Effect of the Game Design, the Goal Type and the Number of Players on Intensity of Play in Small-Sided Soccer Games in Youth Elite Players
Abstract The aim of this study was to compare the effects of game design modification, the type of the goal and the number of players on the intensity of play in small-sided soccer games (SSGs) in youth elite players. Twenty young soccer players (age 13.7 ± 0.5 years, body mass 57.4 ± 7.8 kg, body height 1.67 ± 7.8 m, maximal heart rate 201.1 ± 8.2 beats/min) performed three types of SSGs (possession play (PP) vs. regular goals (RG) vs. small goals (SG)) in both four-a-side and six-a-side formats. The heart rate responses were recorded and analysed as an indicator of the intensity of play. The four-a-side format obtained higher intensity of play than six-a-side for PP (p<0.05), but not f…

Playing tactics, contextual variables and offensive effectiveness in English Premier League soccer matches. A multilevel analysis.
The aim of this study was to investigate the combined effects of tactical and contextual indicators on achieving offensive penetration and scoring opportunities in English Premier League (EPL) soccer matches. A total of 1971 team possessions from 20 random matches were evaluated by means of multidimensional observation. The EPL matches had a great proportion of fast attacks (36.0%) followed by combinative (29.6%), direct attacks (24.1%) and counterattacks (9.5%). Multilevel logistic regression models revealed that counterattacks (OR = 3.428; 95% CI: 2.004–5.864; P<0.001) were more effective to create goal scoring opportunities than combinative attacks, while direct attacks showed to be less…
Creación de ocasiones de gol en fútbol de élite. Diferencias tácticas entre Real Madrid CF y FC Barcelona (Creating goal scoring opportunities in elite soccer. Tactical differences between Real Madrid CF and FC Barcelona)
El objetivo de este estudio fue comparar los indicadores tácticos utilizados en la creación de ocasiones de gol entre Real Madrid C.F. (RMCF) y F.C. Barcelona (FCB). Todas las posesiones finalizadas en ocasión de gol (n=945) durante 64 partidos (32 por equipo) de la Liga BBVA 2011-2012 fueron analizadas a través de observación sistemática. Las posesiones fueron agrupadas según el tipo de inicio en “recuperaciones” (n=526), “reanudaciones” (n=199), y “acciones a balón parado” (n=175). 9 dimensiones relacionadas con indicadores tácticos fueron analizadas utilizando análisis chicuadrado. En recuperaciones, RMCF registro más penetración inicial (p<0.01), mayor porcentaje de contraataques (p&…
Effect of Match Location, Team Ranking, Match Status and Tactical Dimensions on the Offensive Performance in Spanish ‘La Liga’ Soccer Matches
The aim of this paper was to study the combined effects of tactical and contextual dimensions on achieving offensive performance in open play possessions from Spanish “La Liga” soccer matches. 1860 team possessions from 20 random matches were evaluated by means of multidimensional observation. Multilevel regression models were constructed to predict the probability to achieve offensive performance according to the tactical and contextual dimensions registered in each possession. Performing penetrative actions after recovering the ball (OR = 1.497; 95% CI: 1.022–2.192; P < 0.05), and progressing by fast attacks (OR = 3.588; 95% CI: 2.045–6.294; p < 0.001) or counterattacks (OR = 7.097;…
Technical, tactical and spatial indicators related to goal scoring in European elite soccer
The aim of this study was to describe the technical, tactical and spatial indicators related to goal scoring in elite European soccer, considering the type of defence and the positioning of the opponent. For the analysis, 8 tactical dimensions related to the final actions in 380 sequences that led to goal during the UEFA Champions League were evaluated by observational methodology. 75.9% of the goals were scored from open play and 24.1% were scored from set pieces. Collective actions produced 51.6% of the total goals while individual actions produced 10.5% of goals. Regarding the penultimate action, crosses were more frequent against organized defences, while passes in behind the defence, o…
'REOFUT' as an Observation Tool for Tactical Analysis on Offensive Performance in Soccer: Mixed Method Perspective
Performance analysis in complex sports like soccer requires the study of the influence of the interaction between both teams during the game on final performance. The mixed methods approach involves the collection, analysis, and interpretation of qualitative and quantitative data for the same purpose and within the framework of the same study. To build certain observation tools, mixed methods are necessary in order to take advantage of integration between qualitative and quantitative elements. The aim of this study was to develop a new no standard observation tool to analyze soccer offensive performance considering not only the observed team but also some aspects of the opponent behavior, a…
The effect of contextual variables on the attacking style of play in professional soccer
The aim of this paper was to investigate the interactive effects of contextual variables on the attacking style of play in professional soccer. 5849 team possessions from 40 random matches from Spanish La Liga and English Premier League 2017-2018 were analysed by means of multidimensional observation. Multilevel multivariate logistic regressions showed that home teams had higher odds of implementing fast attacks (p<.05) and lower odds of implementing direct attacks (p<.05) than combinative attacks. High-ranked teams presented lower odds of using direct attacks (p<.05) than combinative attacks in comparison with low-ranked teams, while playing against high-ranked opponents decreased the prob…
Minimal Stabilization Time for Ultra-short Heart Rate Variability Measurements in Professional Soccer
The main aims of this study were: 1) to compare 1-minute RMSSD measurements using different stabilization times between them and also with the criterion; and 2) to determine the agreement between every 1-minute RMSSD measurement with the criterion in professional soccer players. Seven hundred eighteen HRV measurements from professional soccer players were taken. HRV was calculated from 5 to 10 minutes (criterion) and from 1-minute windows with different pre-stabilization times. Friedman and post-hoc tests were applied to compare 1-minute and criterion measurements. Effect size was considered to describe magnitude of change. To determine agreement, Spearman’s correlation was applied, and Bla…
Different Pitch Configurations Constrain the Playing Tactics and the Creation of Goal Scoring Opportunities during Small Sided Games in Youth Soccer Players
The aim of this study was to explore the tactical effects of different pitch configurations on the collective playing tactics and the creation of goal scoring opportunities (GSO) during small sided soccer games (SSG) in youth players. A total of 22 players performed a 7 vs. 7 + 1 floater (including goalkeepers) under three different pitch configurations (“Standard”, 53 × 38 m
