摘要 Moral-Muñoz, JA、Esteban-Moreno, B、Arroyo-Morales, M、Cobo, MJ 和 Herrera-Viedma, E。用于评估青少年腿筋灵活性的面对面和免费软件视频分析之间的协议。 J Strength Cond Res 29(9): 2661–2665, 2015——本研究的目的是确定青少年面对面腿筋柔韧性测量和免费软件视频分析之间的一致性程度。腿筋灵活性降低在青少年中很常见（10 岁男孩中 75%，女孩中 35%）。腿筋肌肉的长度对于人体基本运动的有效性和效率都具有重要作用，而腿筋灵活性的降低与各种肌肉骨骼状况有关。有多种方法可以高可靠性地测量腘绳肌灵活性；科学文献中最常用的方法是坐姿前屈测试、髋关节角度 (HJA) 和主动膝关节伸展。使用视频分析评估腿筋柔韧性有助于青少年柔韧性的跟踪。来自当地一所学校的 54 名青少年参与了一项使用交叉设计的重复测量的描述性研究。使用倾斜仪测量主动膝关节伸展和 HJA，并用摄像机同时记录。每个视频都被下载到计算机上，然后使用 Kinovea 0.8.15（一款用于运动分析的免费软件应用程序）进行分析。所有结果测量均显示可靠性估计 &agr; > 0.90。 HJA 的可靠性最低 (&agr; = 0.91)。初步研究结果支持使用免费软件工具来评估腿筋灵活性，为卫生专业人员提供青少年灵活性跟踪的有用工具。
Abstract Moral-Muñoz, JA, Esteban-Moreno, B, Arroyo-Morales, M, Cobo, MJ, and Herrera-Viedma, E. Agreement between face-to-face and free software video analysis for assessing hamstring flexibility in adolescents. J Strength Cond Res 29(9): 2661–2665, 2015—The objective of this study was to determine the level of agreement between face-to-face hamstring flexibility measurements and free software video analysis in adolescents. Reduced hamstring flexibility is common in adolescents (75% of boys and 35% of girls aged 10). The length of the hamstring muscle has an important role in both the effectiveness and the efficiency of basic human movements, and reduced hamstring flexibility is related to various musculoskeletal conditions. There are various approaches to measuring hamstring flexibility with high reliability; the most commonly used approaches in the scientific literature are the sit-and-reach test, hip joint angle (HJA), and active knee extension. The assessment of hamstring flexibility using video analysis could help with adolescent flexibility follow-up. Fifty-four adolescents from a local school participated in a descriptive study of repeated measures using a crossover design. Active knee extension and HJA were measured with an inclinometer and were simultaneously recorded with a video camera. Each video was downloaded to a computer and subsequently analyzed using Kinovea 0.8.15, a free software application for movement analysis. All outcome measures showed reliability estimates with &agr; > 0.90. The lowest reliability was obtained for HJA (&agr; = 0.91). The preliminary findings support the use of a free software tool for assessing hamstring flexibility, offering health professionals a useful tool for adolescent flexibility follow-up.
