■跳跃和着陆测试经常被用作评估肌肉功能的工具。然而,它们是在受控和可预测的环境中执行的。与特定于游戏的动作相比,通常用作受伤后恢复运动标准的一部分的身体测试通常很少或没有认知负荷,并且协调需求较低。这项系统评价的目的是研究在跳跃着陆测试中执行双重任务(DT)或运动特定任务约束对与团队运动中下肢受伤风险相关的生物力学变量的影响。
■本系统评价遵循系统评价和荟萃分析(PRISMA)首选报告项目的具体方法指南。搜索是在Medline(PubMed)数据库中进行的,WebofScience,CochranePlus,和SportDiscus从2013年到2023年6月30日发表的研究。有资格,研究必须包括:(1)下肢损伤危险因素的运动学和/或动力学评估;(2)简单跳跃或着陆测试与包括认知信息的DT跳跃或着陆测试之间的比较.使用Cochrane合作组织的建议分析了选定文章中的偏倚风险。
■在确定的656条记录中,13符合既定标准。此外,在筛选纳入的文章和以前的相关系统综述的参考文献后,我们手动纳入了另外两篇文章.关于偏见风险评估,12项研究没有超过3分(共7项)。只有三项研究超过3分,一篇文章总分6分。从纳入的研究来看,比较条件包括受包含运动球影响的动作(n=6),在虚拟环境中或使用虚拟反馈(n=2)执行任务,参与认知任务(n=6),和涉及双重过程的任务(n=7)。在跳跃着陆动作期间执行决策(DM)导致生物力学变化,例如髋关节屈曲和膝关节屈曲的较低峰值角度,随着垂直地面反作用力的增加,膝盖外展,和胫骨内旋。关于限制,在定义什么是DT时出现了差异。因此,本综述中包含的所有研究可能都不符合DT的所有概念定义.在跳跃着陆测试中加入DT或约束会显着改变与团队运动中下肢受伤风险相关的生物力学变量。在未来的研究中,将任务纳入模拟团队运动特定认知需求的跳跃测试将是有益的。该系统评价在PROSPERO(注册号:CRD42023462102)中注册,该研究没有获得外部资助。
UNASSIGNED: Jumping and landing tests are frequently used as a tool to assess muscle function. However, they are performed in a controlled and predictable environment. The physical tests commonly used as part of the criteria for return to sport after injury are often performed with little or no cognitive load and low coordinative demand compared to game-specific actions. The aim of this systematic
review was to examine the influence of performing a dual task (DT) or sport-specific task constrains during jump-landing tests on biomechanical variables related to lower limb injury risk in team sports.
UNASSIGNED: This systematic
review followed the specific methodological guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search was conducted in the databases Medline (PubMed), Web of Science, Cochrane Plus, and SportDiscus for studies published from 2013 until June 30, 2023. To be eligible, studies had to include: (1) kinematic and/or kinetic assessment of injury risk factors in the lower extremity; (2) a comparison between a simple jump or landing test and a DT jump or landing test which included cognitive information. The risk of bias in the selected articles was analyzed using the recommendations of the Cochrane Collaboration.
UNASSIGNED: Of the 656 records identified, 13 met the established criteria. Additionally, two more articles were manually included after screening references from the included articles and previous related systematic reviews. Regarding the Risk of bias assessment, 12 studies did not surpass a score of 3 points (out of a total of 7). Only three studies exceeded a score of 3 points, with one article achieving a total score of 6. From the included studies, comparative conditions included actions influenced by the inclusion of a sports ball (n = 6), performing tasks in virtual environments or with virtual feedback (n = 2), participation in cognitive tasks (n = 6), and tasks involving dual processes (n = 7). The execution of decision-making (DM) during the jump-landing action resulted in biomechanical changes such as lower peak angles of hip flexion and knee flexion, along with increased vertical ground reaction force, knee abduction, and tibial internal rotation. Regarding limitations, discrepancies arise in defining what constitutes DT. As a result, it is possible that not all studies included in this
review fit all conceptual definitions of DT. The inclusion of DT or constraints in jump-landing tests significantly alters biomechanical variables related to lower extremity injury risk in team sports. In future research, it would be beneficial to incorporate tasks into jumping tests that simulate the specific cognitive demands of team sports. This systematic
review was registered in PROSPERO (registration number: CRD42023462102) and this research received no external funding.
