Objective: to validate and adapt the Sedentary Behavior Questionnaire. Materials and methods: content adaptation and validation study, the Delphi technique was used, 18 experts evaluated the items of the questionnaire on a Likert scale regarding their relevance, utility, clarity, written form and length. Results: the questionnaire through its items assesses sedentary activity, the qualitative evaluation showed the need to adapt some questions regarding semantic to the Colombian context, the only item with an alpha lower than 0.70 was 7, the item with the highest Cronbach alpha was 10, the general Cronbach alpha of the instrument was 0.963, which is considered to be of optimal reliability. Conclusions: The content validation process showed that the Sedentary Behavior Questionnaire is a valid instrument in its content that is easy to apply and fill out, it allows a first approach to the sedentary behaviors of the subjects that can be complemented with physical tests to define the level of sedentary lifestyle, the foregoing enables the structuring of promotion and prevention programs by applying an instrument adapted and validated to the Colombian context.

Numerosos entrenadores han utilizado el salto vertical como indicador del rendimiento neuromuscular. En este estudio, se seleccionó de forma no probabilística

Background: Jumping and sprinting are essential skills for several sports, especially for soccer, since they allow to determine neuromuscular function and maximum power of the lower extremities in athletes. This study aimed to establish the relationship between vertical jump performance and sprint speed at 20 m and 50 m in professional soccer players. Methods: This study took place from June 2020 to November 2021 with participants from the U20 category of the Colombian professional team Fortaleza CEIF, and the U18 category of the Brazilian professional team Boston City. The vertical jump was assessed with the countermovement jump (CMJ), squat jump (SJ), and rebound jump (RJ) variants using the WheelerJump jump sensor while the sprint was measured using the Winlaborat horizontal encoder. Results: 200 participants from the selected teams were included in this study. Almost perfect correlations (p < 0,05 – r: 0.97) and excellent coefficients of determination (R 2 : 0.95 – 0.93) were observed between the reactive force index with the mean height of the different jump protocols and the 50-meter sprint speed, indicating that the higher the altitude and/or the higher the reactive force index, the higher the 50-meter sprint speed. The same behavior was found with the 20-meter race, but the correlation levels (p <0,05, r: 0.63-0.62) and the determination coefficients were lower (0.40). Conclusions: The results of this study suggest that, in professional soccer players, long sprint performance like 50 m is strongly correlated and could be accuracy explained by the average height reached in SJ, CMJ, and RJ and by the ability to perform repeated jumps using short contact times, thus increasing the ground reaction forces, which translates into a similar behavior during successive contacts of the player's feet against the ground during the race.

Cancer, particularly breast cancer, is a significant cause of death worldwide, and physical activity has been shown to reduce the risk of developing cancer and improve the prognosis of patients diagnosed with cancer. However, there is a lack of detailed analysis of publications related to physical activity in breast cancer patients, hindering the provision of strong evidence in this area. The Core Collection database of Web of Science (WoS) was used as the source of the bibliography, with a search conducted on October 16, 2023. The search strategy used the terms "Physical Activity" and "Breast Cancer" or "Lymphedema," identifying articles published between 2012 and 2022. The bibliometric analysis focused on three dimensions, including scientific production and delivery, scientific collaboration, and bibliometric evaluation at the individual level. We performed the data analysis with Bibiometrix, an open-source tool integrated with R that allows a complete analysis of the behavior of the scientific literature. A total of 979 publications related to physical activity o exercise in breast cancer (974 article, 1 data paper, 2 article early access y 2 proceedings paper), with an increasing trend in the number of articles published over the years. The most common research topics included “quality of life”, “woman”, “survivors”, and the impact of physical activity on the risk of cancer recurrence. The United States was the most productive country in this area, and the Journal "Supportive Care in Cancer” was the most common journal to publish on this topic. This bibliometric analysis provides insight into publication trends and common research topics in the area of physical activity and breast cancer. The results can be beneficial in guiding future physical rehabilitation research inquiries and providing information to funding agencies on areas of greatest research opportunities.

En América y Europa, la mayoría de los niños y adolescentes no alcanzan las recomendaciones de actividad física de la OMS. La alfabetización física, que abarca habilidades y disposición para la actividad física, es fundamental para el desarrollo integral. Este estudio realizó una revisión exploratoria para describir los procesos de validación de la segunda versión del CAPL-2 en escolares de 8 a 12 años. Se identificaron 39 artículos en bases de datos, de los cuales 7 cumplieron los criterios de inclusión. Los estudios mostraron variabilidad en los procesos de validación del CAPL-2, con algunos realizando validaciones completas y otros solo de los cuestionarios. Las muestras variaron de 57 a más de 300 participantes, y solo dos estudios mencionaron la aleatorización. La mayoría de los estudios se realizaron en Europa y Asia, con una notable falta de investigaciones en Latinoamérica y Centroamérica. Aunque los hallazgos respaldan la fiabilidad y validez del CAPL-2, se destaca la necesidad de considerar contextos específicos al seleccionar herramientas de evaluación. La escasez de datos en regiones como Latinoamérica subraya una brecha significativa en la investigación sobre alfabetización física en estos contextos culturales y socioeconómicos. Palabras claves: Alfabetización física, Validación, Inactividad física, Contexto cultural In America and Europe, most children and adolescents do not meet the WHO's physical activity recommendations. Physical literacy, which encompasses skills and willingness for physical activity, is crucial for holistic development. This study conducted an exploratory review to describe the validation processes of the second version of CAPL-2 in children aged 8 to 12 years. A literature search in databases identified 39 articles, of which 7 met the inclusion criteria. The reviewed studies showed variability in CAPL-2 validation processes, with some conducting full validations and others only validating the instrument's questionnaires. Sample sizes ranged from 57 to over 300 participants, and only two studies mentioned randomization. Most studies were conducted in Europe and Asia, highlighting a lack of research in Latin America and Central America. While the findings support the reliability and validity of CAPL-2, they underscore the need to consider specific contexts when selecting assessment tools. The scarcity of data in regions such as Latin America reveals a significant gap in research on physical literacy in these cultural and socioeconomic settings.

Introducción: En el taekwondo, al igual que en muchos deportes, los deportistas con ciertas características físicas o fisiológicas tienen ventaja sobre sus adversarios; por lo anterior, aquellos deportistas que presenten algunas características antropométricas favorables tendrán un mejor rendimiento en la práctica del taekwondo. Objetivo: Revisar y caracterizar el somatotipo de los atletas que practican el taekwondo según categoría y sexo. Materiales y métodos: Revisión en la literatura utilizando criterios de búsqueda prestablecidos con operadores boleanos (“taekwondo” OR “karate” OR “martial arts” OR “judo” OR “mixed martial arts”) AND (“somatotype” OR “body composition” OR “anthropometry”). Se obtuvieron 15 artículos de tipo descriptivo-observacional que se incluyeron en el análisis. Resultados: La muestra total suma 826 atletas, con una edad media de 20,4 ± 1,76 años. Se evidenciaron valores somatotípicos variados según el nivel competitivo, el país y la categoría de peso; sin embargo, se observa cierta prevalencia del componente mesomórfico y ectomórfico en varones. En contraste, para el sexo femenino, aunque se encontraron menos trabajos para analizar, se evidenció una tendencia hacia una clasificación somatotípica central. Conclusión: El somatotipo es tan solo uno de los muchos factores a la hora analizar a un deportista o a un grupo de atletas, pero este puede ser el punto de partida para poder identificar posibles talentos en este deporte.
