This study on the 2018 Russia FIFA World Cup examined: i) potential variations of ball possession, match running performance, player prominence, team network properties according to outcome and playing formation; ii) relationships between prominence total distance covered possession. Sixty-one matches were analysed (n = 988 observations). Running performance was examined using in (TDIP) out that travelled different speed-range categories. Player (micro) (macro) obtained social analysis where...

Abstract Background This study aimed to compare the match running performance between bottom- and top-ranked teams in professional soccer players over 2020 season of Brazilian National 2nd Division League. In addition, this verified independent interactive effects playing position contextual factors on outputs these teams. Methods Forty-eight male outfield participated (top-ranked team, n = 24; bottom-ranked 24). The distance- accelerometry-based measures were recorded during 69 matches...

Purpose This study aimed to investigate the effects of match location, quality opposition, outcome, and playing position on internal load (IL), external (EL), interpersonal interactions in professional soccer players. Also, relationships between parameters were measured. Methods Fourteen matches from 16 Brazilian players analysed. IL was obtained through rating perceived exertion. EL quantified with Global Positioning System (e.g., high-intensity running [HIR]). Interpersonal measured by...

This study aimed to quantify the weekly training load distributions according match location, opponent standard, and outcome in professional soccer players. Rate-of-perceived-exertion-based (sRPE) distance- accelerometry-based measures were monitored daily during 52 sessions 11 matches performed by 23 Athletes who played ≥ 60 min non-congested weeks considered for data analysis. The days close away (e.g., one day before = MD-1) presented greater sRPE, distance-based volume measures,...

This study aimed to verify the effects of congested fixture and matches' participation on internal external workload indexes in professional Brazilian soccer players. Rate perceived exertion-based training load (sRPE), distance- accelerometry-based measures were daily monitored over 119 sessions 33 matches performed by 29 male outfield Weeks classified as (n = 11, two or more within a 7-day period) regular 10, one match less period). The players divided based participation: (1) who played ≥...

This study investigated the effects of match location, quality opposition (classified into: strong [1st to 4th position]; intermediate [5th 15th weak [16th 20th position]), and outcome on running performance starters non-starters from a top elite Brazilian soccer team. Absolute measures were calculated using total distance, high-speed (19.8–25.2 km·h −1 ), sprinting (≥ 25.2 distance high-acceleration (> 2m·s 2 deceleration (< −2m·s ) recorded by GPS units sample young players ( N = 25)...

Despite their immunosuppressive effects, corticosteroids have long been used as adjunct therapy (aCST) in the treatment of infectious diseases. The rationale is that certain infections it necessary to decrease exacerbated host's inflammatory response, which can otherwise result tissue damage and organ dysfunction. In fact, a major concern treating paracoccidioidomycosis (PCM) intense response Paracoccidioides brasiliensis, be further intensified by antifungal therapy. Depending on its...

The purpose of this study was to investigate the association between offensive tactical knowledge and soccer-specific motor skills performance. Fifteen participants were submitted two evaluation tests, one assess their technical analysis. performance measured through four tests soccer skills: ball control, shooting, passing dribbling. based on a assessment system called FUT-SAT (Analyses Procedural Tactical Knowledge in Soccer). Afterwards, scores ranked with without use cluster method. A...

The aims of this study were: (i) to compare the external and internal load during a 6-a-side small-sided game (6v6-SSG) according age-group; (ii) relate these parameters between 6v6-SSG official matches; (iii) test reliability 6v6-SSG. A total 51 Brazilian youth soccer players participated in (U11 [n = 16]; U13 10]; U15 9]; U17 8]; U20 8]). Three experiments were conducted. Experiment A: fifty-one U11 submitted 6v6-SSGs (n 10 games; two for each age-group). B: thirty-two randomized also play...

The aim of this study was to evaluate the correlation between tools commonly used in detection physiological changes, such as clinical complaints, a biochemical marker muscle injury, and performance data during official matches, with infrared thermography, which has been possible tracking musculoskeletal injuries athletes. Twenty-two athletes from professional soccer club (age 27.7 ± 3.93 years; BMI 24.35 1.80 kg/cm 2 ) were followed season national championship, totaling 19 matches an...

The main aim of this study was to analyze the relationship between field tests and match running performance using computational tracking technology in high-level young Brazilian soccer players.Twenty-five male players participated (U-15, N.=13; U-17, N.=12). In same week, were submitted actual matches. were: Maximum Speed (10-30 m), Zig-Zag, Running-based Anaerobic Sprint Test, Yo-Yo Intermittent Recovery Test Level 1. Additionally, participants performed match-play. Match collected a fixed...

Rothia aeria is an uncommon pathogen mainly associated with endocarditis in case reports. In previous reports, by R. was complicated central nervous system embolization. the we report herein, diagnosed after acute self-limited diarrhea. addition to common translocation of from oral cavity, hypothesize possibility intestinal translocation. Matrix-assisted laser desorption ionization-time flight mass spectrometry and genetic sequencing are important tools that can contribute early more...

The aim of this study was to describe weekly acute workload (wAW), chronic (wCW), acute: ratio (wACWR), training monotony (wTM), and strain (wTS) variations over a full season across playing positions. Twenty-one professional soccer players were daily monitored during 48 consecutive weeks. Total distance, sprint total distance (STD), high-speed running (HSRd), maximum speed, number the repeated sprints, body load (BL) obtained matches using Wearable Inertial Measurement Unit. wAW determined...
