In the context of physical activity and sport, perfectionism and the regular practice of physical activity are related to psychological well-being and the regulation of psychological resources necessary for adaptation to effort and satisfaction. At the same time, the most active students are also those who show greater appetites for physical education classes. The goal of this work was to identify the influence of perfectionist beliefs and the regularity of the practice of physical exercise on psychological well-being. The participants were adolescents (n = 436) aged between 14 and 19 years (M = 16.80, SD = 0.77). They were administered the Multidimensional Perfection Scale, the Psychological Wellbeing Scale, the Global Physical Activity Questionnaire (GPAQv2), and a sociodemographic questionnaire. The results showed, under a non-random and transversal design, that the participants gave important value to physical exercise because they feel both active and vigorous. Regarding perfectionism, the functional aspects of perfectionism (expectations of achievement and organization) correlated positively, while the dysfunctional aspects (fear of committing errors and external expectations) did so negatively with the importance given to physical exercise performed by adolescents; this in turn positively predicted psychological well-being. In this way, the hypothesized model contemplated the relevance of the included variables and reflected the mediation of the degree of importance given to the practice of physical exercise on perfectionist beliefs and psychological well-being. Currently, most physical activity practice proposals for adolescents focus on federated and structured environments for competition, and those that deal with recreational and health-oriented sports are far less common. Hence, “the perfect way of doing sports” for a teenager should be accompanied by cognitive schemes aimed at strengthening psychological resources that allow the regulation of beliefs, attitudes, and behaviors.

Systematic practice of physical activity (PA) in childhood and adolescence enables the development of functional resources for subjective perception of well-being, stimulation of cognitive processes, and construction of the personality. The development of perfectionist beliefs is currently seen as a functional characteristic linked to positive aspects (positive affect, self-esteem, etc.), while its dysfunctional aspects have been associated with anxiety and stress. The aim of this study is to identify which indicators of perfectionism provide functional conditions/skills that, in combination with the level of practice of physical activity, facilitate stress regulation. A sample of 365 adolescents (183 girls and 182 boys) aged between 13 and 17 participated. The results show that as the intensity of physical activity increases, there are significant changes in the indicators for functional perfectionism (high personal standards and organisation), with reference to facilitating (at moderate levels) or limiting (if excessive or absent) perceived stress and, above all, increased intensity of physical activity accentuates dysfunctional perfectionism patterns. This research has made it possible to identify active psychological processes that influence functional or dysfunctional psychological responses in adolescents depending on their level of perfectionism and the intensity of practise of PA.

Perfectionism is a multidimensional personality trait characterized by effort and rigidity in setting high personal standards, accompanied by an excessive tendency toward critical assessments, which plays an important role in cognitive, behavioral, and emotional functioning. During adolescence, personality is built on a fundamental pillar—self-esteem—which plays an important role in sports practice when it comes to achieving the best possible performance. Anger has an emotional component that, interpreted in an unadaptive way, interferes with sports performance. The aim of this study is to assess differences according to self-esteem and perfectionism indicators and anger expression and management in young athletes. The sample included 229 male athletes to the quarries of professional sports with ages between 13 and 17 years. They were administered the Multidimensional Perfectionism Scale, the State-Trait Anger Expression Inventory for Children and Adolescents, the Rosenberg Self-esteem Scale, and a socio-demographic questionnaire. Predictive analysis showed that low personal standards and high levels of organization (indicators of adaptive perfectionism) acted as predictors of state anger, while those showing high personal standards predicted high anger management in athletes with high self-esteem. High personal standards predicted lower indicators of trait anger in athletes with low self-esteem. The results revealed the influence of high self-esteem as a protective factor in the predictive relationship among anger traits and personal standards. The study describes the relationship of these variables in the belongings of young male footballers (under high sport pressure), showing the need to take care of the athletes’ self-esteem in sport environments through prevention programs that include psychological and social resources training systems.

Practice of physical activity is increasingly important for people both as a recreational activity as a health activity. Although it is difficult to find human behaviors that do not have any influence on the health and well-being, it´s possible to show conduct that are among the most important risk factors of major health problems today such as consumption alcohol, obesity and snuff. Regular healthy physical exercise following programmes or frequent and regular autonomous activities improves mental health, autonomy, memory, speed, body image and the feeling of wellbeing, while producing personal stability characterised by optimism, emotional clarity and mental flexibility, leading to a longer life and better health. This model of psychological wellbeing based on the development of human potential and physical exercise, indicates that some aspects of psychological wellbeing are perceived as being more important than others (e.g., self-acceptance, personal growth or life purpose) when studied in relation to autonomy or coping strategies.

Stress as an emotional response with adaptive function can obstruct both academic performance and psychosocial and physiological functioning when it is recurrent, persistent, and intense. Individual characteristics and regular physical activity produce differences in ways of coping with pressure situations, stressing the necessity of teenagers handling them in an effective way for their psychological adjustment and well-being. The purpose of this investigation was to identify how the frequency of physical activity and the influence of certain personality traits (perfectionism and perseverance) moderate stress. The sample was composed of 127 teenage students; tests were administered to measure perfectionism, perseverance, perceived stress, including an ad hoc sociodemographic questionnaire. The results show that particular conditions/skills have a moderating effect on stress perception in students with perfectionist maladaptive tendencies. Training in perseverance allows students to develop resources for handling stress, making it possible to achieve personal standards as well as adapt to one's context.
