RESUMO
Background & objectives : The deleterious effects of obesity on cardiovascular system have been well documented but their effects on the respiratory system and aerobic capacity have been overlooked. Thus this study was planned to assess ventilatory lung function tests and aerobic capacity in overweight young adults. Material and Methods: A total of 60 young students (18 to 22 years) were recruited in this study. They were divided in to 2 groups. Overweight group and control group. Pulmonary function tests (static and dynamic) were recorded on a computerized portable Schiller lung function unit. Aerobic capacity (VO2 max) was estimated by Queen’s College Step test. Data was analyzed by Students ‘t’ test. Results : In overweight group expiratory reserve volume , forced vital capacity, maximum ventilatory volume, forced expiratory volume at the end of first second and VO2 max were reduced as compared to control group. Interpretation and conclusion: These results indicate that increase in BMI may affect ventilatory lung function tests and aerobic capacity in young adults.
