The exercise performance analysis of students with connective tissue dysplasia, players of male and female basketball teams of the Ural Federal University

Investigation of connective tissue dysplasia (CTD) role in the forming of cardiovascular system (CS) adaptive abilities to the physical load in young athletes. Thirty students (mean age19,6 ± 3,14), members of male (11 athletes) and female (19) basketball teams of UrFU under-went the maximum exercise performance treadmill-test. According to the echocardiography data, all athletes had the false tendons in left ventricle as a cardiac phenotypic manifestation of CTD. The extent of CTD development was assessed by hypermobility of joints with use the Beighton scale. CS response to the stress-test was evaluated by heart rate and blood pressure changes and further calculations of standard indices of cardiac functional reserve. We found that young basketball-players with CTD had satisfactory level of exercise performance, though maximum work efficiency of male athletes was significantly higher (16,7 ± 1,9 METs), than female ones (15,1 ± 1,5 METs). At the same time, the CS adaptive source appeared to be at significantly higher level in male athletes. Based on the significant correlations between the CTD Beighton index and a number of CS reserve indices, we concluded that the lower the extent of CTD development, the higher the CS adaptive abilities of young basketballplayers with CTD.
