1.1 本试验方法涵盖了跑步过程中下肢某些角运动的测量，特别是小腿相对于脚的旋前和旋后的正面投影（“后脚运动”），以及比较不同跑鞋对后脚运动影响的方法。 1.2 在本试验方法中，鞋类可指跑鞋、矫正鞋垫（矫形器）或两者的特定组合。矫形器的效果可能因鞋而异。因此，涉及矫形器的比较应根据测试鞋子的具体款式进行。 1.3 本试验方法仅限于测量小腿和脚之间相对角运动的二维正面投影（“后脚运动”）。 它不是旋前或旋后的直接测量，旋前或旋后是三维运动。 1.4 该测试方法仅限于脚跟在每一步中第一次接触地面的跑步运动。 1.5 本试验方法适用于受试者在跑步机上跑步或在受控条件下在地面上跑步时的后脚运动测量。 1.6 以国际单位制表示的数值应视为标准。括号中的英寸-磅单位仅供参考。 1.7 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法允许比较跑鞋或鞋内矫正矫形器的后足控制特性，前提是它们同时在相同条件下进行试验。 5.2 这类测试通常用于跑鞋和其他鞋内设备的开发和性能测试。仔细遵守本试验的要求和建议应提供可在不同实验室之间进行比较的结果。 注1: 由于鞋子之间的差异，后脚运动的差异通常小于受试者之间的差异。因此，在不同实验中测试的鞋子之间进行直接比较是不可能的。

1.1 This test method covers the measurement of certain angular motions of the lower extremity during running, specifically, the frontal plane projection of the pronation and supination of the lower leg relative to the foot (“rearfoot motion”) and methods by which the effects of different running shoes on rearfoot motion may be compared. 1.2 As used in this test method, footwear may refer to running shoes, corrective shoe inserts (orthoses) or specific combinations of both. The effects of orthoses may vary from shoe to shoe. Therefore, comparisons involving orthoses shall be qualified by the specific style of shoes in which they are tested. 1.3 This test method is limited to the measurement of the two dimensional, frontal plane projection of the relative angular motion between the lower leg and the foot (“rearfoot motion”). It is not a direct measure of pronation or supination, which are three dimensional motions. 1.4 This test method is limited to running motions in which the heel makes first contact with the ground during each step. 1.5 This test method is applicable to measurements of rearfoot motion made while subjects run on a treadmill or while they run overground under controlled conditions. 1.6 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method allows the rearfoot control properties of running shoes or corrective orthoses within shoes to be compared provided they are tested concurrently and under identical conditions. 5.2 Tests of this type are commonly used in the development and performance testing of running shoes and other in-shoe devices. Careful adherence to the requirements and recommendations of this test shall provide results which can be compared between different laboratories. Note 1: The variance in rearfoot motion due to differences between shoes is generally smaller than the variance between subjects. Direct comparisons between shoes tested in different experiments is therefore not possible.
