Walking, more specifically gait, is an essential component of daily living. Walking is a very different activity for individuals with a Body Mass Index (BMI) of 40 or more (Class III obesity) compared with those who are overweight or obese with a BMI between 26-35. Yet all obesity weight classes receive the same physical activity guidelines and recommendations. This observational study examined the components of function and disability in a group with Class III obesity and a group that is overweight or has Class I obesity. Significant differences were found between the groups in the areas of gait, body size, health condition, and activity capacity and participation. The Timed Up and Go test, gait velocity, hip circumference, and stance width appear to be most predictive of activity capacity as observed during gait assessment. The findings indicate that Class III-related gait is pathologic and not a normal adaptation.
行走，更确切地说是步态，是日常生活的重要组成部分。与体重指数（BMI）在26至35之间的超重或肥胖个体相比，BMI为40或更高（III级肥胖）的个体的行走是一项截然不同的活动。然而，所有肥胖体重类别都接受相同的身体活动指南和建议。这项观察性研究检查了III级肥胖组以及超重或患有I级肥胖组的功能和残疾组成部分。在步态、体型、健康状况以及活动能力和参与度等方面，两组之间存在显著差异。在步态评估中观察到，计时起立行走测试、步态速度、臀围和站立宽度似乎最能预测活动能力。研究结果表明，与III级肥胖相关的步态是病理性的，而非正常适应。
