Tyrosine has been proposed to potentially provide ergogenic benefits cognitive and physical performance in physiologically demanding environments. However research into its effectiveness on during exercise the heat revealed mixed findings. This study examined effects of a commonly employed dosage tyrosine supplementation soccer players' decision-making performance, appraisal, affective states, prolonged high-intensity intermittent hot conditions. Eight trained male players completed 92-minute cycling sprint protocol whilst responding soccer-specific tasks at various time points 32°C (50%rh), two counterbalanced conditions; (150mg.kg-1) placebo. No differences were found for peak power output (p = .486; 715 ± 98W vs 724 98W, respectively), .627; 86.9 10.7% 88.6 7.0%, appraisal .693, 0.90 0.42 0.88 0.39, respectively) nor states .918; 1.15 1.55 1.14 1.70, between placebo Also, no condition by interaction noted these outcomes. In sum, was ineffective facilitating (self-paced) activity, decision-making, alleviating perceptual strain, exercising heat. However, future may wish consider alternative approaches (e.g., timing, dosage) or induce heightened physiological strain extend

Neuropsychophysiological Aspects of Soccer Performance: A Bibliometric Analysis and Narrative Review

Perceptual and Motor Skills, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 16, 2024

In recent years, there has been growing scientific interest in the neuropsychophysiological aspects of soccer performance. The purpose this study was to conduct a bibliometric analysis identify and review key topics within dimensions performance any research voids that warrant further attention. We retrieved 192 documents from Scopus database anayzed extracted data using VOSviewer software analysis. applied both techniques (including number per year, top 20 authors by citations, 15 sources documents) science mapping (co-authorship, bibliographic coupling, co-citation, co-occurrence). co-occurrence identified three main clusters themes. first cluster focused on relationship between physical cognitive factors, second technical-tactical performance, third health well-being. Our findings emphasize significant role factors all highlight importance integrating training enhance player underscore need for deepen our understanding these relationships.

Evolution of passing network in the Soccer World Cups 2010–2022

Science and Medicine in Football, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 12

Published: Aug. 6, 2024

This study investigates the evolution of passing networks (PN) at both team and player levels in FIFA World Cups (WC) from 2010 to 2022. Analyzing 256 matches (7328 observations) using a multiple-camera tracking system across four WCs, we considered six playing positions: goalkeeper (n = 521), central defender 1192), fullback 1223), midfielder 2039), winger 1320), forward 1033). We used 17 network metrics contextual variables such as formation, ranking. Linear mixed-effect models analyzed differences PN parameters by year strength.
