随着校园篮球在全国范围内迅速开展，对CUBA联赛运动员的技战术水平要求不断提高。伴随篮球比赛重心由内向外和球场上位置模糊化的发展，对篮球后卫运动员的能力提出了更高要求，后卫作为球队场上“大脑”，领导着球队的进攻防守运转，需要具备更全面的技术和更强的身体素质。CUBA大学生联赛作为中国篮球的人才储备基地，近年来联赛也有越来越多优秀后卫进入CBA。同样为大学生联赛，如何使CUBA优秀后卫的能力向NCAA优秀后卫靠拢是本文研究的方向。本文以NCAA优秀后卫球员为参照，通过着重观察对比第21届CUBA和NCAA第2020-2021赛季优秀后卫的比赛录像、数据和球员身体指标以及进攻能力指标得出结论建议。将对比结果应用到CUBA后卫球员培养中，应用价值为为CUBA后卫球员的训练方向提供参考，以提高CUBA后卫球员的比赛水平。

研究对象：均为所选赛季排名前列球员，大部分已进入更高级的NBA或CBA联赛。

研究目的：以NCAA为参照系，找出CUBA优秀后卫与NCAA优秀后卫之间的差距与不足，依托篮球项目发展趋势为CUBA培养更多优秀后卫人才提供可靠依据。通过文献资料分析、数理统计分析和对比分析，本研究对NCAA和CUBA优秀后卫的身体特征、身体素质和克托莱指数进行了深入探究，以期获得更加准确的评估结果。

研究方法：文献资料法、录像观察法、对比分析法、数理统计法。

研究结果：1.在身体形态指标方面，NCAA优秀后卫球员体重和克托莱指数优于CUBA优秀后卫球员。2.在进攻能力指标方面，NCAA优秀后卫场均得分显著多于CUBA优秀后卫。3.NCAA优秀后卫场均罚球次数远多于CUBA优秀后卫球员。4.在场均得分数据方面，CUBA和NCAA优秀后卫所在球队场均得分具有显著性差异。NCAA优秀后卫场均得分明显高于CUBA优秀后卫，具有显著性差异。NCAA后卫球员得分占比显著高于CUBA优秀后卫球员。5.在出手次数占比方面，NCAA优秀后卫球员出手次数占比高于CUBA优秀后卫球员。6.在进攻方式选择方面，NCAA球员有更多中距离和个人突破，CUBA球员有更多突破和远距离投篮。

研究结论如下：1.在身体形态指标方面，NCAA与CUBA优秀后卫在身高指标上不存在显著差异。但体重和克托莱指数两项指标存在显著差异,NCAA优秀后卫身体质量更高，对抗力量更强，在面对更高强度比赛时能有更好的发挥。2.在进攻能力指标方面，CUBA优秀后卫球员得分与NCAA优秀后卫球员存在显著差异，抢断、助攻、失误方面都不存在显著差异。3.在持球突破方面，NCAA后卫球员更擅长用个人突破能力突破造杀伤。4.在场均得分数据方面，NCAA的比赛更为激烈，NCAA优秀后卫得分能力更强，NCAA球员在球队中更多扮演得分手的角色。5.在出手次数占比方面，NCAA后卫球员对球权有更多主导权。NCAA球队场均出手次数更少，对抗更为激烈。6.在进攻方式选择方面，NCAA优秀后卫球员会更多地选择中距离投篮、个人突破成功率较高。CUBA优秀后卫球员更倾向于突破和远距离投篮，中距离出手较少，在对抗后的突破成功率低。

With the rapid development of campus basketball in the whole country, the technical and tactical level of CUBA league players is constantly raised. With the development of the center of gravity of basketball game from inside-out and the blurred position on the court, higher requirements are put forward for the ability of basketball guard players.

As the talent reserve base of CUBA college basketball, more and more outstanding guards have entered CBA in recent years. It is also a college league, so how to make CUBA excellent guards close to NCAA excellent guards is the research direction of this paper. Taking NCAA outstanding guard players as reference, this paper draws conclusions and suggestions by focusing on observing and comparing the match videos, data, players' physical indicators and offensive ability of outstanding guard players in CUBA 21 and NCAA 2020-2021 seasons. The comparison results are applied to the training of CUBA fullback players, and the application value provides reference for the training direction of CUBA fullback players, so as to improve the competition level of CUBA fullback players.

Research Objective: To find out the gap and deficiency between excellent guards in CUBA and NCAA, and to provide a reliable basis for cultivating more excellent guards in CUBA based on the development trend of basketball programs. Through literature analysis, mathematical statistics analysis and comparative analysis, this study conducted in-depth research on the physical characteristics, physical quality and Ketolet index of outstanding guards in NCAA and CUBA, in order to obtain more accurate evaluation results.

Research methods: literature, video observation, comparative analysis, mathematical statistics.

Results: 1. In terms of body shape, the weight of NCAA elite linebackers and Ketolet index are better than those of CUBA elite linebackers. 2. In terms of offensive ability, NCAA elite guards scored more points per game than CUBA elite guards. 3. Elite NCAA guards shoot more free throws per game than elite CUBA guards. 4. There is a significant difference in points per game between CUBA and NCAA elite guard teams.
