Abstract:
Aim: The aim of this paper is to determine the effect of 6 weeks of plyometric training on speed, explosive power, pre-planned agility, and reactive agility in young tennis players. Methods: The participants in this study included 35 male tennis players (age 12.14 ± 1.3 years, height 157.35 ± 9.53 cm and body mass 45.84 ± 8.43 kg at the beginning of the experiment). The biological age was calculated and determined for all participants. 18 of the participants were randomly assigned to the control group, and 17 were assigned to the experimental group. Running speed (sprints at 5, 10, and 20 m), change of direction speed (4 × 10, 20 yards, t-test, TENCODS), reactive agility (TENRAG), and explosive power (long jump, single leg triple jump, countermovement jump, squat jump, and single leg countermovement jump) were all tested. The Mixed model (2 × 2) ANOVA was used to determine the interactions and influence of a training program on test results. Furthermore, Bonferroni post hoc test was performed on variables with significant time*group interactions. Results: The results of this research indicate that an experimental training program affected results in a set time period, i.e. 5 out of total 15 variables showed significant improvement after experimental protocol when final testing was conducted. The experimental group showed significantly improved results in the 5 m sprint test in the final testing phase compared to the initial testing phase, this was also the case in comparison to the control group in both measurements. Furthermore, the experimental group showed significant improvement in the single leg countermovement jump in the final test, as well as in comparison to the control group in both measurements. The change of direction speed and reactive agility test also exhibited significant improvement in the final testing phase of the experimental group. Conclusion: The results of this research indicated that a 6-week program dominated by plyometric training can have a significant effect on the improvement of specific motor abilities within younger competitive categories. These results offer valuable insights for coaches in designing diverse tennis-specific scenarios to enhance overall performance, particularly focusing on the neuromuscular fitness of their players.
摘要:
目的:本文的目的是确定6周的丰满训练对速度的影响,爆发力,预先计划的敏捷性,年轻网球运动员的反应敏捷。方法:本研究的参与者包括35名男性网球运动员(年龄12.14±1.3岁,身高157.35±9.53cm,实验开始时体重45.84±8.43kg)。计算并确定所有参与者的生物学年龄。其中18名参与者被随机分配到对照组,17人被分配到实验组。运行速度(5、10和20m处的冲刺),方向变化速度(4×10,20码,t检验,TENCODS),反应性敏捷性(TENRAG),和爆发力(跳远,单腿三级跳远,反运动跳跃,蹲着跳,和单腿逆运动跳跃)都进行了测试。混合模型(2×2)ANOVA用于确定训练程序对测试结果的相互作用和影响。此外,对具有显著时间*组相互作用的变量进行Bonferroni事后检验。结果:这项研究的结果表明,实验训练计划在设定的时间段内影响结果,即,当进行最终测试时,在实验方案之后,总共15个变量中的5个显示出显著的改善。实验组在最终测试阶段的5m冲刺测试中与初始测试阶段相比,结果显着提高,在两项测量中,与对照组相比也是如此.此外,实验组在最终测试中表现出单腿反动跳跃的显着改善,以及在两个测量中与对照组相比。在实验组的最终测试阶段,方向速度和反应性敏捷性测试的变化也显示出显着的改善。结论:这项研究的结果表明,以平衡训练为主导的为期6周的计划可以对年轻竞争类别中特定运动能力的提高产生重大影响。这些结果为教练设计各种网球特定场景以提高整体表现提供了有价值的见解,特别关注球员的神经肌肉适应性。
