Possession Zone as a Performance Indicator in Football. The Game of the Best Teams

2017

Possession time in football has been widely discussed in research but few studies have analyzed the importance of the field area in which possession occurs. The objective of this study was to identify the existence of significant differences in the field zone of ball possession between successful and unsuccessful teams and to acknowledge if the match status modulates the possession model. To this end, 2,284 attacks were analyzed corresponding to the matches in the final phase of the UEFA Euro 2016 France, recording possession time and field zone in which possession occurred. Video recordings of matches were analyzed and coded post-event using notational analysis. We have found that successf…

Possession in Football: More Than a Quantitative Aspect – A Mixed Method Study

2019

The aim of the present study was to identify and differentiate the factors that determine the possession times of successful and unsuccessful elite football teams, with the purpose of identifying a more effective possession model. For this, match corresponding to the round of eighth-finals, quarter-finals, semi-finals and final of the 2016 UEFA Euro France in which 2,636 offensive sequences occurred, were analyzed. Video recordings of matches were analyzed and coded post-event using systematic observation. The performance indicators recorded and analyzed were: phase; match period; type of start-up; interaction context; intention; field zone; possession time, passes, attack outcome; match st…

Structural control on the presence and character of calas: Observations from Balearic Islands limestones rock coast macroforms

2013

Calas are characteristic embayed rocky coastline landforms related to steep-sided drowned valleys that were deeply incised during low sea-level stages into carbonate plateaus. This paper studies the factors that control the presence and character of calas in three different islands of the Balearic Archipelago (Mallorca, Menorca and Formentera) by means of Digital Elevation Model (DEM) reconstructions, embayment and catchment morphometric analysis and through the compilation of fault and joint orientations. All islands exhibit emerged carbonate platforms (Upper Miocene in age) characterised by horizontal or very gently-dipping bedding. Two distinct patterns observed at all study sites are th…

Effects of an experimental short-time high-intensity warm-up on explosive muscle strength performance in soccer players: A pilot study.

2022

Objective: This study aimed to evaluate the effects of an experimental short-time warm-up consisting of a small number of intermittent high-intensity sprints on explosive muscle strength performance in soccer players and to identify recovery times after performing the sprints. Furthermore, we evaluated the reliability of a smartphone app in jumping performance.Methods: Twenty male soccer players were given the following tests: 1) the counter-movement jump (CMJ) test with the Microgate system, 2) the counter-movement jump (CMJ) test with the MyJump smartphone app, and 3) the handgrip strength test. The experimental short-time high-intensity warm-up was carried out 1 week after test administr…

Sports injuries in Finnish elite cross-country skiers, swimmers, long-distance runners and soccer players

2011

In sports with different exercise-loading characteristics, acute and overuse injury profiles and gender differences in injuries were investigated. In addition, trainingrelated risk factors for overuse injuries in endurance athletes were studied. This twelve-month retrospective questionnaire study comprised Finnish elite crosscountry skiers (n=149), swimmers (n=154), long-distance runners (n=143) and soccer players (n=128) aged 15–35 years. Questionnaires were sent to the athletes in each sports at the end of the 2006 competition season. Athletes who ended their sports career because of injury were studied in more detail by means of a telephone interview (n=20) 7-11 months after the question…

Lactacidemia en el umbral anaeróbico. Estudio en varones prepúberes de escuelas deportivas de fútbol.

2004

El objetivo principal es conocer la conducta del lactato en sangre.Situación bibliográfica.Estructurada en cinco apartados: reservas energéticas y límites metabólicos, la regulación ácido-base, el metabolismo del lactato, el umbral anaeróbico y las diferencias existentes entre niños y adultos. Nos centramos en los menores niveles de lacticemia en los niños, el mayor umbral anaeróbico en prepúberes frente a adultos y las diferencias de adaptación del metabolismo glucolítico.Material y métodos. Los criterios de selección de la población estudiada fueron: varones de 8-12 años, nivel socioeconómico medio, raza blanca, ausencia de limitaciones patológicas, volumen testicular menor o igual a 3 ml…

Unipedal vertical jumping performance in soccer players

2011

Introduction: The muscular strength between the dominant and non-dominant legs of soccer players has been the centre of research that has highlighted contradictory results. Several researchers have reported symmetry between the dominant and non-dominant legs, whereas others suggest the existence of a significant asymmetry. Kicking and cutting skills in soccer are clearly unilateral, require asymmetrical motor patterns and can lead to the development of asymmetrical adaptations in the musculoskeletal function of the lower limbs (Fousekis et al., 2010). The purpose of this study was to examine the flight time [FT] and jump height [JH] during a vertical one-legged countermovement jump by domin…

Relative age and perceptions of soccer specific skills among elite youth players in Norway

2019

One common feature among the selected players in talent development programs are the well-known relative age effect (RAE), characterized by a skewed birth distribution among selected players with an over-representation of players born early in the selection year. The aim of the present study was to examine potential differences in soccer-specific skills between players selected for national talent program born in the first half of the year compared to the players born in the second half of the year. A total of 753 elite male U 14 (N = 363) and U 13 players (N = 390) from 16 of 18 soccer regions in Norway participated. The results showed players born early in the selection year considered th…
