Listening to adolescents’ voices has been important to promote meaningful physical activity (PA) opportunities. Therefore, an updated systematic review of the available qualitative literature on adolescents’ perspectives on the barriers and facilitators of PA was conducted, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies published between 2014 (date of the last systematic review) and 2020 were searched in the Web of Science, EBSCO, and SCOPUS databases. Based on the inclusion criteria applied, 30 out of 8069 studies were included in the review. A thematic analysis was used to inductively and deductively analyze the perspectives of ~1250 adolescents (13–18 years). The studies took place in 13 countries from different continents. The main PA barriers and facilitators of PA were presented and discussed around five higher-order themes: (1) Individual factors (e.g., psychological—motivation, self—efficacy; cognitive—knowledge, understanding; physical—motor skills); (2) social and relational factors (family, friends, significant others); (3) PA nature factors (fun, school-based PA and physical education); (4) life factors (time and competing activities; life-course); and (5) sociocultural and environmental factors (e.g., availability/access to PA facilities, programs; urban/rural zones). By transnationally framing adolescents’ voices, this study provides updated evidence and discusses innovative implications for developing tailored interventions and pedagogical strategies aimed at promoting active and healthy lifestyles.

This study examines physical education pre-service teachers’ (PTs) self-efficacy and practicum experiences as self-efficacy sources through a mixed-method approach. For the quantitative phase, a self-efficacy questionnaire was applied to 141 PTs. Results showed a stronger self-efficacy in the relationship with students and discipline promotion. Lower self-efficacy was linked to instructional strategies. Concerning the qualitative phase, eight PTs were interviewed. PTs with higher self-efficacy reported professional experiences before practicum as mastery experiences. During the practicum they highlighted as mastery experiences: classes’ characteristics, planning and teaching practice; lesson observation as vicarious experiences; and post-lesson conversations as verbal persuasion. PTs with lower self-efficacy reported classes’ characteristics and teaching practice as failure experiences. Lesson observation was linked to negative vicarious experiences and post-lesson conversations were associated to negative emotions and the absence of verbal persuasion. This study’s results have implications inasmuch as they confirm the role of the practicum in teacher education programmes and the importance of training supervisors in the implementation and management of the training experience, thus contributing to PTs’ self-efficacy development.

Based on a socio-ecological framework for physical education (PE), this study explored and analysed the perspectives of physically active and inactive adolescent boys and girls with different socioeconomic status (SES), regarding the meanings that PE had on their physical activity (PA) lifestyles throughout childhood and adolescence. An interpretative and qualitative design was adopted and operationalised through an individual two-hours in-depth interview. Thematic analysis identified five main themes that distinguish active from inactive adolescents: ‘Early experiences of PE at primary school’; ‘PE experiences in middle and secondary school’; ‘Friendly, professional and pedagogue. That’s what I want from my PE teacher’; ‘Friends in PE and PA’; ‘Active lifestyles? Are schools and PE ready for making a difference …’. Regardless of the lifestyle, girls revealed more PE negative experiences, related to uninteresting and competitive activities, groups’ constitution and logistic factors. SES played a major role on their PA and PE experiences, with low SES adolescents having limited opportunities inclusively within the primary school PE context. This study provides evidence for the importance of promoting positive PE and PA experiences in early years. Based on adolescents’ voices, several recommendations are discussed that can be considered for improving PE professionals’ effectiveness in promoting active lifestyles.

Children’s motor competence is known to have a determinant role in learning and engaging later in complex motor skills and, thus, in physical activity. The development of adequate motor competence is a central aim of physical education, and assuring that pupils are learning and developing motor competence depends on accurate assessment protocols. The MOBAK 1 test battery is a recent instrument developed to assess motor competence in primary physical education. This study used the MOBAK 1 to explore motor competence levels and gender differences among 249 ( M _age = 6.3, SD = 0.5 years; 127 girls and 122 boys) Grade 1 primary school Portuguese children. On independent sample t tests, boys presented higher object movement motor competence than girls (boys: M = 5.8, SD = 1.7; girls: M = 4.0, SD = 1.7; p < .001), while girls were more proficient among self-movement skills (girls: M = 5.1, SD = 1.8; boys: M = 4.3, SD = 1.7; p < .01). On “total motor competence,” boys ( M = 10.3, SD = 2.6) averaged one point ahead of girls ( M = 9.1, SD = 2.9). The percentage of girls in the first quartile of object movement was 18.9%, while, for “self movement,” the percentage of boys in the first quartile was almost double that of girls (30.3% and 17.3%, respectively). The confirmatory model to test for construct validity confirmed the assumed theoretical two-factor structure of MOBAK 1 test items in this Portuguese sample. These results support the MOBAK 1 instrument for assessing motor competence and highlighted gender differences, of relevance to intervention efforts.

Given the need for comparative research on the participation of adolescents in physical education (PE) classes as a privileged space for physical activity (PA) promotion, this study sought to estimate, analyse and compare the prevalence of participation in PE classes among adolescents from 54 countries and to examine sex, age, country income and world regions disparities. Data from the Global Students Health Survey (2010–2015) were used, comprising 170,347 adolescents (90,305 girls, aged 13–17 years) from nationally representative samples of 54 countries—of which 7 are low-income, 23 lower-middle-income, 14 upper-middle-income and 10 high-income—and six world regions. The weighted percentages of adolescents participating in PE classes (never, 1–2 days/week, 3–4 days/week, 5 or more days/week) were estimated along 95% confidence intervals and compared across sex, age, country income, region, and country. Most adolescents reported to participate in PE on 1–2 days/week (55.2%), but almost 20% of adolescents reported never participating in PE. Girls, compared to boys, presented a lower prevalence for participating ≥5 days/week (girls 16.8%, boys 20.0%). The prevalence of participating in PE on ≥3 days/week was higher among adolescents aged 13–14 years when compared to adolescents aged 15–17 years (boys: 30.9% vs. 24.6%; girls: 26.1% vs. 18.2%). Concerning the countries’ income, the prevalence of never participating in PE was higher in high-income countries, and participating on ≥3 days/week was higher in low-income countries, but further research is recommended. The findings suggest that national, regional and worldwide data highlight the importance of improving participation in PE, particularly for girls and older adolescents. An improved and continued monitoring of PE policies and their actual implementation is needed worldwide.
