Athletic skills acquired through deliberate practice are essential for expert sports performance. Some authors even suggest that practice circumvents the limits of working memory capacity (WMC) in skill acquisition. However, this circumvention hypothesis has been challenged recently by the evidence that WMC plays an important role in expert performance in complex domains such as arts and sports. Here, we have used two dynamic soccer tactical tasks to explore the effect of WMC on tactical performance at different levels of expertise. As expected, professional soccer players exhibited better tactical performance than amateur and recreational players. Furthermore, WMC predicted faster and more accurate tactical decisions in the task under auditory distraction and faster tactical decisions in the task without distraction. Importantly, lack of expertise × WMC interaction suggests that the WMC effect exists at all levels of expertise. Our results speak against the circumvention hypothesis and support a model of independent contributions of WMC and deliberate practice on expert performance in sports.

Numerous studies have shown physical activity (PA) improves psychological functioning and well-being. However, the underpinning processes and mediating variables are less known. There is evidence that beliefs about the benefits of PA contribute to physical health, regardless of actual PA. By applying these findings in the context of mental health, we sought to investigate the role of belief in the benefits of PA in the relationship between self-reported PA and mental health. A total of 381 employed adults completed the Godin Leisure-Time Exercise Questionnaire, Center for Epidemiologic Studies Depression Scale, and Anxiety subscale of the Emotional state scale. Furthermore, participants reported the degree to which they believe that PA has benefits for their psychological health. The mediation analysis shows that greater PA intensity was associated with lower levels of depression and anxiety. Additionally, belief in the benefits of PA on psychological health had a mediating role. Specifically, more intensive PA was related to a stronger belief in PA benefits, subsequently leading to reduced levels of depression and anxiety. We discuss the neurobiological mechanisms underlying the relationship between PA and mental health, alongside the significant role of mindset.

While there is a theoretical and empirical consensus that specific cognitive abilities gained through deliberate sports practice influence sports performance, it is less clear whether basic cognitive abilities that are not specifically related to sports practice are relevant to sports performance. Accordingly, this research examined the roles of basic concentration and visuospatial ability in adolescent soccer performance. Participants were 46 adolescent male soccer players ( M _age = 16.15 years, standard deviation = 1.13) who averaged 7.21 years (standard deviation = 2.2) of prior soccer training. We measured participant’s basic cognitive abilities with the Corsi block and the concentration grid tasks, and we measured their soccer performance through five soccer skills. Concentration had no predictive role in elements of soccer performance, but visuospatial ability was significantly related to tactical abilities, technical skills, mental toughness, and situational awareness and thus, to overall soccer performance. These findings provided support for the importance of visuospatial ability but not concentration (as measured by the concentration grid) in young males’ soccer performance.

On-field aggressive behaviour is often seen on sports fields and numerous theories tried to identify its origins. This study tackled the question of whether the youth athletes in contact and non-contact sports could be differentiated on the basis of the hostile and competitive aggression, and some other characteristics that showed to be related to the aggressive on field behaviour. The study sample comprised 154 of (51% girls) young athletes aged between 10 and 15 years from various contact and non-contact disciplines (wrestling, boxing, taekwondo, football, swimming, athletics, and dance). Participants completed several questionnaires regarding their aggressive behaviour, motivation, anxiety, self-esteem and emotional regulation. Only the competitive, but not hostile, aggression was more present among the youth athletes in contact sports. From all other characteristics, self-esteem, although in a lower extent, predicted affiliation of the non-contact sports group.
