Physical Exercise Methods and Their Effects on Glycemic Control and Body Composition in Adults with Type 2 Diabetes Mellitus (T2DM): A Systematic Review.

The prevalence of T2DM represents a challenge for health agencies due to its high risk of morbidity and mortality. Physical Activity (PA) is one of the fundamental pillars for the treatment of T2DM, so Physical Exercise (PE) programs have been applied to research their effectiveness. The objective of the study was to analyze the effects of PE methods on glycemic control and body composition of adults with T2DM. A systematic review without meta-analysis was performed, using the PubMed database. Quasi-experimental and pure experimental clinical trials were included, which were available free of charge and were published during 2010-2020. In the results, 589 articles were found and 25 passed the inclusion criteria. These were classified and analyzed according to the methods identified (AE, IE, RE, COM, and others), duration and variable(s) studied. It is concluded that PE is effective for glycemic control and body composition in adults with T2DM using different methods (AE, IE, RE, COM, and others), both in the short and long term. Adequate organization of PE components such as frequency, duration, volume, and intensity, is essential.

Effects of Combined Movement and Storytelling Intervention on Fundamental Motor Skills, Language Development and Physical Activity Level in Children Aged 3 to 6 Years: Study Protocol for a Randomized Controlled Trial.

This study protocol aims to analyze and compare the effects of combined movement and storytelling intervention (CMSI) on fundamental motor skills (locomotor skills and object control), language development (language comprehension, language expression, vocabulary and language description), and physical activity levels (light intensity, moderate-to-vigorous intensity and sedentary time) in children aged 3 to 6 years. The sample will consist of 144 children from 12 class groups, randomly assigned to 3 experimental groups (n = 72 children) and 3 control groups (n = 72 children), belonging to 4 class groups of upper-middle-level classes (2 experimental and 2 control; 3 to 4 years), 4 transition level 1 classes (2 experimental and 2 control; 4 to 5 years) and 4 transition level 2 classes (2 experimental and 2 control; 5 to 6 years). The experimental groups will perform CMSI for 3 sessions per week (40 min per session) over 12 weeks (using one motor story per week), while the control groups will not receive any treatment. The main outcome will provide information about fundamental motor skills, language development, and physical activity levels. Our hypothesis indicates that CMSI has the potential to generate significant increases in selected assessments. If this intervention proves to be beneficial, it could contribute to preschool and school curricula.

Association between sleep quality and pain in young amateur athletes / Asociación entre calidad del sueño y dolor en jóvenes atletas amateurs / Associação entre qualidade do sono e dor em jovens atletas amadores

ABSTRACT Introduction: It has been shown that there is a close association between sleep quality and pain. In young athletes, sleep disorders and pain have a particularly high prevalence; however, the relationship between them has not been widely studied. Objective: To study the association between sleep quality and pain in young athletes. Methods: A cross-sectional study was conducted in which 71 young amateur athletes (39 males) were included. The mean age was 16.9 ± 1.2 years, with 6.5 ± 3.2 years of sports practice and 5.2 ± 1.2 hours of training per week. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). The participants were classified according to sleep quality, as PSQI-I = without sleep disorders, PSQI-II = requiring medical assistance and PSQI-III = requiring medical assistance and treatment. Also, pain intensity was assessed on the Numerical Rating Scale, both at rest (NRSr) and during sports activity (NRSs), along with pain duration. Results: The individuals classified as PSQI-III presented higher NRSr (Mdn = 2.0; IQR = 4.0 vs. Mdn = 0.0; IQR = 2.0; p = 0.04) and higher NRSs (Mdn = 4.0; IQR = 5.0 vs. Mdn = 0.0; IQR = 2.0; p = 0.03) than the individuals classified as PSQI-I. No differences were observed in relation to pain duration. The PSQI score was positively but weakly associated with NRSr (rs = 0.24, p=0.046) and NRSs (rs = 0.27, p = 0.03) but not with pain duration. Conclusion: Young athletes with lower levels of sleep quality show higher levels of pain at rest and during sports practice. Therefore, sleep quality and pain should be considered in the routine assessment of young athletes, by technical and health teams. Level of evidence III; type of study: Cross-sectional .

RESUMEN Introducción: Se demostró que existe estrecha relación entre calidad del sueño y dolor. En atletas jóvenes, los disturbios del sueño y dolor tienen prevalencia bastante alta, sin embargo, la relación entre ellos no fue ampliamente estudiada. Objetivo: Estudiar la asociación entre calidad del sueño y dolor en atletas jóvenes. Métodos: Fue realizado un estudio transversal, en el cual fueron incluidos 71 atletas jóvenes amateurs (39 hombres). El promedio de edad fue de 16,9 ± 1,2 años, con 6,5 ± 3,2 años de práctica deportiva y 5,2 ± 1,2 horas de entrenamiento por semana. La calidad del sueño fue evaluada por medio del Índice de Calidad del Sueño de Pittsburgh (PSQI). Los participantes fueron clasificados de acuerdo con la calidad del sueño, PSQI-I= sin disturbios del sueño, PSQI-II= requiere atención médica y PSQI-III= requiere atención médica y tratamiento. Además, la intensidad del dolor fue evaluada en la Escala de Evaluación Numérica en reposo (EANr) y durante la actividad deportiva (EANe), juntamente con la duración del dolor. Resultados: Los individuos clasificados como PSQI-III presentaron mayor valor en el EANr (Mdn = 2,0; IQR = 4,0 vs. Mdn = 0,0; IQR = 2,0; p = 0,04) y EANe mayores (Mdn = 4,0; IQR = 5,0 vs. Mdn = 0,0; IQR = 2,0; p = 0,03) que los individuos clasificados con PSQI-I. No fue observada ninguna diferencia con relación a la duración del dolor. El puntaje del PSQI fue positivo y con débil asociación a EANr (rs = 0,24, p=0.046) y EANe (rs = 0,27, p = 0,03), pero no con la duración del dolor. Conclusión: Los atletas jóvenes con niveles más bajos de calidad del sueño tienen niveles más elevados de dolor en reposo y durante la práctica deportiva. Por lo tanto, la calidad del sueño y el dolor deben ser considerados por los equipos técnicos y de salud en la evaluación rutinaria de atletas jóvenes. Nivel de evidencia III;Tipo de estudio: Transversal.

RESUMO Introdução: Demonstrou-se que existe estreita associação entre qualidade do sono e dor. Em atletas jovens, distúrbios do sono e dor têm prevalência bastante alta, no entanto, a relação entre eles não foi amplamente estudada. Objetivo: Estudar a associação entre qualidade do sono e dor em atletas jovens. Métodos: Foi realizado um estudo transversal, no qual foram incluídos 71 atletas jovens amadores (39 homens). A média de idade foi de 16,9 ± 1,2 anos, com 6,5 ± 3,2 anos de prática esportiva e 5,2 ± 1,2 horas de treinamento por semana. A qualidade do sono foi avaliada por meio do Índice de Qualidade do Sono de Pittsburgh (PSQI). Os participantes foram classificados de acordo com a qualidade do sono, PSQI-I = sem distúrbios do sono, PSQI-II = requer atendimento médico e PSQI-III = requer atendimento médico e tratamento. Além disso, intensidade da dor foi avaliada na Escala de Avaliação Numérica em repouso (EANr) e durante a atividade esportiva (EANe), juntamente com a duração da dor. Resultados: Os indivíduos classificados como PSQI-III apresentaram maior valor no EANr (Mdn = 2,0; IQR = 4,0 vs. Mdn = 0,0; IQR = 2,0; p = 0,04) e EANe maiores (Mdn = 4,0; IQR = 5,0 vs. Mdn = 0,0; IQR = 2,0; p = 0,03) do que os indivíduos classificados com PSQI-I. Nenhuma diferença foi observada com relação à duração da dor. O escore do PSQI foi positivo e com fraca associação a EANr (rs= 0,24, p=0.046) e EANe (rs= 0,27, p = 0,03), mas não com a duração da dor. Conclusão: Atletas jovens com níveis mais baixos de qualidade do sono têm níveis mais elevados de dor em repouso e durante a prática esportiva. Portanto, a qualidade do sono e a dor devem ser consideradas pelas equipes técnicas e de saúde na avaliação rotineira de atletas jovens. Nível de evidência III; Tipo de estudo: Transversal.

Orientaciones Deporte y COVID-19: Recomendaciones sobre el retorno a la actividad física y deportes de niños niñas y adolescentes / Sport COVID-19 Orientations: Recommendations for return to physical activity and sports in children and adolescents

Resumen: La pandemia por COVID-19, originada en diciembre de 2019 en Wuhan, China, obligó a los países, incluido Chile, a un confinamiento masivo para evitar la propagación de SARS-CoV2. Desde marzo de 2020 en Chile, también se afectó la realización de actividad física y deporte en los niños, niñas y adolescentes (NNA). En un esfuerzo por reunir la escasa evidencia disponible sobre el retorno a la práctica de ejercicio en NNA post pandemia COVID-19 y la opinión de expertos de 4 sociedades científicas y académicas (Sociedad Chilena de Medicina del Deporte, Sociedad Chilena de Pediatría, Sociedad Chilena de Kinesiología Deportiva y la Consejo Académico Nacional de Educación Física) se han generado recomendaciones para un retorno seguro a la actividad para el ramo Educación Física y Salud, deporte escolar y federado tanto para disminuir los riesgos asociados a los efectos del confinamiento como para evitar la propagación de COVID-19. Adicionalmente, se incluyen una guía de recomendación para padres y profesores y otra para médicos sobre la vigilancia y evaluación de los pacientes NNA que sostendrán enfermedad COVID-19 y deseen volver al deporte y ejercicio.

Abstract: The COVID-19 pandemic, originated in December 2019 in Wuhan, China, forced a massive quaran tine in most countries including Chile to avoid the propagation of SARS-CoV2. Since March 2020 in Chile, it affected the participation of children and youth athletes as well in education, physical activity and sports. In an effort to assess the scarce available evidence about return to sport and exercise in children and adolescents post COVID-19 pandemic and gather the opinion of experts of 4 Chilean scientific and academic societies (Sociedad Chilena de Medicina del Deporte, Sociedad Chilena de Pediatría, Sociedad Chilena de Kinesiología Deportiva and Consejo Académico Nacional de Edu cación Física) we have produced recommendations for a safe return to activities in Physical Activity and Health class, School Sports and Federation Sports to reduce the risks associated with the effects of confinement and to avoid the propagation of COVID-19 and. Additionally, a recommendation for parents and teachers and a another for physicians for surveillance and evaluation of children and adolescents who were or will become COVID-19 patients and wish to return to sports end exercise.
