(三)YO-YO 跑测 试成绩与运球 YO-YO 跑测试成绩高度显著相关.受试者的篮球球性对运球 YO-YO 跑的测试成绩有一定的影响;

(四)以YO-YO 跑测试距离、脂肪百 分比为变项,可预测最大摄氧量,公式为最大摄氧量 = 53.585- 0.287 *脂肪 百分比+ 0.005 *YOYO 跑测试距离.此公式能解释 52.4%最大摄氧量的变异 量,能较为有效地预测最大摄氧量. 关键词:最大摄氧量、YO-YO跑测试成绩、运球YO-YO跑测试成绩、 脂肪百分比 IV Abstract Objective: The purpose of this research to explore the relationships among VO2max, the performance of Yo-Yo Intermittent Endurance Test (YO-YO), the result of Yo-Yo dribbling modified test and body composition in male high school basketball players. Methodology:

26 male basketball players, aged

13 to 18, from a Macau high school were invited to participate in this study and

22 subjects completed all the tests, which included twice 20-m YO-YO test, twice 17.5-m YO-YO dribbling modified test, in the sports field in that school. All the subjects wore Zephyrs heart monitors during each testing period and the parameters such as heart rate, the rating perceived exertion (RPE), the distance (DYO-YO) and velocity (VYO-YO) of the shuttle runs, and the dribbling distance (Ddribbling) and velocity (dVYO-YO) of modified YO-YO test were recorded. In addition, VO2max was measured using graded exercise testing (GXT) on a high-speed treadmill in lab. Result: Test-retest reliability of DYO-YO and Ddribbling were.71 (p< .05) and .67 (p< .01) respectively. VO2max had moderate correlations with DYO-YO(r = .64, p< .01) , VYO-YO (r = .67, p< .01) , Ddribbling (r = .52, p< .05) , dVYO-YO (r = .51, p< .05)and body fat percentage(r = -.59, p< .01)respectively. Maximal pulmonary ventilation volume had a significantly negative correlation with fat V percentag (r = -.47, p< .05). Dribbling were highly correlated with DYO-YO (r = .78, p< .01)and VYO-YO (r = .76, p< .01), while dVYO-YO had high correlations with DYO-YO (r = .80, p< .01) and VYO-YO(r = .78, p< .01). Conclusion: (i) The reliability of test-retest of YO-YO endurance and dribbling YO-YO modified test can be accepted. (ii)VO2max are moderately correlated with the performances of YO-YO and dribbling YO-YO modified test, and body fat percentage. The performances of YO-YO and dribbling YO-YO modified test had no significant correlations with maximal pulmonary ventilation volume. (iii) High correlations were found between the performance of YO-YO test and the results of dribbling YO-YO modified test. (iv) The distance of YO-YO endurance test and body fat percentage could predict the VO2max. The regression formula, is VO2max = 53.585- 0.287* boy fat percentage + 0.005 * DYOYO, and it can explain 52.4% variance of VO2max. Key words: VO2max, YO-YO endurance test, dribbling YO-YO modified test, body fat percentage VI 目录第壹章 绪论
