The purpose of this study was to compare the blood lactate (La-), heart rate (HR) and percentage of maximum HR (%HRmax) responses among the small-sided games (SSGs) in elite young soccer players. Sixteen players (average age 15.7 6 0.4 years; height 176.8 6 4.6 cm; body mass 65.5 6 5.6 kg; VO2max 53.1 6 5.9 ml · kg(-1) · min(-1); HRmax 195.9 6 7.4 b · min(-1)) volunteered to perform the YoYo in...

In the recent years, there has been remarkable development in the scope and quality of soccer physiology and medicine. However, there is a shortage of descriptive data concerning the physical and physiological characteristics of soccer players from Eastern Europe while much more literature exists providing information on male Western European and American soccer (Rhodes et al., 1986; Davies et ...

There is no dispute that acute hamstring injury is a major sports injury, 1–6 particularly in football codes 2 3 5 6 and other sports that demand high-speed running. 1 The purpose of this editorial is to provide the reader with evidence-based tips for optimising hamstring injury prevention. Early return to sport (≤3 weeks) is often proposed for hamstring injuries, 7 even though basic research c...

Abstract Soccer is constantly changing regarding the demands of new generation. At its best, young players develop outstanding technical and tactical skills as well a wealth competition experience. In addition to targeted training, maintaining motivation one biggest challenges facing youth coaches. One possible way build their confidence while having fun. As game form, 3 vs. unites main events ...

In this paper, we study collective interaction dynamics emerging in the game of football-soccer. To do so, surveyed a database containing body-sensors traces measured during three professional football matches, where observed statistical patterns that used to propose stochastic model for players' motion field. The model, which is based on linear interactions, captures good approximation spatiot...

This study aimed to examine the utility of inertial measurement unit (IMU) technology identify angle, step-specific, and side-specific differences between youth soccer players with without a history lower limb injury during soccer-specific field tests. Thirty-two youths (mean age 16.4 years) who were elite (Females n = 13, Males 19) wore IMUs pre- postseason change-of-direction assessments. A r...

This study examines gender differences in risk-taking behavior among managers a female-dominated industry. Using data from international top-level women's soccer, we provide evidence that male coaches show lower level of than female on average. We also find U-shaped age effect is independent gender, meaning young and more mature individuals tend to take riskier decisions. Our main results there...

Abstract Bullying is a social problem that has been studied most in schools but affects other contexts. However, there general lack of studies on bullying sports. The aim this study was to determine the prevalence among youth soccer players. Participants were 1,980 players (88.2% boys) aged 8 13 years (M age = 10.5, SD 1.68) from 25 clubs Catalonia, Spain. An ad hoc questionnaire administered a...

We present a fully convolutional neural network architecture that is capable of estimating full probability surfaces potential passes in soccer, derived from high-frequency spatiotemporal data. The receives layers low-level inputs and learns feature hierarchy produces predictions at different sampling levels, capturing both coarse fine spatial details. By merging these predictions, we can produ...
