OBJECTIVES To compare the physical performance and responses obtained in the six-minute walking test (6MWT) and the six-minute step test (6MST) between asthmatic and healthy adolescents; and to investigate the relationship between the responses obtained in the tests and the body mass index (BMI), physical activity level and spirometric variables. METHODS Nineteen asthmatic adolescents (AG) an...

BACKGROUND This study aims to explore the relationship between serum vitamin A and 25-hydroxyvitamin D3 (25OHD3) levels with pulmonary function and quality of life (QOL) in children with stable asthma. METHODS A total of 117 cases of children with stable asthma were assigned into the case group and 129 healthy children underwent physical examination during the same period into the control gro...

A review of the characteristics of hydrogen as an inert gas for use in diving is presented, with special emphasis on the extention of the respiratory limitation in diving by use of this least dense of all gases. Forced vital capacity (FVC), forced expiratory volume in one second (FEVi), forced expiratory volume in two seconds (FEV2). peak expiratory flow rate (PEFR), peak inspiratory flow rate ...

INTRODUCTION Spirometry should follow strict quality criteria. The American Thoracic Society (ATS) recommends the use of a noseclip; however there are controversies about its need. ATS also indicates that tests should be done in the sitting position, but there are no recommendations neither about position of the upper limbs and lower limbs nor about who should hold the mouthpiece while performi...

BACKGROUND Sickle Cell Disease (SCD), which is characterized by a mutation in the gene encoding beta hemoglobin, causes bodily dysfunctions such as impaired pulmonary function and reduced functional capacity. OBJECTIVE To assess changes in pulmonary function and functional capacity in patients with SCD and to identify the relationships between these variables. METHOD We evaluated sociodemog...
