Reference values of 6 minutes walk test (6 MWT) in Bangladeshi healthy subjects aged 25-55 years

Introduction: The six minute walk test (6MWT) is increasingly accepted worldwide to assess functional exercise capacity of cardiac and pulmonary diseases for its simplicity. Aims and objectives: The aim of the present study was to provide reference values for 6 Minute Walk Distance (6MWD) and other primary variables such as oxygen saturation (SaO2), pulse rate (PR) and breathlessness perception done in 6MWT. Methods: We studied a sample of 190 healthy subjects (53 females) of age between 25-55 years (37.9±8.5 years). Baseline lung functions including forced expiratory volume in 1 st second (FEV1), forced vital capacity (FVC) and FEV1/FVC ratio were measured by a flow sensing spirometer.
