Considering the importance of physical activity and, specifically, the insufficient levels of physical activity in the adolescent population, the question of the levels of physical activity performed by high school students in subsidized private schools in the district of Talcahuano during the period of confinement was raised. Method: 152 males and 177 females between 14 and 17 years of age from three subsidized private schools in the municipality of Talcahuano were evaluated. A digital questionnaire was administered on the day of distance learning. Results: The mean questionnaire score was 2.37 ± 0.68. The obtained score classified the students as inactive since they had values lower than 2.75 on the PAQ-A questionnaire. Mann-Whitney U test was performed to determine the differences in median questionnaire scores for male and female groups. The median was statistically significant between the groups p= 0.001. A Kruskal-Wallis test was performed to compare the age groups. As a result, the median was not significantly different between age groups, P = 0.224. Conclusion: men are, on average, more physically active than women, and there is no difference in the median age between 14 and 17 years in the confinement periods., Introdução: devido à pandemia mundial causada pela SARS-CoV-2 (COVID-19), as autoridades optaram por confinar seus cidadãos como medida de contenção epidemiológica, reduzindo consideravelmente os níveis de atividade física na população adolescente.

The perception of the physical education class by the students is an important factor because depending on how the students perceive these experiences, certain beliefs or evaluations will be generated, which influence the attitude to face these bodily experiences each time they To present themselves. 176 students (14.74 ± 0.68), belonging to private subsidized establishments in the Coronel commune.

In the comparative analysis between men and women for the positive perception I report (p = 0.63) and negative (p = 0.10). In the analysis by age for the positive scale (p = 0.01), for the negative scale (p = 0.25). The students observed mostly positive attitudes and very few negative ones in the physical education teacher, without observing differences between men and women, in the ages differences were reported in the positive and negative attitudes of the teacher, informing that the students with more age more critically evaluate the positive and negative attitudes of the PE teacher., La percepción de la clase de educación física por parte de los estudiantes es un factor importante porque dependiendo de cómo los escolares perciban estas vivencias, se generarán determinadas creencias o valoraciones, las que influyen en la actitud para enfrentar estas experiencias corporales cada vez que se presenten. 176 estudiantes (14.74 ± 0.68), pertenecientes a los establecimientos particulares subvencionados de la comuna de Coronel.

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that negatively affects the inattention, disorganization, and/or hyperactivity–impulsivity in children and adolescents who suffer from it, included cases being reported that continue into adulthood. This disorder impairs social, academic, emotional, psychological, and health system functioning due to its high cost of treatment. The present systematic review aims to analyze the effects of physical activity, exercise, and sports on the executive function in children and adolescents diagnosed with ADHD through the scientific literature. The results show that the practice of physical activity, exercise, or sport produces improvements in executive function in children and adolescents diagnosed with ADHD, mainly through aerobic exercise. A 20 min session of physical activity, sport, or exercise leads to improvements in executive functions in children and adolescents with ADHD. It can be concluded that the practice of physical activity, exercise, and sport generate improvements on executive functions in children and adolescents with ADHD, mainly through aerobic exercise.
