Functional Ability of Cardiovascular System in Adolescents / Funkcionalna sposobnost kardiovaskularnog sistema kod adolescenata

Testing function of cardiovascular system is measured, the most often, physical ability and functional capacity of transport system or its parts. Many studies have found an association with obesity by reducing functional capacity of cardiovascular system that is correlated with physical ability to work. This research was conducted in order to determine the functional ability of cardiovascular system in adolescents to assess need of their sports activities at this age. The sample consisted of 55 high school students, male, 16 years old (+/- 6 months). For this research, the body mass index is used as a criterion for forming groups of respondents. The functional capacity of cardiovascular system is observed through variables: systolic and diastolic blood pressure before and after load and heart rate before and after load after performing Astrand test of ergometar bicycle. Analysis of functional abilities cardiovascular respondents before and after load, it was noted that in respondents who had a higher body mass index, showed higher values of systolic and diastolic blood pressure before and after load, as well as higher values of heart rate before and after load. This study confirmed previous numerous studies, stating that increased body mass index leads to harmful effects on cardiovascular system.
