RESUMO

La Educación Física ha demostrado ser una herramienta eficaz para desarrollar condiciones físicas y mentales en el ser humano. Sin embargo, aún las propuestas a favor de hacer realidad la educación inclusiva en estudiantes con trastorno del espectro autista no logra los niveles mundialmente esperados. Es por ello que en esta obra se plantea como objetivo diseñar un sistema de juegos inclusivos para el desarrollo de la coordinación motriz en estudiantes con trastorno del espectro autista, en la clase de Educación Física. Para lograr este propósito se emplearon como métodos fundamentales del nivel empírico la encuesta, la prueba pedagógica y la observación. Los resultados del diagnóstico apuntan a un deficiente conocimiento por parte de los docentes de Educación Física sobre el tratamiento de los estudiantes con este trastorno, por lo que se procede a la tarea de elaborar un sistema de juegos para el desarrollo de la coordinación motriz que gradualmente los incorpore a la socialización en el grupo, y un sistema evaluativo pertinente donde se pudieron apreciar resultados superiores cuantitativa y cualitativamente.

A Educação Física tem se mostrado uma ferramenta eficaz para desenvolver as condições físicas e mentais do ser humano. No entanto, mesmo as propostas a favor de tornar a educação inclusiva uma realidade para alunos com perturbação do espectro do autismo não atingem os níveis globalmente esperados. Por isso o objetivo deste trabalho é desenhar um sistema de jogos inclusivos para o desenvolvimento da coordenação motora em alunos com transtorno do espectro do autismo, na aula de Educação Física. Para atingir este propósito, o inquérito, o teste pedagógico e a observação foram utilizados como métodos fundamentais a nível empírico. Os resultados do diagnóstico apontam para pouco conhecimento por parte dos professores de Educação Física sobre o tratamento dos alunos com esse transtorno, por isso passam à tarefa de desenvolver um sistema de jogos para o desenvolvimento da coordenação motora que os incorpore gradativamente à socialização em o grupo, e um sistema avaliativo pertinente onde resultados superiores pudessem ser vistos quantitativa e qualitativamente.

Physical Education has proven to be an effective tool to develop physical and mental conditions in human beings. However, even the proposals in favor of making inclusive education a reality for students with autism spectrum disorder do not achieve the globally expected levels. That is why, the objective of this work is to design a system of inclusive games for the development of motor coordination in students with autism spectrum disorder, in the Physical Education class. To achieve this purpose, the survey, the pedagogical test and observation were used as fundamental methods at the empirical level. The results of the diagnosis point to poor knowledge on the part of Physical Education teachers about the treatment of students with this disorder, so it is proceed to the task of developing a system of games for the development of motor coordination that gradually incorporated them into socialization in the group, and a pertinent evaluative system where superior results could be seen quantitatively and qualitatively.

RESUMO

There are numerous studies comparing young and old adults in terms of muscle coordination in standard tasks (e.g., walking, reaching) and small variations of them. These tasks might hide differences: individuals would converge to similar behavior as they practice these throughout life. Also, we are unaware of studies that considered the muscle recruitment nested dynamics. For this reason, our study evaluated how young and old women coordinate and control the movement system while performing an unusual redundant motor control task through the network physiology approach. We acquired electromyographic signals from nine leg muscles of the dominant and non-dominant limbs during maximum voluntary isometric contractions (knee extension and flexion) and co-contraction bouts. Our results showed that young participants presented higher peak torque output, with similar EMG variability, compared to older participants. Considering firing rate frequencies, old and young women demonstrated different traits for network clustering and efficiency for the task. Age seems to affect muscle coordination at higher frequencies, even with a similar number of muscle synergies, indicating that younger women might have more integrated synergies than older women. The findings also point to differential muscle coordination adaptability.

RESUMO

Purpose: The objective of this research was to develop a musical digital game for rehabilitation of upper limb and to verify its usability and user experience with professionals in the field (physical therapists). Materials and Methods: Thirty working professionals were recruited to evaluate the system. The usability was evaluated with the System Usability Scale (SUS) and the user experience was verified with the Game Flow scale. Results: The overall score of the SUS scale was 88.67 (±9.129); this score is interpreted as "Best Imaginable" (86-100). The user experience rating had most of its domains equal or higher than 4, which indicates that all the requirements for a good user experience were present in the game. Conclusions: The Moniz Game proved to be a game with good usability and can be a tool for application in clinical practice regarding motor coordination. However, further studies are needed to evaluate the effect of the Moniz Game on motor coordination in patients with neurological dysfunctions.

RESUMO

Venom-derived peptides are important sources for the development of new therapeutic molecules, especially due to their broad pharmacological activity. Previously, our research group identified a novel natural peptide, named fraternine, with promising effects for the treatment of Parkinson's disease. In the present paper, we synthesized three peptides bioinspired in fraternine: fra-10, fra-14, and fra-24. They were tested in the 6-OHDA-induced model of parkinsonism, quantifying motor coordination, levels of TH+ neurons in the substantia nigra pars compacta (SN), and inflammation mediators TNF-α, IL-6, and IL-1ß in the cortex. Peptides fra-14 and fra-10 improved the motor coordination in relation to 6-OHDA lesioned animals. However, most of the peptides were toxic in the doses applied. All three peptides reduced the intensity of the lesion induced rotations in the apomorphine test. Fra-24 higher dose increased the number of TH+ neurons in SN and reduced the concentration of TNF-α in the cortex of 6-OHDA lesioned mice. Overall, only the peptide fra-24 presented a neuroprotection effect on dopaminergic neurons of SN and a reduction of cytokine TNF-α levels, making it worthy of consideration for the treatment of PD.

RESUMO

La investigación tuvo como objetivo analizar la relación entre la Coordinación Motora (CM) con el Índice de Masa Corporal en escolares chilenos de entre 7 y 9 años. El estudio fue observacional de corte transversal, con características descriptivas y correlacionales. Se evaluaron a 180 escolares (90 mujeres de 8.4 ± 0.9 años y 90 hombres de 8.5± 0.9 años). Se midieron variables antropométricas de peso y talla. Se calculó el Índice de Masa Corporal (IMC). La coordinación motora (CM) se evaluó utilizando la batería de Körperkoordinationstest Für Kinder (KTK). Los resultados mostraron que en las mujeres el grupo Normopeso tenía un mejor desempeño en la transposición lateral que los grupos Sobrepeso y Obesidad (p˂0.05). En los hombres, el grupo Normopeso superó al grupo Obesidad en los saltos monopedales (p˂0.05). Además, al analizar las diferencias entre sexos, se determinó que las mujeres registraron mayor puntaje que los hombres en el equilibrio a la retaguardia (p<0.05), por su parte, los hombres registraron mejores rendimientos en saltos laterales, transposición lateral y el puntaje total del KTK (p<0.05). Se concluye que existe menor índice de CM en los escolares con elevado IMC, y que existen diferencias significativas entre hombres y mujeres en el equilibrio, saltos laterales, transposición lateral y el puntaje total del test KTK.

The objective of this research was to analyze the relationship between motor coordination (CM) and Body Mass Index in Chilean schoolchildren between 7 and 9 years of age. The study was observational cross-sectional, correlational and descriptive study. 180 students of both sexes were evaluated (90 women aged 8.4 ± 0.9 years and 90 men aged 8.5 ± 0.9 years). Anthropometric weight and height variables were measured and the Body Mass Index (BMI) was calculated. The CM was evaluated using the battery of Körperkoordinationstest Für Kinder (KTK). The results showed that in the lateral transposition, the normal weight group outperforms the overweight and Obesity group (p˂0.05) for women. For men, in monopedal jumps, the normal weight group also outperformed the obesity group (p˂0.05). In addition, when analyzing the differences between the sexes, it was noted that women had a higher score than men in the rear balance (p˂0.05). On the other hand, men had performed better in lateral jumps, lateral transposition and the total KTK score (p˂0.05). In conclusion, the study found that there was a lower CM index in schoolchildren with a high BMI, and that there were significant differences between men and women in terms of balance, lateral jumps, lateral transposition, and the total score of the KTK test.

RESUMO

(1) Background: Developmental coordination disorder (DCD) is a chronic impairment that affects several domains that mark the developmental trajectory from childhood to adulthood. Aim: This study examined the differences in physical and psychosocial factors for children with DCD and typical development (TD) and the associations between these factors with gross motor coordination. (2) Methods: Children with DCD (n = 166; age: M = 8.74, SD = 2.0) and TD (n = 243; Age: M = 8.94; SD = 2.0) attending private and public schools were screened using the MABC-2. Children were then assessed using the Körperkoordination test für Kinder (gross coordination), the Perceived Efficacy and Goal Setting System (self-efficacy), horizontal jump (lower limb strength), and dynamometer (handgrip strength). A semi-structured interview was carried out to examine the oriented physical activity practice in the daily routine, the time spent in the activities, and the use of public spaces to practice non-oriented physical activities. (3) Results: Children with TD showed scores significantly higher than children with DCD in almost all factors with small to very large effect sizes; the exceptions were self-care and daily physical activity. The structural equation model showed that for children with DCD, the BMI explained negatively and significantly the motor coordination (b = -0.19, p = 0.019), whereas physical activity (b = 0.25, p < 0.001), lower limb strength (b = 0.38, p < 0.001), and perceived self-efficacy (b = 0.19, p = 0.004) explained it positively. For children with TD, the BMI explained negatively and significantly the motor coordination (b = -0.23, p = 0.002), whereas physical activity (b = 0.25, p < 0.001) and lower limb strength (b = 0.32, p < 0.001) explained it positively. (4) Conclusions: The authors extended previous research by providing evidence that factors affecting motor coordination vary across childhood for children with DCD and TD. Self-efficacy was relevant only in explaining motor coordination for children with DCD.

RESUMO

Abstract This study aimed to compare the physical profile and motor profile of children from 6 to 10 years old, according to their level of cardiorespiratory fitness (CRF). Participated 2036 children from 6 to 10 years old from São José dos Pinhais - PR. Assessed variables were stature, corporal mass, Body mass index (BMI), physical fitness (PF), and gross motor coordination (GMC). The CRF was assessed by the total distance during the 6 minutes walking test. A battery of tests KTK evaluated the GCM. The children were classified according to their levels of CRF (low-moderate-elevated). Differences between groups were tested using ANOVA one way. Data analysis was made in the SPSS software, with a meaningfulness of 5%. Children with low levels of CRF showed higher values of adiposity. On the PF tests, children with low levels of CRF showed higher values of prehension and worse performance in the other tests. Regarding GMC, children with low levels of CRF had lower coordinative performance. Meaningful differences were found in the comparisons between different groups (low-moderate, low-elevated) with an advantage in the results in moderate levels of CRF. Obtaining average levels of CRF can bring protective benefits in other variables in children's growth process and development during infancy. Evaluating the CRF doesn't only get a momentary evaluation. Still, it can also do the monitoring of an essential variable of health, as well as indicate a predisposition about other physical-motor variables.

Resumo Comparar o perfil físico e motor de crianças dos 6 aos 10 anos, conforme os seus níveis de aptidão cardiorrespiratória (AptC). Participaram do estudo 2036 crianças de seis a 10 anos de idade de São José dos Pinhais-PR. Foram avaliados estatura, massa corporal, índice de massa corporal (IMC), aptidão física (AptF) e coordenação motora (CMG). A AptC foi avaliada pela distância total percorrida no teste de seis minutos. A CMG foi avaliada por meio da bateria de testes KTK. As crianças foram classificadas em função dos níveis de AptC (baixo-moderado-elevado). Diferenças entre grupos foram testadas utilizando da ANOVA one way. As análises dos dados foram realizadas no software SPSS, com nível de significância em 5%. Crianças com menor nível de AptC apresentam maiores valores médios adiposidade. Nos testes de AptF, crianças com níveis baixos de AptC apresentaram maiores valores de preensão e pior desempenho nos demais testes. Relativamente à CMG, crianças com baixos níveis de AptC apresentaram piores desempenho coordenativo. Diferenças significativas foram encontradas para as comparações entre os outros grupos (baixo-moderado; baixo-elevado) com vantagem nos resultados nos níveis moderados a elevados de AptC. Obter níveis moderados de AptC pode trazer benefícios protetores em diferentes variáveis do processo de crescimento e desenvolvimento de crianças durante a segunda infância. Avaliar a AptC não traz somente uma avaliação momentânea, como pode ser feito o monitoramento de uma importante variável de saúde bem como indicar uma predisposição sobre outras variáveis físico-motoras.

RESUMO

The evaluation of animal locomotor activity is a behavioral tool widely used to measure the mechanisms underlying a particular disease, disorder, or injury, as well as the effects of exposure to a xenobiotic. The elevated beam test is one of the most used tests in rodents to assess balance and motor coordination. Despite being inexpensive and utilizing a simple apparatus, the high beam test requires a long period of animal training and habituation. The development and characterization of an alternative test, namely the gait test, has the potential to circumvent the time and effort required for animal training, deeming it an effective, inexpensive, and fast method for the analysis of behaviors that are comparably assessed by the high beam test. Therefore, the present study focused on determining the effectiveness and feasibility of the gait test for assessing rodent locomotion and balance as a replacement for the elevated beam test. For this purpose, male rats were divided into three groups: one control group exposed to a saline solution (NaCl 0.9%) and two experimental groups exposed to a single dose of either 0.2 or 1.0 mg/kg of ivermectin intraperitoneally for induction of locomotor disturbance. The high beam and gait tests were performed 15 min and 24 h after drug administration. Results show that the experimental groups had difficulty performing the tasks of either test at both time points analyzed compared to the control groups. At the high beam, experimental animals had trouble maintaining balance and walking. At the gait test, experimental animals showed alterations in gait, which were quantitated by: (a) shortening of step length, (b) decrease of stride, (c) altered step symmetry, and (d) altered stride area. Such results are indicative of compensatory efforts and were comparable between both tests. Altogether, the data indicate that the gait test meets all requirements for assessing motor coordination in rodents. The gait test is therefore validated as a complement to the elevated beam test for the study and analysis of neurodegenerative impairment and other disorders involving neuromuscular disturbances.(AU)

A avaliação da atividade locomotora animal é uma ferramenta comportamental bastante utilizada para mensurar os mecanismos subjacentes a uma determinada doença, distúrbio ou lesão e efeitos da exposição a um xenobiótico. Um dos testes mais utilizados em roedores para avaliar o equilíbrio e coordenação motora é o teste da trave elevada que, apesar de ser um teste barato e que exige um aparato simples, é necessário um longo período de treino e habituação dos animais. O desenvolvimento e caracterização de um teste alternativo, chamado de teste da marcha, tem o potencial de contornar o tempo e o esforço necessários ao treino dos animais, considerando-o um método eficaz, barato e rápido para a análise de comportamentos avaliados comparativamente pelo alto teste de feixe. Portanto, o presente estudo concentrou-se em determinar a eficácia e viabilidade do teste de marcha para avaliação da locomoção e equilíbrio de roedores em substituição ao teste da trave elevada. Para isso, ratos machos foram divididos em 3 grupos, sendo 1 grupo controle exposto à solução salina (NaCl 0,9%) e 2 grupos experimentais expostos à dose única de 0,2 e 1,0 mg/kg de ivermectina por via intraperitoneal para indução da alteração locomotora. Os testes de trave elevada e marcha foram realizados 15 min e 24 h após a administração da droga. Os resultados mostram que os grupos experimentais tiveram dificuldade em realizar as tarefas de qualquer teste em ambos os momentos analisados em comparação com os grupos de controle. Na trave elevada, os animais experimentais tiveram dificuldade em manter o equilíbrio e andar. No teste de marcha, os animais experimentais apresentaram alterações na marcha, que foram quantificadas por: (a) encurtamento do comprimento da passada, (b) diminuição da passada, (c) alteração da simetria da passada e (d) alteração da área da passada. Tais resultados são indicativos de esforços compensatórios e foram comparáveis entre os dois testes. Em conjunto, os dados indicam que o teste de marcha atende a todos os requisitos para avaliação da coordenação motora em roedores. O teste de marcha é, portanto, validado como um complementar para o teste da trave elevada e para o estudo e análise de comprometimento neurodegenerativo e outros distúrbios envolvendo distúrbios neuromusculares.(AU)

RESUMO

OBJECTIVE: The present study was aimed at analyzing the effect of physical activity on motor coordination in children with ASD. METHODS: On 28 June 2021, a systematic review with meta-analysis was performed using the following databases: MEDLINE, SciELO, LILACS, PEDro, SPORTDiscus, CINAHL, SCOPUS, Web of Science, Cochrane, and Science Direct. We analyzed the methodological quality and risk of bias using the Jadad scale and Cochrane tool, respectively. Motor coordination results were meta-analyzed using the RevMan program. Two independent researchers used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool to assess the level of evidence from the meta-analysis. RESULTS: We found four studies in the listed databases and five randomized clinical trials were included in the meta-analysis that included 109 children with ASD. Children with ASD who performed physical activity did not present significantly better motor coordination than control children (p = 0.12). CONCLUSIONS: Considering the clinical importance of physical activity for children with ASD, this systematic review with meta-analysis showed that physical activity had no statistically significant effects on coordination in individuals with ASD.

RESUMO

Background: Traumatic brachial plexus injury (TBPI) causes a sensorimotor deficit in upper limb (UL) movements. Objective: Our aim was to investigate the arm-forearm coordination of both the injured and uninjured UL of TBPI subjects. Methods: TBPI participants (n = 13) and controls (n = 10) matched in age, gender, and anthropometric characteristics were recruited. Kinematics from the shoulder, elbow, wrist, and index finger markers were collected, while upstanding participants transported a cup to their mouth and returned the UL to a starting position. The UL coordination was measured through the relative phase (RP) between arm and forearm phase angles and analyzed as a function of the hand kinematics. Results: For all participants, the hand transport had a shorter time to peak velocity (p < 0.01) compared to the return. Also, for the control and the uninjured TBPI UL, the RP showed a coordination pattern that favored forearm movements in the peak velocity of the transport phase (p < 0.001). TBPI participants' injured UL showed a longer movement duration in comparison to controls (p < 0.05), but no differences in peak velocity, time to peak velocity, and trajectory length, indicating preserved hand kinematics. The RP of the injured UL revealed altered coordination in favor of arm movements compared to controls and the uninjured UL (p < 0.001). Finally, TBPI participants' uninjured UL showed altered control of arm and forearm phase angles during the deceleration of hand movements compared to controls (p < 0.05). Conclusion: These results suggest that UL coordination is reorganized after a TBPI so as to preserve hand kinematics.

RESUMO

RESUMO Nas últimas décadas o uso da Teoria de Resposta ao Item (TRI) tem sido implementada devido à complexidade dos cálculos estatísticos que permite analisar com profundidade testes educacionais, questionários e listas de itens aplicados em diferentes áreas como a psicometria, ranking esportivo e pedagogia. A partir dessa premissa este estudo teve como objetivo verificar a adequabilidade das tarefas motoras do KTK analisando o grau de dificuldade e parâmetro de discriminação de cada tarefa motora. Participaram do estudo 385 crianças de 5 a 14 anos. O instrumento avaliado foi o KTK (Körperkoordinationstest für Kinder), composto por quatro tarefas motoras: trave de equilíbrio, saltos monopedais, saltos laterais e transposição de plataformas. As análises foram conduzidas a partir dos dados brutos adquiridos em cada tarefa motora. A fim de verificar a estrutura fatorial da matriz teórica subjacente ao teste, foi realizada uma análise fatorial exploratória seguida da análise fatorial confirmatória. Os parâmetros de dificuldade e discriminação de cada tarefa motora foram analisados a partir do modelo de resposta gradual, fundamentado na teoria de resposta ao item (TRI). Os resultados corroboram com a estrutura fatorial sugerida na versão original do KTK, apresentando apenas um fator, chamado de coordenação motora. Os indicadores da Análise Fatorial Confirmatória (AFC) foram aceitáveis, indicando boa qualidade do modelo ajustado para a amostra. Conclui-se que a análise de TRI evidenciou diferenças nos parâmetros de dificuldade e de discriminação entre as tarefas motoras do KTK, demonstrando a importância de considerar uma ponderação na criação de tabelas normativas de avaliações motoras.

ABSTRACT In the last decades, the use of Item Response Theory (IRT) has been implemented due to the complexity of statistical calculations that allows for in-depth analysis of educational tests, questionnaires and lists of items applied in different areas such as psychometry, sports ranking and pedagogy. Based on this premise, this study aimed to verify the suitability of the KTK motor tasks analyzing the degree of difficulty and discrimination parameters of each motor task. A total of 385 children aged 5 to 14 years participated in the study. The instrument evaluated was the KTK (Körperkoordinationstest für Kinder), consisting of four motor tasks: balance beam, single-pedal jumps, side jumps and platform transposition. Analyzes were conducted from the raw data acquired in each motor task. In order to verify the factor structure of the theoretical matrix underlying the test, an exploratory factor analysis was performed, followed by a confirmatory factor analysis. The difficulty and discrimination parameters of each motor task were analyzed using the gradual response model, based on the Item Response Theory (IRT). The results corroborate the factor structure suggested in the original version of the KTK, presenting only one factor, called motor coordination. The AFC indicators were acceptable, indicating good quality of the model adjusted for the sample. It is concluded that the IRT analysis evidenced differences in the parameters of difficulty and discrimination between the KTK motor tasks, demonstrating the importance of considering a weighting in the creation of normative tables of motor assessments.

RESUMO

Abstract Aim: This study investigated the impact of a handball-teaching program through the understanding of the TGfU on motor coordination (MC) and technical skills of students. Methods: The sample consisted of 43 students of both genders, with a mean age of 14.3 years (± 0.46), divided into two groups, G1 - Teaching Games of Understanding (TGfU) and G2 - TGfU + MC, and both received 20 classes. We used the Körperkoordinationstest für Kinder (KTK) for the assessment of MC and the Game Performance Assessment Instrument (GPAI) for technical skills in handball. Results: The categorization confirmed the reliability of the application of teaching programs and the results showed that, after the intervention, both groups presented meaningful improvements in MC, considering time and gender effect. The female students presented a larger impact on MC in both teaching programs, while the male students obtained a larger impact in the technical skill execution index when received the TGfU + MC model. Still, the relative frequency for the classification of a good MC increased in both groups after the intervention, and the normal MC was the one with the highest frequency in both groups and genders after the proposed program. Conclusion: We concluded that the teaching program was able to provide meaningful improvements in MC considering both groups and that the proposal of the inclusion of specific MC elevated the impact of technical skills for male students.

RESUMO

BACKGROUND: Different approaches to reproduce cerebral palsy (CP) in animals, contribute to the knowledge of the pathophysiological mechanism of this disease and provide a basis for the development of intervention strategies. Locomotion and coordination are the main cause of disability in CP, however, few studies highlight the quantitative differences of CP models, on locomotion parameters, considering the methodologies to cause brain lesions in the perinatal period. METHODS: Studies with cerebral palsy animal models that assess locomotion parameters were systematically retrieved from Medline/PubMed, SCOPUS, LILACS, and Web of Science. Methodological evaluation of included studies and quantitative assessment of locomotion parameters were performed after eligibility screening. RESULTS: CP models were induced by hypoxia-ischemia (HI), Prenatal ischemia (PI), lipopolysaccharide inflammation (LPS), intraventricular haemorrhage (IVH), anoxia (A), sensorimotor restriction (SR), and a combination of different models. Overall, 63 studies included in qualitative synthesis showed a moderate quality of evidence. 16 studies were included in the quantitative meta-analysis. Significant reduction was observed in models that combined LPS with HI related to distance traveled (SMD -7.24 95 % CI [-8.98, -5.51], Z = 1.18, p < 0.00001) and LPS with HI or anoxia with sensory-motor restriction (SMD -6.01, 95 % CI [-7.67, -4.35], Z = 7.11), or IVH (SMD -4.91, 95 % CI [-5.84, -3.98], Z = 10.31, p < 0.00001) related to motor coordination. CONCLUSION: The combination of different approaches to reproduce CP in animals causes greater deficits in locomotion and motor coordination from the early stages of life to adulthood. These findings contribute to methodological refinement, reduction, and replacement in animal experimentation, favoring translational purposes.

RESUMO

Resumen La sociedad actual plantea la necesidad de incorporar a la educación aquellas capacidades relacionadas con el cuerpo y su actividad motriz dentro de los márgenes de la salud, pues estas resultan determinantes para el desarrollo integral de la persona. Teniendo esto en cuenta, el objetivo del presente estudio fue analizar la relación entre la condición física global (CF), la coordinación motriz (CM) y la calidad de vida percibida (cvp) en adolescentes españoles. Para esto, se diseñó un estudio descriptivo transversal con 1037 adolescentes de 14 a 16 años de edad, y se utilizó el Cuestionario de salud SF-36 para evaluar la cvp, y la Batería de condición física relacionada con la salud para evaluar la CF global y la CM. Los resultados muestran que los sujetos con mayor CF tuvieron valores promedio más elevados en las variables de función física (p < .001), rol físico (p < .001), vitalidad (p < .05), función social (p < .001), rol emocional (p < .01), salud mental (p < .001) y calidad de vida total (p < .001); mientras que aquellos con menor CF presentaron puntuaciones superiores en dolor corporal (p < .001). Asimismo, los sujetos que mostraron mayor CM obtuvieron mejores registros en salud general, vitalidad, función social y calidad de vida total (p < .001 en todos los casos), y registros inferiores en función física y rol físico (p < .001 en ambos casos). Los resultados de este estudio sugieren que tener una mayor CF, así como una mayor CM, pueden ser variables predictoras de una mejor cvp en adolescentes españoles.

Abstract Today's society poses the need to incorporate into education those capacities related to the body and its motor activity within the margins of health, since these are determining factors for the integral development of the person. Bearing this in mind, the aim of this study was to analyze the relationship between overall physical condition (PC), motor coordination (MC) and perceived quality of life (PQL) in Spanish adolescents. For this purpose, a cross-sectional descriptive study was designed involving 1037 adolescents aged between 14 to 16 years. The SF-36 Health Questionnaire was used to assess the PQL, and the Health-related Physical Condition Battery, to evaluate global PC and MC. The results show that participants with higher PC had higher average values in the variables physical function (p < .001), physical role (p < .001), vitality (p < .05), social function (p < .001), emotional role (p < .01), mental health (p < .001), and total quality of life (p < .001); while those with lower PC had higher scores in body pain (p < .001). Likewise, participants who showed higher MC obtained better records in general health, vitality, social function, and total quality of life (p < .001 in all cases), and lower records in physical function and physical role (p < .001 in both cases). The results of this study suggest that having a higher PC, as well as a higher MC, maybe predictive variables of a better PQL in Spanish adolescents.

RESUMO

AIMS: Homocysteine has been linked to neurodegeneration and motor function impairments. In the present study, we evaluate the effect of chronic mild hyperhomocysteinemia on the motor behavior (motor coordination, functional performance, and muscular force) and biochemical parameters (oxidative stress, energy metabolism, gene expression and/or protein abundance of cytokine related to the inflammatory pathways and acetylcholinesterase) in the striatum and cerebellum of Wistar male rats. MAIN METHODS: Rodents were submitted to one injection of homocysteine (0.03 µmol Hcy/g of body weight) between 30th and 60th postnatal days twice a day. After hyperhomocysteinemia induction, rats were submitted to horizontal ladder walking, beam balance, suspension, and vertical pole tests and/or euthanized to brain dissection for biochemical and molecular assays. KEY FINDINGS: Chronic mild hyperhomocysteinemia did not alter motor function, but induced oxidative stress and impaired mitochondrial complex IV activity in both structures. In the striatum, hyperhomocysteinemia decreased TNF-α gene expression and increased IL-1ß gene expression and acetylcholinesterase activity. In the cerebellum, hyperhomocysteinemia increased gene expression of TNF-α, IL-1ß, IL-10, and TGF-ß, while the acetylcholinesterase activity was decreased. In both structures, hyperhomocysteinemia decreased acetylcholinesterase protein abundance without altering total p-NF-κB, NF-κB, Nrf-2, and cleaved caspase-3. SIGNIFICANCE: Chronic mild hyperhomocysteinemia compromises several biochemical/molecular parameters, signaling pathways, oxidative stress, and chronic inflammation in the striatum and cerebellum of rats without impairing motor function. These alterations may be related to the mechanisms in which hyperhomocysteinemia has been linked to movement disorders later in life and neurodegeneration.

RESUMO

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)

RESUMO

BACKGROUND: Motor coordination, the ability to produce context-dependent organized movements in spatial and temporal domains, is impaired after neurological injuries. Outcome measures assessing coordination mostly quantify endpoint performance variables (ie, temporal qualities of whole arm movement) but not movement quality (ie, trunk and arm joint displacements). OBJECTIVE: To develop an outcome measure to assess coordination of multiple body segments at both endpoint trajectory and movement quality levels, based on observational kinematics, in adults with neurological injuries. METHODS: A 3-phase study was used to develop the Comprehensive Coordination Scale (CCS): instrument development, Delphi process, and focus group meeting. The CCS was constructed from common tests used in clinical practice and research. Rating scales for different behavioral elements were developed to guide analysis. For content validation, 8 experts (ie, neurological clinicians/researchers) answered questionnaires about relevance, comprehension, and feasibility of each test and rating scale. A focus group conducted with 6 of 8 experts obtained consensus on rating scale and instruction wording, and identified gaps. Three additional experts reviewed the revised CCS content to obtain a final version. RESULTS: Experts identified a gap regarding assessment of hand/finger coordination. The CCS final version is composed of 6 complementary tests of coordination: finger-to-nose, arm-trunk, finger, lower extremity, and 2- and 4-limb interlimb coordination. Constructs include spatial and temporal variables totaling 69 points. Higher scores indicate better performance. CONCLUSIONS: The CCS may be an important, understandable and feasible outcome measure to assess spatial and temporal coordination. CCS measurement properties are presented in the companion article.

RESUMO

RESUMO: Este estudo teve como objetivo analisar a lateralidade e a destreza manual em crianças com Transtorno do Espectro Autista (TEA). Do ponto de vista da motricidade humana, a lateralidade contribui para o processo de maturação motora. Figura-se entre as principais características do autismo o atraso nas habilidades motoras grossas e finas, com piora progressiva no quadro. Analisar o nível de lateralidade do indivíduo com TEA torna-se importante por possibilitar uma direção na intervenção motora com o intuito de melhorar a funcionalidade do autista e sua qualidade de vida. A amostra deste estudo foi composta por oito crianças, alunos de uma instituição de ensino pública, do sexo masculino, com idade média de 8,75±1,83 anos e diagnosticadas com TEA com base no DSM-V. Os resultados mostraram que os participantes do estudo parecem apresentar lateralidade destra e, também, melhor desempenho com a mão preferida em uma tarefa de destreza manual. Observou-se que, na tarefa que exigiu maior atenção e destreza, a diferença no desempenho das mãos foi significativa. Já na tarefa com menor demanda atencional e de destreza manual, o desempenho entre as mãos não foi significante, porém foi nesse momento que foram observados os maiores erros na execução. A motivação pode ser uma variável fundamental para o desempenho motor em tarefas que avaliam o tempo de execução. É importante uma maior ênfase no desenvolvimento da motricidade desses indivíduos durante a fase escolar para diminuir as dificuldades motoras e, consequentemente, melhorar a qualidade de vida, sensação de bem-estar, autonomia e interação social.

ABSTRACT: This study aimed to analyze laterality and manual dexterity in children with Autism Spectrum Disorder (ASD). From the point of view of human motor skills, laterality contributes to the motor maturation process. Among the main characteristics of autism is the delay in gross and fine motor skills, with progressive worsening in the condition. Analyzing the level of laterality of the individual with ASD becomes important because it allows a direction in the motor intervention in order to improve the functionality and quality of life of the autistic person. The sample of this study was composed of eight children, students of a public education institution, male, with an average age of 8.75 ± 1.83 years old and diagnosed with ASD based on the DSM-V. The results showed that the study participants seem to have right handedness and also better performance with the preferred hand in a manual dexterity task. It was observed that, in the task that demanded more attention and dexterity, the difference in hand performance was significant. In the task with the lowest attentional demand and manual dexterity, the performance between the hands was not significant; however, it was at that moment that the biggest mistakes in execution were observed. Motivation can be a fundamental variable for motor performance in tasks that assess execution time. It is important to emphasize the development of the motor skills of these individuals during the school phase to reduce motor difficulties and, consequently, improve quality of life, sense of well-being, autonomy and social interaction.

RESUMO

BACKGROUND: Gross motor coordination (GMC) is a potential correlate of lifestyle behaviours and health outcomes in childhood and adolescence. AIMS: The aim of this study was to examine how sex, age, biological maturation, overweight, stunting, and physical fitness are associated with GMC in children and adolescents from Peru, and to examine associations between geographical area of residence, school-level characteristics, and GMC. SUBJECTS AND METHODS: The sample included 7408 subjects, aged 6-14 years, from sea level, Amazon and high-altitude regions of Peru. A composite marker of total coordination was derived by the sum of scores from each test (GMCT). Overweight was identified using BMI, and biological maturation, physical fitness, and stunting were assessed. School characteristics were obtained via an objective audit. RESULTS: Boys (ß = 12.23 ± 0.90) and older children (ß = 13.37 ± 0.64) had higher GMCT than girls and younger children, respectively. Overweight was associated with lower GMCT (ß = -5.23 ± 0.80), whereas fitness was positively associated with GMCT (ß = 6.30 ± 0.25). Biological maturation was not a predictor; however, stunting was negatively associated with GMCT (ß = -3.71 ± 1.56). Subjects living in the Amazon had higher GMCT than those at sea level (ß = 16.57 ± 4.73). Five of nine school-level predictors (number of students, playground area with obstacles, multi-sports roofed, frequency and duration of Physical Education classes) were significant predictors of GMCT. CONCLUSIONS: Child- and school-level variables were significantly associated with GMCT in this sample. These findings are important for the Peruvian community, especially school principals, councils and physical education teachers, helping them to define more efficient strategies and action plans to increase motor coordination in children.

RESUMO

We use a multivariate multilevel model to study the links between physical fitness (PF) and gross motor coordination (GMC) and investigate the influence of predictors affecting their levels across age. We sampled 7918 Peruvians, aged 6-15 years, from sea-level, Amazon region and high-altitude. Composite markers of GMC and PF were derived (GMCz and PFz , respectively). BMI, biological maturation, and stunting were assessed. School characteristics were obtained via an objective audit. School contexts explained 35% of the associations between PFz and GMCz , whereas children's characteristics explained 65% of the total variation. On average, with increasing age, there was a greater increase in GMCz (ß = 0.79 ± 0.04, P < .001) than in PFz (ß = 0.15 ± 0.03, P < .001); boys outperformed girls (PFz , ß = 3.25 ± 0.08, P < .001; GMCz , ß = 1.58 ± 0.09, P < .001); those with lower BMI and ahead in their maturation had higher PFz (ß = -0.13 ± 0.01, P < .001; ß = 1.09 ± 0.05, P < .001, respectively) and GMCz (ß = -0.18 ± 0.01, P < .001; ß = 0.39 ± 0.06, P < .001, respectively) levels. Stunting was negatively related to PFz (ß = -0.30 ± 0.07; P < .001) and GMCz (ß = -0.30 ± 0.08, P < .001) and high-altitude Peruvians had significantly lower GMCz (ß = -0.93 ± 0.33, P < .001), and those living in the Amazon region had significantly higher PFz (ß = 1.21 ± 0.58, P < .001) compared to those living at sea level. A higher number of students was negatively related to PFz (ß = -0.016 ± 0.006, P < .001) and positively with GMCz (ß = 0.005 ± 0.003, P < .001); the duration of physical education classes was positively associated with PFz (ß = 0.70 ± 0.32, P < .001) and GMCz (ß = 0.46 ± 0.15, P < .001); and the existence of policies for physical activity was only negatively associated with GMCz (ß = -1.17 ± 0.34, P < .001). In conclusion, PFz and GMCz were positively correlated and child- and school-level traits predicted their levels.
