Differences and Relationship between Body Composition and Motor Coordination in Children Aged 6-7 Years.

BACKGROUND: The primary goal of this study was to investigate the relationship between body composition and motor coordination performance, and the secondary goal was to determine sex differences in body composition and motor coordination of preschool children. METHODS: Forty-eight children (23 boys and 25 girls) underwent assessments for body composition and motor coordination using the Köperkoordinationstest für Kinder (KTK). RESULTS: Linear regression analysis revealed significant associations between body composition and motor coordination in boys (p < 0.05) but not in girls. In boys, Body height (p = 0.01), Total muscle mass (p = 0.03), Total fat (p = 0.03), and Total water (p = 0.02) show statistically significant influence on single-leg jumps. Similar results were obtained for lateral jumps where there was a statistically significant influence of Body height (p = 0.01), Total muscle mass (p = 0.03), and Total water (p = 0.02). Interestingly, predictive variables showed no statistically significant influence on KTK overall score in boys (p = 0.42) nor in girls (p = 0.90). CONCLUSIONS: The predictive system of morphological variables demonstrated significance only among boys in this age group and sample. Girls outperformed boys due to early maturation, resulting in better average KTK scores.

The feasibility of using the Körperkoordinationstest fur Kinder (KTK) in a U.S. elementary physical education setting to assess gross motor skills specific to postural balance.

Introduction: For the past ten years, falls have been the leading cause of nonfatal injuries for all age groups less than 15 years old. A significant rise in childhood sedentary behavior in schools and limited opportunities to be outside has led to motor coordination deficits which have contributed to fall injuries. Method: A German assessment tool, the Körperkoordinationstest fur Kinder (KTK), which has been used for decades in Western European countries, allows researchers and physical education teachers to evaluate typical and atypical children's motor coordination competencies related to dynamic postural balance successfully. No research has been published on the use of this assessment tool in the United States. If its use were found to be feasible in this country for identifying motor coordination deficits in typical and atypical children, it would close the gap in determining motor coordination. Therefore, this study sought in Phase 1 to determine the feasibility of using the KTK assessment in U.S. children and Phase 2 sought to determine the adaptability of the scoring protocol from use in other countries to the United States. Results: The Phase 1 results revealed the KTK assessment was feasible to administer in U.S. physical education class by addressing three challenges for U.S. schools: 1) KTK implementation, 2) time to assess each skill, and 3) the equipment availability and cost to implement the test in a physical education setting. In Phase 2, the researchers were able to determine the raw scores and motor quotient scores in this population and then were able to show similar scoring trends between U.S. children and Flemish children from a previous study. Conclusion: This assessment tool was deemed feasible and adaptable which is the first step to use the KTK in U.S. physical education elementary school settings.

Examination of basic motor skills in children and adolescents.

Aim of the study: The aim of this study was the investigation of basic motor skills in 5-14-year-old boys and girls. Materials and Methods: A total of 842 primary school children, 421 boys and 421 girls, participated in the study. 13.3% of the participants were 5-6 years old, 29.5% were 7-8 years old, 21.5% were 9-10 years old, 16.4% were 11-12, and 19.4% were 13-14 years old. The balance skills of the participants were measured with the (Körperkoordinationstest für Kinder) KTK test. Findings: When the classification of children according to KTK defining classes is examined, 40.7% are very good. When the children's KTK Backward Balancing scores were examined, a statistically significant difference was found between gender and age groups (p < 0.05). Girls between the ages of 5-6 and 7-8 years had a higher score for KTK backward balance. KTK Total scores were examined according to the Body Mass Index groups, when the total scores of KTK were compared, the lowest scores were in the obese group. Conclusion: According to the study results, age is an essential factor for balance skills. As the age increased, the overall scores of the KTK increased. It was determined that girls' KTK backward balancing scores were higher than boys. According to BMI results, the balance performances of obese children were found to be lower than the other groups. This difference can be explained by the negative effect of obesity in this age group. According to these results, it may be recommended to observe and improve the balance performances of obese children.

Gross motor coordination in relation to weight status: a longitudinal study in children and pre-adolescents.

Introduction: Gross Motor Coordination (GMC) is crucial for the adequate development of motor competence. Our purpose in this semi-longitudinal study was to evaluate the influence of BMI on GMC in children and pre-adolescents of both sexes, across school years (classes). Methods: We evaluated 117 subjects (aged 8-13 years) belonging to three different cohorts for 4 consecutive years, providing data over 6 years (classes). GMC was assessed through the Körperkoordinationstest für Kinder (KTK) test. Class and weight status effects were then evaluated by dividing the subjects into a normal weight group and an overweight group based on their weight status. Results: A significant increase across classes was found for BMI (p < 0.001) and KTK raw score (p < 0.001) and a decrease was found for KTK normalized score (MQ) (p = 0.043). Significantly lower MQ values were found for girls. Absolute GMC increased across the years and there was no difference between boys and girls. Correlations between GMC scores and BMI were negative and significant in 5 of 6 classes. It was confirmed that overweight subjects had lower MQ and RAW values than normal-weight subjects, with no class-by-weight status interaction. Discussion: The level of competence and its development are strictly dependent on weight status during childhood and pre-adolescence. The present investigation suggests that the adequate development of GMC requires not only targeted physical education programs but also the promotion of healthy habits aimed at maintaining a normal weight status during childhood and pre-adolescence.

Primary School Pupils: Unequal GMC Developmental Pathways in a Single School Year.

Gross motor coordination (GMC) is essential for the development of specific motor skills and long-term participation in physical activities and sports. Group analysis reveals that, on average, children develop these skills gradually; however, how individuals develop GMC is less clear. The main aim of this study is to increase the understanding of developmental patterns within one school year, and whether children's grade, gender, or baseline GMC proficiency are associated with these developmental patterns. In total, 2594 Dutch children aged 6−12 years performed the modified Körper Koordinations Test für Kinder (KTK3+) twice in one school year (autumn and spring). The KTK3+ includes four subtests: walking backwards, moving sideways, jumping sideways, and eye-hand coordination (EHC) test. On average, children developed significantly on all subtests (p < 0.001). At baseline, children in higher grades scored significantly higher than children in lower grades, and children in grades 5 and 6 (age 9 and 10 years) showed most development (raw scores on average, p < 0.001). Boys outperformed girls on EHC across all grades, whereas girls outperformed boys on walking backwards. Nevertheless, both boys and girls developed similarly. Children with lower scores at baseline developed more quickly across all grades. Noteworthy is that 12.1−24% (depending on the test item) of the children scored lower in the spring than in the autumn tests. On average, children develop their GMC; however, we report large differences in their individual trajectories and note that a substantial number did not show a positive GMC development. Further research should examine GMC development with more possible influencing factors as well as over a longer time span to better understand differences in children's GMC development. This may result in more individualized programs in PE lessons, enabling children to optimally develop their GMC, and better use of GMC assessment tools to monitor children's development.

Trends in gross body coordination and cardiorespiratory fitness-a hierarchical Bayesian Analysis of 35 000 2nd Graders.

OBJECTIVE: A negative decline of motor competence in children has been observed over the last decades. Though most studies derive their inferences from only two distant points in time and thus neglect to investigate the variability of the temporal trends. METHODS: Between the year 2000 and 2011, 35 018 second graders performed the Körperkoordinationstest für Kinder (KTK), consisting of four items (WB, HH, JS, and MS) and a six minute run test (6MRT). A hierarchical Bayesian regression model with varying intercepts and temporal trends was fitted to the data. Age, sex, and BMI categories were included as input variables. The outcome variables were z-standardized to the initial cohort. RESULTS: In all four KTK items, we observed a yearly decline of -0.020 (95% UI -0.038 to -0.001) for WB, -0.054 (95% UI -0.071, -0.037) for HH, -0.028 (95% UI -0.045 to -0.012) for JS and -0.088 (95% UI -0.108 to -0.067) for MS. For the 6MRT, no trend was identified. Overweight and obese children showed a disadvantage in all tests scores. Negative time interactions were observed for overweight and obese children in HH and JS. A substantial between-city variation for all temporal trends was observed. The predictive validation for all models but MS was successful. CONCLUSION: A general negative decline was confirmed for coordinative abilities but not in cardiorespiratory fitness. For all outcome variables, a substantial between-city variation was observed, highlighting the importance of environmental factors in motor development. Overweight and obese children demonstrated an urgent need for action.

Gross Motor Coordination: We Have a Problem! A Study With the Körperkoordinations Test für Kinder in Youth (6-13 Years).

The main goal of our cross-sectional research was to determine the current values of gross motor coordination (GMC) of Italian boys and girls between 6 and 13 years of age. Secondary goals were to study gender differences, and the four subtests trend with ages. Results were compared with the references proposed by KTK authors and with similar searches. Anthropometric measurements and KTK data from 2,206 schoolchildren (girls: n = 1,050; boys: n = 1,156) were collected. The KTK raw score (RS) increased with the age of the subjects (r = 0.678; p < 0.001). In 11-13-year-old subjects, the increase in results is less than in younger subjects. RS showed differences by gender (F = 5.899; p = 0.015) and age (F = 269.193; p < 0.001) without interaction gender × age. Motor quotient (MQ) tended to decrease with age (r = -0.148; p < 0.001); it showed differences by gender (F = 79.228; p < 0.001), age (F = 14.217; p < 0.001), and an interaction gender × age (F = 2.249; p < 0.05). Boys showed better performance than did girls in the raw scores of three of four subtests (JS: F = 24.529; MS: F = 9.052; HH: F = 11.105). Girls show better performances than did boys in the WB (F = 14.52). Differences between genders make us believe it appropriate to maintain a differentiated standardization. RS increased with age, and it seems reasonable, therefore, to maintain a GMC age-based normalization. On the contrary, MQ tended to decrease. All this makes us speculate that today's young people accumulate less significant motor experiences over the years compared to those achieved by their peers in the 1970s. Italian data were lower than German references and Belgian results but slightly higher than the Brazilian ones. The comparison among these four searches confirmed a worrying downward trend in GMC and its characterization by geographical and sociocultural areas. Updated parameters of the KTK can provide helpful references to improve policies to support physical activity, sport, and physical education in youth.

Desempenho motor e índice de massa corporal em crianças de cinco anos / Motor performance and body mass index in children of five years

As crianças estão cada vez mais utilizando brincadeiras e jogos eletrônicos, passando muitas horas diante da televisão e isso pode atrapalhar o processo de desenvolvimento motor bem como o desenvolvimento do processo de sobrepeso e obesidade. A educação física escolar é um importante aliado na promoção de hábitos de vida mais ativos, sendo a educação infantil a primeira etapa de escolarização e prática de atividades motoras desta fase é fundamental. O objetivo desse estudo foi avaliar o índice de massa corporal (IMC) e o desempenho motor de escolares com idade de cinco anos dos Centros Municipais de Educação Infantil em Divinópolis/MG. O desempenho motor foi avaliado com o Teste de Coordenação Corporal para Crianças (Körperkoodinations test Für Kinder ­ KTK) composto por quatro testes: equilibrar-se andando de costas, saltos monopedais, saltos laterais e transposição lateral sobre plataforma. O IMC foi calculado a partir de medidas de peso e altura. Os resultados do presente estudo demonstram que 80,65% da amostra apresenta deficiência na coordenação motora, e quando comparado entre os sexos, os meninos apresentaram melhor coordenação motora que as meninas. Ao analisar o IMC e a coordenação motora não foi encontrada qualquer relação significativa entre eles. Pode-se concluir com o presente estudo que o IMC não influenciou no desempenho motor dos alunos, e que a maioria dos alunos está com a coordenação motora abaixo do esperado. A falta de aulas de educação física com o professor especialista e estímulos específicos para o desenvolvimento motor podem ter contribuído para os resultados encontrados neste estudo, reforçando a necessidade do professor de educação física n o ensino infantil.(AU)

: Children are increasingly using games and electronic games, spending many hours in front of the television and this can hinder the process of motor development as well as the development of overweight and obesity. School physical education is an important ally in the promotion of more active life habits, with early childhood education being the first stage of schooling and the practice of motor activities in this phase is fundamental. The objective of this study was to evaluate the body mass index (BMI) and the motor performance of schoolchildren aged five years old from the Municipal Centers of Early Childhood Education in Divinópolis / MG. Motor performance was assessed with the Body Coordination Test for Children (Körperkoordinations test Für Kinder - KTK) composed of four tests: balance on your back, single-legged jumps, lateral jumps and lateral transposition on a platform. BMI was calculated from weight and height measurements. The results of the present study showed that 80.65% of the sample has impaired motor coordination, and when compared between genders, boys showed better motor coordination than girls. When analyzing BMI and motor coordination, no significant relationship was found between them. It can be concluded with the present study that the BMI did not influence the motor performance of the students, and that the majority of the students have motor coordination below the expected. The lack of physical education classes with the specialist teacher and specific stimuli for motor development may have contributed to the results found in this study, reinforcing the need for physical education teachers in early childhood education.(AU)

Individual, Family, and Environmental Correlates of Motor Competence in Young Children: Regression Model Analysis of Data Obtained from Two Motor Tests.

Physical activity and motor competence (MC) have been considered to be closely related and prevent childhood obesity. The aim of the study was two-fold: to examine MC measured with two different tools in relation to individual, family, and environmental correlates and to investigate gender differences in MC. The Test of Gross Motor Development-Third Edition (TGMD-3) was administered to three- to seven-year-old children (n = 945), while the Körperkoordinationstest für Kinder (KTK) was also used for five- to seven-year-old children (n = 444). The parent questionnaire (n = 936) included questions about individual (e.g., participation in organized sports), family (e.g., parents' education level), and environmental (e.g., access to sports facilities) correlates. The children's temperament was assessed using the Colorado Childhood Temperament Inventory (CCTI) questionnaire. Data were analyzed using one-way analysis of variance and linear mixed-effects regression models. The regression models explained 57% and 38% of the variance in TGMD-3 and KTK, respectively. Individual correlates, including older age, more frequent participation in sports, and specific temperament traits of activity and attention span-persistence, were the strongest predictors for better MC. Small gender differences were found in both assessment tools, albeit in a different manner. In conclusion, socioecological correlates of MC in young children are multidimensional, and individual correlates appear to be the most important predictors of MC. Importantly, the correlates can differ according to the MC assessment tools.

New Insight on Motor Behavior: The Link Between the Hopping Task and the Tracing Performance as Hint of Gross and Fine Motor Functions.

The gross motor coordination tasks are thought to be likely not linked to the fine motor coordination tasks. The authors aimed to investigate this matter through a network analysis linking graphomotor (by tablet PC tracing), gross coordination (by Körperkoordinationstest für Kinder items), and strength (by handgrip) parameters in school children. Interestingly, the authors found that "Hopping" was the strongest central node, with linkages to "Quality" and "Speed" on tracing test. Handgrip strength did not link to gross coordination and graphomotor parameters, except with "Pressure." Graphomotor performances suggested substantial peculiarities in developmental trajectories. Sport participation did not influence gross coordination nor graphomotor performances. The authors suggest considering the functional link between hopping and graphomotricity both in planning physical education and in understanding coordination impairments, through the developmental trajectories.

Socioecological correlates of perceived motor competence in 5- to 7-year-old Finnish children.

We investigated child, family, and environmental factors associated with young children's perceptions of locomotor (LM) and object control (OC) skills. The participants comprised 472 children (6.22 ± 0.63) and their parents. The children were assessed for their perception of motor competence in LM and OC skills (using the pictorial scale of Perceived Movement Skill Competence for young children), and actual motor competence (Test of Gross Motor Development 3rd edition and Körperkoordinationstest Für Kinder). Anthropometrics were calculated using the children's body mass index standard deviation scores. A parent questionnaire included questions about child factors (sex, child's independent walking age, time spent sedentary and outdoors, participation in organized sport activities, and access to electronic devices), family factors (parent educational level, physical activity frequency, and sedentary behavior), and environmental factors (access to sport facilities). Variance analysis sought to identify age-related differences, and a linear regression model examined correlates of children's perception of LM and OC skills. The children's movement skill perceptions were found to be generally high. Four factors explained 5.7% of the variance in perceptions of LM skills and 7.5% of the variance in perceptions of OC skills. Two factors, lower age and higher actual motor competence, explained most of the children's skill perceptions. Access to electronic devices (less) and Body mass index (BMI) (higher) were associated with perceptions of LM skills. Participation in organized sport activities (higher) and parental education (lower) were associated with perceptions of OC skills. When promoting children's physical activity and motor competence, perceptions of motor competence are an important consideration.

Multivariate Relationships among Morphology, Fitness and Motor Coordination in Prepubertal Girls.

Motor coordination and physical fitness are multidimensional concepts which cannot be reduced to a single variable. This study evaluated multivariate relationships among morphology, physical fitness and motor coordination in 74 pre-pubertal girls 8.0-8.9 years of age. Data included body dimensions, eight fitness items and four motor coordination tasks (KTK battery). Maturity status was estimated as percentage of predicted mature stature attained at the time of observation. Canonical correlation analysis was used to examine the relationships between multivariate domains. Significant pairs of linear functions between indicators of morphology and fitness (rc = 0.778, Wilks' Lambda = 0.175), and between fitness and motor coordination (rc = 0.765, Wilks' Lambda = 0.289) were identified. Girls who were lighter and had a lower waist-to-stature ratio and % fat mass attained better scores in the endurance run, sit-ups and standing long jump tests, but poorer performances in hand grip strength and 2-kg ball throw. Better fitness test scores were also associated with better motor coordination scores. Relationships between body size and estimated fatness with motor fitness suggested an inverse relationship that was particularly evident in performance items that required the displacement of the body through space, while motor coordination was more closely related with fitness than with somatic variables.

Uso del test KTK como instrumento de evaluación de la coordinación motora gruesa entre los 6 y 11 años de edad en hombres y mujeres / Use of the KTK test as an instrument for the assessment of gross motor coordination between 6 and 11 year old boys and girls

En el siguiente apartado se pretende realizar un metaanálisis referente al test KTK de evaluación de coordinación motora posterior a la previa revisión bibliográfica efectuada en las distintas ba-ses de datos como, EBSCO, SciELO, Google académico y Dialnet. Los artículos de los cuales se extrajo información referente al test motor KTK corresponden entre los años 2003 a 2017. La metodología utilizada fue selectiva, priorizando aquellos artículos que tengan relación con el test motor KTK. Los resultados fueron procesados a través de la herramienta estadística de Microsoft office Excel, obteniendo como resultando en el índice de correlación de Pearson 0.981, Por lo que se concluye que los sujetos evaluados presentan una gran similitud en los resultados del test motor KTK.

In the following section, a meta-analysis is intended to be performed on the KTK motor coordi-nation test, after a previous bibliographic revision of different databases, such as EBSCO, SciELO, Google Scholar and Dialnet, is carried out. The articles from which information about the KTK motor test was extracted from correspond to publications between the years 2003 and 2017. The methodology used was selective, prioritizing those articles related to the KTK motor test. The re-sults were processed through the statistical tool Microsoft office excel, obtaining 0.981 as a result in the Pearson correlation index. Thus, it can be concluded that the subjects evaluated show great similarity with the KTK motor test results.

Flexibility is associated with motor competence in schoolchildren.

Available data on the associations between motor competence (MC) and flexibility are limited and result inconclusive. This study aims to examine the relationship between flexibility and MC in children. The sample comprised 596 Portuguese children (47.1% girls) aged 9.7 ± 0.6 years. Motor competence was evaluated with the body coordination test, Körperkoordination Test für Kinder. Cardiorespiratory fitness (20-m shuttle run), muscular strength (curl-up and push-up tests), and flexibility (back-saver sit and reach and trunk-lift tests) were evaluated using the Fitnessgram Test Battery. Z-scores by age and gender for the physical fitness tests were constructed. Analysis of variance and regression analysis were performed. Participants in the healthy zone groups of both flexibility tests exhibited significantly better scores of MC than the participants under the healthy zone (P < 0.001). Back-saver sit and reach and trunk-lift Z-scores, either individually or as a sum, were significant predictors of MC (P < 0.05 for all) after adjustments for the other physical fitness components, age, body mass index, and socioeconomic status, in both genders. Our findings highlight the importance of promoting and developing flexibility, as well as the other health-related physical fitness components in schoolchildren to reach adequate levels of MC.

Effectiveness of a 16 week gymnastics curriculum at developing movement competence in children.

OBJECTIVES: Internationally, children's movement competence levels are low. This study's aim was to evaluate the effectiveness of a 16 week gymnastics curriculum on stability, locomotive and object control skills and general body coordination. It was hypothesised that the gymnastics intervention group would demonstrate significant improvements beyond a PE comparison group. DESIGN: This study used a non-randomised control design. The intervention and comparison groups were drawn from three primary schools. The study followed the transparent reporting of evaluations with nonrandomized designs (TREND) statement for reporting. METHODS: A total of 333 children (51% girls, 41% intervention) with a mean age of 8.1 years (SD=1.1) participated. Intervention children (16 weeks×2h of gymnastics) were compared to children who received (16×2h) standard PE curriculum. Children's movement competence was assessed using the Test of Gross Motor Development-2, Stability Skills Assessment and the Körper-Koordinationstest für Kinder. Multilevel linear mixed models, accounting for variation at the class level and adjusted for age and sex, were used to assess intervention relative to comparison differences in all aspects of movement competence. RESULTS: Stability and object control skills showed a significant (p<0.05) intervention×time interaction effect. No difference was found in locomotor skills or general coordination. CONCLUSIONS: Gymnastics is effective at developing stability skills and object control skills without hindering the development of locomotor skills or general coordination. Accelerated learning of stability skills may support the development of more complex movement skills.

Independent and Combined Effects of Sex and Biological Maturation on Motor Coordination and Performance in Prepubertal Children.

Sex differences and maturation-associated variation in fitness and motor coordination were examined in children aged 8-9 years (n = 128, 67 girls). Assessments included stature and body mass, two-component body composition, percentage of predicted adult stature (as an index of biological maturation), and motor performance and coordination (Körperkoordinationstest für Kinder). Compared to girls, boys were less advanced in maturation status, possessed larger fat mass, demonstrated superior performances in six tests of fitness, and obtained one superior score on the Körperkoordinationstest für Kinder. After controlling for somatic maturation, sex differences persisted in the two multivariate domains: motor performance and motor coordination.

Cross-cultural comparison of motor competence in children from Australia and Belgium.

Motor competence in childhood is an important determinant of physical activity and physical fitness in later life. However, childhood competence levels in many countries are lower than desired. Due to the many different motor skill instruments in use, children's motor competence across countries is rarely compared. The purpose of this study was to evaluate the motor competence of children from Australia and Belgium using the Körperkoordinationstest für Kinder (KTK). The sample consisted of 244 (43.4% boys) Belgian children and 252 (50.0% boys) Australian children, aged 6-8 years. A MANCOVA for the motor scores showed a significant country effect. Belgian children scored higher on jumping sideways, moving sideways and hopping for height but not for balancing backwards. Moreover, a Chi squared test revealed significant differences between the Belgian and Australian score distribution with 21.3% Belgian and 39.3% Australian children scoring "below average." The very low levels reported by Australian children may be the result of cultural differences in physical activity contexts such as physical education and active transport. When compared to normed scores, both samples scored significantly worse than children 40 years ago. The decline in children's motor competence is a global issue, largely influenced by increasing sedentary behavior and a decline in physical activity.

The role of general dynamic coordination in the handwriting skills of children.

Difficulties in handwriting are often reported in children with developmental coordination disorder, and they represent an important element in the diagnosis. The present study was aimed at investigating the relation between motor coordination and handwriting skills, and to identify differences in handwriting between children without and with coordination difficulties. In particular, we asked whether visual-spatial skills have a role as mediating variables between motor coordination and handwriting. We assessed motor coordination as well as graphic abilities in children aged 7-10 years. Moreover, we evaluated their visual-motor integration, visual-spatial skills, and other cognitive abilities (memory and planning). We found no relation between motor coordination and handwriting skills, while visual-spatial skills (measured by a visual-constructive task) were related with both. Our conclusion is that visual-spatial skills are involved both in general motor coordination and in handwriting, but the relationship involves different aspects in the two cases.

Sensitivity and specificity of different measures of adiposity to distinguish between low/high motor coordination / Sensibilidade e especificidade de diferentes medidas de adiposidade para diferenciação entre pouca/ampla coordenação motora / Sensibilidade e especificidade de diferentes medidas de adiposidade para diferenciação entre pouca/ampla coordenação motora

OBJECTIVE: This study aimed to determine the ability of different measures of adiposity to discriminate between low/high motor coordination and to evaluate the relationship between different measures of adiposity and motor coordination. METHODS: This study included 596 elementary school children aged 9 to 12 years (218 females - 47.1%). Weight, height, and waist circumference were objectively measured by standardized protocols. Body fat percentage was estimated by bioelectric impedance. Body mass index and waist-to-height ratio were computed. Motor coordination was assessed by the Körperkoordination Test für Kinder. Cardiorespiratory fitness was predicted by a maximal multistage 20 m shuttle-run test of the Fitnessgram Test Battery. A questionnaire was used to assess the maternal educational level. RESULTS: The receiver operating characteristic performance of body fat percentage in females and waist circumference in males presented a slightly better discriminatory accuracy than body mass index, waist circumference and waist-to-height ratio in predicting low motor coordination. After adjustments, logistic regression analyses showed that body mass index (ß = 2.155; 95% CI: 1.164-3.992; p = 0.015 for girls; ß = 3.255; 95% CI: 1.740-6.088; p < 0.001 for males), waist circumference (ß = 2.489; 95% CI: 1.242-4.988; p = 0.010 for girls; ß = 3.296; 95% CI: 1.784-6.090; p < 0.001 for males), body fat percentage (ß = 2.395; 95% CI: 1.234-4.646; p = 0.010 for girls; ß = 2.603; 95% CI: 1.462-4.634; p < 0.001 for males) and waist-to-height ratio (ß = 3.840; 95% CI: 2.025-7.283; p < 0.001 for males) were positively and significantly associated with motor coordination in both sexes, with the exception of waist-to-height ratio in girls (ß = 1.343; 95% CI: 0.713-2.528; p = 0.381). CONCLUSION: Body fat percentage and waist circumference showed a slightly better discriminatory accuracy in predicting low motor coordination for females and for ...

OBJETIVO: Este estudo pretende: (i) determinar a capacidade de diferentes medidas de adiposidade para diferenciar pouca/ampla CM; e (ii) avaliar a relação entre diferentes medidas de adiposidade e coordenação motora. MÉTODO: 596 crianças em idade escolar fundamental, de 9 a 12 anos (218 meninas - 47,1%) participaram deste estudo. O peso, a altura e a circunferência da cintura foram mensurados objetivamente pelos protocolos padronizados. O percentual de gordura corporal foi estimado pela impedância bioelétrica. Foram calculados o índice de massa corporal e a razão cintura/estatura. A coordenação motora foi avaliada por meio do teste de coordenação corporal para crianças. A capacidade cardiorrespiratória foi predita por um teste shuttle-run multinível de no máximo 20 m da Bateria de Testes Fitnessgram. Foi usado um questionário para avaliar o nível de escolaridade das mães. RESULTADOS: O desempenho na curva de característica de operação do receptor do percentual de gordura corporal, em meninas, e da circunferência da cintura, em meninos, demonstrou uma precisão discriminatória levemente melhor que o índice de massa corporal, a circunferência da cintura e a razão cintura/estatura em predizer pouca coordenação motora. Após ajustes, as análises de regressão logística demonstraram que o índice de massa corporal (ß = 2,155; Intervalo de Confiança (IC) 95%: 1,164-3,992; p = 0,015 para meninas; ß = 3,255; IC 95%: 1,740-6,088; p < 0,001 para meninos), a circunferência da cintura (ß = 2,489; IC 95%: 1,242-4,988; p = 0,010 para meninas; ß = 3,296; IC 95%: 1,784-6,090; p < 0,001 para meninos), o percentual de gordura corporal (ß = 2,395; IC 95%: 1,234-4,646; p = 0,010 para meninas; ß = 2,603; IC 95%: 1,462-4,634; p < 0,001 para meninos) e a razão cintura/estatura (ß = 3,840; IC 95%: 2,025-7,283; p < 0,001 para meninos) estavam positiva e significativamente relacionados à coordenação motora em ambos os sexos, com exceção da razão cintura/estatura ...

Sensitivity and specificity of different measures of adiposity to distinguish between low/high motor coordination.

OBJECTIVE: This study aimed to determine the ability of different measures of adiposity to discriminate between low/high motor coordination and to evaluate the relationship between different measures of adiposity and motor coordination. METHODS: This study included 596 elementary school children aged 9 to 12 years (218 females - 47.1%). Weight, height, and waist circumference were objectively measured by standardized protocols. Body fat percentage was estimated by bioelectric impedance. Body mass index and waist-to-height ratio were computed. Motor coordination was assessed by the Körperkoordination Test für Kinder. Cardiorespiratory fitness was predicted by a maximal multistage 20 m shuttle-run test of the Fitnessgram Test Battery. A questionnaire was used to assess the maternal educational level. RESULTS: The receiver operating characteristic performance of body fat percentage in females and waist circumference in males presented a slightly better discriminatory accuracy than body mass index, waist circumference and waist-to-height ratio in predicting low motor coordination. After adjustments, logistic regression analyses showed that body mass index (ß=2.155; 95% CI: 1.164-3.992; p=0.015 for girls; ß=3.255; 95% CI: 1.740-6.088; p<0.001 for males), waist circumference (ß=2.489; 95% CI: 1.242-4.988; p=0.010 for girls; ß=3.296; 95% CI: 1.784-6.090; p<0.001 for males), body fat percentage (ß=2.395; 95% CI: 1.234-4.646; p=0.010 for girls; ß=2.603; 95% CI: 1.462-4.634; p<0.001 for males) and waist-to-height ratio (ß=3.840; 95% CI: 2.025-7.283; p<0.001 for males) were positively and significantly associated with motor coordination in both sexes, with the exception of waist-to-height ratio in girls (ß=1.343; 95% CI: 0.713-2.528; p=0.381). CONCLUSION: Body fat percentage and waist circumference showed a slightly better discriminatory accuracy in predicting low motor coordination for females and for males, respectively.
