As previous literature updates, I have performed a PubCrawler search looking for football articles in NCBI Medline (PubMed) and GenBank databases. 

Following studies were retrieved for this week:

This study aimed to report possible anthropometrical and physical performance differences between youth soccer players with different maturity status and to report the coaches’ expectations, hypothesizing that coaches would expect more from players with advanced maturity.

This study analyzed the influence of the coaches’ encouragement on the mental and physical load in soccer practices.

The aims of this study were to analyze the association between linear sprint, curved sprints (CS) and change-of-direction (COD) speed performances and compare the association and direction of asymmetries between skills.

This study aimed to examine the acute physiological effect of shuttle-run-based high-intensity intermittent exercise (HIIE) performed at the same relative speed (i.e. 100%PST−CAR) on sand (SAND) and grass (GRASS) in male junior soccer players.

Following studies were retrieved for this week:

We aimed to analyze the magnitude and direction of inter-limb asymmetries in ankle dorsiflexion range of motion (ROM), power (using iso-inertial devices) and a neuromuscular skill (change of direction). Secondarily, we aimed to determine the relationship between inter-limb asymmetry scores for each test and also between these scores and the scores for the different performance tests.

The aim of this study was to examine the duration and information (number of teammates and opponents) of the players’ scanning behavior of four elite football midfield players in an 11 vs. 11 using mobile eye-tracking technology.

Following studies were retrieved for this week:

The study aimed to identify the effects of situational (match location, match outcome and strength of team/opponent team) and environmental (ambient temperature, relative humidity, WBGT, ground and weather condition) factors on the physical and technical activity of elite football on individual playing positions.

The purpose was to identify risk factors for inversion ankle sprains among male collegiate soccer players.

This study sought to evaluate the training load in different age category soccer players associated with distinct pitch size small-sided games (SSGs).

The current study was conducted to compare muscle damage biomarkers in single- vs. multi-match weeks in elite soccer players for two consecutive seasons. A secondary objective was to analyze the influence of playing position and exposure time on muscle damage in single- vs. multimatch weeks.

Clear decreases in horizontal force production capacity during sprint acceleration have been reported after hamstring injuries (HI) in football players. We aimed to analyze the association between sprint running horizontal force production capacities at low (FH0) and high (V0) velocities and HI occurrence in football.

The purpose of the study was to examine the relationship between elite youth athletes’ perceptions of coaches’ transformational coaching-behaviours and variables linked to transformational leadership in other settings (i.e., group cohesion, motivational climate, self-regulation of learning and athlete satisfaction.

In football, annual age-group categorization leads to relative age effects (RAEs) in talent development. Given such trends, relative age may also associate with market values. This study analyzed the relationship between RAEs and market values of youth players.

The aim of this study was to examine the effects of chronological age on acceleration and deceleration match performance in professional footballers.

As previous literature updates, I have performed a PubCrawler search looking for football articles in NCBI Medline (PubMed) and GenBank databases. 

Following studies were retrieved for this week:

The purpose of the study was to evaluate predicted maturity offset (time before age at PHV) and age at PHV (chronological age [CA] minus maturity offset) in a longitudinal sample of 58 under-13 club level soccer players in central Portugal for whom ages at PHV were estimated with the SITAR model.

This study aimed to investigate match running performance in U14 male soccer players in Norway, and the influence of position, competitive level and contextual factors on running performance.
