Influence of competition on performance factors in under-19 soccer players at national league level.

2020

The aim of this study was to analyse and quantify the acute effects of competition on several performance factors in under-19 male soccer players. To this end, 198 national league players (17.56 ± 0.78 years) performed various tests to measure jump capacity, kicking velocity and sprint times immediately pre-match (T1), at half-time (T2) and post-match (T3). Tests included kicking the ball to measure ball velocity (KICK), sprinting for 40 meters, timing the first 30 meters (30mACCEL), the last 10 meters (10mACCEL) and the total distance (40mACCEL), and performing countermovement jumps (CMJ). For subsequent analysis, the sample was divided into 5 playing positions: goalkeepers (n = 24), defen…

The oral-facial-digital syndrome gene C2CD3 encodes a positive regulator of centriole elongation

2014

Centrioles are microtubule-based, barrel-shaped structures that initiate the assembly of centrosomes and cilia(1,2). How centriole length is precisely set remains elusive. The microcephaly protein CPAP (also known as MCPH6) promotes procentriole growth(3-5), whereas the oral-facial-digital (OFD) syndrome protein OFD1 represses centriole elongation(6,7). Here we uncover a new subtype of OFD with severe microcephaly and cerebral malformations and identify distinct mutations in two affected families in the evolutionarily conserved C2CD3 gene. Concordant with the clinical overlap, C2CD3 colocalizes with OFD1 at the distal end of centrioles, and C2CD3 physically associates with OFD1. However, wh…

Playing tactics, contextual variables and offensive effectiveness in English Premier League soccer matches. A multilevel analysis.

2020

The aim of this study was to investigate the combined effects of tactical and contextual indicators on achieving offensive penetration and scoring opportunities in English Premier League (EPL) soccer matches. A total of 1971 team possessions from 20 random matches were evaluated by means of multidimensional observation. The EPL matches had a great proportion of fast attacks (36.0%) followed by combinative (29.6%), direct attacks (24.1%) and counterattacks (9.5%). Multilevel logistic regression models revealed that counterattacks (OR = 3.428; 95% CI: 2.004–5.864; P<0.001) were more effective to create goal scoring opportunities than combinative attacks, while direct attacks showed to be less…

MOTIVATION OF LATVIAN YOUNG ATHLETES TO BUILD A DUAL CAREER

2020

The study explores factors that motivate high- performance athletes to manage their dual career while studying in secondary school. The dual career experience of Latvian youth is obtained. The paper analyses the results from young high- performance athletes’ questionnaire, focusing on the support young athletes receive and would need to receive in their education and sports training process. A survey, based on an individual approach, was carried out in training camps and schools; 125 high- performance athletes of the secondary school age completed the questionnaire (19 questionnaires were filled in electronically). The gained data were processed with the statistics methods using SPSS Statis…

The Ethical and Political Contours of Institutional Promotion in eSports: From Precariat Models to Sustainable Practices

2020

This study evaluated five early cases in which esport developer Riot Games made rulings regarding activities and infractions by members of various institutions related to its product, League of Legends. The findings of this study support future theoretical exploration of other esports in seeking a fuller understanding of issues related to consent, power differentials, and roles and behaviors expected of the institutional activities of players and teams in competition. Increased investigation of these—and other—issues from an ethical standpoint could lead to a framework that not only would facilitate future study but also bring opportunities for improvements in practices in concert with nece…

Does the crowd matter in refereeing decisions? Evidence from Spanish soccer

2016

This paper analyses referee home bias with data from the First Division of the Spanish Football League between the 2002/03 and 2009/10 seasons. The aim is to assess the behaviour of the referee in relation to two decisions, namely free kicks awarded and players booked. The main contribution of this paper is the way in which it analyses referee bias; free kicks and bookings are not considered independent elements, instead it is presumed that the number of free kicks awarded has an impact on the cards shown. Regarding methodology, two random effects panel-data regression models are estimated. The results obtained do not confirm, at least in the period under analysis, that Spanish soccer refer…

From fringe to fringe: the shift from the clericalist League of Polish Families to the anticlericalist Palikot Movement 2001–2015

2017

The period between 2001 and 2015 brought two events in Poland that deserve to be called phenomena. In 2001 the rightist, clericalist League of Polish Families entered the Sejm. Ten years later, the leftist, anticlericalist Palikot Movement achieved spectacular success in the 2011 elections. These events give a picture of a radical shift in the Polish political scene: a rightist clericalist party disappeared from the right flank of the political scene, while a new, leftist-anticlericalist formation appeared. The article makes reference to a set of five explanations on both the causes and consequences (and permanence) of the observed changes. I argue that only a concurrence of a number of com…
