<abstract xmlns="http://www.w3.org/1999/xhtml"><bold>Aim</bold>: The aim of this study was to determine and analyse the relations between anthropometric parameters, red blood cells’ (RBC) variables and cardio-physiological parameters in healthy and physically active children and adolescents.<bold>Material and Methods</bold>: In this study 625 subjects, (410 males and 215 females; age span 8 to 18 years) underwent body composition analysis (Matiegka method), blood analysis and ergometry testing (Bruce protocol).<bold>Results</bold>: In both groups, body height and weight were positively correlated with RBC variables.
