The aim of this study was to compare the effects of two plyometric training techniques on power and agility in youth soccer players. Twelve males from a semiprofessional football club's academy (age = 17.3 +/- 0.4 years, stature = 177.9 +/- 5.1 cm, mass = 68.7 +/- 5.6 kg) were randomly assigned to 6 weeks of depth jump (DJ) or countermovement jump (CMJ) training twice weekly. Participants in the DJ group performed drop jumps with instructions to minimize ground-contact time while maximizing height. Participants in the CMJ group performed jumps from a standing start position with instructions to gain maximum jump height. Posttraining, both groups experienced improvements in vertical jump height (p < 0.05) and agility time (p < 0.05) and no change in sprint performance (p > 0.05). There were no differences between the treatment groups (p > 0.05). The study concludes that both DJ and CMJ plyometrics are worthwhile training activities for improving power and agility in youth soccer players.
本研究的目的是比较两种增强式训练技术对青少年足球运动员力量和敏捷性的影响。从一个半职业足球俱乐部青训营选取了12名男性（年龄 = 17.3 ± 0.4岁，身高 = 177.9 ± 5.1厘米，体重 = 68.7 ± 5.6千克），随机分为两组，分别进行为期6周的深度纵跳（DJ）训练或反向纵跳（CMJ）训练，每周训练两次。DJ组参与者进行下落纵跳，要求尽量缩短地面接触时间并尽量跳高。CMJ组参与者从站立起始位置起跳，要求尽量跳得最高。训练后，两组的垂直跳高（p < 0.05）和敏捷时间（p < 0.05）均有所改善，短跑成绩无变化（p > 0.05）。两组之间无差异（p > 0.05）。该研究得出结论，DJ和CMJ增强式训练都是提高青少年足球运动员力量和敏捷性的值得开展的训练活动。
