Introduction Physical trainers (PTs) are integral for managing load, reducing injury and optimizing performance in professional soccer. However, little is known about how this practitioners operate in the applied setting and how some of the nuances experienced influence practice. Methods This study explored the contemporary practices of PTs in pro...

The increase in the economic value of soccer occurred in parallel with an increase in competing demands. Therefore, clubs and federations evolved to greater specialization (e.g., state-of-the-art facilities and high-profile expertise staff) to support players’ performance and health. Currently, player preparation is far from exclusively club or nat...

The physiological demands of soccer challenge the entire spectrum of the response capacity of the biological systems and fitness requirements of the players. In this review we examined variations and evolutionary trends in body composition, neuromuscular and endurance-related parameters, as well as in game-related physical parameters of professiona...

Methods A professional U19 male football team (n = 26; age = 17.3 ± 1.5 yrs) were divided in a TST (4 sets × 4 reps at 60–85% of one-repetition ma...

This study compared force-time characteristics and muscle activity between the isometric squat (ISQ) and mid-thigh pull (IMTP) in both bilateral (ISQ BI and IMTP BI ) and unilateral (ISQ UNI and IMTP UNI ) stance. Peak force (PF), rate-of-force (RFD) (e.g. 0-300ms) and EMG of the multifidus, erector spinae (ES), gluteus maximus (GM), biceps femoris...

ABSTRACT Purpose: This study investigates the effectiveness of different individualization methods of speed zones during match-play to estimate post-match perceptual recovery in soccer. Methods: Twelve under 19 players undertook field-based assessments to determine their maximal aerobic speed (MAS) and maximal sprint speed (MSS). External load (ex...

Contemporary elite soccer induces high levels of physiological and psychological stress. Therefore, elite clubs should have as a required organizational practice the implementation of a fatigue monitoring system. This chapter discusses the state of research on fatigue monitoring in soccer. The first part of the chapter provides an overview of the m...

Background: Tracking athletes’ external load during a soccer match may be useful to predict post-match acute and residual fatigue. This prediction would allow individual adjustments to training programs to minimize injury risk, improve well-being and restore players’ physical performance and inform the recovery process. Objective: Using a systemati...

This chapter discusses the state of research on concurrent endurance and strength training in soccer. The first part of the chapter provides rationales for soccer as a concurrent modality and describes the physiological and performance adaptations to concurrent training in soccer. Thereafter, some considerations for training programs design will be...

The purpose of this longitudinal study was to investigate whether recruitment status influences neuromuscular and endurance performances in academy soccer players over a 2-year training period (from Under-16 to Under-18). Thirty-seven male soccer players from an elite academy were selected and divided in two cohorts according to their recruitment s...

We examined the influence of competitive standard of the opponent on activity profile and fatigue during preseason friendly soccer matches. Time motion analysis was performed in a male professional soccer team (N = 14) during six friendly games played against professional, semi-professional and amateur-level opponents (PL, SPL and AL). The referenc...

BACKGROUND: In Southern European countries it is very frequent to perform medium-sized games (MSG) as last training drill. We analyzed the individual variability and changes in activity patterns during MSG throughout the preseason. METHODS: Activity profile during MSGs (10v10+goalkeepers, duration: 10-min, field length: 50 m, width: 90 m, area per...

Introduction: Soccer training and completion is conventionally practiced on natural grass (NG) or artificial turf (AT). Recently, AT pitches for training/competition, and of unstable surfaces for injury prevention training has increased. Therefore, soccer players are frequently exposed to variations in pitch surface during either training or compe...

Background Understanding soccer players’ match-related fatigue and recovery profiles likely helps with developing conditioning programs that increase team performance and reduce injuries and illnesses. In order to improve match recovery (the return-to-play process and ergogenic interventions) it is also pivotal to determine if match simulation prot...

Objectives: We analysed the inter-individual relationship between training status and activity pattern in small-sided games (SSG) and full-sized games (FG). Methods: Fourteen Italian elite male senior football players were monitored during four training sessions incorporating SSG, and six FG, during the pre-season. Baseline measurements included, c...

Background: The tournament design of any FIFA World CupTM is characterized with a high amount of games within a short period of time with limited recovery periods.
