Backward walking has gained popularity as an adjunct to treatment for patients undergoing rehabilitation for patellofemoral pain syndrome and anterior cruciate ligament injuries. Researchers have suggested that backward walking decreases the compressive forces at the patellofemoral joint while also preventing overstretching of the anterior cruciate ligament. Prior to this study, precise prescription of backward walking speeds for women was not possible. The purpose of this study was to determine the relationship between heart rate, oxygen consumption, and backward walking speeds. Twenty-five healthy, adult female volunteers participated in this study. Subjects were tested at speeds of 0.96, 1.20, 1.43, 1.67, and 1.91 m/sec. Subjects also performed a graded exercise stress test. Analysis revealed curvilinear relationships between oxygen consumption and speed as well as between heart rate and speed. With these results, clinicians may now prescribe specific speeds of backward walking for women to elicit a desired cardiopulmonary response.
倒走作为髌股疼痛综合征和前交叉韧带损伤康复治疗的辅助手段已越来越受欢迎。研究人员认为，倒走可降低髌股关节的压力，同时防止前交叉韧带过度拉伸。在本研究之前，无法为女性精确规定倒走速度。本研究的目的是确定心率、耗氧量与倒走速度之间的关系。25名健康成年女性志愿者参与了本研究。受试者分别以0.96、1.20、1.43、1.67和1.91米/秒的速度进行测试。受试者还进行了分级运动应激试验。分析揭示了耗氧量与速度之间以及心率与速度之间的曲线关系。基于这些结果，临床医生现在可以为女性开出特定的倒走速度，以引发预期的心肺反应。
