Plyometric training (PT) has been researched extensively in athletic populations. However, the effects of PT on tennis players are less clear. We aim to consolidate the existing research on the effects of PT on healthy tennis players' skill and physical performance. On 30th May 2022, a comprehensive search of SCOPUS, PubMed, Web of Science, and SPORTDiscus ( EBSCOhost) databases was performed. PICOS was employed to define the inclusion criteria: 1) healthy tennis players; 2) a PT program; 3) compared a plyometric intervention to a control group or another exercise group, and single-group trials; 4) tested at least one measures of tennis skill or physical performance; and 5) non-randomized study trials and randomized control designs. Individual studies' methodological quality was evaluated by using the Cochrane RoB-2 and ROBINS-I instruments. Using Grading of Recommendations Assessment, Development, and Evaluation (GRADE), the certainty of the body of evidence for each outcome was assessed, and Comprehensive Meta-Analysis software was employed for the meta-analysis. Twelve studies comprising 443 tennis players aged 12.5-25 years were eligible for inclusion. The PT lasted from 3 to 9 weeks. Eight studies provided data to allow for the pooling of results in a meta-analysis. A moderate positive effect was detected for PT programs on maximal serve velocity (ES = 0.75; < 0.0001). In terms of measures of physical performance, small to moderate (ES = 0.43-0.88; = 0.046 to < 0.001) effects were noted for sprint speed, lower extremity muscle power, and agility. While no significant and small effect was noted for lower extremity muscle strength (ES = 0.30; = 0.115). We found no definitive evidence that PT changed other parameters (i.e., serve accuracy, upper extremity power and strength, reaction time, and aerobic endurance). Based on GRADE, the certainty of evidence across the included studies varied from very low to moderate. PT may improve maximal serve velocity and physical performance components (sprint speed, lower extremity muscular power, and agility) for healthy tennis players; however, more high-quality evidence about the effects of PT on the skill and physical performance of tennis players merits further investigation.

增强式训练（PT）在运动员群体中已得到广泛研究。然而，PT对网球运动员的影响尚不太明确。我们旨在整合现有关于PT对健康网球运动员技能和身体表现影响的研究。2022年5月30日，我们对SCOPUS、PubMed、科学网和SPORTDiscus（EBSCOhost）数据库进行了全面检索。采用PICOS来定义纳入标准：1）健康的网球运动员；2）一个PT项目；3）将增强式训练干预与对照组或另一个运动组进行比较，以及单组试验；4）测试至少一项网球技能或身体表现指标；5）非随机研究试验和随机对照设计。使用Cochrane RoB - 2和ROBINS - I工具评估个体研究的方法学质量。采用推荐分级评估、制定和评价（GRADE）方法评估每个结果的证据体的确定性，并使用综合荟萃分析软件进行荟萃分析。12项研究纳入了443名年龄在12.5至25岁之间的网球运动员。PT持续3至9周。8项研究提供了数据以便在荟萃分析中汇总结果。对于PT项目对最大发球速度的影响，检测到中等程度的积极效应（ES = 0.75；P < 0.0001）。在身体表现指标方面，对于短跑速度、下肢肌肉力量和敏捷性，观察到小到中等程度的效应（ES = 0.43 - 0.88；P = 0.046至P < 0.001）。而对于下肢肌肉力量，未观察到显著的小效应（ES = 0.30；P = 0.115）。我们没有找到确凿证据表明PT改变了其他参数（即发球准确性、上肢力量和爆发力、反应时间以及有氧耐力）。基于GRADE，纳入研究中证据的确定性从极低到中等不等。PT可能会提高健康网球运动员的最大发球速度和身体表现指标（短跑速度、下肢肌肉力量和敏捷性）；然而，关于PT对网球运动员技能和身体表现影响的更多高质量证据值得进一步研究。[https://inplasy.com/]，标识符[INPLASY202250146]
