Creatine monohydrate (CrM) supplementation has been shown to be an effective and safe nutritional supplement to improve performance; however, the impact of CrM supplementation in young basketball players is less clear. This study evaluated the effects of CrM supplementation during a strength and conditioning training (SCT) program on lower-limb strength parameters and performance in under-16 (U16) basketball players.
Twenty-three male U16 basketball players participated in this study (14.3 ± 0.4 years; BMI: 20.7 ± 2.2 kg∙m). The players were randomly assigned to either a CrM group ( = 12) that ingested 0.1 g·kg·day of CrM or to a non-supplemented control group ( = 11, CON). The athletes participated in an 8-week SCT program consisting of two lower-limb resistance-training sessions and two plyometric sessions per week. Squat jump (SJ), drop jump (DP), countermovement jump (CMJ), and Abalakov (ABK) jump power tests as well as basketball performance (points and minutes per game) were measured before, during and/or after the intervention. Data were analyzed using a general linear model with repeated measures with independent Student's t-test pairwise comparisons.
The results (95% confidence interval for mean change from baseline) show that there were significant differences for all variables for CrM and CON, respectively: SJ (cm): 2.6 - 6.4, P < 0.01 and 2.2-5.1 P < 0.01; DJ (cm): 2.5-5.6, P < 0.01, and 1.8-4.4, P < 0.01; CMJ (cm): 0.3-0.8, P < 0.01, and 0.2-0.5, P < 0.01; ABK (cm): 2.8-5.5, P < 0.01 and 0.7-2.6, P = 0.003. A significant group x time interaction ( = 0.003, = 0.342) was observed in ABK performance. No significant group x time effects were seen in squat jump ( = 0.449, = 0.028), drop jump ( = 0.143, = 0.099), or counter movement jump ( = 0.304, = 0.05). A significant interaction effect was also observed in points per game ( = 0.049, = 0.149), while a non-significant but medium effect was seen in minutes per game ( = 0.166, = 0.094).
CrM supplementation in conjunction with resistance and plyometric training increased the lower-limb ABK power and scoring performance in U16 basketball players.
肌酸一水合物（CrM）补充已被证明是一种有效且安全的营养补充剂，可以提高运动表现；然而，CrM 补充对年轻篮球运动员的影响尚不清楚。本研究评估了在力量和体能训练（SCT）计划期间补充 CrM 对 16 岁以下（U16）篮球运动员下肢力量参数和表现的影响。
23 名 U16 男性篮球运动员参加了这项研究（14.3±0.4 岁；BMI：20.7±2.2 kg·m）。运动员被随机分配到 CrM 组（n=12）或非补充对照组（n=11，CON）。运动员参加了为期 8 周的 SCT 计划，每周进行两次下肢抗阻训练和两次增强式训练。在干预前后测量了深蹲跳（SJ）、跳深（DP）、纵跳（CMJ）和阿巴洛夫（ABK）跳跃力量测试以及篮球表现（每场比赛的得分和分钟数）。数据采用重复测量的一般线性模型进行分析，并采用独立学生 t 检验进行两两比较。
结果（均值变化的 95%置信区间，与基线相比）显示，CrM 和 CON 组的所有变量均有显著差异：SJ（cm）：2.6-6.4，P <0.01 和 2.2-5.1 P <0.01；DJ（cm）：2.5-5.6，P <0.01，1.8-4.4，P <0.01；CMJ（cm）：0.3-0.8，P <0.01，0.2-0.5，P <0.01；ABK（cm）：2.8-5.5，P <0.01 和 0.7-2.6，P=0.003。在 ABK 表现方面观察到显著的组间 x 时间交互作用（=0.003，=0.342）。在深蹲跳（=0.449，=0.028）、跳深（=0.143，=0.099）或纵跳（=0.304，=0.05）方面未观察到显著的组间 x 时间效应。在每场比赛的得分方面也观察到显著的交互作用效应（=0.049，=0.149），而在每场比赛的分钟数方面则观察到非显著但中等效应（=0.166，=0.094）。
CrM 补充结合抗阻和增强式训练可提高 U16 篮球运动员的下肢 ABK 力量和得分表现。
