Men's doubles professional tennis on hard courts: Game structure and point ending characteristics

2019

Despite the great tradition and importance of the doubles game in professional tennis, no literature has analysed to date the performance of professional players. Therefore, the information on the characteristics of the game, or the tactics related to how the points are won in doubles play is scarce. The objective of this study has been to describe the basic characteristics of the structure of the doubles game, and to establish how the points finish in doubles professional tennis played on hard courts. Thirty-four ATP doubles matches played in 2018 were analysed, which included a total of 40 professional players. As per the game structure, the results showed that, in comparison to the singl…

Cultural Differences in Personality and Aggressive Behavior in Intimate Partner Violence Offenders

2014

Intimate partner violence (IPV) is a ubiquitous and serious problem, the prevalence of which varies greatly around the world. Previous research shows that cultural factors interact with personality and that this interaction influences cognitions, attitudes, and behaviors that are related to personal and individual styles of resolving conflicts. In relation to this, the present study has three aims: comparing the self-reported IPV (physical, psychological and sexual) of English and Spanish offenders, comparing the Millon Clinical Multiaxial Inventory III (MCMI-III) scores of the two groups, and examining the association between country of origin, psychopathology, and IPV. The sample consist…

Detection of behavioural patterns in Olympic male taekwondo athletes

2017

The relationship between athletes’ behaviours is relevant for developing defensive and offensive strategies. Traditionally, sequential analysis has been conducted to assess relationships between two behaviours (one considered as focal and the other as conditioned). The aim of the study was to examine Olympic taekwondo athletes’ behavioural patterns by conducting sequential analyses of tactical actions in bouts. Seventy-five male matches of the London Olympic Games in 2012 were studied to analyse tactical actions: attack (direct and indirect), counterattack (anticipatory, simultaneous and posterior), defensive (cuts, blocks and dodges), and opening actions. A sequential analysis of 2 lags (i…

The relationship between the incidence of winners/errors and the time spent in different areas of the court in elite tennis

2013

Martinez-Gallego R, Guzman JF, James N, Ramon-Llin J, Crespo M, Vuckovic G. The relationship between the incidence of winners/errors and the time spent in different areas of the court in elite tennis. J. Hum. Sport Exerc. Vol. 8, No. Proc3, pp. S601-S607, 2013. Winners and errors have been two of the most studied performance indicators in tennis, contributing to the prediction of match outcome and definition of the playing style of the players. Furthermore, the position occupied by the player on the court has also been shown to be a good indicator of both the final result and style of play. The aim of this study was to examine whether there were differences between game winners and losers i…

Males influence maternal effects that promote sexual selection: a quantitative genetic experiment with dung beetles Onthophagus taurus

2003

J.S.K. was funded by the Academy of Finland, L.W.S. by the Australian Research Council, J.H. by an Australian Postgraduate Award, and J.L.T. by a postdoctoral research fellowship from the University of Western Australia. Recently, doubt has been cast on studies supporting good genes sexual selection by the suggestion that observed genetic benefits for offspring may be confounded by differential maternal allocation. In traditional analyses, observed genetic sire effects on offspring phenotype may result from females allocating more resources to the offspring of attractive males. However, maternal effects such as differential allocation may represent a mechanism promoting genetic sire effects…

Intralocus tactical conflict: Genetic correlations between fighters and sneakers of the dung beetle Onthophagus taurus

2015

Males and females differ in their phenotypic optima for many traits, and as the majority of genes are expressed in both sexes, some alleles can be beneficial to one sex but harmful to the other (intralocus sexual conflict; ISC). ISC theory has recently been extended to intrasexual dimorphisms, where certain alleles may have opposite effects on the fitness of males of different morphs that employ alternative reproductive tactics (intralocus tactical conflict; ITC). Here, we use a half-sib breeding design to investigate the genetic basis for ISC and ITC in the dung beetle Onthophagus taurus. We found positive heritabilities and intersexual genetic correlations for almost all traits investigat…

The impact of digitalization on marketing communications measurement process : case of global B2B industrial companies

2011

The stature of marketing communications function is under a threat within the firms. As the board of management tends to demand the profitability of all business activities, marketing practitioners have for a long time been unable to credibly show the link between marketing communications actions and financial value. Fortunately, the digitalization has offered new insights and opportunities to make the marketing communications actions more measureable. “Everything can be tracked” is an often heard slogan when speaking of monitoring web users’ online behavior facilitated by web analytics software. However, it is questionable how well this slogan fits the marketing communications of Business-…

Technical-Tactical Actions Used to Score in Taekwondo: An Analysis of Two Medalists in Two Olympic Championships

2019

Research in taekwondo has traditionally focused on specific aspects athletes' overall technical and tactical skills, while ignoring other important issues such as identifying how successful athletes score points. The aim of the current study was to follow two medalists through two Olympic Championships (2012 and 2016) to discover the effective patterns associated with scoring in taekwondo using an observational methodology. An ad-hoc taekwondo observational tool was used to codify the actions performed by the athletes. An observational descriptive and multivariate analysis of 1,688 actions performed by the athletes was conducted. A lag sequential and polar coordinate analysis was performed …
