METHODS: PubMed, Scopus and ScienceDirect databases were searched from inception to October 19, 2023. Studies were eligible if the objective was finding normative or reference scores for the LESS, analyze the differences between sexes or sports, or used some variant of the test. Results were limited to available full-text articles published in English in peer-reviewed journals.
RESULTS: Of the 360 articles identified, 20 were included for a full analysis (18,093 participants, age = 8-30 years, males = 70.6%). The military population was the most frequently analyzed (7 studies, n = 16,603). Results showed six variants of the LESS and average values ranged from 2.56 to 7.1. Males and females showed different pattern landing with errors in different planes.
CONCLUSIONS: Our findings highlight the need for more field studies on LESS reference scores, particularly for females and basketball or hockey players. Further research is required before conducting a systematic review and meta-analysis.
方法:PubMed,从成立到2023年10月19日,搜索了Scopus和ScienceDirect数据库。如果目标是为LESS找到规范或参考分数,则研究符合资格,分析性别或运动之间的差异,或者使用了测试的一些变体。结果仅限于在同行评审期刊上以英文发表的全文文章。
结果:在确定的360篇文章中,20人被纳入全面分析(18,093名参与者,年龄=8-30岁,男性=70.6%)。军事人口是最频繁分析的(7项研究,n=16,603)。结果显示LESS的六个变体,并且平均值在2.56至7.1的范围内。男性和女性表现出不同的着陆模式,在不同的平面上出现错误。
结论:我们的研究结果强调需要更多关于LESS参考分数的实地研究,特别是女性和篮球或曲棍球运动员。在进行系统评价和荟萃分析之前,需要进一步的研究。
