The present study aimed to analyze the dynamic and nonlinear association between screen time, executive function (EF), and fundamental motor skills (FMS) in preschoolers, considering sex and body mass index (BMI) from a network perspective. Forty-two preschoolers (24 boys, 3.91 ± 0.77 years old) provided screen time, EF, FMS, and BMI data. EF was measured using the Go/No Go task, and accuracy of Go (sustain attention), reaction time of Go, and accuracy of No Go (inhibitory control) were considered. Relationships between screen time, EF, FMS, sex, and BMI were explored using a network analysis. The emerged network highlights that screen time is intensely associated with the other variables in the network, while the accuracy of Go has the greater connectivity with other nodes in the network (2.27), being the most sensitive to potential intervention changes. Moreover, sex (1.74), screen time (0.93), and accuracy of Go (0.71) showed the greatest closeness. This study showed that in the emerged network, independent of sex, screen exposure affects the accuracy on Go task, and these components affect the variables in the network, as motor abilities and tasks involved in inhibitory control.

The purpose of this study was to investigate the injuries prevalence in men elite artistic gymnasts. Twenty Brazilian senior gymnasts, aged 23.1 ± 6.5 years, 13.9 ± 5.0 years of practice and 36.5 ± 4.7 hours per week training, participated in this study. The athletes answered a morbidity questionnaire, formulated according to studies from the literature, for information on the injuries’ characteristics and circumstances. Information about the injury circumstances (gymnastic apparatus, overload training and physical exercises), the anatomic site injured, the affect biological tissue and the return to training after injury treatment were evaluated. Data were analyzed by descriptive statistics, absolute and relative frequencies. The training overload, and floor, pommel horse and vault were the events that presented higher injuries frequency. In relation to anatomic site, ankle, hands/fingers and shoulder were the most cited regions. The ligament, bone and articular capsule were the most affected biological tissues. In relation to gymnasts’ return to their sports activities, 56% of them reported a better condition at return, 33% reported to have returned at the same fitness level and 10% indicated that they were in a worse condition when they returned to the sports activities. The men’s artistic gymnastics injuries are related to the mechanical demands of this sport. The analysis of risk factors helps in understanding the injuries mechanisms in gymnastics, and provides relevant information that can assist in effective prevention strategies.

Resumo Introdução Intervenções inovadoras são importantes para apoiar melhorias funcionais em crianças com Transtorno do Espectro Autista (TEA). Objetivo Investigar os efeitos de 12 semanas de uma Abordagem Coordenativa em Circuito (ACC) no desempenho cognitivo-motor de crianças com TEA nível 1. Método Participaram do estudo sete crianças do sexo masculino, com idades de 7 a 12 anos. A ACC foi realizada duas vezes por semana, com sessões de 70 minutos. Para as avaliações diagnóstica, atencional e comportamental foram aplicadas, respectivamente, a Escala de Avaliação do Tratamento do Autismo (ATEC), a Escala de Avaliação Swanson, Nolan e Pelham – versão IV (SNAP-IV) e a Escala de Avaliação do Autismo Infantil (CARS). O controle postural foi mensurado por meio de uma plataforma de força, sob condições de olhos abertos (OA) e olhos fechados (OF). Um Circuito Motor Modelo (CMM) foi utilizado para avaliar a coordenação motora. Testes t pareados e equações de estimativa generalizadas foram utilizadas para análise estatística (p < 0,05). Resultados As crianças foram confirmadas dentro do espectro nível 1. Após a intervenção, houve melhora nos escores cognitivo-comportamentais (ATEC) (p = 0,022) e nos escores de desatenção (SNAP-IV) (p = 0,036), enquanto a hiperatividade não apresentou alteração significativa (p = 0,078). Em relação ao equilíbrio, houve redução na área de oscilação do centro de pressão com OF (p = 0,026) e na velocidade média com OA e OF (p < 0,001). Observou-se redução dos erros e do tempo de conclusão (de 3:14 min para 1:18 min) no CMM. Conclusão A intervenção ACC melhorou significativamente o desempenho cognitivo e atencional, a estabilidade postural e a coordenação motora em crianças com TEA nível 1, podendo ser uma estratégia não farmacológica viável e de baixo custo para promover o desenvolvimento funcional nessa população.

Introduction Innovative interventions are important to support functional improvements in children with autism spectrum disorder (ASD). Objective To investigate the effects of 12 weeks of a circuit-based coordinative approach (CCA) on cognitive–motor performance in children with level 1 ASD. Method Seven male children aged 7 to 12 years participated. The CCA was delivered twice weekly in 70-minute sessions. For diagnostic, attentional, and behavioral assessments, the Autism Treatment Evaluation Checklist (ATEC), the Swanson, Nolan and Pelham Rating Scale–IV (SNAP-IV), and the Childhood Autism Rating Scale (CARS) were administered, respectively. Postural control was measured using a force platform under eyes-open (EO) and eyes-closed (EC) conditions. A model motor circuit (MMC) was used to assess motor coordination. Paired t-tests and generalized estimating equations were used for statistical analysis (p < 0.05). Results The children were confirmed as level 1 ASD. After the intervention, improvements were observed in cognitive-behavioral scores (ATEC) (p = 0.022) and inattentiveness scores (SNAP-IV) (p = 0.036), whereas hyperactivity showed no significant change (p = 0.078). Regarding balance, center-of-pressure sway area decreased under EC (p = 0.026), and mean velocity decreased under EO and EC (p < 0.001). Errors and completion time decreased on the MMC (from 3:14 min to 1:18 min). Conclusion The CCA significantly improved cognitive and attentional performance, postural stability, and motor coordination in children with level 1 ASD, and it may represent a feasible, low-cost, nonpharmacological strategy to promote functional development in this population.
