Objective. To conduct a bibliometric analysis of scientific production regarding the relative age effect in sport, using data from the PubMed and Scopus databases spanning from January 1, 2015, to April 30, 2023. Methodology. It was based on a descriptive bibliometric analysis of the scientific production having as indicators the following categories: 1) database; 2) year of publication; 3) journal name; 4) journal country; 5) H-index; 6) SCI index (2021); 7) Quartile (Q1; Q2; Q3; Q4); 8); Number of articles per Journal; 9) Scopus citations; 10) Countries evaluated; 11) Colective sports; 12) Individual sports; 13) number of times the sample of a country was evaluated according to journals; 14) Area of knowledge; 15) Gender; 16) Number of authors; 17) Name authors; 18) Instruments used to determine the relative age effect of athletes; 19) Research approach; 20) Research design; 21) Statistical Software packcage; 22) Statistical test; 23) Languaje; 24) Sample Size. The following MeSH terms were used to search for the documents: "Sport", "relative age", "sports performance", and the search equations ("sport competition" AND "relative age effect”), ("sports talent" AND "relative age effect”), ("physical differences" AND "relative age effect”) to search for documents in the Scopus and PubMed databases, obtaining a total of 597 documents. In the end, after applying the criteria, 185 documents were accepted. Results. The number of publications per year has exhibited fluctuating behavior, with 2018 being the year with the highest production (16.09%) and 2016 the lowest (6.32%). In front of the journal, we found those with the most publications, were PloS One with 24 papers (12.97%), Sports with 15 (8.10%), and Journal of Human Kinetics with 13 (7.02%). PloS One (591) and the Journal of Sports Sciences (478) received the highest number of citations. Regarding sports, the ones with the highest number of publications are Soccer with 61 (32.90%), various sports with 24 (12.90%), and basketball with 16 documents (8.64%). Taking into account the countries evaluated, the World Cup (13.008%) and Spain (12.195%) have the highest number of documents. As for the total number of documents by area of knowledge, sports talent (25.40%), sports competition (22.70%), and sports training (15.13%) are the highest. Finally, about gender, it is found that the highest production is about men (74.26%), women-men (20.46%), and women (7.01%). Conclusions. It is concluded that the bibliometric study contributes substantially to the scientific community from the findings found in the study and the change of focus with which relative age has recently been studied. Likewise, it can guide future studies aimed at characterizing and determining the effect of relative age in sports. Key Words: relative age, sport, sports science, sports competition, sports talent

El objetivo del presente estudio fue determinar las relaciones entre la competencia de aprender a aprender, los estilos de vida y la condición física en una muestra de estudiantes universitarios colombianos. Estudio de enfoque cuantitativo y diseño observacional-analítico de alcance transversal. Participaron del estudio 23 estudiantes de primer semestre de la licenciatura en deporte con una edad promedio de 20.48±3.07 años. Para evaluar la competencia aprender a aprender se utilizó el cuestionario CECAPEU, los estilos de vida se midieron a través del cuestionario CEVJU-R2 y para la condición física, se evaluó a través del aplicativo My Jump Lab las siguientes pruebas: SJ, CMJ, CMJB, fuerza isquiotibial, asimetrías, cambio de dirección 5-0-5, velocidad 5, 10 y 15 metros e Illionis, al igual que se tomaron otras pruebas como Sit and Reach, test de equilibrio y Course Navette. Se usó la metodología de análisis factorial múltiple, usando un análisis de inercia para definir el número de componentes a trabajar. Para evaluar la relación entre grupos de variables, así como entre variables y las categorías dentro de estas. El software empleado fue el programa ® versión 4.1.0. Los resultados indican que, existen diversos perfiles que revelan la necesidad de entender que el estudiante que tiene como objeto de estudio al deporte, enfrenta una serie de necesidades asociadas a su estilo de vida y su condición física, lo cual influye en su competencia de aprender a aprender. El estudio permitió reconocer que existen cinco perfilamientos de los estudiantes de primer curso de la licenciatura en Deporte de la Universidad Pedagógica Nacional. Esto puede ayudar a mejorar los programas de intervención y seguimiento de los estudiantes en la carrera, buscando con ello, reconocer que el aprendizaje de estos es diverso y necesita en igual medida, una variabilidad en los enfoques de su enseñanza y, al mismo tiempo espacios que favorezcan un estilo de vida conducente en la mejora de su condición física. Palabras clave: aprendizaje, evaluación, proceso cognitivo, afectividad y sentimiento, formación profesional The aim of this study was to determine the relationships between learning to learn competence, lifestyles and physical fitness in a sample of Colombian university students. The study had a quantitative approach and a cross-sectional observational-analytical design. Twenty-three first-semester undergraduate sports students with an average age of 20.48±3.07 years participated in the study. To evaluate the learning to learn competence, the CECAPEU questionnaire was used, lifestyles were measured through the CEVJU-R2 questionnaire and for physical condition, the following tests were evaluated through the My Jump Lab application: SJ, CMJ, CMJB, hamstring strength, asymmetries, change of direction 5-0-5, speed 5, 10 and 15 meters and Illionis, as well as other tests such as Sit and Reach, balance test and Course Navette. The multiple factorial analysis methodology was used, using an inertia analysis to define the number of components to work on. To evaluate the relationship between groups of variables, as well as between variables and the categories within them. The software used was the program ® version 4.1.0. The results indicate that there are several profiles that reveal the need to understand that the student whose object of study is sport, faces a series of needs associated with their lifestyle and physical condition, which influences their competence to learn to learn. The study made it possible to recognize that there are five profiles of first-year students of the Bachelor's Degree in Sport at the National Pedagogical University. This can help to improve the intervention and follow-up programs for students in the course, seeking to recognize that their learning is diverse and needs, in equal measure, a variability in the teaching approaches and, at the same time, spaces that favor a lifestyle focused on improving their physical condition.

Background/Objectives. The goal of this study was to assess the relative age effect and its relationship with the development of physical abilities and emotional intelligence in Colombian child athletes according to gender and the sport practiced. Methods. A cross-sectional correlational design was used. A total of 135 Colombian soccer and volleyball athletes, 62 boys and 73 girls, voluntarily participated with an average age of 13.25 ± 0.59 years. Physical skills such as SJ, CMJ, CMJA, 5, 10, and 15 m speed, CODS agility, and emotional intelligence were evaluated. Results. Statistically significant differences were found in the mood variables between Q1 and Q4 (p = 0.047, ηp² = 0.08) and Q2 and Q4 (p = 0.035, ηp² = 0.08). These differences are also present in the interpersonal variable between Q1 and Q4 (p = 0.003, ηp² = 0.12), Q2 and Q4 (p = 0.009, ηp² = 0.12), and, finally, in the total emotional quotient between Q1 and Q4 (p = 0.013, ηp² = 0.13), Q2 and Q3 (p = 0.024, ηp² = 0.13), and Q2 and Q4 (p = 0.005, ηp² = 0.13). Conclusions. Based on the findings of this research, it can be concluded that the relative age effect appears to be sensitive to CODS agility, 15 m speed, and SJ power variables concerning gender and sport. Jump height for CMJ concerning gender and CMJA jump concerning sport were considered. Emotional intelligence appears to be a variable sensitive to the relative age effect.
