The effects of playing time on performance changes were examined in National Collegiate Athletic Association Division I women basketball players. Twelve basketball players (age = 20.6 ± 1.5 years; height = 178.0 ± 8.2 cm; weight = 74.1 ± 8.1 kg) were assessed before (PRE) and at the end of the regular basketball season (POST). Assessments included squat power; vertical jump (VJ) power; 20-second lower-body reaction test; 3 line drills; and subjective measures of energy, focus, fatigue, and alertness. Pre- to postseason comparisons were made between starters (28.3 ± 5.2 minutes per game) and nonstarters (NSs) (8.3 ± 5.3 minutes per game). Data were analyzed for clinical significance using an approach based on the magnitude of change. Results revealed that starters were likely to have greater increases in absolute VJ peak power and relative VJ peak power (87.9 and 90.7%, respectively) and they were likely (81.6%) to have a greater average squat power than NSs. Subjective measures of energy, focus, and alertness were possibly (72.9%), very likely (97.3%), and likely (79.2%) to be lower in starters compared with NSs, respectively. Other performance measures showed unclear differences between starters and NSs. Pearson's product-moment correlation analysis revealed significant (p < 0.05) inverse correlations between playing time and Δ focus (r = -0.79) among all players. In conclusion, significant improvements in VJ performance and average squat power were seen in starters compared with NSs, despite greater decreases in energy, focus, and alertness. In this study, the monitoring of sport-specific performance changes pre and post season showed that performance measures can be maintained throughout an National Collegiate Athletic Association Division I women basketball season.
研究了比赛时间对全美大学生体育协会（NCAA）一级女子篮球运动员表现变化的影响。12 名篮球运动员（年龄=20.6±1.5 岁；身高=178.0±8.2cm；体重=74.1±8.1kg）在常规赛开始前（PRE）和结束时（POST）进行了评估。评估包括深蹲力量；垂直跳跃（VJ）力量；20 秒下肢反应测试；3 线训练；以及能量、专注、疲劳和警觉的主观测量。对首发球员（每场比赛 28.3±5.2 分钟）和非首发球员（每场比赛 8.3±5.3 分钟）进行了 PRE 到 POST 赛季的比较。结果显示，首发球员的绝对 VJ 峰值力量和相对 VJ 峰值力量可能会有更大的增加（分别为 87.9%和 90.7%），而且他们的平均深蹲力量可能（81.6%）高于非首发球员。首发球员的能量、专注和警觉的主观测量可能（72.9%）、极有可能（97.3%）和可能（79.2%）低于非首发球员。其他表现指标显示，首发球员和非首发球员之间的差异不明显。皮尔逊积差相关分析显示，所有运动员的比赛时间与 Δ专注（r=-0.79）之间存在显著（p<0.05）的负相关。结论是，与非首发球员相比，首发球员的 VJ 表现和平均深蹲力量有显著提高，尽管能量、专注和警觉性有所下降。在这项研究中，对赛季前和赛季后的特定运动表现变化的监测表明，在 NCAA 一级女子篮球赛季中，运动表现可以得到维持。
