Physical inactivity commonly occurs throughout one’s life, particularly during adolescence and young adulthood. Multiple factors can negatively influence participation in physical activity, but there has been no review examining the barriers to physical activity among high school and university students. Therefore, the aim of this systematic review was to summarize evidence of barriers to the practice of physical activity among high school and university students. The literature search was conducted without time limits using five databases, including CINAHL, Cochrane Library, Embase, PubMed, and Scopus. In total, 59 studies (37 with high school students [n = 22,908] and 22 with university students [n = 15,411]) were included. The main barriers identified in high school and university students were lack of time, lack of motivation, and lack of accessible places. These findings may be useful in designing and implementing evidence-informed interventions and programs for physical activity promotion in students.

(1) Background: Physical inactivity is a major public health problem that affects a significant number of adolescents throughout the world. Attaining regular physical activity is a major challenge for adolescents who study full-time. This study aimed to examine the associations between barriers to physical activity, physical activity levels, and time exposed to sedentary behavior during the coronavirus 2019 (COVID-19) pandemic among adolescent full-time students at an institute of professional and technical education. (2) Methods: We employed mixed methods in this case study, which enrolled 119 adolescent students (52.9% of whom were female). More specifically, we applied the Barriers to Physical Activity Questionnaire and the International Physical Activity Questionnaire and conducted semi-structured interviews. Our statistical analysis was based on Poisson regression with robust variance, and our qualitative analysis was based on content analysis. (3) Results: The adolescents frequently presented with a “low” level of physical activity (44.4%, n = 52). The following barriers were associated with a low level of physical activity: lack of time (prevalence ratio (PR) 1.546; confidence interval (CI) 1.111–2.151), lack of motivation (PR 1.573; CI 1.102–2.245), preference for other activities (PR 1.521; CI 1.073–2.155), lack of facilities close to home (PR 1.576; CI 1.077–2.307), laziness (PR 1.463; CI 1.031–2.076), and no way of getting to a facility (PR 1.619; CI 1.005–2.606). (4) Conclusions: We observed that physical activity barriers in the psychological, cognitive, emotional, and environmental dimensions were associated with low levels of physical activity. The students reported that full-time study was a barrier to physical activity that contributed negatively to their physical activity levels and time exposed to sedentary behaviors.

Back pain is a public health problem that affects adolescents and adults worldwide. However, studies on back pain present inconsistent findings in part due to the use of different instruments, especially for athletes. Therefore, the objective of this systematic review protocol was to map the existing evidence on such tools. The systematic review will be conducted according to PRISMA guidelines. Five electronic databases, Embase, MEDLINE, SPORTDiscus, CINAHL, and Scopus will be searched. This review includes studies that investigated prevalence, incidence, and other variables. Titles and abstracts will be selected. Two independent reviewers will read the articles carefully and discrepancies, if any, will be dealt with by a third reviewer. All steps will be completed with Rayyan for systematic reviews and the methodological quality will be analyzed with a COSMIN checklist. Discussion: This systematic review will gather evidence on tools that assess back pain in athletes. The findings may indicate the most appropriate tools for assessing back pain. They will contribute to better reliability, safe measurements, and help to standardize a comparison tool between different studies. They will also assist in the development of specific tools for athletes. Registration: This review was submitted and registered under CRD42020201299 in PROSPERO.

Introduction: Musculoskeletal disorders play an important role in athletes’ health and success in sports; they are the main contributors to disability, and back pain is a common problem in athletes. Back pain and spinal injuries occur in players because of the repetitive and unilateral body overload during sports practice. Reviews focused on musculoskeletal disorders in basketball players are scarce in the literature. We describe a systematic review protocol for assessing the prevalence of musculoskeletal disorders and the associated factors in basketball players. Methods and analysis: The protocol will be based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) items and articles will be searches in the databases EMBASE, PubMed, and Scopus. Studies will be included if they are written in English and without restriction regarding the search period. All research stages will be performed by two independent reviewers and will be conducted using Rayyan. Potential disagreements will be analyzed by a third reviewer. The inter-rater reliability will be determined through the Cohen's kappa coefficient. Evidence quality will be ascertained by using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system, while the Downs and Black checklist will be used for assessing the risk of bias. A descriptive summary and presentation of the characteristics and findings of all included studies will be provided in a table. Regarding these data, if there are sufficient high-quality studies, we plan to perform a meta-analysis. Discussion: The obtained results might possibly relate back pain to postural changes in this population. In addition, the data will be compared based on gender and different age groups. It is expected that the results can support the implementation of programs and actions for prevention, ultimately aiming at improving health, quality of life, and sports performance.

Resumo: Com o objetivo de avaliar as principais temáticas relacionadas às pesquisas que envolvem a Educação Física do ensino médio integrado no Brasil, este estudo foi feito a partir de uma revisão bibliográfica das publicações científicas nos programas de Pós-Graduação stricto sensu e de artigos científicos. O levantamento de teses e de dissertações utilizou como fonte a Biblioteca Digital Brasileira de Teses e Dissertações (BDTD). A busca de artigos científicos foi feita a partir da base de dados Scielo. Os estudos selecionados compreendem as publicações entre os anos de 2012 a 2019 e apresentam temáticas que se referem ao histórico da Educação Profissional dos Institutos Federais, ao histórico da Educação Física e sua relação com a Educação Profissional e Tecnológica, à análise da Educação Física na dinâmica curricular e às propostas de práticas pedagógicas para o ensino médio integrado. Constatamos que a baixa quantidade de produção científica pode levar ao entendimento da necessidade de maior discussão e pesquisa em relação à temática. Portanto, sugerimos que as pesquisas futuras apresentem propostas didático-pedagógicas que contribuam com a prática docente na Educação Física do ensino médio integrado. Palavras-chave: Educação física. Ensino médio integrado. Estado da arte. Educação integrada. Educação profissional.

The objectives of this study were to analyze and identify probable relationships between sedentary behavior and physical inactivity in children and adolescents, with the predominance of the Cartesian body concept in the school environment and the lack of learning about sports culture in Physical Education classes in elementary school. The research was based on a qualitative transversal approach with the participation of 19 students aged between 14 and 17 years, both sexes. The information collection instrument – questionnaire – discursive question submitted to the adapted technique of discourse analysis. It was identified that the devaluation of sports culture, which are apparently physical activities, in the school environment from the predominance of Cartesian conception of the body and the absence of access and appropriation of sports culture during Physical Education classes can contribute to sedentary behavior and inactivity. physical activity of children and adolescent students.

The objective of this study was to evaluate whether exposure to information about physical activity and its barriers can increase the level of physical activity and reduce the time exposed to sedentary behaviors in high school students involved in integrated professional and technological education during the coronavirus disease 2019 pandemic. This quasi experimental study was conducted with integrated education high school students, divided into two groups: Intervention Group (IG; n = 59) and Control Group (CG; n = 54). Physical activity and sedentary behavior were identified and measured using the International Physical Activity Questionnaire pre-and post-intervention for both groups. IG students received educational material thrice a week for four weeks. The focus of the material was the importance of physical activity and need to reduce the time exposed to sedentary behavior. The results revealed that IG students showed an average daily reduction of 47.14 min in time exposed to sedentary behaviors, while the CG students showed an increase of 31.37 min. Despite this, the intervention was not effective in improving physical activity levels in the IG and the mean reduction in the time exposed to sedentary behavior was not significant (p = 0.556). The intervention was ineffective in increasing the practice of physical activity and reducing the time exposed to sedentary behavior.
