A total of 852 adolescents between 12 and 17 years of age were evaluated (M = 14.86, SD = 1.67), randomly selected among a population of secondary school and Baccalaureate students. We applied an “ad hoc” questionnaire on sociodemographic data and the Self-Report of Reasons for the Practice of Physical Exercise (AMPEF) and Self-Report of Barriers to the Practice of Physical Exercise (ABPEF) questionnaires. The results obtained show a prevalence of competition, social recognition, and challenge as motivational factors, and fatigue or laziness as barriers to physical exercise among adolescents. With respect to gender, boys show a greater presence of motivations towards doing physical exercise, while girls show more barriers. In conclusion, the motivational factors and barriers interact and support each other for a better predisposition towards physical exercise.

Purpose: This study aims to determine whether university students are successfully acquiring or improving skills related to teamwork through a variety of extra-curricular activities, such as sports, music, volunteering, international group work experiences and professional practices.Design/methodology/approach: Descriptive statistics have been calculated to evaluate the normal behaviour of the variables. Accidental sampling was used via a cross-curricular study with a quasi-experimental design. An analysis of means was performed using the Student's t-test.Findings: The results show the students to have highly developed interpersonal and communication skills, followed by adaptation and decision-making skills. The lowest scores corresponded to coordination and leadership skills. On the other hand, a significant correlation was established between extra-curricular activities and the acquisition of essential teamwork skills.Originality/value: This study can confirm the important relation between extra-curricular activities and the acquisition of the teamwork skills that play a vital role in the overall development of our students, as well as for their integration into the job market, with particular emphasis on the acquisition of leadership skills which students are most lacking in, but which have shown to improve with any of the proposed activities. The promotion of the extra-curricular activities by the University, could greatly support our students' soft skills acquisition and complement their education.

Social-emotional skills have been an important object of study in recent years due to their relationship with academic, personal and professional success. The aim of this study was to analyse the relationship between these skills and different influential variables. The participants had a mean age of 14.18 years. The instruments used were the Social Emotional Competence Questionnaire (SECQ) and the Physical Activity Questionnaire for Adolescents (PACQ-A). Generally, the results indicated gender differences and no influence of age. Those who engaged in after-school activities scored higher on social awareness. In addition, artistic and musical extracurricular activities were associated with social-emotional skills, whereas sports activities were not. It was also found that the physical activity index was not related to socioemotional factors, except in self-awareness and in a negative way. It is necessary to analyse the quality of the extracurricular programmes offered and the training of the professionals in charge of their development. It also seems important to take into account the gender perspective in competence work, increasing self-management in girls and relationship management in boys.

Socio-emotional skills seem to have an important influence on the academic performance of students. This performance is usually higher in girls than in boys. Our aim was to determine which socio-emotional skills influence academic performance and whether gender is a variable that can explain these differences. The results indicated that the socio-emotional skills of adolescents were high, highlighting self-awareness, relationship management, and decision-making. The lowest scores were in social awareness and self-management. Girls obtained higher grades, and students with higher grades had a higher level of social-emotional skills, except in self-management, where there were no differences. Self-management was greater in boys and relationship management was greater in girls. Students who failed did not differ from those who obtained very high results, except in decision-making. Overall, decision-making appeared to be the most important variable in students’ academic performance. Therefore, it would be necessary to design strategies that promote this ability in students. Hence, the adoption of active and collaborative methodologies that facilitate the achievement of this goal is suggested.

Purpose: Physical fitness has shown to be positively related with young people's general mental health, mainly due to the changes in body composition derived from a regular sportive practice. Thus, the aim of this study was three-fold: 1) to analyze the relationship between physical fitness with the mental health status assessed as physical self-concept and self-esteem, 2) to study whether self-esteem offers longitudinal relationships with physical fitness three months after the first assessment, and 3) to know the most implicated variables of physical fitness in mental health variables. Method: A total of 1441 adolescents aged 12 to 19 years (mean=14.52; standard deviation=1.96 years), being the 49.5 % of them girls, from 4 high schools in Andalusia, Spain, participated in the study. The EUROFIT battery test was administered to the participants, as well as some questionaries to assess the physical self-concept and the self-steem. Physical tests and self-concept were assessed in an only temporal point, while self-esteem was analyzed longitudinally. Results: The results obtained indicated that physical self-concept was related to physical fitness, while self-esteem was especially related to the Course Navette test. Conclusions: These results suggest that having great levels of physical fitness, especially related to aerobic endurance, may help to have higher levels of physical self-concept and self-esteem as components of mental health in Spanish adolescents.

Background: Anxiety is one of the most complex and the most studied constructs in psychology, and it is extremely frequent in high-level sportsmen and women. The main goal was to study the influence of sex, age, type of sport, sport modality, other professional occupation, and competitive level on the competitive anxiety symptoms and self-confidence of elite athletes. Methods: A descriptive cross-sectional study was carried out with Colombian elite athletes who were members of the “Support to the Excellence Coldeportes Athlete” program. The total population studied included 334 Colombian elite athletes: mean age 27.10 ± 6.57 years old with 13.66 ± 6.37 years practicing his/her sports modality. The precompetitive anxiety symptoms of the participants were assessed using the Competitive State Anxiety Inventory—2R (CSAI-2R). Results: Men showed higher levels of self-confidence than women. Younger athletes had a higher cognitive and somatic anxiety. The athletes of individual sports had a higher mean somatic anxiety than those of collective sports. The higher-level athletes had lower values of cognitive and somatic anxiety and higher levels of self-confidence. Finally, the values of anxiety symptoms positively correlated with each other, and negatively correlated with self-confidence. Conclusion: Individualised psychological intervention programs adapted to elite athletes are needed, considering the divergent results found in various variables of scientific interest.
