Resumo
Introduction: There are some immediate benefits that the practice of physical activity can
bring to children and adolescents, one of them being the physical aptitude related to health.
Among these benefits we can highlight improvements in flexibility, muscular strength and
cardio respiratory fitness. Despite the benefits the practice of physical activity brings to
health, many studies have demonstrate that the percentage of young people whit insufficient
levels of physical activity is high. From projects within the physical education classes and
extracurricular activities, the schools can play an important role in creating healthy habits and
improving adolescent’s cardio respiratory fitness. However, although school-age adolescents
may be involved in some kind of physical activity during classes, this does not guarantee they
may be experiencing physical efforts adequate intensities and periods of time sufficient to
induce physiological adaptations to focused on healthy. Objective: To compare the
anthropometric variables and cardiopulmonary responses among school-age adolescents who
practice physical education and those who, together with this activity, are part of the sports
training program offered by the school. Methods: A cross-sectional study with 21 non-athlete
adolescents (12 girls and 9 boys) and 24 athletes (8 girls and 16 boys), aged 14 to 15 years.
Beyond cardiopulmonary fitness, adolescents were submitted to weight, height, fat
percentage, physical activity level, sexual maturation and flexibility test. The
cardiopulmonary exercise test was performed on an ergometric treadmill (Inbrasport Super
ATL, Rio Grande do Sul, Brazil), using the Metalyzer 3B Cortex gas analyzer. Statistical
analysis was used Student's t-test for comparisons between groups, and the statistical
significance was p <0.05. Results: No significant differences were found between the athlete
and non-athlete groups for the anthropometric variables, regardless of sex. However, the
group of male athletes presented better VO2 máx. results. When compared to the non-athlete
group, the same did not occur with the girls. Conclusion: It was concluded that only the boys
from the Athlete Group had higher cardiorespiratory fitness when compared to the Group of
non-athletes, suggesting the influence of the sports training on the results.
