Improving lower extremity sports performance may contribute to punching performance in boxers. We compared the effects of two typical boxing routines for developing lower extremity sports performance and subsequent punching performance. Twenty-four high school amateur boxers between the ages of 12 and 18 performed training at least 3 days per week. All Athletes had 3-5 years of experience in boxing training. The participants separated into two groups to receive an 8-week plyometric or jump rope training program. They performed each training program for 30 min on 3 days/week. Lower extremity sports performance in countermovement jump (leg stiffness, jump power, and rate of force development) and jab-cross punching performance (punch velocity, punch force, reaction time, movement time, and ground reaction force) were assessed at pre-and post-training. The data were analyzed using a two-way mixed-design analysis of variance (ANOVA) (group × time). Both training programs improved the rate of force development in countermovement jump, the reaction time of punch, the peak ground reaction force of the rear leg during the jab punch, and the velocity of the jab punch. There were no group differences and interaction effects in all variables analyzed. It is concluded that 8 weeks of plyometric and rope jumping programs had a similar impact on improving lower extremity strength and punching performance. Both training programs may improve muscle strength and power, rate of force development, and reaction time. These improvements may contribute to lower extremity strength for driving a punch at the target with excellent performance.
提高下肢运动表现可能有助于提升拳击运动员的出拳表现。我们比较了两种典型的拳击训练方法对发展下肢运动表现及后续出拳表现的影响。24名年龄在12至18岁之间的高中业余拳击手每周至少训练3天。所有运动员都有3至5年的拳击训练经验。参与者被分为两组，分别接受为期8周的增强式训练或跳绳训练计划。他们每周3天，每次进行30分钟的每个训练计划。在训练前和训练后评估了纵跳（腿部刚度、跳跃力量和力量发展速率）中的下肢运动表现以及刺拳-交叉拳出拳表现（出拳速度、出拳力量、反应时间、动作时间和地面反作用力）。使用双向混合设计方差分析（ANOVA）（组×时间）对数据进行分析。两种训练计划均提高了纵跳中的力量发展速率、出拳的反应时间、刺拳时后腿的峰值地面反作用力以及刺拳的速度。在所有分析变量中均未发现组间差异和交互作用。得出的结论是，为期8周的增强式训练和跳绳训练计划对改善下肢力量和出拳表现具有相似的影响。两种训练计划都可能提高肌肉力量和功率、力量发展速率以及反应时间。这些改善可能有助于增强下肢力量，从而以出色的表现朝着目标出拳。
