Evidence of earthquake-induced liquefaction features in the Acequión river valley, central western Argentina, is analysed. Well-preserved soft-sediment deformation structures are present in Late Pleistocene deposits; they include two large slumps and several sand dikes, convolutions, pseudonodules, faults, dish structures and diapirs in the basal part of a shallow-lacustrine succession in the El Acequión River area. The water-saturated state of these sediments favoured deformation. All structures were studied in a natural trench created as a result of erosion by a tributary of the Acequión River, called El Mono Creek. They form part of a large-scale slump system. Two slumps occur in the western portion of the trench and must have moved towards the ENE (70°), where the depocentre of the Boca del Acequión area is situated. Considering the spatial relationship with Quaternary faults, the slumps are interpreted as being due to a seismic event. The thickest dikes in the El Mono Creek trench occur in the eastern portion of the trench, indicating that the responsible earthquake was located to the east of the study area, probably at the Cerro Salinas fault system zone. The slumps, sand dikes and other soft-sediment deformation features are interpreted as having been triggered by earthquakes, thus providing a preliminary palaeoseismic record of the Cerro Salinas fault system and extending the record of moderate-to high-magnitude earthquakes in central western Argentina to the Late Pleistocene.

La selección y organización de las tareas puede condicionar la carga de entrenamiento. El objetivo de la presente investigación es analizar la relación entre las Variables Pedagógicas Situación de Juego y Nivel de Oposición y las Variables Organizativas y las Variables de Carga Externa. Se analizaron un total de 38 entrenamientos, compuestos por 340 tareas de un equipo de Categoría Cadete durante la temporada 2015/2016. Se realizó además un doble filtrado de datos para eliminar las tareas de calentamiento y tiros libres. En el estudio se obtuvieron resultados descriptivos de todas las variables. Se utilizaron los Coeficientes de correlación de Pearson y Spearman para identificar las relaciones entre las variables. Los resultados muestran la existencia de una relación significativa entre las variables que definen la organización del entrenamiento y las Variables de Carga Externa. La carga del entrenamiento está condicionada por las Variables Organizativas.
