Abstract :
Objective: This study aimed to determine the effect of single-bout exercise on aortic stiffness parameters in young basketball players.
Method and results: A total of 108 young male subjects (mean age 14.2 ± 3.4 years) were enrolled into the study. Simultaneous measurement of aortic pulse wave velocity (PWVao) and augmentation index (AIxao) were performed with the oscillometric, occlusive device. Echocardiographic parameters of left ventricular systolic and diastolic function at rest were also measured in sportsmen. We did not find significant differences of resting PWVao in comparison with young sportsmen (S) and age-matched healthy volunteers (V): 5.82 ± 0.14 m/s vs 5.83 ± 0.12 m/s for S and V groups, respectively. The values of PWVao measured after dynamic exercise, isometric exercise, and rest were 8.0 ± 0.5 m/s, 5.86 ± 0.1 m/s and 5.82 ± 0.1 m/s, respectively. We confirmed that values after dynamic exercise are significantly different from those after isometric exercise (P < 0.01) and those after rest (P < 0.01). The AIxao values exhibited a considerable, but statistically non-significant, decrease during dynamic exercise in the three groups (11.7 ± 7% vs 3.8 ± 3% vs 0.9 ± 0.9% for groups 1, 2, and 3, respectively).
Conclusion: We applied a feasible, clinically useful method which allowed us to measure changes in aortic PWV and AIx during acute, single-bout exercise on the basketball court in young sportsmen.
