In recent decades scientists have been showing more interest in researching how a human body changes while growing during childhood. It is obvious that prevention of functional and structural bodily disorders have to start in early school years. So far it is not fully explored why such changes occur during this period of life. The correct evaluation of the development of bone and muscle structure and of cardiovascular system, the early diagnosis of any deviations and employment of adequate measures of prevention of structural and functional changes are very important. The aim of the study is o investigate the correlation between structural and functional parameters of a growing body. Objectives: 1.To evaluate changes of structural and functional parameters in children and adolescents according to age. 2.To evaluate changes of structural and functional parameters in children and adolescents according to gender. 3.To determine age related correlations among structural and functional body parameters in children and adolescents. 4.To determine correlations among structural and functional body parameters in children and adolescents related to gender. MATERIALS AND METHODS: One hundred and twenty four school age children (aged 7-18 years) participated in the study. Methods: The bicycle (VEM) veloergometry test, ECG, ABP, HR measurements, dynamometry, cirtometry, scoliometry. Conclusions. Thoracic kyphosis in boys decreased with age. Parameters of body posture in frontal plane did... [to full text]
