This paper investigated the impact of eye-closed and weighted training (EWMT) on the stroke effect of adolescent table tennis players. Forty-eight adolescent table tennis players were randomly selected from the China Table Tennis College and were divided into two groups as 1) the experimental group (EG, n = 24) in which they engaged in multi-ball exercise with eye-closed and weighted swing for 10 weeks, and 2) the control group (CG, n = 24) in which they received a normal training without eye-closed and weighted swing intervention. The stroke effect was assessed by three outcome measures: accuracy, stability, and ball speed. Results showed that 1) both the traditional training method and EWMT can improve the stroke effect of adolescent table tennis players. 2) In terms of accuracy, the number of stroke in the corner area was significantly different between EG and CG after the experiment (p = 0.022, p < 0.001, respectively). 3) In terms of stroke stability, there was a significant difference in the number of net ball strokes between EG and CG after the experiment (p = 0.014). 4) In terms of ball speed, there was no significant difference between EG and CG after the experiment (p = 0.871). 5) After EWMT, the stroke stability of backspin had more significant improvement than that of topspin. Thus, compared with the traditional training method, the EWMT method can improve the stroke effect of adolescent table tennis players in terms of accuracy and stability more significantly; the EWMT method can improve the stroke effect of backspin more significantly than that of topspin in terms of stability.
本文研究了闭眼加负重训练（EWMT）对青少年乒乓球运动员击球效果的影响。从中国乒乓球学院随机抽取 48 名青少年乒乓球运动员，分为实验组（EG，n=24）和对照组（CG，n=24）。实验组采用闭眼加负重挥拍多球练习，进行 10 周训练，对照组采用正常训练，不进行闭眼和负重挥拍干预。通过三个结果衡量指标评估击球效果：准确性、稳定性和球速。结果表明：1）传统训练方法和 EWMT 均可提高青少年乒乓球运动员的击球效果；2）在准确性方面，实验后 EG 和 CG 在击球进角区的次数上存在显著差异（p=0.022，p<0.001）；3）在稳定性方面，实验后 EG 和 CG 在击球触网次数上存在显著差异（p=0.014）；4）在球速方面，实验后 EG 和 CG 之间没有显著差异（p=0.871）；5）进行 EWMT 后，下旋球的击球稳定性有了更显著的提高，比上旋球更显著。因此，与传统训练方法相比，EWMT 方法在准确性和稳定性方面能更显著地提高青少年乒乓球运动员的击球效果；在稳定性方面，EWMT 方法比传统训练方法能更显著地提高下旋球的击球效果，而上旋球的效果改善则不明显。
