Association between offensive and defensive playing style variables and ranking position in a national football league.

The aim of this study was to determine the association of playing style and efficacy variables with football success in a professional football league. Match statistics were obtained from 23 football teams competing in the 2017-2018 and 2018-2019 seasons of the Spanish national league(LaLiga). Offensive and defensive playing style and efficacy variables were calculated. Pearson's correlation coefficient tests and principal component analysis (PCA) were applied to establish the influence of these variables on the number of points obtained at the end of the season and on the ranking position. In isolation, the efficacy of completion showed the highest association with ranking points and position. A two-dimension PCA explained 77.8% of the variance in the ranking position. In dimension-1 (58.5%), game initiative and attack building, and in dimension-2 (19.3%), efficacy of defensive containment and a lower rate of long passes were within the variables that explained more variance in the ranking position. Success in football, measured by ranking position at the end of the Spanish national league, was associated with several playing style and efficacy variables. Overall, a dominant game style with high efficacy to finish attacking plays, and an offensive game initiative, are most associated with successful football.

Assessing the use of psychological skills by sports category and the relation with sports performance satisfaction.

BACKGROUND: The evaluation of psychological skills by athletes and their relationship with sports performance and satisfaction has been of great interest in recent decades. Likewise, there has been an emergent tendency to focus on developing specific psychological skills for each sport. The principal aim of this study was to determine the frequency with which athletes deploy psychological skills whilst competing and whether their frequency varies in accordance with the technical, tactical and physical characteristics of the sport in question. A further objective was to establish the connection between the frequency of use of psychological skills and athletes' degree of satisfaction with their performance. METHODS: The study comprised 1003 athletes practicing 43 different sports, grouped into 7 categories based on the similarities between them. Frequency of use of the psychological skills was measured with the Test of Performance Strategies 3. RESULTS: The data analyses allowed the following conclusions to be drawn: the degree to which psychological skills are used is dependent on the technical, tactical and physical characteristics of each sport; and the higher the frequency of the use of psychological skills, the greater the athletes' degree of satisfaction with their performance. CONCLUSIONS: These results allow athletes and coaches to increase levels of sports performance by working on the use of psychological skills, adapted to the technical, tactical or physical requirements of the category in which their sport is included. In addition, working on different psychological skills will improve their satisfaction with sports performance.

Relationship between Leadership among Peers and Burnout in Sports Teams.

This study has been conducted with the aim of ascertaining the relationship between peer leaders in sport teams and the levels of burnout experienced by their team-mates. A total of 219 Spanish athletes involved in football and basketball participated in the study. To measure leadership among peers, we employed the Sports Peer Leadership Scale, which comprises 24 items, grouped into 6 primary factors: empathy, influence on decision making, sports values, social support, training orientation and competition orientation. And to measure burnout, we employed the Athlete Burnout Questionnaire, which comprises 15 items which are indicators of physical and emotional exhaustion, devaluation and reduced sense of accomplishment among athletes. The results led to the conclusion that there is a statistically significant negative relationship between perceived leadership capacity and the levels of burnout experience by a team. The greater the level of leadership capacity perceived, the lower the levels of burnout will be. A multiple regression analysis with total burnout as dependent variable and social and task orientations of the leader as predictors showed standardized regression coefficients of -.241 (p = .010) and -.076 (p = .413), respectively for social and task orientation, being the effect size equal to .089.
