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.

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.

Junior tennis players travel a lot to play tennis tournaments; this causes them to spend a lot of time away from their homes and disrupts their training, which could reduce their performance and increase the risk of injury. The purpose of this study was to analyze the changes in physical performance and body composition after a six-week international tour in young Chilean female tennis players. Thirty young female tennis players (15.4 ± 0.6) participated in this study. Body weight, skinfolds, and perimeters were measured. Body fat percentage (BFP) and skeletal muscle mass (SMM) were calculated. For physical performance, 5 m sprint, the 505 with stationary start test (505 test), the pro-agility test, countermovement jump (CMJ), and medicine ball throw (MBT) were evaluated. The results show a significant increase in BFP and decrease in SMM (p < 0.01; d = −0.18 and 0.19, respectively). In terms of physical performance, 5 m sprint, the 505 test (p < 0.01; d = −0.95 and −0.95, respectively), CMJ, MBT, and HJ significantly decreased post-tour (p < 0.05; d = 0.96, 0.89 and 0.47, respectively). We conclude that, after a six-week international tour, there were changes in body composition and a significant decrease in 5 m sprint, the 505 test, CMJ, and MBT.

La Diabetes Mellitus tipo 1 (DM1) es una enfermedad crónica, cuyo tratamiento se basa en 4 pilares fundamentales: insulinoterapia, autocontrol, alimentación saludable y actividad física. La literatura sugiere que en diabetes mellitus tipo 2 este último sea de tipo aeróbico, por ser hipoglucemiante, sin embargo, debido a la diferencia de tratamiento en DM1, surge la interrogante en relación a los efectos del ejercicio con predominancia anaeróbica en el control metabólico de una persona con DM1. Objetivo: evaluar el efecto del entrenamiento de Taekwondo W.T.F. sobre el control glucémico de personas con diabetes mellitus tipo 1 de 13 y 14 años de una escuela de Taekwondo en Concepción, Chile, año 2016-2017. Metodología: investigación de enfoque cuantitativo, un diseño descriptivo cuasiexperimental en un grupo, tipo pre-prueba, post-prueba, con un muestreo de tipo no probabilístico. Resultados: El entrenamiento de Taekwondo W.T.F. con predominancia anaeróbica no afectó en forma significativa la variabilidad glucémica pre y post entrenamiento y, generando una disminución de la hemoglobina glucosilada de todos los sujetos intervenidos. Palabras clave: Diabetes Mellitus, Ejercicio, Hemoglobina Glucosilada, Glucemia. Diabetes Mellitus type 1 (DM1) is a chronic disease, whose treatment is based on 4 fundamental pillars: insulin therapy, self-control, healthy eating and physical activity. The literature suggests that diabetes mellitus type 2 is the aerobic type, because it is hypoglycaemic, however due to the difference in treatment in DM1, the question arises in relation to the effects of exercise with anaerobic predominance in the metabolic control of a person with DM1. Objective: to evaluate the effect of Taekwondo training W.T.F. on the glycemic control of people with diabetes mellitus type 1 of 13 and 14 years of a Taekwondo school in Concepción, Chile, 2016-2017. Methodology: quantitative approach research, a Quasi-experimental descriptive design in a group, pre-test type, post-test, with a sampling of non-probabilistic type, Results: Taekwondo training W.T.F. with anaerobic predominance, it did not significantly affect the glycemic variability pre- and post-training and in conjunction with this, it generated a decrease in the glycosylated hemoglobin of all the subjects who underwent surgery.
