Non-starters soccer players have a great role within the team, being indispensable to reduce fatigue, as

well as to maintain and increase the team’s performance during the match. This study analyzed the physical performance of the starters (STA) and non-starters players (NOP) during competitive soccer matches.

The aim of this study was to investigate the external load (EL) indicators differences in players of different playing positions (central backs CB, external strikers ES, fullbacks FB, midfielders MF, strikers ST, wide midfielder WM) between and within different sport-specific tasks and official matches.

This study aimed to evaluate the impact on physical demands induced by FIFA’s new rule implemented based on the number of substitutions caused by COVID-19.

The aims of this study were to (i) analyze the physical and physiological responses of four matches competition and (ii) to investigate the relationships among three different pitch dimensions of small-sided game (SSG) on the youth soccer players.

This study aimed to explore the relevance of the relative age effect (RAE), maturity status and anthropometry, and their influence on coaches’ assessment of players’ performance, analyzing both genders and different types of academies (elite vs. non-elite only male displayed).

The purpose of this study was to evaluate the relationships between objective fatigue variables (Squat Jump (SJ) and Countermovement Jump (CMJ)) measured on day-2 to the game and subjective fatigue (Rating Perceived Exertion (RPE) measured on day-3 to the game and Hooper Index (HI) measured on day-2).

The aim was to compare the biceps femoris long head (BFlh) architecture between football players with (twelve) and without (twenty) history of BFlh injury before and after a repeated sprint task. 

Game time is a crucial factor for player development. Players and agents might be interested in clubs and philosophies that enables game time, consequently, having a look on the percentage of minutes played by footballers who had not yet turned 20 in domestic league matches played over the last five years. A total of 1,168 clubs in 76 leagues worldwide were analysed.

This prospective study aimed to examine in detail the effects of sports injuries on professional football players’ weekly external load performances.

The primary aims of this study were to examine the application of maturity status bio-banding within professional soccer academy programmes and understand the methods employed, the intended objectives, and the potential barriers to bio-banding.

The present study examined the effects of stressful constraints during soccer trainings on psychological skill development and internal load when compared with control (non-stressful) trainings.

This study examined the effects of a six-week preparatory training program on physical performance and physiological adaptations in junior soccer players. Additionally, we investigated whether a relationship existed between external and internal loads.

The temporary transfer of players is practiced regularly in professional football. It is used to allow the development of young players who do not yet have sufficient playing experience or a good enough sporting level to play in their owner club.

The aim of this study was to compare the effects of small-sided soccer games (SSSGs) and traditional warm-up (TWU) routines on physical fitness qualities in soccer players.

The present study aimed to contextualise physical metrics with tactical actions according to general and specialised tactical roles.

Temporal changes in the total running demands of professional football competition have been well documented, with absolute running demands decreasing in the second half. However, it is unclear whether the peak match running demands demonstrate a similar decline.

The aim was to compare the effects of playing one or two games per week on subjective perceived exertion (RPE) and (RPE-based) training load, monotony index, sleep, stress, fatigue, and muscle soreness (Hooper index), total mood disturbance, and injury rate in elite soccer players.

This study aimed to investigate the effects of contextual match factors (quality of opposition, match outcome, change of head coach or playing style) on internal and external load in elite Brazilian professional soccer players, considering the total and effective playing time.
