The isometric mid-thigh pull (IMTP) is a multi-joint test of whole-body force production relevant to rugby players. "Rugby AND (mid-thigh pull OR midthigh pull OR mid thigh pull" were searched in PubMed, Sportdiscus, Academic Search Premier, CINAHL Plus with Full Text, and Google Scholar; the final date of search was 24 January 2018. Data extraction from 24 articles included subject characteristics, force data, and IMTP testing procedures. Select ranges of peak forces reported were: Youth: 1162-2374 N; Academy: 1855-3104 N; Professional: 2254-3851 N. Rate of force development (RFD) at 100 and 200 ms ranged from 5521 to 11,892 N and 5403 to 8405 N, respectively, among professional rugby players. Studies' research design were of moderate quality, but most studies lacked detailed reporting of IMTP procedures. Variability of force characteristics derived from the IMTP within similar populations (e.g., approximately 200% difference in peak force between samples of professional rugby league players) as well as large and unexpected overlaps between dissimilar populations, limit conclusions about force production capabilities relative to playing level, likely due to limitations and lack of standardization of IMTP procedures. Greater uniformity in IMTP testing procedures and reporting is needed. This manuscript provides a guide for reporting needs when presenting results from an IMTP in research.
等长股中拉（IMTP）是一项与橄榄球运动员相关的全身力量产生的多关节测试。在PubMed、Sportdiscus、学术搜索高级版、全文版CINAHL Plus和谷歌学术中搜索了“橄榄球 AND（股中拉 OR 中大腿拉 OR 大腿中部拉）”；搜索的截止日期为2018年1月24日。从24篇文章中提取的数据包括受试者特征、力量数据和IMTP测试程序。报告的峰值力量的选定范围为：青少年：1162 - 2374牛；学院球员：1855 - 3104牛；职业球员：2254 - 3851牛。在职业橄榄球运动员中，100毫秒和200毫秒时的力量发展速率（RFD）分别为5521至11892牛和5403至8405牛。研究的研究设计质量中等，但大多数研究缺乏对IMTP程序的详细报告。在相似人群中由IMTP得出的力量特征的变异性（例如，职业橄榄球联盟球员样本之间的峰值力量相差约200%）以及不同人群之间大的和意外的重叠，限制了关于相对于比赛水平的力量产生能力的结论，这可能是由于IMTP程序的局限性和缺乏标准化。需要在IMTP测试程序和报告方面有更大的一致性。本手稿为在研究中呈现IMTP结果时的报告需求提供了指导。
