El fútbol como deporte demanda una serie de situaciones donde la fuerza explosiva es determinante. El objetivo de la presente investigación fue determinar los efectos que se generan sobre la fuerza explosiva del tren inferior al aplicar un programa de entrenamiento basado en el método pliométrico, en jugadores de fútbol entre 17 y 18 años de la Academia Iguarán Fútbol Club, según su posicionamiento dentro del campo de juego. El estudio incluyó 32 jugadores, agrupados en grupo control (n:16) y grupo experimental (n:16), los cuales fueron asociados por posición, defensas centrales (DC n=6), defensas laterales (DL n=6), volantes (VOL n=12) y delanteros (DEL n=8). El estudio tuvo un enfoque cuantitativo, de tipo descriptivo y diseño cuasiexperimental. El tratamiento estadístico fue realizado mediante el software estadístico ® versión 4.1.0. Los resultados demuestran que, la capacidad de salto refleja diferencias entre las posiciones, para los volantes se presentaron diferencias significativas (p=0.03) sobre las variables de tiempo de vuelo, altura de salto y picos de velocidad, ubicándose muy cerca a estos valores, los delanteros. Esto puede responder a las exigencias y/o requerimientos específicos del posicionamiento de juego, principalmente, para el desarrollo de acciones donde la fuerza es un actor protagónico. El tiempo de aplicación del programa de pliometría, genera diferentes adaptaciones a nivel muscular, teniendo en cuenta que los datos obtenidos para las diferentes posiciones reflejaron que en algunas posiciones se evidencian cambios sobre variables como la altura y la velocidad, mientras que en otras se presentan cambios sobre la fuerza y potencia. Palabras clave: fútbol, evaluación, adolescencia, método de medición. Abstract, Soccer as a sport demands a series of situations where explosive strength is determinant. The objective of the present research was to determine the effects generated on the explosive strength of the lower body when applying a training program based on the plyometric method, in soccer players between 17 and 18 years old of the Academia Iguarán Fútbol Club, according to their positioning within the field of play. The study included 32 players, grouped in control group (n:16) and experimental group (n:16), which were associated by position, central defenders (DC n=6), lateral defenders (DL n=6), midfielders (VOL n=12) and forwards (DEL n=8). The study had a quantitative approach, descriptive and quasi-experimental design. The statistical treatment was performed using the statistical software ® version 4.1.0. The results show that the jumping capacity reflects differences between positions, for the flyers there were significant differences (p=0.03) on the variables of flight time, jumping height and speed peaks, with the forwards being very close to these values. This may respond to the demands and/or specific requirements of the game positioning, mainly for the development of actions where strength is a protagonist. The application time of the plyometric program generates different adaptations at a muscular level, taking into account that the data obtained for the different positions showed that in some positions changes are evidenced on variables such as height and speed, while in others there are changes on strength and power. Keywords: soccer, assessment, adolescence, measurement method.

Los procesos de caracterización del fútbol femenino son necesarios en distintos grupos de edad para conocer cuáles son los requerimientos según cada posición del juego en busca de favorecer el desarrollo del fútbol femenino. El objetivo del presente estudio fue determinar las diferencias morfofuncionales de las jugadoras de fútbol femenino bogotano en atención a su posición de juego. El estudio incluyo 81 jugadoras con una edad promedio de 15,58±0,85 años, una talla de 159,4±5,36 cm y una masa corporal de 54,55±6,82 kg, agrupadas en seis posiciones: portera (P, n:8), defensa central (DC, n:13), defensa lateral (DL, n:14), volante central (VC, n:18), volante lateral (VL, n:11) y delantera (DEL, n:17) a partir del análisis de variables morfofuncionales (somatotipo, resistencia, velocidad y fuerza). El estudio es de enfoque cuantitativo, no experimental y diseño descriptivo, con un muestreo no probabilístico. El tratamiento estadístico fue realizado mediante el software estadístico R versión 4.1.0. Los resultados indican que, entre las diversas posiciones existen diferencias significativas entre variables relacionadas con el peso (p=0.03), la masa libre de grasa (p=0.01), la fuerza neta (FN) en pierna derecha 100ms [N] (p=0.04), FN pierna derecha 150ms [N] (p=0.03), FN pierna derecha 200ms [N] (p=0.03), promedio de habilidad de sprint repetido (RSA) (p=0.00) y porcentaje de fatiga (p=0.00). Estos resultados mostraron que, entre las distintas posiciones se encuentran diferencias significativas, lo que puede deberse a las demandas y exigencias de la competencia en respuesta a la especificidad de la posición. The processes of characterization of women's soccer are necessary in different age groups to know what are the requirements according to each playing position in order to favor the development of women's soccer. The objective of the present study was to determine the morpho-functional differences of women's soccer players in Bogota according to their playing position. The study included 81 players with an average age of 15.58±0.85 years, a height of 159.4±5.36 cm and a body mass of 54.55±6.82 kg, grouped in six positions: goalkeeper (P, n:8), central defense (DC, n:13), lateral defense (DL, n:14), central midfielder (VC, n:18), lateral midfielder (VL, n:11) and forward (DEL, n:17) based on the analysis of morpho-functional variables (somatotype, endurance, speed and strength). The study has a quantitative approach, non-experimental and descriptive design, with non-probabilistic sampling. The statistical treatment was performed using R statistical software version 4.1.0. The results indicate that, among the different positions there are significant differences between variables related to weight (p=0.03), fat-free mass (p=0. 01), net force (FN) in right leg 100ms [N] (p=0.04), FN right leg 150ms [N] (p=0.03), FN right leg 200ms [N] (p=0.03), average repeated sprint ability (RSA) (p=0.00) and fatigue percentage (p=0.00). These results showed that, among the different positions, significant differences are found, which may be due to the demands and requirements of the competition in response to position specificity.

Background/Objectives: Various studies have investigated the importance of perceptual–cognitive skills in decision-making and the expert performance of athletes. However, bibliometric study has yet to identify research trends on this topic. The objective of this study was to perform a bibliometric review to identify the research trends in the study of soccer decision-making. Method. A total of 172 studies were included in the databases. Results. The year 2021 was the year with the highest number of published studies (n = 23), and 2016 was the year with the highest number of citations (n = 692). The average number of citations per document was 19.79. The concepts that have the greatest occurrence in the investigations are performance (n = 68), decision-making (n = 54), expertise (n = 32), skill (n = 23), and anticipation (n = 22). The journals with the highest number of published documents are the Journal of Sport Sciences (10 documents and 437 citations) and PLoS One (11 documents and 349 citations). The countries with the highest number of published documents and citations are England (n = 46 documents and 996 citations), Germany (n = 32 documents and 749 citations), and Spain (n = 38 documents and 597 citations). German Sport University Cologne is the organization that has the most publications and citations (n = 19 and 531). Conclusions. Existing knowledge production on decision-making in soccer has a preference for the study of two major categories: one related to the analysis of the factors associated with perceptual–cognitive skills, mental fatigue, anticipation, creativity, and memory, whereas the second is more related to the study that has decision-making in the manifestations of specific game performance, between experts and novices, in the precision of technical actions, such as the pass, as well as in a methodology for the selection of athletes.
