BACKGROUND/OBJECTIVE: 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 13-18 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%; = 0.24) and without dribbling (intraclass correlation coefficient = 0.83; coefficient of variation = 15.0%; = 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 ± 417 m vs. 910 ± 299 m, < 0.01; = 0.65), as well as in the entire study sample (1077 ± 398 m vs. 1267 ± 437 m, < 0.05; = 0.45), whereas there was no significant difference in the senior players between the two protocols (1396 ± 436 m vs. 1244 ± 427 m, > 0.05; = 0.35). Moderate to large correlations were found between running and dribbling performances in the senior sample ( = 0.57, = 0.06), the junior sample ( = 0.87, < 0.01), and the whole ( = 0.72, < 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.
背景/目的:本研究旨在探讨Yo-Yo测试成绩能否反映青少年篮球运动员高强度间歇性运球的重复性。
邀请36名年龄在13 - 18岁的青少年篮球运动员参与本研究。
重测结果显示,有运球的Yo-Yo间歇性耐力二级(IE2)测试(组内相关系数 = 0.92;变异系数 = 12.6%;P = 0.24)和无运球的Yo-Yo间歇性耐力二级(IE2)测试(组内相关系数 = 0.83;变异系数 = 15.0%;P = 0.37)具有可接受的可靠性。在15岁以下的参与者(青少年组;1138 ± 417米 vs. 910 ± 299米,P < 0.01;r = 0.65)以及整个研究样本(1077 ± 398米 vs. 1267 ± 437米,P < 0.05;r = 0.45)中,运球覆盖的距离明显短于Yo-Yo IE2测试的跑步成绩,而在成年球员中,两种测试方案之间没有显著差异(1396 ± 436米 vs. 1244 ± 427米,P > 0.05;r = 0.35)。在成年样本(r = 0.57,P = 0.06)、青少年样本(r = 0.87,P < 0.01)和整个样本(r = 0.72,P < 0.01)中,跑步和运球成绩之间分别发现了中度到高度的相关性。
结果表明,Yo-Yo IE2测试可以反映高强度间歇性篮球运球表现的重复性,而运球技巧可能对不同年龄段的青少年球员的高强度间歇运动能力有不同影响。
