“…Los resultados de los metros recorridos por minuto en C1 y C2 son semejantes a los obtenidos por otros estudios de SSG en condiciones similares al presente estudio (Casamichana, San Ramón-Quintana, Castellano & Calleja-González, Esta obra está bajo una Licencia Creative Commons Atribución-NoComercial-CompartirIgual 4.0 Internacional 2012, , Casamichana, Castellano & Hernández-Mendo, 2014Hill-Haas, Rowsell, Dawson & Coutts, 2009;Rampinini et al, 2007).…”

“…En cuanto a los datos fisiológicos, se obtuvieron diferencias significativamente mayores en C1 en comparación con C2, similares a Casamichana et al (2014) y Casamichana et al (2011. Estos resultados están en contraposición con los mencionados por Kelly y Drust (2009), quienes indicaron que la frecuencia cardiaca no varió significativamente al ejecutar SSG en diferentes dimensiones de terreno (600 m 2 , 1200 m 2 y 2500 m 2 ).…”

El propósito de esta investigación fue comparar las demandas cinemáticas en dos tipos de dimensiones de juego en jugadores de fútbol universitario costarricenses. 14 jugadores universitarios de fútbol de Costa Rica jugaron dos juegos en campo reducido (SSG) (2x10min, 3min de descanso): C1 (600m2) y C2 (1200 m2). Se utilizó un Sistema de Posicionamiento Global para medir las variables cinemáticas y fisiológicas en ambas condiciones. Se utilizó un ANOVA mixto; los resultados sugirieron que C1 y C2 fueron estadísticamente diferentes en velocidad (C1 <C2), distancia (C1 <C2) y frecuencia cardíaca (C1> C2). Al analizar la distancia recorrida por la categoría de velocidad; en acciones de carrera baja, moderada y alta intensidad, los resultados sugieren que C2 posee mayores intensidades en comparación con C1. Esta investigación confirma los resultados de estudios previos sobre la efectividad de SSG para simular condiciones de juego real en períodos cortos de tiempo. Conclusiones: El C2 presentó una mayor intensidad en comparación con el juego C1 con menores demandas fisiológicas. Asimismo, el C2 refleja de manera más exacta las condiciones en partidos oficiales de jugadores costarricenses.

“…For this reason, it would be advisable that future studies extend the sample to different player's level, category and experience. The gender variable should also be considered, since Garcia, Argudo & Alonso (2012) appreciate differences between two groups, the coach's performance and communication during practice (Calpe, Guzmán & Grijalbo, 2013) the play of field dimensions (Casamichana, Castellano & Hernández-Mendo, 2014). On the other hand, it should be considered to analyze the existence of differences in the variables analyzed (goal, failure and interception) in the resolution of playing micro-situations of real competition in SNTI.…”

This study tries to validate a teaching protocol of playing micro-situations in simple temporary numerical inequality in water polo. 20 theoretical and practical sessions were designed and applied on the appropriate actions to be taken. Observational methodology was used through a descriptive and correlational longitudinal design. The differences between an experimental group and a control group were analyzed in 160 playing micro-situations in relation to goal achievement, failure, interception and duration. There were significant differences between groups (χ²(2)=16.99, p<.001; TE=.23), finding more goals and fewer interceptions in the experimental group. Likewise, there is no statistical significance when analyzing the influence exerted by the start field position in the experimental group, which if observed in control group, who receives more goals from the left wing and more interceptions from the left flat. Finally, there are more failures in control group considering the 3:3 game system. It is concluded that the protocol used with the experimental group is valid, reliable and it is recommended its application in teaching process to facilitate understanding the game dynamics. Experimental analysis of a protocol for teaching simple temporary numerical inequality in U14 water polo players.

“…Small-sided games were also played for 8 minutes, with a pitch size of 736m 2 (activity based on Casamichana, Castellano, and Hernández, 2009), in order to analyze soccer techniques, such as goals, passes, and shots on goal of two teams on both types of surfaces. Small-sided games simulate, totally or partially, a soccer match, and are considered a highly valuable strategy to improve soccer players' performance (Sánchez, Yagüe, Fernández, and Petisco, 2014).…”

The purpose of this study was to compare the effect of artificial turf (AT) and natural grass (NG) on the physical and technical performance of professional soccer players. A total of 17 healthy male soccer players (24.0 ± 4.1 years, height 174 ± 6.1 cm; body weight 73.4 ± 6.3 kg; body fat % 14.2 ± 2.3; VO2max 55.5 ± 5.3 ml/kg/min) from a Costa Rican Professional Soccer League club were subjected to different tests in both types of surfaces (technical test, agility test, repeated sprint ability test, and a small-sided game [8 minutes, 32 x 32 meters, 5 vs. 5]). Players were monitored using a GPS in two sessions, separated by 48 hours, during the club's pre-season. There were no significant differences between the two types of surfaces for the technical, agility, and repeated sprint ability tests. The physiological and kinematic variables analyzed during the small-sided game presented significant differences in average heart rate (NG = 168.5 ± 8.8, AT = 154.8 ± 11.8, p <.001), maximum heart rate (NG = 183.2 ± 8.3, AT = 175.9 ± 10.4, p =.02), body load (NG = 34.3 ± 11.2, AT = 30.5 ± 11.4, p =.03), and total impacts (NG = 230.1 ± 89.5, AT = 194. 8 ± 86.4, p=.03). It is concluded that playing on the natural grass surface caused more impact on physiological and perceived body load in players. In the case of technical variables, it is concluded that there were no statistically significant differences between the two types of surfaces (p <0.05).Keywords: soccer, physical tests, exercise, training.Juan Carlos Ávalos-Guillén , Randall Gutiérrez-Vargas, Gerardo Araya-Vargas, Braulio ResumenEl propósito de este estudio fue comparar el efecto de la superficie artificial (AT) y la natural (NG) sobre el desempeño físico y técnico de los jugadores profesionales de fútbol. Un total de 17 jugadores de fútbol en buen estado de salud (24.0 ± 4.1 años, peso 174 ± 6.1 cm; peso corporal 73.4 ± 6.3 kg; porcentaje de grasa corporal 14.2 ± 2.3; VO2max 55.5 ± 5.3 ml/kg/min) de una liga profesional de fútbol de Costa Rica realizaron diferentes pruebas en ambas superficies (prueba técnica, agilidad, sprints repetidos y juego en espacio reducido [8 min, 32x32 m, 5 vs. 5]). Los jugadores se monitorearon con un GPS en dos sesiones, las cuales estuvieron separadas por 48 horas, durante la pretemporada del club. No se encontraron diferencias significativas entre ambas superficies de juego en cuanto a desempeño técnico, agilidad y sprints repetidos. Existieron diferencias significativas en las variables fisiológicas y cinemáticas analizadas durante el juego en espacio reducido en cuanto a frecuencia cardiaca promedio (NG = 168.5 ± 8.8, AT = 154.8 ± 11.8, p <.001), frecuencia cardiaca máxima (NG = 183.2 ± 8.3, AT = 175.9 ± 10.4, p =.02), carga corporal (NG = 34.3 ± 11.2, AT = 30.5 ± 11.4, p =.03) e impactos totales (NG = 230.1 ± 89.5, AT = 194. 8 ± 86.4, p=.03). Se concluye que practicar en terreno natural ocasiona mayor impacto en los jugadores en cuanto a la carga corporal y fisiológica. En el caso de las variables técnicas, se conc...
