This research examines whether or not the Yo-Yo testing performance could reflect the repeatability of high-intensity intermittent dribbling in adolescent basketball players.
Thirty-six teenage basketball players aged 13–۱۸ years were invited to participate in this study.
A test–retest showed that the Yo-Yo intermittent endurance Level 2 (IE2) test with dribbling (intraclass correlation coefficient = 0.92; coefficient of variation = 12.6%; d = 0.24) and without dribbling (intraclass correlation coefficient = 0.83; coefficient of variation = 15.0%; d = 0.37) had acceptable reliability. The dribbling distance covered was significantly shorter than was the running performance of the Yo-Yo IE2 test in participants younger than 15 years (junior; 1138 ± ۴۱۷ m vs. 910 ± ۲۹۹ m, p < 0.01; d = 0.65), as well as in the entire study sample (1077 ± ۳۹۸ m vs. 1267 ± ۴۳۷ m, p < 0.05; d = 0.45), whereas there was no significant difference in the senior players between the two protocols (1396 ± ۴۳۶ m vs. 1244 ± ۴۲۷ m, p > 0.05; d = 0.35). Moderate to large correlations were found between running and dribbling performances in the senior sample (r = 0.57, p = 0.06), the junior sample (r = 0.87, p < 0.01), and the whole (r = 0.72, p < 0.01) sample, respectively.
The results suggest that the Yo-Yo IE2 test could reflect the repeatability of high-intensity intermittent basketball dribbling performance, while dribbling skills may have different influences on high-intensity intermittent exercise capacity in adolescent players at different ages.
