Abstract:Previous studies investigating running distance in high performance soccer have led to contradictory evidence, potentially due to ignoring contextual information during match phases. The present study therefore examined the relationship between running performance and goal scoring in a football match for a standardised score line. In a sample of 302 matches from the first German Bundesliga, the first goal was modelled as a function of the teams’ running performance and team strength using logistic regression. … Show more
“…For example, physical actions can be performed in situations such as Break into Box, Over/Underlap and Run with Ball (Ju et al, 2021). This result can motivate the performance of a more significant number of physical actions (Castellano et al, 2011;Buchheit et al, 2018;Klemp et al, 2021).…”
The current brief research report aimed to investigate the influence of contextual variables on peak running performance in male elite soccer players. We analyzed 29 matches of an elite soccer team during the Brazilian Serie A 2019. Twenty players were tracked using GPS units. Peak physical performance was determined using moving average running values with different time windows (1, 3, and 5-min periods). The variables analyzed were total distance covered, total distance covered in high-intensity running (≥19.8 km·h−1), and the distance in accelerations (≥2 m·s−2) and decelerations ( ≤-2 m·s−2). Four contextual variables were considered: 1) positional status; 2) match location; 3) match outcome; and 4) match status. Central defenders showed a lower 1-min peak total distance in relation to all other positions (p = 0.001–0.03). Peak physical performance was higher in away matches for high-intensity running, acceleration, and deceleration (p = 0.01–0.03). In matches that ended in losses, peak values for high-intensity running and acceleration were higher compared to draws and wins (p = 0.01–0.04). Regarding the match status, higher values were observed in draws than wins and losses (p = 0.01). Peak running performance vary according to contextual variables of the match in male elite soccer players. Positional differences were found for peak periods, and physical performance was higher in away matches.

“…Thus, athletes with a greater number of games played, greater score of goals scored (or, if goalkeepers, games without goals conceded 15,16 ), and greater use of time players are players with a confirmed competitive profile in past seasons. 17, 18 Analyses focused on these dimensions were those by Garcia-del-Barrio and Pujol 19 and Čeriová et al 20 Additionally, there may be periods of greater demand for certain field positions in the contracting clubs and a greater supply of positions in the ceding clubs (e.g. as a result of the action of the training schools for junior players).…”
Section: An Empirical Analysis Of Transfers Of Players From the First...mentioning
confidence: 99%
“…In all, 1304 international player transfers took place in 2021, a 26.2% increase compared to 2020, which saw a growth of 23.3%. In the women's sector, transfers from Brazil to Portugal also dominate worldwide, with 19 deals, followed by the Mexico-United States (17) and Sweden-United States ( 16) flow.…”
In this pioneering work, we reflect on transfers in women's football. For this purpose, we collected all transfers from the two seasons with the most records in Portugal (the 2019/2020 and 2020/2021 seasons). The four dimensions associated with individual and prestige characteristics conducive to changing clubs, as well as 14 variables, were tested. For treating the problem of the endogeneity of some variables, we used a probit model with instrumental variables. The results obtained showed that high values of “goals per match” increase the probability of a player having an international transfer. Other determinants, such as the position of the transferring club or the player's field position, are also discussed in detail.
“…Every game is unique and, therefore, should be treated independently. In the literature, a lot of work has analyzed the intensity concerning the scoreline [9,11,12,20]. This was done by comparing relevant metrics (e.g., HSR, distance, and sprint distance) depending on the score and also the quality of the opponent.…”
Every soccer game influences each player’s performance differently. Many studies have tried to explain the influence of different parameters on the game; however, none went deeper into the core and examined it minute-by-minute. The goal of this study is to use data derived from GPS wearable devices to present a new framework for performance analysis. A player’s energy expenditure is analyzed using data analytics and K-means clustering of low-, middle-, and high-intensity periods distributed in 1 min segments. Our framework exhibits a higher explanatory power compared to usual game metrics (e.g., high-speed running and sprinting), explaining 45.91% of the coefficient of variation vs. 21.32% for high-, 30.66% vs. 16.82% for middle-, and 24.41% vs. 19.12% for low-intensity periods. The proposed methods enable deeper game analysis, which can help strength and conditioning coaches and managers in gaining better insights into the players’ responses to various game situations.
