The primary objective of this study is to investigate the maintenance difference in basic anthropometric characteristics
and to outline the dynamics of respiratory function change in youngsters athletes exposed to passive smoking (PS)
and athletes not exposed to passive smoking in their families (NPS). High and weight were determined as basis anthropometric
characteristics. Measured parameters for respiratory function were vital capacity (VC), forced expiratory
volume in the first second (FEV1), maximum expiratory flow (PEF), forced expiratory flow at 50% forced vital capacity
(MEF 50) and forced expiratory flow at 25% forced vital capacity (MEF 25). Significant statistical differences in separate
spirometric variable were found in three variables (FEV1, MEF50, and MEF25) for group older youngsters. Analysis of
variance showed statistical differences between athletes unexposed to passive smoking (NPS) and athletes exposed to passive
smoking (PS) in even four spirometric variables (VC, FEV1, MEF50 and MEF25)
