Juegos Reducidos en Rugby: diferencias entre el uso o no de contactos y distintos espacios de interacción. [Small-Sided Games in Rugby: Differences between the use or not of contact and different spaces of interaction].

Abstract

El objetivo de este estudio fue comparar los patrones de movimiento y la intensidad del ejercicio en series de juegos reducidos (JR) manipulando el tamaño del espacio y la presencia o no de contacto. 10 jugadoras de un equipo de rugby siete femenino fueron monitorizadas mediante un GPS para medir los patrones de movimiento, y con un pulsómetro para medir la Frecuencia Cardiaca. Se registraron datos de  4 entrenamientos, en los que se proponían distintas medidas de JR (32x24m y 64x48m) y la inclusión o no de contacto, en los que cada equipo estaba integrado por 5 jugadoras. Cada formato de juego se distribuyó en dos series de 8 minutos con un descanso pasivo de 5 minutos entre cada serie. Los resultados mostraron que las jugadoras recorrieron más carrera a alta velocidad cuando jugaron con contacto, aunque solo en el espacio grande (Diferencia sustancial; TE ± 90% LC); y que cuando los JR se ejecutaron en espacios grandes, las jugadoras se vieron sometidas a unos patrones de movimiento más exigentes, indistintamente de jugar con o sin contactos.

Abstract

The main goal of this study was to compare patterns of movement and exercise intensity in series of small-sided games (SSG), manipulating the pitch-size and the presence or absence of physical contact. Ten female rugby seven players participated wore a GPS unit to asses patterns of movement and a heart rate monitor to measure heart rate during the series. Data from four training sessions were registered, in which different measures of SSG (32x24m y 64x48m) and the presence or not of contact were developed. Each team was composed of five players. Each game format was distributed in two series of eight minutes, with two rest minutes between each of them. Results showed that players run more at high speed when they played with contact, but only in the large space (substantial difference; ES ± 90% CL), and when small-sided games were executed in large spaces, players were subjected to more demanding patterns of movement, without distinction of playing with or without contacts.
