention Deficit Hyperactivity Disorder (ADHD) is between 2%-10% of children (Center for Disease Control, 2003). Participation in organized sports is beneficial to children with ADHD by increasing self-esteem, self-efficacy, peer acceptance, and social skills (Armstrong & Drabman, 2004; Bagwell, Brooke, Pelham, and Hoza, 2001). Little research exists as to preparation for youth sport coaches with regard to coaching athletes with ADHD. The study’s purpose was to investigate coaches’ efficacy beliefs for coaching athletes with ADHD. Two hundred nineteen volunteer coaches completed a questionnaire designed to measure their beliefs. The results showed that overall coaches reported fairly high feelings of efficacy for working with athletes with ADHD. However, results also indicated that coaches reporting experience with athletes with ADHD reported higher efficacy for coaching athletes with ADHD than their less experienced peers. Implications for coaching education include the incorporation of behavior management techniques into course content and the creation of ADHD resources such as weblinks and pamphlets.

The effect of stimulant medication use by children with attention deficit/hyper-activity disorder (ADHD) on the rating of perceived exertion (RPE)—heart rate (HR) relationship was examined. Children with ADHD (n = 20; 11.3 ± 1.8 yrs) and children without ADHD (n = 25; 11.2 ± 2.1 yrs) were studied. Children with ADHD were examined while on their usual dose of medication on the day of study. HR and RPE, using the OMNI RPE scale, were assessed during a graded exercise to peak voluntary effort. The RPE-HR relationship was determined individually and the intercept and slope responses were compared between groups. The intercept was 132.4 ± 19.5 bpm for children with ADHD and 120.6 ± 15.7 bpm for children without ADHD. The slope was 7.3 ± 1.9 bpm/RPE for the children with ADHD and 8.1 ± 1.6 bpm/RPE for the children without ADHD. For the group with ADHD the intercept and slope values fell outside of the 95% CI observed in the control group. The altered relationship between RPE and HR with stimulant medication use in children with ADHD has practical implications with respect to the use of HR and RPE to monitor exercise intensity.

The purpose of this study was to explore youth sport experiences of individuals with attention deficit/hyperactivity disorder (ADHD). Participants were 6 males (mean age = 22.7 yr) with ADHD who had played 3 or more seasons in team sports during adolescence. Following interpretive phenomenological analysis methodology, each participant completed 2 semistructured interviews. Findings showed that symptoms of ADHD hampered participants’ experiences and led to negative interpersonal and performance-related consequences. On the other hand, participants reported social and stress/energy-release benefits arising from their experiences in sport. Their experiences were therefore complex, and some findings relating to social interactions appeared contradictory (e.g., negative interpersonal experiences vs. social benefits). Supportive coaches, understanding teammates, and personal coping strategies were key factors that enabled participants to realize benefits and, to some degree, mitigate negative consequences associated with their participation in sport.

The purpose of the current study was to examine the relationship between motor ability and response inhibition using behavioral and electrophysiological indices in children with ADHD. A total of 32 participants were recruited and underwent a motor ability assessment by administering the Basic Motor Ability Test-Revised (BMAT) as well as the Go/No-Go task and event-related potential (ERP) measurements at the same time. The results indicated that the BMAT scores were positively associated with the behavioral and ERP measures. Specifically, the BMAT average score was associated with a faster reaction time and higher accuracy, whereas higher BMAT subset scores predicted a shorter P3 latency in the Go condition. Although the association between the BMAT average score and the No-Go accuracy was limited, higher BMAT average and subset scores predicted a shorter N2 and P3 latency and a larger P3 amplitude in the No-Go condition. These findings suggest that motor abilities may play roles that benefit the cognitive performance of ADHD children.
