The Influence of Pitch Dimensions during Small-Sided Games to Reach Match Physical and Physiological Demands on the Youth Soccer Players.

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. Fifteen male U19 soccer players (age 17.3 ± 0.

Characterisation of Goal Scoring Patterns during Open Play Related to Zone Pitch Division and Number of Players Involved in the 2018 FIFA World Cup.

The aim of this study was to characterise all the goal scoring patterns during open play (elaborate attacks versus counterattacks) related to zone pitch division and the number of players involved in the 2018 FIFA World Cup in Russia. An Iterative Dichotomiser 3 (ID3) decision tree algorithm was used to classify all the goal scoring patterns (94 goals in 64 matches). The results did not show statistical differences between the type of scoring goal during the 2018 FIFA World Cup ( > 0.

Influence of artificial turf temperature on physical performance and muscle contractile properties in football players after a repeated-sprint ability test.

This study aimed to analyse the effect of playing surface temperature on muscular and thermal response to a repeated-sprint ability (RSA) test in football players. Thirty-two male football players (23 ± 5 years; 1.77 ± 0.

Comparison of the Physical Demands of Friendly Matches and Different Types On-Field Integrated Training Sessions in Professional Soccer Players.

The aim of this study was to investigate the relationships among physical demands of two friendly matches (FMs) and three task training sessions (TS) combining in a different way: a Small-Sided Game (SSG), Mini-Goals (MG), a ball Circuit Training (CT) and a Large-Sided Game (LSG): SSG+MG+LSG (TS), SSG+CT+LSG (TS) and MG+CT+LSG (TS). The TS and match demands in running intensities were monitored in fourteen professional soccer players (age = 23.2 ± 2.

Physical Performance Differences Between Starter and Non-Starter Players During Professional Soccer Friendly Matches.

The aim of this study was to investigate the physical performance differences between players that started (i.e. starters, ≥65 minutes played) and those that were substituted into (i.

Relationships Among Circuit Training, Small-Sided and Mini Goal Games, and Competition in Professional Soccer Players: A Comparison of On-Field Integrated Training Routines.

Giménez, JV and Gomez, MA. Relationships among circuit training, small-sided and mini goal games, and competition in professional soccer players: A comparison of on-field integrated training routines. J Strength Cond Res 33(7): 1887-1896, 2019-The aim of this study was to investigate and compare different physical variables and load indicators of 2 small-sided game (SSG) formats and ball circuit training (CT).

Physical responses of professional soccer players during 4 vs. 4 small-sided games with mini-goals according to rule changes.

The aim of this study was to investigate the influence of the number of ball touches authorised per game (one touch [T1], two touches [T2], and free touches [FT]) on the players' physical responses throughout the bouts in 4 vs 4 soccer small-sided games (SSGs) with mini-goals (without a goalkeeper). Fourteen professional Polish players (age 23.2±2.

Comparison of the movement patterns between small- and large-sided game training and competition in professional soccer players.

Background: The purpose of this investigation was to compare the movement patterns of professional soccer players during a small-sided game (SSG), a large-sided game (LSG), and a competitive friendly match (FM).

Methods: Fourteen professional players participated in three training routines with a similar relative pitch area per player. The SSG and LSG consisted of 8 repetitions of 4-min game play, interspersed by 2 minutes of active recovery, and their data were compared to the first 32 minutes of a FM.

Increase of R-/S-methadone enantiomer concentration ratio in serum of patients treated with either nevirapine or efavirenz.

An increased methadone enantiomer ratio (R/S) was associated to both nevirapine (179%, n=5) and efavirenz (36%, n=9) treatments when compared with that of controls (n=52). Additionally, in four follow-up patients, both R- and S-methadone normalized concentrations decreased (19%-93%) while R/S increased (22%-314%) following nevirapine/efavirenz treatment. R/S decreased (42%) after non-compliance with efavirenz treatment.

Detection of clinical interactions between methadone and anti-retroviral compounds using an enantioselective capillary electrophoresis for methadone analysis.

A capillary electrophoresis method was developed to detect interactions between methadone and anti-retroviral compounds. Eight subjects, who underwent methadone maintenance treatment in the Province of Alicante (Spain), consented to participate in the present study. Of those, one subject was followed up for 123 days to detect drug-drug interactions.
