Motor competence moderates relationship between moderate to vigorous physical activity and resting EEG in children with ADHD

BackgroundChildren with ADHD display abnormal electroencephalographic (EEG) activity, in particular an elevated theta to beta ratio (TBR) during the resting state. AimsTo assess whether the motor competence (MC) and moderate–to-vigorous physical activity (MVPA) were associated with TBR, and whether MC moderated the relationship between MVPA and TBR. MethodsData from a total of 73 children with ADHD (69 boys and 4 girls, mean age = 9.92 years, SD = 1.56 years) were analyzed. EEG readings were taken as participants rested with their eyes open. MC was assessed using the Movement ABC-2 measure, and MVPA was evaluated using an ActiGraph accelerometer. ResultsMC was negatively associated with TBR, and an interaction between MVPA and MC on TBR was observed. It was found that there was a negative correlation between MVPA and TBR in those with high MC, whereas the relationship was positive in those with low MC. Conclusions and implicationsThe current study found that increased MC was associated with less deviant cortical activity in the resting state, as measured by TBR, and that MC moderated the relationship between MVPA and TBR after controlling for age. It highlights the importance of increasing motor competence within physical activity to improve cortical functioning of children with ADHD.

The Influence of Motor Competence on Adolescent Identity Health: A Mixed Method Study

ABSTRACTOur identity develops with age, and many impacting factors will determine whether it is healthy or unhealthy. A particularly fragile phase of identity development occurs during adolescence when level of motor competence may be influential, yet is rarely considered. Purpose: The purpose of this study was to examine male and female adolescent’s perceptions towards their motor competence and identity development. In-depth information was also collected to understand what factors are important towards identity development during adolescence. Method: An explanatory sequential mixed methods study was used to examine the extent motor competence influenced the health of an adolescent’s identity. A sample of 160 adolescents (male n = 103, female n = 57, Mage = 14.45 SD = .75) completed the Adolescent Motor Competence Questionnaire (AMCQ) and the Assessment of Identity Development in Adolescence (AIDA). The AMCQ scores were used to group the participants into high (HMC = > 83) and low (LMC = < 83) motor competence. Results: More females had less-healthy identities than males and those with LMC had less-healthy identities than those with HMC. Subsamples of 17 participants were interviewed in order to explain these results. The most at risk group, females with LMC, identified negative peer comparisons, poor social support and higher stress levels to achieve academic performance as key challenges. Conclusions. Well-designed support services for those with LMC, especially for the females should incorporate activities to develop individual competency and close friendships.

The longitudinal relationship between motor competence and measures of fatness and fitness from childhood into adolescence

ObjectivesTo examine longitudinal (seven years) relationships among cardiorespiratory fitness (VO2peak), body fatness, and motor competence. MethodData were collected as part of the Copenhagen School Child Intervention Study (CoSCIS). Body fatness was assessed by the sum of four skinfolds. VO2peak was measured directly in a continuous running protocol. Motor competence was assessed using the Körperkoordinationtest für Kinder. This study used multilevel linear mixed models to evaluate the reciprocal longitudinal association between body fatness, VO2peak, and motor competence. All regressions were stratified by sex and adjusted by intervention and pubertal status. All variable coefficients were standardized. ResultsA reciprocal relationship was observed between children's motor competence with body fatness and VO2peak at the seven‐year follow‐up (6–13 years of age). Children with higher motor competence at baseline had a lower risk of having higher body fatness (βboys=−0.45, 95% CI: −0.52 to −0.38; βgirls=−0.35, 95% CI: −0.42 to −0.28) and higher VO2peak (βboys=0.34, 95% CI: 0.27–0.40; βgirls=0.27, 95% CI: 0.20–0.33) during childhood. Alternatively, higher body fatness or lower levels of VO2peak at baseline were associated with lower motor competence during childhood. ConclusionsThese data suggest motor competence, body fatness, and VO2peak demonstrate reciprocal relationships across childhood (6–13 years of age). Interventions addressing motor competence, cardiorespiratory fitness, and body fatness in early childhood are recommended, as intervention effects are likely to be enhanced because of the mutual reciprocal associations between these three variables.

Environmental Correlates of Motor Competence in Children-The Skilled Kids Study.

Environment, physical activity (PA) and motor development are tightly interwoven during childhood. We examined the associations of environmental factors with motor competence (MC) in children. Children (N = 945, 50.1% boys, age = 3–7 years, mean = 5.4 years) from 37 childcare centres in the Southern (n = 17), Central (n = 13) and Northern Finland (n = 7) participated. The environmental factors comprised the geographical location (Southern, Central and Northern Finland) and residential density (metropolitan area, city, rural area and countryside) of the childcare centres’ based on postal codes and the national population density registry. MC was measured using the Test of Gross Motor Development (TGMD)-3, as well as by quantifying time spent outdoors and participation in organised sports via parental questionnaire. It was found that children from the countryside had better MC and spent most time outdoors, while children from the metropolitan area most frequently engaged in organised sports. Gender comparisons revealed that girls outperformed boys in locomotor skills, while boys were better in object control skills, had higher TGMD-3 score and spent more time outdoors. Time spent outdoors and participation in organised sports were associated positively with MC, but not in children from the countryside. In conclusion, higher population density was associated with lower MC and less time spent outdoors. The findings suggest that versatile outdoor environments may support motor development through PA.

Investigating Motor Competence in Association with Sedentary Behavior and Physical Activity in 7- to 11-Year-Old Children.

Children’s motor competence (MC) has declined in the past decades, while sedentary behavior (SB) has increased. This study examined the association between MC and physical activity (PA) levels among primary schoolchildren. Demographics, body height and weight, MC (Athletic Skills Track), and PA levels (ActiGraph, GT3X+) were assessed among 595 children (291 boys, mean age = 9.1 years, SD = 1.1). MC was standardized into five categories: from very low to very high. PA levels were classified into SB, light PA (LPA), and moderate-to-vigorous PA (MVPA). Mixed-model analyses were conducted with PA levels as dependent variables and MC as the independent variable, while adjusting for age, gender, and body mass index (BMI) z-score on the individual level. A negative association between MC and SB and a positive association between MC and MVPA were found. The strength of both associations increased as children expressed lower or higher levels of MC. MC is an important correlate of both SB and MVPA, particularly for children with very high or low MC. Developing and improving children’s MC may contribute to spending less time in SB and more time in MVPA, particularly for high-risk groups, i.e., children with low MC. Moreover, addressing MC development and PA promotion simultaneously might create positive feedback loops for both children’s MC and PA levels.

Difference in physical fitness in children with initially high and low gross motor competence: A ten-year follow-up study

The aim of the study was to investigate the difference in relative physical fitness between children with initially high and low gross motor competence in a ten-year prospective study. A sample of 49 children from a local primary school was tested on gross motor competence and physical fitness in 1st grade (5/6 years old). The children were tested again in 2nd (motor competence only), 7th, and 10th grade (15/16 years old). The sample was divided into two groups; initially high and low gross motor competence, according to score (median-split) on the Körperkoordinationstest für Kinder-test battery in 1st grade. Results suggested that the initially high gross motor competence-group performed significantly better on a multidimensional physical fitness test, compared to the initially low gross motor competence-group at all time-points. There were also statistically significant differences between the groups in gross motor competence in 7th and 10th grade, with the initially high gross motor competence-group scoring most favorable. The findings from the present study highlight the importance of identifying and supporting young individuals with low gross motor competence, to prevent low levels of physical fitness in the future.

Suboptimal bone status for adolescents with low motor competence and developmental coordination disorder—It’s sex specific

BackgroundAustralian adolescents with low motor competence (LMC) have higher fracture rates and poorer bone health compared to European normative data, but currently no normative data exists for Australians. AimsTo examine whether there were bone health differences in Australian adolescents with LMC or Developmental Coordination Disorder (DCD) when compared to typically developing age-matched Australian adolescents. Methods and ProceduresAustralian adolescents aged 12–18 years with LMC/DCD (n = 39; male = 27; female = 12) and an Australian comparison sample (n = 188; boys = 101; girls = 87) undertook radial and tibial peripheral Quantitative Computed Tomography (pQCT) scans. Stress Strain Index (SSI (mm3)), Total Bone Area (TBA (mm2)), Muscle Density (MuD [mgcm3]), Muscle Area (MuA [cm2]), Subcutaneous Fat Area (ScFA [cm2]), Cortical Density (CoD [mgcm3]), Cortical Area (CoD [mm2]), cortical concentric ring volumetric densities, Functional Muscle Bone Unit Index (FMBU: (SSI/bone length)) and Robustness Index (SSI/bone length^3), group and sex differences were examined. Outcome and ResultsThe main finding was a significant sex-x-group interaction for Tibial FMBU (p = .021), Radial MuD (p = .036), and radial ScFA (p = .002). Boys with LMC/DCD had lower tibial FMBU scores, radial MuD and higher ScFA than the typically developing age-matched sample. Conclusion and ImplicationsComparisons of bone measures with Australian comparative data are similar to European findings however sex differences were found in the present study. Australian adolescent boys with LMC/DCD had less robust bones compared to their well-coordinated Australian peers, whereas there were no differences between groups for girls. These differences may be due to lower levels of habitual weight–bearing physical activity, which may be more distinct in adolescent boys with LMC/DCD compared to girls.

Time for change: Fitness and strength can be improved and sustained in adolescents with low motor competence

BackgroundThere are few exercise interventions focused on adolescents with low motor competence and most interventions are short with little follow up and engagement over time. Methods and proceduresFifty-eight adolescents with low motor competence (39 males, Mean Age = 13.6, SD = 1.4 years) attended an exercise clinic twice a week for each 13 week program. Two programs ran each year, and participants attended for as long as they felt progress was made or they turned 18 years of age. Performance on the Multistage Fitness Test (MSFT), Curl-ups, Grip Strength, 1RM Leg press and Chest Press, Vertical Jump and Standing Broad Jump (SBJ) were recorded pre and post each program for up to six years.Linear Mixed Modelling (LMM) determined changes in fitness measures over time whilst adjusting for gender, age and Neuromuscular Developmental Index (McCarron, 1997). ResultsAll fitness measures increased, and specifically four of the seven fitness outcomes showed significant improvement over time (MSFT,p = 0.011; curl-ups, p < 0.001, grip strength p = 0.003, and SBJ p = 0.006). ConclusionAn individually tailored regular exercise program in a supportive environment can achieve exercise adherence and sustainable improvements in fitness outcomes for adolescents with low motor competence. Future research should consider the addition of a comparison LMC control group to increase understanding of the intervention effect.

The Relationship Between Motor Skills, Psychosocial Adjustment and Peer Victimization in School-Aged Children

The aim of this study was to investigate the relationships between childrens’ motor competence, psychosocial adjustment, peer victimization, physical activity participation and obesity. Using the Elaborated Environmental Stress Hypothesis as the framework, we hypothesized that multiple stressors influence children with poor motor competence and that the pathway from motor competence to psychosocial maladjustment is more complex than initially thought. A sample of child-parent dyads (n = 51; children ages 7 to 10 years), were recruited from two educational institutions in Sudbury, Ontario. Child participants completed self-report measures on peer victimization, depression symptoms, loneliness and anxiety symptoms across five dimensions (social phobia, obsessive-compulsive disorder, separation anxiety, panic disorder and generalized anxiety). Child participants also completed the Test of Gross Motor Development-3. Parent participants completed a sociodemographic questionnaire and a questionnaire on their child’s levels of participation in physical activity. For boys, Pearson product-moment correlations revealed that lower motor competence was significantly related to depressive symptoms, social phobia, separation anxiety symptoms, loneliness and peer victimization. For girls, lower motor competence was significantly related to separation anxiety symptoms and loneliness. No correlations were found between motor competence, weight status and physical activity participation. Findings are consistent with previous literature. These findings suggest that (1) boys are more psychosocially affected and victimized than girls when measured against motor competence and, (2) children are experiencing these issues as early as age 7, which is a time when children are starting to build social relationships. More research is required strengthen these findings.

\u201cNot just another Wii training\u201d: a graded Wii protocol to increase physical fitness in adolescent girls with probable developmental coordination disorder-a pilot study

BackgroundAdolescents with low motor competence participate less in physical activity and tend to exhibit decreased physical fitness compared to their peers with high motor competence. It is therefore essential to identify new methods of enhancing physical fitness in this population. Active video games (AVG) have been shown to improve motor performance, yet investigations of its impact on physical fitness are limited. The objective of this study was to examine the impact of the graded Wii protocol in adolescent girls with probable Developmental Coordination Disorder (p-DCD).MethodsA single-group pre-post design was conducted to assess the impact of a newly developed Wii protocol in adolescent girls attending school in a low income community of Cape Town, South Africa. Sixteen participants (aged 13-16 years) with p-DCD (≤16th percentile on the MABC-2 test) were recruited. Participants received 45 min Wii training for 14 weeks. Outcome measures included the six-minute walk distance and repeated sprint ability. Information on heart rate, enjoyment and perceived exertion ratings were also collected.ResultsSignificant improvements in aerobic and anaerobic fitness were observed. The participants reported high enjoyment scores and low perceived exertion ratings. The graded Wii protocol was easily adaptable and required little resources (space, equipment and expertise) to administer.ConclusionsThe findings provide preliminary evidence to support the use of the graded Wii protocol for promoting physical fitness in adolescent girls with p-DCD. Further studies are needed to confirm these results and to validate the clinical efficacy of the protocol in a larger sample with a more robust design.

The Role of Perceived and Actual Motor Competency on Children’s Physical Activity and Cardiorespiratory Fitness During Middle Childhood

Purpose:Guided by Stodden et al.’s (2008) conceptual model, the purpose of this study was to examine the associations among perceived competence, actual motor competence (MC), physical activity (PA), and cardiorespiratory fitness in elementary children. The group differences were also investigated as a function of MC levels.Methods:A correlational research design was used in this study. There were 262 children (Mage = 10.87, SD = .77) recruited from three schools in the southern U.S. Students’ MC was objectively measured based on a process-oriented assessment (PE Metrics, NASPE, 2010). Students self-reported perceived competence and leisure-time PA. Then, the Progressive Aerobic Cardiovascular Endurance Run (PACER) and pedometers were used to measure students’ cardiorespiratory fitness and in-class PA, respectively.Results:The structural equation modeling analysis supported the significant indirect effect of the MC on cardiorespiratory fitness and PA through perceived competence. The MANCOVA yielded a significant main effect for MC groups after controlling for sex [Wilks’s Lambda = .838, F = 12.15 (4, 251), p &lt; .001, η2 = .16]. Regardless of sex, children with low MC demonstrated lower perceived competence, PA, and cardiorespiratory fitness compared with children with higher MC (p &lt; .001).Discussion:Development of students’ competence beliefs in PE and certain movement patterns should be emphasized, especially during middle childhood. High quality PE programs must be aligned with national standards, with particular attention to enhancing skill acquisition (standard 1) and PE-motivation (i.e., perceived competence; standard 5).

Link between Motor Competence and Health Related Fitness in Children and Adolescents.

This study examined motor competence (MC) behavior in 6- to 14-year-old children, and investigated the differences in health-related fitness (HRF) between high and low MC groups, according to sex and age. A sample of 564 children (288 males) participated in this study, divided into three age groups (6–8 years; 9–11 years; 12–14 years). Total MC and its three components (stability, locomotor, and manipulative) were assessed with a quantitative instrument. HRF was evaluated using a maximal multistage 20-m shuttle-run test and the handgrip test. Participants were divided into tertiles according to their MC level and high and low MC groups were analyzed. Overall, MC increased across age groups for both sexes, but boys presented better results than girls. The high MC group outperformed their low MC peers in all HRF variables, independent of their age group. Although cardiovascular fitness increased with age for both the high and low MC groups, the differences between these groups were greater in older children compared to younger children, within the study age range. The findings suggest that MC interventions should be considered as an important strategy to enhance HRF, and girls at a young age should be a priority target.

Identifying a motor proficiency barrier for meeting physical activity guidelines in children.

This study examined the existence of a threshold level (proficiency barrier) of actual motor competence (MC) below which a child is not likely to attain 60min of moderate-to-vigorous physical activity (MVPA) per day. A cross-sectional study. Actual MC was assessed in 326 children (48.5% boys; age=9.50±1.24years) using the Test of Gross Motor Development-2; MVPA was measured with ActiGraph GT3X+accelerometers. Perceived MC, included as a potential mediating variable, was assessed with the Self-Perception Profile for Children. Binary logistic (mediation) regression analyses controlling for sex and a chi-squared test were used to gain insight into the relationship between (the levels of) actual MC and the percentage of children meeting the MVPA guideline. Actual MC significantly predicted the percentage of children meeting the guideline (B=.03, SE=.01, p<.001), even when controlling for sex. Perceived MC did not mediate this relationship. Children with high actual MC (65-100 percentile) were 2.46 (p=.003) times more likely to meet the guideline than children with low actual MC (0-27 percentile). The present study demonstrates the potential impact of low MC on children's MVPA levels and suggests evidence for the existence of a proficiency barrier for meeting MVPA guidelines. Almost 90% of the children whose actual MC is below the 'average' threshold do not meet the MVPA guideline. As more children with higher levels of actual MC meet the guideline than their less competent peers, it is crucial to provide opportunities to sufficiently develop children's actual MC.

Gait and gross motor improvements in a two-year-old child with arthrogryposis after hippotherapy intervention using a Norwegian Fjord

The aim of the study was to investigate the difference in relative physical fitness between children with initially high and low gross motor competence in a ten-year prospective study. A sample of 49 children from a local primary school was tested on gross motor competence and physical fitness in 1st grade (5/6 years old). The children were tested again in 2nd (motor competence only), 7th, and 10th grade (15/16 years old). The sample was divided into two groups; initially high and low gross motor competence, according to score (median-split) on the Körperkoordinationstest für Kinder-test battery in 1st grade. Results suggested that the initially high gross motor competence-group performed significantly better on a multidimensional physical fitness test, compared to the initially low gross motor competence-group at all time-points. There were also statistically significant differences between the groups in gross motor competence in 7th and 10th grade, with the initially high gross motor competence-group scoring most favorable. The findings from the present study highlight the importance of identifying and supporting young individuals with low gross motor competence, to prevent low levels of physical fitness in the future.

Comparison of motor competence levels on two assessments across childhood

ABSTRACTThis study compared performances and motor delay classifications for the Test of Gross Motor Development-2nd edition (TGMD-2) and the Körperkoordinationstest Für Kinder (KTK) in a sample of 424 healthy children (47% girls) between 5 and 10 years of age. Low-to-moderate correlations (r range = 0.34–0.52) were found between assessments across age. In general, both boys and girls demonstrated higher raw scores across age groups. However, percentile scores indicated younger children outperformed older children, denoting a normative percentile-based decrease in motor competence (MC) in the older age groups. In total, the TGMD-2 and KTK classified 39.4% and 18.4% children, respectively, as demonstrating very low MC (percentile ≤5). In conclusion, the TGMD-2 classified significantly more children with motor delays than the KTK and the differences between children’s motor skill classification levels by these assessments became greater as the age groups increased. Therefore, the TGMD-2 may demonstrate more susceptibility to sociocultural influences and be more influenced by cumulative motor experiences throughout childhood. Low-to-moderate correlations between assessments also suggest the TGMD-2 and KTK may measure different aspects of MC. As such, it may be important to use multiple assessments to comprehensively assess motor competence.

Comparison of health outcomes among children with different levels of motor competence

PurposeWhile evidence suggests that children with the developmental coordination disorder (DCD) have worse health outcomes than their typically developing peers, it remains unclear whether children with low motor competence but without DCD are also characterized by worse health outcomes than those with average motor competence. The main purpose of this study was to compare health outcomes between children with low motor competence without DCD and those with average motor competence.MethodsThe total of 127 children aged 12–14 years were recruited. Motor competence, physical activity, flexibility, and muscular strength/endurance were assessed with, respectively, the Körperkoordinationstest für Kinder, a validated self-administered questionnaire, sit-and-reach, and sit-up 60s tests. Skinfold thickness was measured to assess the children’s adiposity. Multivariate analysis of variance, Kruskal-Wallis, and Mann-Whitney tests were performed.ResultsChildren with average motor competence had lower body fat percentage and higher levels of physical activity and muscular strength/endurance than the groups with low (&lt;i&gt;p&lt;/i&gt; &lt; 0.05) and very low (&lt;i&gt;p&lt;/i&gt; &lt; 0.01) motor competence. Further, children with low motor competence had lower body fat percentage (&lt;i&gt;p&lt;/i&gt; &lt; 0.01) and higher levels of muscular strength/endurance (&lt;i&gt;p&lt;/i&gt; &lt; 0.01) than their peers with very low motor competence.ConclusionsOur findings suggest that children with low motor competence without DCD have worse health outcomes than their peers with average motor competence. We suggest that both the development of motor competence and improvement of health outcomes should be targeted during childhood and adolescence by health professionals.

Identifying profiles of actual and perceived motor competence among adolescents: associations with motivation, physical activity, and sports participation

ABSTRACTThe present study identified adolescents’ motor competence (MC)-based profiles (e.g., high actual and low perceived MC), and accordingly investigated differences in motivation for physical education (PE), physical activity (PA) levels, and sports participation between profiles by using regression analyses. Actual MC was measured with the Körperkoordinationstest für Kinder. Adolescents (n = 215; 66.0% boys; mean age = 13.64 ± .58 years) completed validated questionnaires to assess perceived MC, motivation for PE, PA-levels, and sports participation. Actual and perceived MC were only moderately correlated and cluster analyses identified four groups. Two groups of overestimators (low – overestimation, average – overestimation) were identified (51%), who particularly displayed better motivation for PE when compared to their peers who accurately estimated themselves (low – accurate, average – accurate). Moreover, adolescents with low actual MC, but high perceived MC were significantly more active than adolescents with low actual MC who accurately estimated themselves. Results pointed in the same direction for organised sports participation. Underestimators were not found in the current sample, which is positive as underestimation might negatively influence adolescents’ motivation to achieve and persist in PA and sports. In conclusion, results emphasise that developing perceived MC, especially among adolescents with low levels of actual MC, seems crucial to stimulate motivation for PE, and engagement in PA and sports.

PHYSICAL FITNESS, SELF-PERCEPTION AND PHYSICAL ACTIVITY IN CHILDREN WITH DIFFERENT MOTOR COMPETENCE

The aim of the study was to investigate if children at the age of 11 with total scores at or above 13.5 (lower motor competence) on Motor assessment Battery for Children (MABC) differ from children scoring below 13.5 (higher motor competence) in physical fitness, self-perception and physical activity. A total of 67 children completed the Test of Physical Fitness and Harter‟s Self-perception Profile for Children, and two questions concerning physical activity. Children with lower motor competence performed poorer on all fitness tasks, were less physically active and had lower perception of athletic competence and social acceptance, than the group with higher motor competence. These findings indicate that lower levels of motor competence may impact several health related variables in children. In this respect the importance of experience with the tasks measured are discussed. Additionally, the benefits of a mastery-oriented climate to promote physical activity in school, especially for children with lower motor competence, are emphasized.

Exercise can improve physical self perceptions in adolescents with low motor competence

Adolescents with low motor competence have diminished perceptions of their physical self and tend to avoid physical activities. This study examined the outcomes of an exercise intervention that focused on improving aerobic fitness, strength, and self-perceptions in the physical domain in adolescents with poor motor coordination. The sample included 35 adolescents with low motor competence, comprising boys (n=25) and girls (n=10) ranging in age from 13 to 17years, who attended two sessions per week in the 13week exercise intervention study (AMP it up). Physical self-perceptions were measured before and after the intervention using the Physical Self Perception Profile and Perceived Importance Profile. Significant improvements in perceived Physical Condition, Attractive Body and Physical Strength sub domain scores were identified between pre and post-test. Adjusting for age, gender, BMI and attendance, regression analyses revealed that Attractive Body was the strongest predictor of Physical Self Worth at pre-test, joined by Physical Condition at post-test. This exercise intervention had a positive impact on adolescent physical self-perceptions, in particular males, with improvements in those sub domains specifically related to the exercise program. Changes in specific aspects of Physical Self Worth can be facilitated by exercise interventions, after a relatively short period of time, in adolescents with poor motor coordination.
