The Effect of Exercise on Adolescent Lung Function Performance: An Observational Study in the Adolescent Community in Jakarta, Indonesia

Optimal lung function is a crucial health indicator, especially in adolescents who are in the growth and development phase. Exercise is known to have a positive impact on lung function, but research evidence on adolescents in Indonesia, especially Jakarta, is still limited. This study aims to examine the effect of exercise on the lung function performance of adolescents in Jakarta, considering the urban context with high levels of air pollution. This cross-sectional observational study involved 350 adolescents aged 12-18 years in Jakarta, randomly selected from various schools. Data collection included a physical activity questionnaire (IPAQ short version), anthropometric measurements (height, weight, waist circumference), and spirometry to assess lung function (FEV1, FVC, FEV1/FVC). Multiple linear regression analysis was used to identify associations between exercise and lung function parameters, with adjustment for confounding factors. The results showed that physically active adolescents had significantly higher FEV1, FVC, and FEV1/FVC values compared to less active adolescents (p < 0.001). These results remained significant after adjusting for age, gender, body mass index (BMI), and smoking status. There was no significant relationship between age and lung function parameters. Adolescent boys have higher FEV1, FVC, and FEV1/FVC values than girls. Height and weight are positively correlated with FEV1 and FVC. Exercise has a significant positive effect on the lung function performance of adolescents in Jakarta. These findings support the importance of promoting physical activity in adolescents to improve lung health, especially in urban environments with exposure to air pollution. Further longitudinal studies are needed to confirm these findings and evaluate the long-term effects of exercise on adolescent lung function.
