CrossFit™ (CF) training has gained popularity as a high-intensity functional training method, but its effectiveness in youth sports remains underexplored. This study examined the impact of CF on the physical fitness and basketball-specific skills of U12 athletes. The objective was to compare the effects of CF training versus regular training on physical performance and basketball-related abilities in U12 basketball players.
A randomized controlled trial was conducted involving 40 male U12 basketball players. Participants were randomly assigned to either an experimental group (CF, n = 20) or a control group (regular training, n = 20) for 8 weeks, with 4 sessions per week. Pre- and post-intervention assessments included pushups, seated forward bend, standing long jump (SLJ), full-court dribble to layup, 1-minute shooting, 3/4 court sprint (sprint), and a 4-line shuttle run.
The experimental group demonstrated significant improvements in pushups (T = -4.158, P < .001), SLJ (T = -10.228, P < .001), sprint (T = 2.121, P = .047), full-court dribble to layup (Z = -3.921, P < .001), and 1-minute shooting (T = -2.373, P = .028). The control group showed modest improvements only in the sprint and SLJ. No significant changes were observed in seated forward bend performance in either group.
CF training was more effective than conventional methods in enhancing physical fitness and sport-specific skills among U12 basketball players. These findings support the integration of CF into youth basketball programs to promote athletic development.
CrossFit™（CF）训练作为一种高强度功能性训练方法已广受欢迎，但它在青少年体育运动中的有效性仍未得到充分研究。本研究考察了CF对12岁以下运动员身体素质和篮球专项技能的影响。目的是比较CF训练与常规训练对12岁以下篮球运动员身体表现和篮球相关能力的影响。
进行了一项随机对照试验，纳入40名12岁以下男性篮球运动员。参与者被随机分为实验组（CF，n = 20）或对照组（常规训练，n = 20），为期8周，每周训练4次。干预前后的评估包括俯卧撑、坐位体前屈、立定跳远（SLJ）、全场运球上篮、1分钟投篮、3/4场冲刺跑（冲刺）和四线穿梭跑。
实验组在俯卧撑（T = -4.158，P <.001）、SLJ（T = -10.228，P <.001）、冲刺跑（T = 2.121，P =.047）、全场运球上篮（Z = -3.921，P <.001）和1分钟投篮（T = -2.373，P =.028）方面有显著改善。对照组仅在冲刺跑和SLJ方面有适度改善。两组坐位体前屈表现均未观察到显著变化。
在提高12岁以下篮球运动员的身体素质和专项运动技能方面，CF训练比传统方法更有效。这些发现支持将CF纳入青少年篮球项目以促进运动发展。
